Note:

|(1) | As of December 31, 2008, we discontinued our optical pickup unit, or OPU, business which had been included within electronic and optical components. As
of September 30, 2009, we discontinued our semiconductor manufacturing equipment, or SME, business which had been included within machinery. The operating results of the OPU and SME businesses and exit costs with related taxes were
recorded as net loss on discontinued operations in the consolidated statement of income in accordance with ASC 205-20 Presentation of Financial Statements-Discontinued Operations (formerly SFAS No.144, Accounting for
the impairment or disposal of Long-Lived Assets). All prior period OPU and SME amounts in the above table, except for the balance sheet data, have also been so reclassified as to enable comparisons between the relevant amounts for the fiscal
years ended March 31, 2006 through 2009.

##### Table of Contents

Fluctuations in exchange rates between the Japanese yen and the U.S. dollar and other
currencies will affect the U.S. dollar and other currency equivalents of the yen price of our shares and ADSs and the U.S. dollar amounts received on conversion of cash dividends. We have translated some Japanese yen amounts presented in this annual
report into U.S. dollars solely for your convenience. Unless otherwise noted, the rate used for the translations was ¥93.04 per $1.00, which was an approximate exchange rate in Japan on March 31, 2010. These translations do not imply
that the yen amounts actually represent, or have been or could be converted into, equivalent amounts in U.S. dollars at these rates or at all.

D. Risk Factors.

If any of the risks described below actually occurs, our business, financial condition or results of operations could be adversely
affected.

Our customer base is highly concentrated, and our sales would suffer if one or more of our significant customers
substantially reduce or cancel orders for our products.

We are dependent on a limited number of large customers for a
substantial portion of our net sales. Sales to our largest customer, Seagate Technology LLC, were approximately 11%, 10% and 11% of total net sales for the years ended March 31, 2008, 2009 and 2010, respectively. Sales to our top six customers
represented approximately 37%, 36% and 41% of our net sales for the years ended March 31, 2008, 2009 and 2010, respectively, and the six customers also represented ¥47.6 billion, or 32%, ¥36.7 billion, or 33%, and ¥61.6 billion, or
41%, of our gross accounts receivable at March 31, 2008, 2009 and 2010, respectively. Moreover, most of our sales to the six largest customers relate to motors used in hard disk drives, or HDDs. As a result of customer concentration, our net
sales could be significantly impacted in the event of:



| |  |  | a significant reduction, delay or cancellation of orders from one or more of our significant customers;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | a decision by one or more of our significant customers to select products manufactured or technologies developed by a competitor, or its own internally
developed components, for inclusion in future product generations; or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | financial difficulties affecting one or more of our significant customers.
| | - |  | --------------------------------------------------------------------------

We expect that, for the foreseeable future, sales to a limited number of customers will continue to account for a high percentage of our
net sales. If current customers do not continue to place orders, we may not be able to replace those orders with orders from new customers, and this would significantly impact our business, operating results and financial condition.

In addition, because there are only a limited number of hard disk drive manufacturers in the world, if one or more of our customers merge
with or are otherwise acquired by another hard disk drive manufacturer, our business could be adversely affected to the extent that the downward pricing pressure increases or actual or potential sales are lost as a result of the surviving
manufacturers decision not to purchase our products.

Because of our dependence on the computer industry, our business may be
adversely affected by a decline in the computer market.

A substantial portion of our net sales depends on sales of
computers and computer peripherals that incorporate our products, including small precision motors. Although we have been diversifying our products and entering into new markets, such as motors for use in home appliances and automobiles, we expect
to continue to derive a significant portion of our revenues from the sale of products for use in computers and computer peripherals. The markets for computers and computer peripherals are cyclical and have been characterized by:



| |  |  | rapid technological change;
| | - |  | ---------------------------



| |  |  | frequent new product introductions and short product life cycles;
| | - |  | -----------------------------------------------------------------



| |  |  | significant price competition and price erosion;
| | - |  | ------------------------------------------------

##### Table of Contents

| |  |  | fluctuating inventory levels;
| | - |  | -----------------------------



| |  |  | alternating periods of over-capacity and capacity constraints due, in part, to cyclical and seasonal market patterns;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | variations in manufacturing costs and yields; and
| | - |  | -------------------------------------------------



| |  |  | significant expenditures for manufacturing equipment and product development.
| | - |  | -----------------------------------------------------------------------------

If any of the foregoing factors leads to a decline in the market for computers and computer peripherals, our net sales could decrease,
and our results of operations could be materially and adversely affected.

We derive a substantial portion of our net sales from sales of
spindle motors for hard disc drives, and a decrease in demand for, or prices of, HDDs could harm our business.

Net sales
of spindle motors for HDDs in computers, and digital home appliances, such as DVD recorders, were 30.8%, 29.7%, and 34.7% of our total net sales in 2008, 2009, and 2010, respectively. Reduced demand for, or lower prices of, HDDs could result in a
decrease in our net sales, adversely affecting our results of operations.

During an economic downturn, manufacturers of HDDs
may suspend or reduce purchases of additional inventory from suppliers such as us. The rate of decline in average selling price accelerates when manufacturers lower prices to absorb excess capacity, liquidate excess inventories, restructure or
attempt to increase their market share.

Many of our customers implement a just-in-time inventory control system. Accordingly,
we generally maintain inventory at or near our customers production facilities based on estimated demand. Our inventory was ¥57.5 billion at March 31, 2009 and ¥69.5 billion at March 31, 2010. A substantial amount of capital
and cost is required to maintain inventory sufficient to meet orders from our customers in a timely manner. In addition, our estimates of future customer demand may prove excessive, exposing us to the risk of unsold inventory becoming obsolete and
prices of our products being reduced.

Demand for HDDs may decline as a result of a competing data storage or communications
technology becoming more common. For example, solid state drives, or SSDs, and other non-HDD storage devices may replace HDDs in certain capacity areas if the price per memory capacity for SSDs is reduced in the future to a level competitive with
that for HDDs. SSDs and other new technologies could result in lower demand for HDDs, which in turn could result in reduced sales of our spindle motors.

HDD manufacturers may merge or otherwise restructure their operations and, as part of their restructurings, may seek to reduce costs and
inventories. Such restructurings may result in increasing downward pressure on spindle motor prices, which could reduce our margins. Our customers may also re-allocate their procurement orders to our competitors, which could reduce our sales
volumes. Such restructurings or similar moves by HDD manufacturers could have a material negative impact on our results of operations.

We are facing downward pricing pressure in all markets where we provide our products, and price declines
could reduce our revenues and gross margins.

We expect downward pricing pressure to continue in all markets where we
provide our products. The hard disk drive industry, where competition is particularly harsh, is characterized by rapidly declining selling prices over the life of a product even for those products which are competitive and timely to market. Our
average unit price of spindle motors for HDDs on a Japanese yen basis decreased by approximately 3%, 15% and 15% during the years ended March 31, 2008, 2009 and 2010, respectively. On a U.S. dollar basis, our average unit price of spindle
motors for HDDs decreased by approximately 1%, 3% and 8%, respectively. In general, the selling price of a spindle motor decrease over time as the supply of such products increases and as the existing technology becomes obsolete. Also, intense price
competition among customers may pressure us to lower the prices of our products while the price of raw materials used in our products may increase due to rising demand for such raw materials in emerging economies, which may make it difficult for us
to maintain the current level of profitability. If we are not able to achieve cost reductions, or develop new products with lower production costs, our business, financial condition and results of operations could be adversely impacted.

Also, the general purchaser preference particularly in the computer market has shifted from higher-priced end-products to lower-priced
end-products. If this trend further accelerates, or if the trend continues significantly longer than our expectation, there may be additional downward pricing pressure on our products, and our results of operations may be adversely affected.

If our third party suppliers experience capacity constraints or production failures, our production could be significantly harmed.

We rely on third party suppliers for some of the raw materials, such as aluminum, and some of the equipment, such as
connectors, electric circuits, magnets and other unit assemblies, used in our manufacturing processes. Our production capacity will be limited if one or more of these materials or equipment becomes unavailable or available in reduced quantities due
to increased prices for such materials, financial or operational disruptions or slowdowns suffered by our principal suppliers or shippers or otherwise, or if we are unable to find alternative suppliers or shippers. If our source of materials and
supplies are unavailable for a significant period of time, our operating results will be adversely affected.

We face aggressive
competition both in the markets where we supply our main products and in the markets into which we are attempting to expand our business, which could have a material adverse effect on our business and results of operations.

In the markets where we supply our main products, including small precision motors, we are under intensive price competitive pressure to
reduce our prices as our competitors attempt to expand their market share. In the markets in which we are attempting to expand our market share, including the home appliances and automobile parts markets, we compete with competitors that may have
larger financial, research and development, manufacturing, sales, marketing and service capabilities and sources of support than we do, and that may also have established market recognition and long-standing customer relationships. In emerging
markets, including those for electric and hybrid vehicle control systems, we also face severe competition with other new market entrants as they seek to expand their market shares.

##### Table of Contents

To maintain our competitiveness in the markets where we supply our main products, and to
enhance our competitiveness in the markets into which we are attempting to expand our business, we believe that we should maintain, or may need to increase, our substantial level of investment in research and development, expand our production,
sales and marketing capabilities, enhance services and support, timely develop new products, and further improve our existing products.

We may not be able to successfully compete in all or some of our markets in the future if:



| |  |  | any of our markets develops faster than our expectations due to rapidly increasing demand or otherwise, causing our market share to decline relative to
our competitors who are better able to meet increasing demand or otherwise cope with developing markets;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we are unable to achieve technological advancement necessary for our products to be accepted in the markets;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | our competitors competitive efforts result in technological innovations, improved manufacturing efficiencies or enhanced research and
developmental capabilities, rendering our products and technologies obsolete or uncompetitive; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we are unable to obtain financial, technological, human and other resources necessary to maintain or enhance our investments.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------

Our failure to maintain or enhance our competitive position could result in reduced profitability.

We may be unable to commercialize customized products that satisfy customers needs, or our customers may be unable to commercialize
products that incorporate our products, which could damage our reputation and reduce sales.

Our customers generally
require us to provide customized products within a set delivery timetable. If we are unable to commercialize new product lines including design, manufacture and delivery of customized products, we will not be able to meet our customers needs.
Any future failure to meet significant customer requirements could damage our reputation, result in a decline in our market share and reduction of our sales and profit ratio, and impede the business development of these new products and the
expansion of the products markets.

In addition, if a customer fails to successfully commercialize or sell products that
incorporate in them any customized product which we have invested significant resources to develop, our business and results of operations would be materially adversely affected.

If any defect is discovered in our products, or if any of the end-products in which our
products are incorporated malfunctions, our reputation and results of operations may suffer by lost sales, costs associated with recalls or management distraction.

We manufacture complex, state-of-the-art motors and other electronic products and, as a result, are exposed to potential warranty and
product liability claims arising from alleged or actual defects in our products in the normal course of business. In particular, widespread malfunction of any end-product in which our products are incorporated may lead to consumer dissatisfaction,
recalls and, potentially, lawsuits. If such malfunction is caused by or attributed or alleged to be attributed to defects in our products, our brand image could be damaged, we might be drawn into disputes with our customers, or our results of
operations might be adversely affected by lost sales or costs associated with recalls. In addition, significant financial and human resources might be incurred, and managements attention might be diverted, if we are required to defend
ourselves against legal claims.

We generally maintain insurance against product liability claims, but our insurance coverage
may not be adequate for any potential liability ultimately incurred. In addition, insurance could become unavailable in the future on terms acceptable to us. A successful claim that exceeds our available insurance coverage or a significant product
recall could have a material adverse impact on our financial condition and results of operations.

We rely on production in developing
countries which may become politically or economically unstable and face risks resulting from unanticipated developments in those countries.

We manufacture and sell a large percentage of our products at locations in developing countries such as China, Thailand, the Philippines,
Vietnam, Malaysia, Mexico, and Indonesia, in order to take advantage of more competitive production and supply costs. These countries are still in the process of developing their economic, social and other infrastructures and are susceptible to
various uncertainties. The political, social and economic situations of these countries may not continue to provide an environment in which we can continue to manufacture our products cost-efficiently in proximity to our customers. The governmental
authorities of those areas may impose regulations or restrictions that would make it difficult, impractical or impossible, whether economically, legally or otherwise, for us to conduct our business there.

Furthermore, business activities overseas exposes us to the following various risks related to foreign business transactions, and these
risks may adversely affect our business, operating results, and financial condition.



| |  |  | economic slowdown or downturn in the relevant industries in foreign markets;
| | - |  | ----------------------------------------------------------------------------



| |  |  | international currency fluctuations;
| | - |  | ------------------------------------



| |  |  | general strikes or other disruptions in working conditions;
| | - |  | -----------------------------------------------------------



| |  |  | labor shortage and the labor cost increase, especially in China;
| | - |  | ----------------------------------------------------------------



| |  |  | political instability;
| | - |  | ----------------------



| |  |  | changes in trade restrictions and tariffs;
| | - |  | ------------------------------------------



| |  |  | the difficulties associated with staffing and managing international operations;

| |  |  | significant time and capital required for expanding overseas businesses before achieving capital return.
| | - |  | --------------------------------------------------------------------------------------------------------

Our quarterly operating results do not necessarily indicate a trend of our future operating results.

We have experienced, and expect to continue to experience, fluctuations in sales and operating results from one quarter to the next. As a
result, we believe that quarter-to-quarter comparisons of our operating results are not necessarily meaningful, and that such comparisons cannot be relied upon as indicators of future performance. Our operating results may be subject to significant
quarterly fluctuations as a result of the various factors, including:



| |  |  | fluctuations in product demand as a result of the cyclical and seasonal nature of the industries in which our products are sold and used, including the
computer industry;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | translation effect of exchange rate fluctuations on the results of our overseas subsidiaries and monetary assets and liabilities denominated in foreign
currencies;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the availability and extent of utilization of our manufacturing capacity;
| | - |  | -------------------------------------------------------------------------



| |  |  | changes in our product, customer, or competitor mix, which can occur on short notice;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | cancellation or rescheduling of significant orders, which can occur on short notice;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | deferrals of customer orders in anticipation of new products; and
| | - |  | -----------------------------------------------------------------



| |  |  | component and raw material costs and availability, particularly with respect to components obtained from sole or limited sources which can occur on
short notice.

Because our production and inventory are planned in advance of anticipated customer demand, if actual
demand is significantly smaller than projected, we may suffer losses.

We typically plan our production and inventory
levels based on customers advance orders, commitments or forecasts, as well as our internal assessment and forecasts of customer demand, which are highly unpredictable and can fluctuate substantially, especially if competition becomes more
intense or the demand is reduced due to seasonality or other factors. Our inventory as of March 31, 2010 was 20.9% higher than it was as of March 31, 2009. In order to secure sufficient production scale and productivity, we may also make
capital investments in advance of anticipated customer demand. In addition, in response to anticipated long lead times to obtain inventory and materials from our suppliers, we may from time to time order materials in advance of anticipated customer
demand. This advance investment and ordering may result in excess inventory levels, resulting in unanticipated inventory write-downs if expected orders fail to materialize.

In addition, our operating expenses are relatively fixed, and we thus have limited ability to reduce expenses quickly in response to any
revenue shortfalls resulting from a decrease in demand. Consequently, our operating results will be harmed if our revenues do not meet our revenue projections.

Our growth has been based in part on acquisitions of, or investments in, other companies, and our future growth could be adversely affected if we make
acquisitions or investments that fail to achieve their intended benefits, or if we are unable to find suitable acquisition or investment targets.

We have achieved much of our growth by acquiring and otherwise investing in other companies that have provided us with complementary
technologies and product lines. From time to time, we intend to seek and pursue appropriate opportunities for acquiring and investing in other companies and increasing our ownership interests in the existing affiliates and joint ventures. To the
extent that we are unable to make successful acquisitions or investments, we may not be able to continue to expand our product range and our growth rates could be adversely affected.

Critical to the success of our acquisitions is the ordered, efficient integration of acquired businesses into our organization, which has
in the past required, and may continue to require, significant resources. There can be no assurance that our acquisitions will generate the operational and financial returns we expect. The success of our future acquisitions will depend upon factors
such as:



| |  |  | our ability to manufacture and sell the products of the businesses acquired;
| | - |  | ----------------------------------------------------------------------------



| |  |  | continued demand for these acquired products by our customers;
| | - |  | --------------------------------------------------------------



| |  |  | our ability to integrate the acquired businesses operations, products and personnel;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | our ability to retain key personnel of the acquired businesses;
| | - |  | ---------------------------------------------------------------



| |  |  | our ability to extend our financial and management controls and reporting systems and procedures to acquired businesses;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | accuracy of financial due diligence; and
| | - |  | ----------------------------------------



| |  |  | our ability to identify possible liabilities that could negatively affect our business, operations or reputation during the due diligence process.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

Our new and additional investments in other companies are subject to other uncertainties
that may have a material adverse impact on our business. For example, the fair value of our investments in other companies may be impaired if their business results deteriorate, resulting in a decline in the fair value of their securities that is
other than temporary. Changes in economic policies of local governments, laws and regulations, and accounting rules applicable to companies in which we invest may also have a significant adverse effect on our financial results. In addition, in cases
where we have a non-controlling interest shareholder, we typically cannot control the operations and the assets of the investees or make major decisions without the consent of other shareholders or participants, or at all, and increasing our
shareholding to a controlling stake may not be feasible.

Failure to succeed in acquisitions or investments, or an inability
to find suitable acquisition or investment targets, could have a material adverse effect on our business, results of operations and financial condition.

Our growth places strains on our managerial, operational and financial resources.

Our future success depends on our ability to expand our organization in line with the growth of our business, including the integration of
recently added subsidiaries within the Nidec group. However, our growth has placed, and is expected to continue to place, a significant strain on our managerial, operational and financial resources. Our recent acquisitions and any further growth by
us or our subsidiaries or affiliates, or an increase in the number of our strategic relationships, will increase this strain on our managerial, operational and financial resources. This strain may inhibit our ability to achieve the rapid execution
necessary to successfully implement our business plan.

We rely on our founder, President and CEO, Mr. Shigenobu Nagamori, the loss of
whom could have a material adverse effect on our business.

Our continued success will depend to a significant extent on
the efforts and abilities of our founder and current President and CEO, Mr. Shigenobu Nagamori. Mr. Nagamori is actively engaged in our management and determines our strategic direction, especially with regard to acquisition activities.
While we are in the process of establishing a management structure designed to reduce our dependence on Mr. Nagamori, his sudden departure or reduced attention to us could have a material adverse effect on our operations, financial condition
and operating results.

Any material failure to successfully achieve our corporate objectives or business strategies due to changes in the
economic environment or otherwise may have an adverse impact on our reputation and business.

One of our major corporate
objectives is to contribute to society, and we endeavor to implement various policies to further this objective, including those intended to provide a stable employment environment and create new jobs. We believe such objectives and policies
contribute significantly to building a positive corporate image and brand.

##### Table of Contents

While endeavoring to achieve our corporate objectives, we pursue business strategies that
include, among others, improving profitability primarily through cost reduction measures and simultaneously seeking growth opportunities through expansion of our customer base and product lines. We may, however, be unable to achieve the
profitability or returns expected by management. Changes in the business and economic environments in which we currently operate or aim to operate and other uncertain or unforeseen factors may make it difficult for us to achieve the targets
management has set.

If we are unable to achieve our corporate objectives due to such difficulty, or are compelled by economic
or other factors to adopt measures that are inconsistent with our corporate objectives, we may lose credibility, and our corporate brand may be diminished, adversely affecting our business and results of operations.

We rely on monthly financial data from operating segments that are not prepared on a U.S. GAAP basis and are not comparable between segments, which
potentially reduces the usefulness of this data to us in making management decisions.

We assess our performance and make
operating decisions based on financial information received from the 14 operating segments and others that we report in our consolidated financial statements: Nidec Corporation, Nidec Electronics (Thailand) Co., Ltd., Nidec (Zhejiang) Corporation,
Nidec (Dalian) Limited, Nidec Singapore Pte. Ltd., Nidec (H.K.) Co., Ltd., Nidec Philippines Corporation, Nidec Sankyo Corporation, Nidec Copal Corporation, Nidec Tosok Corporation, Nidec Copal Electronics Corporation, Nidec Servo Corporation, Nidec
Techno Motor Holdings Corporation and Nidec Motors & Actuators. This segmental information is prepared in accordance with the accounting principles in each segments respective country of domicile. For example, Nidec Corporations
operating profit or loss is determined using Japanese GAAP while Nidec Singapore Pte. Ltd. applies Singaporean accounting principles. Therefore, our segment data has not been prepared under U.S. GAAP on a basis that is consistent with the
consolidated financial statements or on any other single basis that is consistent between segments.

In addition, year-end
closing adjustments and other items are not included in segment totals. These aspects of our segment data could make it more difficult for us to evaluate the relative performance of individual segments and our overall operations in a timely manner,
as compared with segment data compiled on a uniform U.S. GAAP basis.

We are subject to various laws and regulations, and our failure to
comply may harm our business.

We conduct our business subject to ongoing regulation and associated regulatory compliance
risks, including the effects of changes in laws, regulations, policies, voluntary codes of practice and interpretations in Japan and other countries in which we conduct our business. Our compliance risk management systems and programs may not be
fully effective in preventing all violations of laws, regulations and rules.

We are subject to environmental regulations such
as those relating to air pollution, water pollution, treatment of hazardous substances, waste management, and soil and groundwater contamination. Our business activities are subject to a wide range of environmental laws and regulations in Japan,
Asia, North America, Europe and other areas. We may be held responsible for payments or other compensation for noncompliance with or otherwise pursuant to applicable environmental regulations, in which case our reputation as well as our results of
operations could be adversely affected. Moreover, if these regulations become more stringent in the future, the amount of capital expenditures and other expenses which might be required to complete remedial actions and to continue to comply with
applicable environmental laws and regulations could increase and be significant, which would materially and adversely affect our business, financial condition and results of operations.

##### Table of Contents

Our business activities are also subject to various other governmental regulations, both
local and international, including antitrust, anti-bribery, intellectual property, consumer protection, taxation, export regulations, tariffs, foreign trade and exchange controls. Because our sales are mostly derived from small precision motor sales
and because we have a dominant market share globally for small precision motors, any regulatory development or measure that affects sales or manufacturing of small precision motors in particular could reduce our sales or otherwise negatively affect
our business. In addition, as our common stock is listed on the Tokyo Stock Exchange and the Osaka Securities Exchange, and American Depositary Shares representing shares of our common stock are listed on the New York Stock Exchange, we must also
comply with applicable securities laws and regulations. Compliance with these and other applicable laws and regulations could require significant financial, human and other resources. Moreover, our failure or inability to comply fully with these and
other applicable laws and regulations could lead to fines, public reprimands, damage to reputation, enforced suspension of operations or, in extreme cases, withdrawal of authorization to operate, adversely affecting our business and results of
operations.

In addition, future developments or changes in laws, regulations, policies, voluntary codes of practice, fiscal
or other policies and their effects are unpredictable and beyond our control. Such developments and changes may require additional financial, administrative and human resources.

We have experienced and may in the future experience difficulties implementing effective internal controls over financial reporting.

As a public company, it is essential for us to have effective internal controls, corporate compliance functions, and accounting systems to
manage our assets and operations. Moreover, under the U.S. Sarbanes-Oxley Act of 2002, which applies by reason of our status as a company subject to the reporting obligations under the U.S. Securities Exchange Act of 1934, we are required to
establish internal control over our financial reporting, and our management is required to assess the effectiveness of our internal control over financial reporting and disclose whether such internal control is effective. Our independent registered
public accounting firm must also conduct an audit on the effectiveness of our internal control over financial reporting. We have also been subject to regulations on internal control over financial reporting under Japanese law since the beginning of
the fiscal year ended March 31, 2009.

Designing and implementing an effective system of internal controls capable of
monitoring and managing our business and operations requires significant management, human and other resources. Once we identify any significant deficiencies or material weaknesses in our internal control systems, we may require additional resources
and incur additional costs for remediating such deficiencies or weaknesses. For example, during the fiscal year ended March 31, 2009, a material weakness in our internal control over financial reporting existed in connection with a
related-party loan during the fiscal year that was not permitted under Section 402 of the U.S. Sarbanes-Oxley Act of 2002. As a result of the identification of the material weakness, we were required to adopt and implement remedial measures
designed to enhance our internal control over financial reporting commencing in that fiscal year. These remedial measures and any future enhancements, however, may not be adequate to prevent similar incidents from occurring or otherwise ensure that
our internal controls are effective.

If management determines that our internal control over financial reporting is not
effective for any period, we may be unable to timely file reports required under the U.S. Securities and Exchange Act of 1934, and our market perception could be negatively affected. Depending on the severity of, and causes and other factors
relating to, a material weakness in internal control over financial reporting, we could be subject to liabilities or sanctions, including enforcement action by the SEC for violations of the U.S. securities laws and by the Japanese Financial Services
Agency for violations of the Financial Instruments and Exchange Law. In addition, we could be restricted in our ability to access U.S., Japan and other markets for capital raising.

We could be harmed by litigation involving patents and other intellectual property rights.

We have patent protection on certain aspects of our technology and also rely on trade secret, copyright and trademark
laws, as well as contractual provisions, to protect our proprietary rights. We face the following risks:



| |  |  | we could incur substantial costs in defending against claims of infringement of the intellectual property of others and such claims could result in
damage awards against us, in orders to pay for the use of previously unrecognized third-party intellectual property or in injunctions preventing us from continuing aspects of our business, which could in turn have a material adverse effect on our
business, financial condition and results of operations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our protective measures may not be adequate to protect our proprietary rights;
| | - |  | ------------------------------------------------------------------------------



| |  |  | other parties, including competitors with substantially greater resources, may independently develop or otherwise acquire equivalent or superior
technology, and we may be required to pay royalties to license the intellectual property of those parties;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | patents may not be issued pursuant to our current or future patent applications, and patents issued pursuant to such applications, or any patents we
own or have licenses to use, may be invalidated, circumvented or challenged;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the rights granted under any such patents may not provide competitive advantages to us or adequately safeguard and maintain our technology;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we could incur substantial costs in seeking enforcement of our patents against infringement or the unauthorized use of our trade secrets, proprietary
know how or other intellectual property by others; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the laws of foreign countries in which our products are manufactured and sold may not protect our products and intellectual property rights to the same

For specific information relating to the intellectual properties disputes that could have an adverse effect on our results of operations,
see Item 4.B. Business OverviewLegal Proceedings.

Leaks of confidential information may adversely affect our
business.

In the normal course of business, we possess personal and other confidential information on our customers, other
companies and other third parties with whom we do business as well as our own confidential information and personal information of our employees. Although we have security measures in place to protect such information, we may be subject to liability
or regulatory action if any of such information is leaked due to human or technical error, unauthorized access or other illegal conduct, or otherwise. Failure to protect confidential information could also lead to a loss of our competitive advantage
and customer and market confidence in us, adversely affecting our business, financial condition and results of operations.

In
addition, there is a risk that our confidential information may be leaked due to human or technical error or illegal conduct by a third party or other causes that are beyond our control. In such cases, including where our competitive advantage is
lost because of the leak, our business, financial condition or results of operations may be adversely affected.

For our business to continue effectively, we will need to attract and retain qualified personnel.

Our business depends on the continued employment of our senior management, engineering and other technical personnel, many of
whom would be extremely difficult to replace. To maintain our current market position and support future growth, we will need to hire, train, integrate and retain significant numbers of additional highly skilled managerial, engineering,
manufacturing, sales, marketing, support and administrative personnel. Competition worldwide for such personnel is extremely intense, and there can be no assurance that we and our affiliates will be able to attract and retain such additional
personnel.

Losses relating to our pension plans and a decline in returns on our plan assets may negatively affect our results of
operations and financial condition.

We have defined benefit pension plans covering substantially all employees in Japan
who meet eligibility requirements. We may incur losses if the fair value of our pension plans assets declines, if the rate of return on our pension assets declines, or if there is a change in the actuarial assumptions on which the calculations
of the projected benefit obligations are based. We may also experience unrecognized service costs in the future due to amendments to existing pension plans. Changes in the interest rate environment and other factors may also adversely affect the
amount of unfunded pension obligations and the resulting annual amortization expense. In addition, the assumptions used in the computation of future pension expenses may not remain constant.

If our goodwill and long-lived assets become impaired, we may be required to record impairment charges, which would adversely affect our financial
results.

We have substantial goodwill and long-lived assets, including plants, property and equipment. In accordance with
U.S. GAAP, we review goodwill annually for impairment and goodwill and long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Goodwill is tested by initially
estimating fair value and then comparing it against the carrying amount. If the carrying amount of a reporting unit exceeds its estimated fair value, we are required to record an impairment loss. In addition, if long-lived assets do not generate
sufficient cash flows, impairment losses will also have to be recognized. Any significant amount of such impairment losses will adversely affect our results of operations and financial condition.

Our results of operations will be negatively affected if we are required to reduce our deferred tax assets.

As part of the process of preparing our consolidated financial statements in accordance with U.S. GAAP, we must assess the likelihood that
our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we must establish a valuation allowance. In the event of a deterioration in market conditions or results of operations,
in which we determine that there is additional uncertainty regarding realization of all or part of our net deferred tax assets, an adjustment to our deferred tax assets would decrease our income during the period in which such determination is made.

Because our sales to overseas customers are denominated predominantly in U.S. dollars, we are exposed to
exchange rate risks that could harm our results of operations.

Sales to customers outside Japan accounted for 70.5%, 68.3%
and 74.3% of our consolidated net sales during the years ended March 31, 2008, 2009 and 2010, respectively. A significant portion of our overseas sales is denominated in currencies other than the Japanese yen, primarily the U.S. dollar. As a
result, the appreciation of the Japanese yen and other currencies against the U.S. dollar will generally have a negative effect on our sales, operating income, and net income. We may experience volatility in our results of operations as a result of
foreign currency exchange rate fluctuations when the results of operations of subsidiaries operating in currencies other than the yen are consolidated into our financial statements, which are reported in yen.

We also experience foreign exchange risk to the extent that our sales and expenses or those of our subsidiaries are denominated in
different currencies. In order to mitigate against this risk, in recent years we have been attempting to offset a portion of our foreign currency revenue by matching the currency of revenue with the currency of expense. For example, if revenue for a
particular product is in U.S. dollars, we attempt to purchase the supplies and resources used to produce that product in U.S. dollars. Nevertheless, we remain exposed to the effects of foreign exchange fluctuations.

Interest rate fluctuations may adversely affect our financial condition.

We have long-term receivables and debt, with fixed and variable rates, and we enter into interest rate swaps and other contracts in order
to stabilize the fair values and cash flows of those receivables and debts. We enter into interest rate swaps and other contracts to reduce our market risk exposure from changes in interest rates. To the extent that their effects are not hedged, we
are exposed to interest rate fluctuation risks which may affect our operational costs, interest expenses, interest income and the value of financial assets and liabilities.

An unexpected drastic decline in the global economies may result in reduced demand for our products.

Demand for our products may be adversely affected by unexpected economic trends in the countries or regions in which our products are
sold. Economic downturns and resulting declines in purchasing activities in markets worldwide may decline demands for our products, and if the harsh economic environment caused by the recent global recession persists, our business, operating results
and financial condition may be adversely affected.

Our ability to collect on our accounts receivable may be adversely affected by our
customers worsening financial conditions.

Our accounts receivable as of March 31, 2010 was 35.8% higher
compared to March 31, 2009. While we are taking measures to mitigate and manage credit risks with respect to our customers and business partners, if changes in the economic conditions of our major markets lead to unexpected levels of
bankruptcies or defaults or otherwise result in our customers being unable to pay for our products on schedule or at all, our operating results and financial condition may be negatively affected.

Decreases in the value of Japanese or foreign stocks may adversely affect our financial results.

We hold Japanese and foreign stocks as part of our investment securities. The value of these stocks are inherently volatile
and may decline substantially due to economic conditions or other factors, potentially resulting in our recording an impairment loss on such securities. Decreases in the value of Japanese or foreign stocks may also reduce stockholders equity
on our balance sheet since, in accordance with U.S. GAAP, we include unrealized holding losses on available-for-sale securities, if any, in our accumulated other comprehensive income or loss, and other-than-temporary declines in market value, are
charged to income for the period when the loss occurs.

If our access to liquidity and capital is restricted, our business could be harmed.

We rely to a large extent on debt and equity financing to finance our operations, capital expenditures and acquisitions of
other companies. If, due to changes in financial market conditions or other factors, financial institutions reduce, terminate or otherwise modify the amounts or terms of their lending or credit lines to us, and if we are unable to find alternative
financing sources on equally or more favorable terms, our business may be materially adversely affected. In addition, if there is a significant downgrade of our credit ratings by one or more credit rating agencies as a result of any deterioration of
our financial condition or if investor demand significantly decreases due to economic downturns or otherwise, we may not be able to access funds when we need them on acceptable terms, our access to capital markets may become more restricted, or the
cost of financing our operations through indebtedness may significantly increase. This could adversely affect our results of operations and financial condition.

Natural disasters, public health issues, armed hostilities, terrorism and other causes over which we have little or no control could harm our
business.

Natural disasters, fires, public health issues, armed hostilities, terrorism and other incidents, whether in
Japan or any other country in which we operate, could cause damage or disruption to us, our suppliers or customers, or could create political or economic instability, any of which could harm our business. For example, several of our facilities in
Japan could be subject to catastrophic loss caused by earthquakes. The spread of unknown infectious diseases, such as a new type of influenza virus, could affect adversely our operations by rendering our employees unable to work, reducing customer
demand or by disrupting our suppliers operations. Our network and information systems are important for normal operations, but such systems are vulnerable to shutdowns caused by unforeseen events such as power outages or natural disasters or
terrorism, hardware or software defects, or computer viruses and computer hacking. Any of these events, over which we have little or no control, could cause a decrease in demand for our products or services, make it difficult or impossible for us to
deliver products or for our suppliers to deliver components, require large expenditures to repair or replace our facilities or create delays and inefficiencies in our supply chain.

We maintain third party insurance coverage for various types of property, casualty and other risks. The types and amounts of insurance
that we obtain vary from time to time and from location to location, depending on its availability and cost and our decisions as to risk retention. Our insurance policies are subject to deductibles, policy limits and exclusions that result in our
retention of a level of risk on a self-insured basis. While we believe our insurance coverage is comparable to the coverage maintained by similar companies in our industry, losses not covered by insurance could be significant, adversely affecting
our financial condition and results of operations.

A substantial number of our shares of common stock are eligible for future sale, and the sale of these
shares may cause our stock price to decline, even if our business is doing well.

As of March 31, 2010, there were
139,290,674 shares of our outstanding common stock (excluding treasury stock), including 20,067,944 shares beneficially owned by our President and CEO, Mr. Shigenobu Nagamori, representing 14.4% of the outstanding shares. These shares and,
generally, the shares owned by other shareholders, can be sold on the Osaka Securities Exchange Co., Ltd., the Tokyo Stock Exchange, Inc. and otherwise in Japan. Additional sales of a substantial amount of our common stock in the public market, or
the perception that sales may occur, could cause the market price of our common stock to decline. This could also impair our ability to raise additional capital through the sale of our securities. Also, in the future, we may issue securities to
raise cash for additional capital expenditures, working capital, research and development or acquisitions. We may also pay for interests in additional subsidiary or affiliated companies by using cash, common stock or both. We may also issue
securities convertible into our common stock. Any of these events may dilute your ownership interest in us and have an adverse impact on the price of our common stock.

Japans unit share system imposes restrictions in holdings of our common stock that do not constitute whole units.

Our Articles of Incorporation provide that 100 shares of our stock constitute one unit. The Company Law of Japan imposes
significant restrictions and limitations on holdings of shares that constitute less than a whole unit. Holders of shares constituting less than a unit do not have the right to vote. A shareholder who owns shares representing less than one unit will
not be able to exercise any rights relating to voting rights, such as the right to participate in a demand for the resignation of a director, the right to participate in a demand for the convocation of a general meeting of shareholders and the right
to join with other shareholders to propose an agenda item to be addressed at a general meeting of shareholders. Under the unit share system, holders of shares constituting less than a unit have the right to require us to purchase their shares.
However, holders of ADSs that represent other than multiples of whole units cannot withdraw the underlying shares representing less than one unit and, therefore, they will be unable to exercise the right to require us to purchase the underlying
shares. As a result, holders of ADSs representing shares in lots of less than one unit may not have access to the Japanese markets to sell their shares through the withdrawal mechanism.

Rights of shareholders under Japanese law may be more limited than under the laws of other jurisdictions.

Our Articles of Incorporation, Regulations of the Board of Directors, Share Handling Regulations and the other related regulations, as
well as the Company Law govern our corporate affairs. Legal principles relating to such matters as the validity of corporate procedures, directors and officers fiduciary duties and shareholders rights may be different from those
that would apply if we were a non-Japanese company. Shareholders rights under Japanese law may not be as extensive as shareholders rights under the laws of other countries or jurisdictions within the United States. You may have more
difficulty in asserting your rights as a shareholder than you would as a shareholder of a corporation organized in another jurisdiction. In addition, Japanese courts may not be willing to enforce liabilities against us in actions brought in Japan
which are based upon the securities laws of the United States or any U.S. state.

A holder of our ADSs will have fewer rights than a shareholder has and will have to act through the
depositary to exercise those rights.

The rights of the shareholders under Japanese law to take actions, including voting
their shares, receiving dividends and distributions, bringing derivative actions, examining our accounting books and records and exercising appraisal rights are available only to holders of record. Because the depositary, through its custodian
agent, is the record holder of the shares underlying the ADSs, only the depositary can exercise those rights in connection with the deposited shares. The depositary will make efforts to vote the shares underlying ADSs as instructed by the ADS holder
and will pay to ADS holders the dividends and distributions collected from us. However, as an ADS holder, you will not be able to bring a derivative action, examine our accounting books and records or exercise appraisal rights in your capacity as
ADS holder.

Because of daily price range limitations under Japanese stock exchange rules, you may not be able to sell your shares of our
common stock at a particular price on any particular trading day, or at all.

Stock prices on Japanese stock exchanges are
determined on a real-time basis by the equilibrium between bids and offers. These exchanges are order-driven markets without specialists or market makers to guide price formation. To prevent excessive volatility, these exchanges set daily upward and
downward price fluctuation limits for each stock, based on the previous days closing price. Although transactions may continue at the upward or downward limit price if the limit price is reached on a particular trading day, no transactions may
take place outside these limits. Consequently, an investor wishing to sell at a price above or below the relevant daily limit may not be able to sell his or her shares at such price on a particular trading day, or at all.

Foreign exchange fluctuations may affect the dollar value of our ADSs and dividends payable to holders of our ADSs.

Market prices for our ADSs may fall if the value of the yen declines against the U.S. dollar. In addition, the U.S. dollar amount of cash
dividends and other cash payments made to holders of our ADSs would be reduced if the value of the yen declines against the U.S. dollar.

It may not be possible for investors to effect service of process within the United States upon us or our Directors or Corporate Auditors or to
enforce against us or these persons judgments obtained in United States courts predicated upon the civil liability provisions of the federal securities laws of the United States.

We are a limited liability, joint-stock corporation incorporated under the laws of Japan. Most of our Directors and Corporate Auditors
reside in Japan. All or substantially all of our assets and the assets of these persons are located in Japan and elsewhere outside the United States. It may not be possible, therefore, for investors to effect service of process within the United
States upon us or these persons or to enforce against us or these persons judgment obtained in United States courts predicated upon the civil liability provisions of the federal securities laws of the United States. There is doubt as to the
enforceability in Japan, in original actions for enforcement of judgments of United States courts, of liabilities predicated solely upon the federal securities laws of the United States.

Item 4. Information on the Company.

A. History and Development of the Company.

Nidec is a joint stock corporation that was incorporated and registered under the Japanese Commercial Code (which was replaced by the
Company Law in May 2006) of Japan on July 23, 1973 under the name of Nihon Densan Kabushiki Kaisha. Our corporate headquarters are located at 338 Kuzetonoshiro-cho, Minami-ku, Kyoto 601-8205, Japan. Our main telephone number is 81-75-935-6140.
As of March 31, 2010, we had 141 subsidiaries located in 19 countries, and an affiliated company located in the Philippines. We had 96,482 employees worldwide, 90.9% of which were employed outside Japan, as of March 31, 2010.

We are one of the leading global manufacturers of electric motors and related components and equipment. We aim to achieve sustainable
business growth by solidifying our leadership position in motor drive technology and expanding our product portfolio into a broader spectrum of the global electric motor market. With a particular focus on brushless DC (Direct Current) motors, we
have constantly explored new ways to serve the global market through the introduction of energy-efficient, environment-friendly motor drives. Our growth as a manufacturer of electric motors to our current size and status has largely been the result
of the acquisition and integration of businesses that have enabled us to build a strong product offering. We regard our ability to identify, purchase and integrate acquisition targets as an essential part of our core strategy and strength.

In August 2009, to enhance our profit from manufacturing and selling sintered-alloy fluid dynamic bearing units, we acquired
all of the voting interests in two joint ventures, NTN-Nidec (Zhejiang) Corporation and NTN-Nidec (Thailand) Co., Ltd., held by our joint venture partner, NTN Corporation in Japan. We and NTN Corporation established the two joint ventures in August
2002 and November 2005, respectively. Prior to our acquisition of the additional voting interests in August 2009, we held 40.0%, and NTN Corporation held, 60.0% of the voting interests in each joint venture. Following the acquisition, these
companies were renamed Nidec Bearing (Zhejiang) Corporation and Nidec Bearing (Thailand) Co., LTD, respectively.

In January
2010, to strengthen our position in the household motor market and to expand our business in Europe, we acquired the household motor business of Appliances Components Companies S.p.A. in Italy through a share purchase transaction. The acquired
business, which was renamed Nidec Sole Motor Corporation S.R.L. following the transaction, became our wholly owned subsidiary.

In February 2010, to meet the increasing demand for hard disk spindle motors, we acquired 75.0% of the outstanding shares of SC WADO Co.,
Ltd. in Thailand, which is a manufacturer of base plates, through a share transfer transaction. As a result of the transaction and a subsequent purchase of additional shares, we currently hold 90.0% of the outstanding shares of SC WADO.

In April, 2010, we and Nidec Servo Corporation, a consolidated subsidiary, entered into a share exchange agreement to make Nidec Servo
our wholly owned subsidiary. The share exchange transaction is expected to become effective on October 1, 2010 in accordance with a resolution adopted at an ordinary general meeting of Nidec Servo shareholders held on June 18, 2010.

Our Business Model and Strategy

We pursue sustainable enhancement of corporate value by leveraging our core competencies in the electric motor drive technology and
associated manufacturing and marketing expertise, which are designed flexibly to align with future changes and developments in the relevant markets.

Our business model is to provide specialized motor drive solutions to global customers who seek to build and maintain a top tier product
portfolio in terms of efficiency, differentiation, price competitiveness and speed to market. The business model has evolved over time in alignment with the customers changing value priorities and based on our strategic foresight in
identifying potential growth areas to concentrate our resources on. We constantly assess our visions and strategies in light of the evolving business environment and, if necessary, seek to reposition ourselves by proactively taking measures,
including investments, mergers and acquisitions, and divestiture or transformation of operations.

As an independent
participant in multiple supply chains in multiple product markets, we supply products to higher-tier suppliers and ODM/OEM customers. We provide our specialized capabilities in motor-drive solutions that customers otherwise do not have direct access
to, or can not cost-effectively create or manage internally. We seek to maintain and further develop these capabilities to compete with our current and potential competitor suppliers worldwide.

The customers in the supply chains we currently serve generally have the following attributes:



| | - |  | They expect highly innovative products with an increasing focus on energy-saving, environmentally-friendly features,
| | - |  | --------------------------------------------------------------------------------------------------------------------



| | - |  | They require large quantities at a low price, and
| | - |  | -------------------------------------------------



| | - |  | They purchase on short notice and expect quick delivery, service and support.
| | - |  | -----------------------------------------------------------------------------

We aim for the highest market share in our chosen areas of operations, and believe that we have developed a flexible and agile
manufacturing framework to ensure rapid responses to changes in customer demand, timely resolution of quality problems, and fast implementation of new product features.

We believe our key strengths and capabilities can be summarized as follows:



| |  |  | Strategic foresight to identify future growth opportunities and challenges, and agility in responding to the accompanying changes in technologies,

| |  |  | Extensive experience in successful mergers and acquisitions and post-merger integration.
| | - |  | ----------------------------------------------------------------------------------------

Our competitive advantages, particularly from a perspective of responsiveness to customers, reflect, and are primarily driven by, the
following operational elements:

Technology

Continuing improvement in product design, manufacturing and process technologies is critical to differentiate ourselves from our
competitors and, from time to time, to ease pricing pressure. We aim to have all of our design activities focus on future growth markets and potential applications well-matched with the context of the times.

From a technical perspective, our business model first demonstrated its validity in establishing our leadership in
the global market for spindle motors for hard disk drives. In the 1980s, the computer industry was seeking innovative solutions that would enable smaller-footprint computer for home and office uses (personal computers, or PCs) without
compromising performance. The manufacturers of the hard disk drive, a storage device used to store digitally encoded data in the computer and server, were also looking for innovative ways to dramatically reduce the size and improve the performance
of their hard disk drives. They needed a new platter, new read/write head, and among all things, a new type of electric motor. We had anticipated the need for smaller yet higher-performing motors early on and successfully developed our proprietary
brushless DC motor technology and associated mass-production expertise ahead of our competitors. Our brushless DC motor quickly replaced the traditional brush-commutated DC motor (brush DC motor) to become the mainstream motor solution for hard disk
drives, and subsequently, optical disk drives.

Our motor drive technology has since evolved through waves of innovation and
modification to fulfill a role fine-tuned to the needs of the times. Exhibiting enhanced rotation accuracy, controllability, lightness, quietness and operating life, coupled with significantly improved energy-efficiency and environmental advantages,
our motor portfolio has extended its reach beyond the information technology field into many other market segments where we find new demand. Our current focus is on new applications arising from consumers preference toward energy-saving
lifestyle, greater comfort and safety. Among the most prospective application areas, we place particular emphasis on electric/hybrid automobiles and home electric appliances, for which we believe highly controllable, energy-saving and
environmentally-friendly motors are increasingly sought after.

Production

Our customers, to a greater or lesser degree, serve various electronics markets which typically require large quantities of high-quality
precision components, including electric motors, on short notice and at competitively low prices. Attaining a sustainable leadership position in these markets is essentially synonymous with having industry-leading manufacturing capacities and
flexible manufacturing techniques that enable competitive quantity, quality, speed and price. For this reason, we constantly explore new application areas with high growth potential to continue securing sufficient production volume for better
economies of scale and scope. Our manufacturing initiatives towards the leading market position basically begin with establishing substantially large manufacturing capacities in close proximity to major groups of customers so that we can meet
quality and quantity demand better and make delivery times shorter than our competitors. Further, we carefully measure the value added along the production lines over the course of time and, at a scale deemed appropriate, standardize and automate
production lines for lower cost manufacturing operations.

Inventory and Delivery

Our major revenue streams currently come from the customers who adopt a just-in-time system (JIT), under which the customers produce only
what is required in the correct quantity and at the correct time, to keep their stock levels to a minimum. Accordingly, we are expected to deliver our products to the customers loading bays within a narrow time slot.

JIT is a very responsive manufacturing method, and yet very reliant on suppliers. If stock is not delivered on time, the customers
entire production schedule would most likely be delayed. Customers without inventory must avoid such a supply system problem that creates a shortage of parts. This makes supplier relationships extremely important for our customers, and our
responsiveness here is primarily measured by our ability to keep sufficient levels of inventory readily available to the customers at many locations worldwide. To fulfill these customer needs, our global manufacturing network is flexibly coordinated
to ensure geographical proximity to the factories and warehouses of our customers. At the same time, we pay significant attention to the demand conditions in downstream markets in order to mitigate the risk of overstocking on our side.

Quality

Our
quality initiatives revolve around continuous improvement and optimization of all processes: from product development, purchasing, production, sales to delivery, in order to provide maximum value for our customers. We adopt quality as a competitive
strategy and implement techniques, such as ISO 9001 certification and statistical process controls, to meet customer demands and improve overall business performance.

As an internationally operating company, our quality responsibility involves reducing the environment burdens of our products and
operations beyond national borders. In addition to compliance with international environmental standards, such as ISO14001, REACH (Registration, Evaluation, Authorization and Restriction of Chemical substances) and RoHS (Restriction of Hazardous
Substances Directive), we seek to address environmental considerations and work on the reduction of raw materials used per unit of product.

Investments

With
a flexible business model designed to adapt to the continuously changing market and economic environment, we have strengthened our market position through strategic investments and acquisitions in potentially higher value areas. Our current focus of
investments is on:



| | - |  | internalization of the production of core parts to improve profitability and mitigate risks attributable to supply chain constraint, and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| | - |  | mergers and acquisitions intended to gain access to new customers and markets.
| | - |  | ------------------------------------------------------------------------------

Proactive investments have helped transform us into a global enterprise with improved
overall productivity and expand our presence in some of the worlds fastest growing markets.

The business model,
supported by our strong entrepreneurship culture and visionary market insights, is designed to deliver stronger earnings and cash flows in rapidly changing economic environments.

Strategy

Electric
motors account for an increasingly larger portion of all electric consumption in the world today. The efficiencies of electric motors and motor drive systems can make a significant difference in the worlds power consumption and would become a
crucial key to accelerating the shift toward clean and renewable energy sources, which originates in increased concerns over supplies of fossil fuels and the imminent effects of climate change.

Inefficient motors result in significant energy waste. With an increase in electricity costs, energy lost due to inefficient motors
essentially translates into economic loss. In addition, since a large portion of the power generated in the world currently comes from the burning of fossil fuels, wasted energy due to motor inefficiency contributes to an increases in the amount of
pollution created in the power generation process. The widespread use of high-efficiency, advanced electric motor solutions is expected to enhance the possibilities of reducing energy costs for end users, reducing the consumption of fossil fuels for
energy production, and decreasing the amount of harmful emissions released into the atmosphere.

In addition to these factors,
we believe the primary catalysts driving demand for highly sophisticated electric motors would include:



| |  |  | advances in electronic support for greater living comfort and safety (e.g., electronic vehicle control and home appliance digitalization), and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Growth in emerging markets.
| | - |  | ---------------------------

The core of our current strategic thinking revolves around how we can contribute to and take advantage of the foregoing market shift by
leveraging our specialized motor technologies, particularly those associated with the brushless DC motor.

A brushless DC
motor is a type of electric motor that uses electronically controlled commutation systems, rather than a mechanical commutation system used in a conventional DC motor. The brushless DC motor, without a commutator and brushes to wear out, essentially
has no attributes negatively affecting the electrical connections and exhibits many advantages over traditional motor types, including:



| |  |  | better speed versus torque characteristics,
| | - |  | -------------------------------------------

| |  |  | higher dynamic response,
| | - |  | ------------------------

| |  |  | higher efficiency,
| | - |  | ------------------

| |  |  | longer operating life,
| | - |  | ----------------------

| |  |  | noiseless operation,
| | - |  | --------------------

| |  |  | higher speed ranges,
| | - |  | --------------------

| |  |  | smaller and lighter (higher ratio of torque delivered to the size of the motor), and
| | - |  | ------------------------------------------------------------------------------------

| |  |  | no ionizing sparks resulting in electromagnetic interference.
| | - |  | -------------------------------------------------------------

Brushless DC motors are gaining popularity and have come to dominate many applications
requiring precise speed control, despite their higher cost compared to conventional motor types. Hard disk drives, optical disk drives and cooling fans for consumer/enterprise computers and DVD recorders/players already use brushless DC motors
exclusively. Higher-torque brushless DC motors are finding their way into hybrid/electric vehicles, home appliances, office equipment and industrial machinery. We believe brushless DC motors can potentially be employed in any area currently
fulfilled by conventional DC motors.

The details of each product category are as follows:

(1) Hard disk drives spindle motors

We manufacture spindle motors for hard disk drives used in personal computers, computer servers, and a range of digital consumer
electronics. This product category represented 61.7% of our Small Precision Motors sales for the fiscal year ended March 31, 2010.

Our hard disk spindle motors fall into three groups based on their hard disk drive form factors, or disk platter diameters, as follows:



| | (a) | 3.5-inch form factorfor desktop PCs, enterprise servers, personal video recorders, or PVRs, digital flat TVs, and external hard disk drives;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | 2.5-inch form factorfor notebook PCs (including ultra mobile PCs), PVRs, game machine consoles, digital flat TVs, and external hard disk drives, and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Sub-1.8-inch form factorfor handheld digital devices.
| | --- | ------------------------------------------------------

We currently supply spindle motors to all of the major hard-disk drive manufacturers in the world. In the fiscal year ended
March 31, 2010, approximately 31% of our hard disk drive spindle motor sales came from Seagate Technology LLC, 29% from Western Digital Corporation, 21% from Hitachi Global Storage Technologies and the remainder from Samsung and Toshiba
Corporation. Substantially all of our sales of hard disk drive spindle motor are denominated in U.S. dollars. In this market we currently compete with three motor suppliers: Alphana Technology Co., Ltd., Minebea Technology Co., Ltd., and Samsung
Electro-Mechanics. Demand for hard disk drive spindle motors typically peaks in the autumn-winter season, driven by corporate IT spending and consumer spending in the back-to-school and holiday shopping seasons.

The following are some of the key recent market trends we consider significant to our hard disk drives spindle motor business.



| |  |  | Emerging markets have expanded to account for an increasingly substantial portion of the increase in PC sales worldwide, offering new demand
opportunities to the PC components manufacturers. Meanwhile, the PC industrys growing dependence on the emerging regions is expected to result in lower PC prices. The resulting shift toward low-cost configuration may further propel PC
commoditization and thereby increase price pressure on the upstream components suppliers.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The industry is undergoing component supply shortage primarily due to (a) strong demand in emerging markets, (b) labor and facility
constraints across supply chains resulting from a massive downsizing in production resource/operations during the economic contraction, and (c) shortage of key raw materials.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Low cost, ultra mobile PCs have come into the mainstream PC category, representing the increasingly price-driven, mobility-conscious market.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The competition with the solid-state disk, or SSD, manufacturers in this field remains an issue of significance for the hard disk drive industry. SSDs
may not be an immediate threat to the hard disk drive supply chain primarily due to extremely high price per gigabyte that substantially diminishes SSDs comparative advantages over hard disk drives. However, the hard disk drive industry
continues to perceive SSDs as a medium- to long-term potential contender under the assumption that SSD manufacturers would eventually overcome existing technical and financial impediments to gain certain cost-competitiveness.

##### Table of Contents

Customers and Competitors

We serve various electric motor markets and compete with a number of different companies depending on the particular product offering. Due
to changing market conditions, our customers and competitors, who historically have made component products for inclusion in their finished goods, have chosen to outsource their requirements to specialized manufacturers, such as us, over the past
several years, in an effort to procure component products more cost effectively. We have been seeking to capitalize on this competitive climate by making acquisitions and increasing our manufacturing efficiencies. In many cases, these acquisitions
have created new opportunities and allowed us to enter new markets in which we had not been involved. We compete primarily on the basis of quality, price, service and our promptness of delivery.

Product Development and Engineering

Each of our business groups has its own product development and design teams that continuously enhance our existing products and develop
new products for our growing base of customers that require custom and standard solutions. We have some of the industrys most sophisticated motor development and testing laboratories, including those for hard disk drive motors and automotive
motors. We believe these capabilities provide a significant competitive advantage in developing high quality motors with leading environmentally friendly design characteristics, such as low noise, improved safety, reliability and energy efficiency.

Manufacturing and Operations

We have developed and acquired overseas operations mainly in Southeast Asian countries, China, and Europe. We manufacture products largely
on our own but depend partly on outsourcing for certain parts and components. While we pursue global sourcing to reduce our overall costs, we generally maintain a dual sourcing capability in our existing domestic facilities to ensure a reliable
supply source for our customers. We regularly invest in machinery and equipment and other improvements to, and maintenance of, our facilities. Additionally, we have obtained significant amounts of quality capital equipment as part of our
acquisitions, often increasing overall capacity and capability. Base materials for our electric motors, which are our core products, consist primarily of aluminum, steel, copper and plastic, whose prices can be volatile. We purchase raw materials
and processed parts from many suppliers and, with a few exceptions, do not rely on any single supplier for any of our base materials. We have also continued to upgrade our manufacturing equipment and processes through the introduction of automated
manufacturing systems, developing our own testing systems.

Government Regulation and Environmental Standards

Our business activities are subject to various governmental regulations in the jurisdictions in which we operate, including those relating
to customs, import and export control, foreign exchange controls, competition or antitrust, intellectual property, environment product safety, and labor.

The following regulations have an important influence on our business.



38

##### Table of Contents

In Japan, we are subject to environmental regulation under the Air Pollution Control Law,
the Water Pollution Control Law, the Wastes Disposal and Public Cleaning Law, the Law for the Promotion of Effective Utilization of Resources, the Basic Law for Establishing a Recycling-based Society and other laws. We are also subject to local
regulations which in some cases impose requirements more stringent than the national requirements. However, we do not use large volumes of hazardous or toxic chemicals in our manufacturing operations. Moreover, our operations do not require the
disposal of large amounts of waste into the environment. Our emissions are sufficiently low so that we are not required to report their amount under the Pollutant Release and Transfer Register.

Our overseas operations are also subject to environmental regulation. Our operations in the United States, for example, are subject to
extensive federal environmental laws and regulations. We are also subject to substantial state legislation that parallels, and in some cases imposes more stringent obligations than, the federal requirements. Any electronic or electrical equipment
sold in the EC are subject to the Restriction of Hazardous Substances Directive (RoHS) 2002/95/EC. This Directive indicates that only products entering the EU must be in compliance. Still, we consider the Directive to essentially cover our whole
lines of products because of the possibility that products we make and sell elsewhere could be eventually destined for the EU as components of other companies products.

Environmental considerations are critical in measuring our product competitiveness. We constantly monitor and adapt to changes in
environmental regulatory requirements for strict compliance. Almost all of our domestic and overseas manufacturing plants have either received, or are scheduled to receive within the next few years, certifications under the ISO 14001 standards on
environmental management systems of the International Organization for Standardization. Also, under a control framework established to eliminate lead from our production process, a predominant portion of our products (with a few exceptions required
by certain customers) currently use lead-free solder.

Intellectual Property

In the ordinary course of business, we regularly file patent applications in Japan, the United States and China. We seek patent protection
in various other foreign countries where our patented technologies are used. In cases where we deem appropriate, we also seek enforcement of our patents. We believe that there is no single patent or group of related patents which are critical to our
principal business segments.

Legal Proceedings

On July 30, 2008, we filed a lawsuit in the Osaka District Court against Samsung Electro-Mechanics Co., Ltd. for infringement of
Japanese Patent Nos. 3344913, 3502266 and 3688015, which relate to our technology used for spindle motors in CD, DVD and Blu-ray drives. After the Osaka District Court issued a decision unfavorable to us on November 26, 2009, on
December 10, 2009, we appealed the district court decision to the Intellectual Property High Court of Japan.

On
September 25, 2008, we filed a lawsuit in the Tokyo District Court against YASKAWA Electric Corporation for infringement of Japanese Patent Nos. 3973006 and 3973048, which relate to LCD panel handling robots. On March 31, 2010, we brought
an additional lawsuit in the Tokyo District Court against YASKAWA Electric for infringement of Japanese Patent No. 3973048 to add additional products of YASKAWA Electric. We have filed a petition for merging these two lawsuits.

These three lawsuits are pending in their respective courts as of March 31, 2010.

##### Table of Contents

We are also involved in several other actions and proceedings in Japan and overseas in the
ordinary course of our business. Based upon the information currently available to us and our domestic and overseas legal counsel, we believe that the ultimate resolution of such actions and proceedings will not, in the aggregate, have a material
adverse effect on our financial condition or results of operations.

During the fiscal year ended March 31, 2009, we
voluntarily brought to the attention of the SEC an issue relating to a related-party loan made by us to S.N. Kohsan, a company indirectly owned by our Chief Executive Officer, in December 2008, which loan was not permitted under Section 402 of
the U.S. Sarbanes-Oxley Act of 2002. The Division of Enforcement of the SEC advised us that it was conducting an informal inquiry into the issue, and we cooperated fully with the informal inquiry. We have subsequently been advised by the Staff of
the Division of Enforcement that its investigation has been concluded and that the Staff will not recommend that enforcement proceedings be commenced. For further information on the related-party loan, see Item 3.D. Risk FactorsWe have
experienced and may in the future experience difficulties implementing effective internal control over financial reporting, Item 7.B. Major Shareholders and Related Party TransactionsRelated Party TransactionsLoan to S.N.
Kohsan and Item 15. Controls and Procedures.

C. Organizational Structure.

Item 5. Operating and Financial Review and Prospects

A. Operating Results.

You should read the following discussion of our financial condition and results of operations together with our consolidated financial
statements and related notes and other information included in this annual report. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from
those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth under Item 3.D Key Information-Risk Factors and elsewhere in this annual report.

Overview

We are a
leading manufacturer of spindle motors for hard disk drives in the world. We manufacture and sell spindle motors for hard disk drives and various other small precision brushless direct current electricity, or DC, motors and other products through 28
subsidiaries in Japan and 113 subsidiaries in other countries, including China, Singapore, Thailand, the United States, Vietnam, Germany, Indonesia, the Philippines, South Korea, Taiwan, Malaysia, Hungary, Spain, Poland, Mexico, France, the
Netherlands and Italy, as of March 31, 2010.

Principal Items in Our Statement of Operations

Net sales-

Our net sales
are generated primarily from the sales of our products. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sale price is fixed and collectability is reasonably assured. As such, revenue is generally
recognized at the time of delivery to customers in domestic sales and at the time of shipment for export sales with respect to small precision motors, mid-size motors and electronic and optical components, and upon receipt of final customer
acceptance with respect to machinery. We maintain data with respect to net sales by product type. We also maintain data with respect to net sales of our products based on the entities which are our operating segments. For a detailed discussion of
our operating segments, see -Segment Information below.

Cost of products sold-

Our cost of sales consists of fixed costs and variable costs, which are primarily material, parts, and manufacturing expenses, including
personnel costs, depreciation, and facility maintenance costs. We periodically assess the market value of our inventory based on sales trends and forecasts and technological changes. We write off inventories when it is apparent that there is no
possibility of future sales or usage. The write off of inventory is recorded as cost of sales. Fixed costs limit our ability to reduce costs in times of decreased demand, which may have an adverse effect on our operating results.

Selling, general and administrative expenses-

Our selling, general and administrative expenses consist primarily of salaries, commissions, and other expenses relating to our selling,
general and administrative activities.

Research and development expenses-

Research and development expenses primarily related to personnel costs and depreciation of equipment relating to our research and
development activities.

Other income (expense)-

Other income (expense) consists primarily of foreign exchange gains or losses and gains or losses from marketable securities.

Effects of Our Recent Acquisition Activities on Our Financial Statements

As discussed under Item 4.A Information on the Company-History and Development of the Company, we have sought growth by
investing in, or acquiring companies with motors, drives and other related products and technologies. Depending on the circumstances, we acquire a majority interest or a substantial minority interest in the target companies. Our approach has been to
identify underperforming companies with advanced products and technologies. In the past years, we have acquired substantial interests in a number of major companies, several of which were public companies in Japan.

On April 27, 2007, we acquired a 51.7% share in Japan Servo Co., Ltd. (currently Nidec Servo Corporation (Nidec
Servo)). Nidec Servo has long been engaged in the manufacture and sale of small motors and motor applied products. In April, 2010, we and Nidec Servo entered into a share exchange agreement to make Nidec Servo our wholly owned subsidiary. The
share exchange transaction is expected to become effective on October 1, 2010, in accordance with a resolution adopted at an ordinary general meeting of Nidec Servo shareholders held on June 18, 2010.

On June 13, 2008, we acquired all of the voting rights of Shanghai Nidec Automotive Electric Motors Limited. In addition, on
August 1, 2008, we acquired an additional 3,500 new shares of Copal Yamada Corporation. We previously owned 3,000 shares prior to August 1, 2008. As a result, the number of shares we held in Copal Yamada Corporation increased to 68.4%.

On March 31, 2009, we disposed of all of the shares we held in Nidec Nemicon Corporation, a subsidiary. This disposition
did not have a material impact on our consolidated financial position, results of operations or liquidity.

In August 2009, to
enhance our profit from manufacturing and selling sintered-alloy fluid dynamic bearing units, we acquired all of the voting interests in two joint ventures, NTN-Nidec (Zhejiang) Corporation and NTN-Nidec (Thailand) Co., Ltd., held by our joint
venture partner, NTN Corporation in Japan. We and NTN Corporation established the two joint ventures in August 2002 and November 2005, respectively. Prior to our acquisition of the additional voting interests in August 2009, we held 40.0%, and NTN
Corporation held 60.0%, of the voting interests in each joint venture. Following the acquisition, these companies were renamed Nidec Bearing (Zhejiang) Corporation, and Nidec Bearing (Thailand) Co., Ltd, respectively.

In January 2010, to strengthen our position in the household motor market and to expand our business in Europe, we acquired the household
motor business of Appliances Components Companies S.p.A. in Italy through a share purchase transaction. The acquired business, which was renamed Nidec Sole Motor Corporation S.R.L. following the transaction, became our wholly owned subsidiary.

In February, 2010, to meet the increasing demand for hard disk spindle motors, we acquired 75.0% of the outstanding shares of
SC WADO Co., Ltd. in Thailand, which is a manufacturer of base plates, through a share transfer transaction. As a result of the transaction and a subsequent purchase of additional shares, we currently hold 90.0% of the outstanding shares of SC WADO.

Effects of Foreign Currency Fluctuations

A significant portion of our business is conducted in currencies other than the yen, most significantly, the U.S. dollar. Our business is
thus sensitive to fluctuations in foreign currency exchange rates, especially the yen-U.S. dollar exchange rate. As of March 31, 2008, 2009 and 2010, the exchange rate of the yen against the U.S. dollar was ¥100.19, ¥98.23 and
¥93.04 to the U.S. dollar, respectively.

##### Table of Contents

Our consolidated financial statements are subject to both translation risk and transaction
risk. Translation risk is the risk that our consolidated financial statements for a particular period or for a particular date are affected by changes in the prevailing exchange rates of the currencies in those countries in which we conduct business
against the Japanese yen. The translation effect, even if it is substantial, is a reporting consideration and does not reflect our underlying results of operations.

Transaction risk arises when the currency structure of our costs and liabilities deviates from the currency structure of our sales
proceeds and assets. A substantial portion of our overseas sales are made in U.S. dollars. While sales denominated in U.S. dollars are, to a significant extent, offset by U.S. dollar denominated costs, we generally have had a significant net long
U.S. dollar position. With respect to costs not denominated in U.S. dollars, we believe that we have been able to reduce the level of transaction risk to the extent that our overseas subsidiaries incur costs in currencies that generally follow the
U.S. dollar. Transaction risk remains for products sold in U.S. dollars to the extent that we must purchase parts for our products from Japan, the costs for which are denominated in yen.

Changes in the fair values of our foreign exchange forward contracts and changes in option prices under our foreign currency option
agreements are recognized as gains or losses on derivative instruments in our consolidated statement of income. For a more detailed discussion of these instruments, you should read Item 11 Quantitative and Qualitative Disclosure About
Market Risk and Note 21 Fair Value to our consolidated financial statements included in this annual report.

As a percentage of net sales, operating income increased from 8.5% for the year ended
March 31, 2009 to 13.3% for the year ended March 31, 2010.

Other Income (Expense)

Our other expenses decreased ¥1,405 million, or 29.6%, from ¥4,745 million for the fiscal year ended March 31, 2009
to ¥3,340 million for the fiscal year ended March 31, 2010. This decrease was mainly due to reductions in losses on marketable securities and foreign exchange loss, partially offset by a decrease in net interest income and a decrease
in dividend income.

We had gains from marketable securities in the amount of ¥52 million for the fiscal year ended
March 31, 2010, compared to losses on marketable securities in the amount of ¥1,305 million for the fiscal year ended March 31, 2009. This improvement was mainly due to a decrease in other-than-temporary losses on marketable
securities from ¥1,617 million for the fiscal year ended March 31, 2009 to ¥273 million for the fiscal year ended March 31, 2010.

Our foreign exchange loss decreased ¥715 million, or 19.4%, from ¥3,683 million for the fiscal year ended
March 31, 2009 to ¥2,968 million for the fiscal year ended March 31, 2010. This decrease was principally due to the appreciation in the value of the yen against relevant foreign currencies compared to the previous fiscal year. The
exchange rate of the yen against the U.S. dollar as of March 31, 2008, 2009 and 2010 was ¥100.19, ¥98.23 and ¥93.04, respectively.

As a result of the foregoing, our income from continuing operations before income taxes increased ¥27,732 million, or 58.7%, from
¥47,270 million for the fiscal year ended March 31, 2009 to ¥75,002 million for the fiscal year ended March 31, 2010.

Income Taxes

Our income
taxes increased ¥5,044 million, or 40.4%, from ¥12,475 million for the fiscal year ended March 31, 2009 to ¥17,519 million for the fiscal year ended March 31, 2010.

The effective income tax rate for the fiscal year ended March 31, 2010 was 23.4%, compared with the effective income tax rate of
26.4% for the fiscal year ended March 31, 2009. The lower effective income tax rate was primarily due to a net impact of a decrease in the impact on the effective tax rate of the valuation allowance and tax benefit in foreign subsidiaries.

For a detailed discussion of our income taxes, see Note 18 to our consolidated financial statements included elsewhere in
this annual report.

Equity in Net Loss of Affiliated Companies

Equity in net loss of affiliated companies decreased ¥3 million, or 6.3%, from ¥48 million for the fiscal year ended
March 31, 2009 to ¥45 million for the fiscal year ended March 31, 2010.

Our net sales decreased ¥113,558 million, or
15.7%, from ¥724,361 million for the year ended March 31, 2008 to ¥610,803 million for the year ended March 31, 2009. Net sales of all of our product categories, excluding machinery and other products, decreased. This
decrease was primarily due to the recent world-wide recession that resulted in a decrease in demand for our products and the yen appreciating against the U.S. dollar.

(Small precision motors)

Net sales of small precision motors decreased ¥71,609 million, or 18.6%, from ¥385,682 million for the year ended
March 31, 2008 to ¥314,073 million for the year ended March 31, 2009. Net sales of each product category included in small precision motors are as shown below.

Hard disk drives spindle motors

Net sales of our hard disk drives, or HDD, spindle motors decreased ¥41,813 million, or 18.7%, from ¥223,068 million for
the year ended March 31, 2008 to ¥181,255 million for the year ended March 31, 2009. Unit shipments of the spindle motors decreased 4.7%. Sales decreased largely due to a 12% yen appreciation against the U.S. dollar.

##### Table of Contents

Unit shipments of our spindle motors for 2.5-inch HDDs increased over 20% for the fiscal
year ended March 31, 2009 compared to the previous fiscal year. Net sales of spindle motors for 2.5-inch HDDs increased 10% to account for 46% of our total sales of spindle motors for HDDs, closing on to the 51% share of total sales represented
by spindle motors for 3.5-inch HDDs.

Net sales of HDD spindle motors accounted for 30.8% of total net sales for the year
ended March 31, 2008 and 29.7% of total net sales for the year ended March 31, 2009.

Other small precision brushless DC
motors

Net sales of our other small precision brushless DC motors decreased ¥19,172 million, or 20.8%, from
¥92,359 million for the year ended March 31, 2008 to ¥73,187 million for the year ended March 31, 2009. This decrease was primarily due to decreased customer demand caused by the economic slowdown.

Net sales of our other small precision brushless DC motors accounted for 12.8% of total net sales for the year ended March 31, 2008
and 12.0% of total net sales for the year ended March 31, 2009.

Brushless DC fans

Net sales of brushless DC fans decreased ¥9,180 million, or 19.7%, from ¥46,525 million for the year ended
March 31, 2008 to ¥37,345 million for the year ended March 31, 2009. This decrease was mainly due to decreased customer demand in the personal computer, or PC, industry.

Net sales of brushless DC fans accounted for 6.4% of total net sales for the year ended March 31, 2008 and 6.1% of total net sales
for the year ended March 31, 2009.

Other small precision motors

Net sales of other small precision motors decreased ¥1,444 million, or 6.1%, from ¥23,730 million for the year ended
March 31, 2008 to ¥22,286 million for the year ended March 31, 2009. This decrease was mainly due to decreases in sales by Nidec Sankyo, Nidec Servo and their subsidiaries.

Net sales of other small precision motors accounted for 3.3% of total net sales for the year ended March 31, 2008 and 3.6% of total
net sales for the year ended March 31, 2009.

(Mid-size motors)

Net sales of our mid-size motors decreased ¥19,221 million, or 19.9%, from ¥96,377 million for the year ended
March 31, 2008 to ¥77,156 million for the year ended March 31, 2009. This decrease was mainly due to a decrease in sales of mid-size motors for automobiles by Nidec Motors & Actuators, and a decrease in sales of mid-size
motors for home appliances by Nidec Shibaura, which were impacted by the economic slowdown.

Net sales of our mid-size motors
accounted for 13.3% of our total net sales for the year ended March 31, 2008 and 12.6% of total net sales for the year ended March 31, 2009.

(Machinery)

Net sales of our machinery increased ¥577 million, or 0.8%, from ¥68,858 million for the year ended March 31, 2008
to ¥69,435 million for the year ended March 31, 2009. This increase was primarily due to an increase in sales of liquid crystal display, or LCD, panel handling robots by Nidec Sankyo. The increase in sales of these robots reflected
improved demand and delayed adverse impacts of the economic recession as customers generally plan the capital investments for these types of products far in advance.

Net sales of our machinery accounted for 9.5% of our total net sales for the year ended March 31, 2008 and 11.4% of total net sales
for the year ended March 31, 2009.

(Electronic and optical components)

Net sales of our electronic and optical components decreased ¥23,344 million, or 16.0%, from ¥145,896 million for the
year ended March 31, 2008 to ¥122,552 million for the year ended March 31, 2009. This decrease was primarily due to decreases in sales of shutters for digital cameras and mobile phone cameras by Nidec Copal, electronic components
by Nidec Electronics and sales by Nidec Sankyos subsidiaries, all of which were impacted by the recent economic slowdown.

Net sales of our electronic and optical components accounted for 20.1% of our total net sales for the year ended March 31, 2008 and
2009.

(Others)

Net sales of our other products increased ¥39 million, or 0.1%, from ¥27,548 million for the year ended March 31,
2008 to ¥27,587 million for the year ended March 31, 2009.

Net sales of our other products accounted for 3.8%
of our total net sales for the year ended March 31, 2008 and 4.5% of total net sales for the year ended March 31, 2009.

Cost of
Products Sold

Our cost of products sold decreased ¥87,204 million, or 15.4%, from ¥567,679 million for
the year ended March 31, 2008 to ¥480,475 million for the year ended March 31, 2009. This decrease was primarily due to decreases in sales and productions.

As a percentage of net sales, cost of sales increased from 78.4% for the year ended March 31, 2008 to 78.7% for the year ended
March 31, 2009.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses increased ¥1,786 million, or 3.6%, from ¥49,702 million for the year
ended March 31, 2008 to ¥51,488 million for the year ended March 31, 2009. This increase reflected the fact that, for the fiscal year ended March 31, 2009, we recorded a smaller non-recurring gain and a smaller gain related
to fixed assets than we did for the year ended March 31, 2008. The decreases in such gains more than offset the decreases in personnel expenses and sales commissions for the fiscal year ended March 31, 2009.

As a percentage of net sales, selling, general and administrative expenses increased from 6.9% for the year ended March 31, 2008 to
8.4% for the year ended March 31, 2009.

Research and Development Expenses

Our research and development expenses decreased ¥2,758 million, or 9.3%, from ¥29,583 million for the year ended
March 31, 2008 to ¥26,825 million for the year ended March 31, 2009. This decrease was primarily due to our cost reduction measures in response to the recent world-wide recession, although research and development expenses
relating to mid-size motors for automobiles increased in response to increased demand for our new products for electric vehicles, or EV, and hybrid electric vehicles, or HEV.

As a percentage of net sales, research and development expenses increased from 4.1% for the year ended March 31, 2008 to 4.4% for
the year ended March 31, 2009.

Operating Income

As a result of the foregoing factors, our operating income decreased ¥25,382 million, or 32.8%, from ¥77,397 million for
the year ended March 31, 2008 to ¥52,015 million for the year ended March 31, 2009.

As a percentage of net
sales, operating income decreased from 10.7% for the year ended March 31, 2008 to 8.5% for the year ended March 31, 2009.

Other
Income (Expense)

Our other expenses decreased ¥8,563 million, or 64.3%, from ¥13,308 million for the
year ended March 31, 2008 to ¥4,745 million for the year ended March 31, 2009. This change was mainly due to a decrease in foreign exchange losses.

Our foreign exchange loss decreased ¥9,535 million, or 72.1%, from ¥13,218 million for the year ended March 31,
2008 to ¥3,683 million for the year ended March 31, 2009. This was principally due to appreciation in the value of the yen against relevant foreign currencies compared to the previous fiscal year. The exchange rate of the yen against
the U.S. dollar as of March 31, 2007, 2008 and 2009 was ¥118.05, ¥100.19 and ¥98.23, respectively.

We
incurred losses from marketable securities in the amount of ¥1,305 million for the year ended March 31, 2009, while we had gains from marketable securities in the amount of ¥454 million for year ended March 31, 2008. This
change was mainly due to an increase in the other-than-temporary losses on marketable securities as compared to the year ended March 31, 2008.

Income from Continuing Operations before Income Taxes

As a result of the foregoing, our income from continuing operations before income taxes decreased ¥16,819 million, or 26.2%, from
¥64,089 million for the year ended March 31, 2008 to ¥47,270 million for the year ended March 31, 2009.

Income
Taxes

Our income taxes decreased ¥3,383 million, or 21.3%, from ¥15,858 million for the year ended
March 31, 2008 to ¥12,475 million for the year ended March 31, 2009.

The effective income tax rate for the
year ended March 31, 2009 was higher compared to the effective income tax rate for the year ended March 31, 2008. The main reason of this increase was due to a net impact of an increase in the impact on the effective tax rate of the
valuation allowance, decrease in tax on undistributed earnings due to tax law changes and decrease in liabilities for unrecognized tax benefits for reductions for tax positions of prior years.

recorded equity in net income of affiliated companies in the amount of ¥39 million for the year ended March 31, 2008.

Income
from Continuing Operations

As a result of the foregoing, our income from continuing operations decreased
¥13,523 million, or 28.0%, from ¥48,270 million for the year ended March 31, 2008 to ¥34,747 million for the year ended March 31, 2009.

As a percentage of net sales, our income from continuing operations decreased from 6.7% for the year ended March 31, 2008 to 5.7%
for the year ended March 31, 2009.

Loss on Discontinued Operations

Our loss on discontinued operations increased ¥2,480 million, or 240.3%, from ¥1,032 million for the year ended
March 31, 2008 to ¥3,512 million for the year ended March 31, 2009.

We discontinued the optical pickup
unit business of Nidec Sankyo Corporation as of December 31, 2008 and the semiconductor manufacturing equipment business of Nidec Tosok Corporation as of September 30, 2009. For details, please see Note 25 to our consolidated financial
statements included elsewhere in this annual report.

Consolidated Net Income

As a result of the foregoing, our consolidated net income decreased ¥16,003 million, or 33.9%, from ¥47,238 million for
the year ended March 31, 2008 to ¥31,235 million for the year ended March 31, 2009.

Net Income Attributable to
Noncontrolling Interests

Net income (loss) attributable to noncontrolling interests decreased ¥3,200 million, or
52.6%, from ¥6,082 million for the year ended March 31, 2008 to ¥2,882 million for the year ended March 31, 2009. This decrease was primarily due to decreases in net income of group companies in which we hold
noncontrolling interests such as Nidec Servo Corporation, Nidec Copal Corporation and their respective subsidiaries, resulting from reduced demand for their products caused by the world wide recession.

Net Income Attributable to Nidec Corporation

As a result of the foregoing, our net income decreased ¥12,803 million, or 31.1%, from ¥41,156 million for the year
ended March 31, 2008 to ¥28,353 million for the year ended March 31, 2009.

Segment Information

Based on the applicable criteria set forth in ASC 280, Segment Reporting (formerly, SFAS No.131, Disclosures about
Segments of an Enterprise and Related Information.), we have 14 reportable operating segments on which we report in our consolidated financial statements. These reportable operating segments are primarily based on legal entities. As described
below, one of the reportable segments is NCJ, while the others are NCJs 13 consolidated subsidiaries: NET, NCC, NCD, NCS, NCH, NCF, NSNK, NCPL, NTSC, NCEL, NSRV, NTMC and NMA. For the information required by ASC280, see Note 26 to our
consolidated financial statements included elsewhere in this annual report.

We have changed our segment reporting in line
with the changes we made in our management decision-making process during the year ended March 31, 2010. In August 2009, we integrated the operations of Nidec Electronics GmbH into those of Nidec Motors & Actuators (Germany) GmbH
within the NMA segment, and also integrated the operations in China previously included within the NCD segment, other than the DC motors and fans operations, and the in-car motors operations previously included in the All Others segment into the NMA
segment, to enhance its automobiles motors businesses. In October 2009, we reorganized the operations of Nidec Shibaura Corporation (NSBC) and those of Nidec Power Motor Corporation into Nidec Techno Motor Holdings Corporation
(NTMC) to enhance its mid-size motors businesses. As a result, we have newly created an NTMC segment consisting of operations relating to mid-size motors for home appliances and industrial use, which were previously included in the NSBC
segment and the All Others segment.

The NSCJ and NNSN segments are no longer reported as reportable segments and are included
in the All Other segment in the current period due to their immateriality.

All prior period information has been reclassified
in accordance with the current period presentation.

The NCJ segment comprises Nidec Corporation in Japan, which primarily
produces and sells hard disk drive motors, DC motors, fans, and mid-size motors.

The NET segment comprises Nidec Electronics
(Thailand) Co., Ltd. and Nidec Precision (Thailand) Co., Ltd., subsidiaries in Thailand, which primarily produce and sell hard disk drive motors.

comprises Nidec Tosok Corporation, a subsidiary in Japan, which primarily produces and sells automotive parts and machinery.

The NCEL segment comprises Nidec Copal Electronics Corporation, a subsidiary in Japan, which primarily produces and sells electronic
parts.

The NSRV segment comprises Nidec Servo Corporation in Japan, which primarily produces and sells DC motors, fans and
other small precision motors.

The NTMC segment comprises Nidec Techno Motor Holdings Corporation, a subsidiary in Japan, and
its subsidiaries in Japan, China and Thailand, which primarily produce and sell mid-size motors.

The NMA segment comprises
Nidec Motors & Actuators (Germany) GmbH, other subsidiaries in Europe and North America, and other manufacturing subsidiaries in China, which primarily produce and sell automotive motors.

The All Others segment comprises subsidiaries that are operating segments but not designated as reportable segments due to materiality.

In accordance with ASC 205-20, Presentation of Financial Statements-Discontinued Operations (formerly SFAS
No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets), amounts in the segment information do not reflect discontinued operations, and previous fiscal years segment information has been reclassified.

We evaluate our performance based on segmental profit and loss, which is derived from segmental sales and operating revenues
less operating expenses. Segmental income or loss is determined using the accounting principles in the segments country of domicile. NCJ, NSNK, NCPL, NTSC, NCEL, NSRVs operating income or loss is determined using Japanese GAAP. NET
applies Thai accounting principles. NCC and NCD apply Chinese accounting principles. NCS applies Singaporean accounting principles. NCH applies Hong Kong accounting principles. NCF applies Philippine accounting principles. NTMC mainly applies
Japanese GAAP, and NMA applies mainly International Financial Reporting Standards (IFRS). Therefore, our segmental data have not been prepared under U.S. GAAP on a basis that is consistent with the consolidated financial statements or on any other
single basis that is consistent between segments. While there are several differences between U.S. GAAP and the underlying accounting bases used by management, the principal differences that affect segmental operating income or loss are accounting
for pension and severance costs and for leases. Management believes that the monthly segmental information is available on a timely basis and that it is sufficiently accurate at the segment income or loss level for managements purposes.

The first of the following two tables shows net sales from external customers and other operating segments by reportable
operating segment for the years ended March 31, 2008, 2009 and 2010. The second table shows operating income or loss by reportable operating segment, which includes inter segment revenues, for the years ended March 31, 2008, 2009 and 2010:

2009 to ¥47,130 million for the fiscal year ended March 31, 2010. The main reason for this decrease was a decrease in demand for LCD panel handling robots. Operating income of NSNK decreased ¥1,608 million, or 35.9%, from
¥4,473 million for the fiscal year ended March 31, 2009 to ¥2,865 million for the fiscal year ended March 31, 2010. The reason for this decrease was the decrease in sales.

Net sales of NSNK increased ¥3,685 million, or 6.3%, from ¥58,351 million for the fiscal year ended March 31, 2008
to ¥62,036 million for the fiscal year ended March 31, 2009 due to an increase in sales of LCD panel handling robots, which more than offset the adverse impact of exchange rate fluctuations. However, operating income of NSNK decreased
¥135 million, or 2.9%, from ¥4,608 million for the fiscal year ended March 31, 2008 to ¥4,473 million for the fiscal year ended March 31, 2009. The major reason for this decrease was a decrease in profitability
caused by a decrease in sales of products other than LCD panel handling robots, such as card readers with a higher margin.

Net sales of NCPL decreased ¥10,436 million, or 17.4%, from ¥59,817 million for the fiscal year ended March 31,
2009 to ¥49,381 million for the fiscal year ended March 31, 2010. This was due primarily to a decrease in sales of camera shutters for mobile phones and system equipment such as industrial robots. Operating income of NCPL decreased
¥582 million, or 27.7%, from ¥2,102 million for the fiscal year ended March 31, 2009 to ¥1,520 million for the fiscal year ended March 31, 2010. This was due primarily to the decrease in sales.

Net sales of NCPL decreased ¥10,556 million, or 15.0%, from ¥70,373 million for the fiscal year ended March 31,
2008 to ¥59,817 million for the fiscal year ended March 31, 2009. This was due primarily to a rapid decrease in demand for shutters for digital cameras and camera shutters for mobile phones. Operating income of NCPL decreased
¥1,313 million, or 38.4%, from ¥3,415 million for the fiscal year ended March 31, 2008 to ¥2,102 million for the fiscal year ended March 31, 2009. This was due primarily to the decrease in sales of shutters for
digital cameras and camera shutters for mobile phones.

Net sales of NTSC increased ¥2,634 million, or 12.7%, from
¥20,694 million for the fiscal year ended March 31, 2009 to ¥23,328 million for the fiscal year ended March 31, 2010. This was due primarily to an increase in demand for automotive parts, which more than offset a decrease
in sales of measuring equipment. Operating income increased ¥598 million, or 55.0%, from ¥1,088 million for the fiscal year ended March 31, 2009 to ¥1,686 million for the fiscal year ended March 31, 2010. This
was due to a reduction in selling, general and administrative expenses and enhanced efficiency in manufacturing processes, in addition to the expansion in demand.

Net sales of NTSC decreased ¥427 million, or 2.0%, from ¥21,121 million for the fiscal year ended March 31, 2008
to ¥20,694 million for the fiscal year ended March 31, 2009. This was due primarily to a decrease in sales of measuring equipment resulting from the world-wide recession. Operating income decreased ¥213 million, or 16.4%, from
¥1,301 million for the fiscal year ended March 31, 2008 to ¥1,088 million for the fiscal year ended March 31, 2009. This was due primarily to the decrease in sales.

for the fiscal year ended March 31, 2009 to ¥21,957 million for the fiscal year ended March 31, 2010. This was due primarily to a decrease in sales of electronic components such as switches. Operating income decreased
¥277 million, or 13.5%, from ¥2,046 million for the fiscal year ended March 31, 2009 to ¥1,769 million for the fiscal year ended March 31, 2010 due primarily to the decrease in sales.

Net sales of NCEL decreased ¥1,060 million, or 4.0%, from ¥26,569 million for the fiscal year ended March 31, 2008
to ¥25,509 million for the fiscal year ended March 31, 2009. This decrease was due primarily to a decrease in sales of electronic components. Operating income decreased ¥1,585 million, or 43.7%, from ¥3,631 million
for the fiscal year ended March 31, 2008 to ¥2,046 million for the fiscal year ended March 31, 2009 due primarily to the decrease in sales.

Net sales of NSRV decreased ¥4,470 million, or 18.2%, from ¥24,537 million for the fiscal year ended March 31,
2009 to ¥20,067 million for the fiscal year ended March 31, 2010. This was due primarily to a decrease in demand for small precision motors, such as stepping motors and fans. NSRV had operating income of ¥792 million for the fiscal
year ended march 31, 2010 compared to an operating loss of ¥225 million for the fiscal year ended March 31, 2009. In spite of a decrease in sales, operating income increased due to a temporary salary cut, cost reduction resulting in
part from improved material procurement management and an increase in royalty from subsidiaries.

Net sales of NSRV decreased
¥4,390 million, or 15.2%, from ¥28,927 million for the fiscal year ended March 31, 2008 to ¥24,537 million for the year ended March 31, 2009. This was due primarily to a rapid decrease in the demand for small
precision motors resulting from the world wide-recession. NSRV had an operating loss of ¥225 million for the fiscal year ended March 31 2009 compared to operating income of ¥372 million for the fiscal year ended March 31,
2008. This was due primarily to the rapid decrease in sales.

Net sales of NTMC decreased ¥6,328 million, or 15.0%,
from ¥42,175 million for the fiscal year ended March 31, 2009 to ¥35,847 million for the fiscal year ended March 31, 2010. This was primarily due to a decrease in demand for industrial motors and home appliances motors.
The impact of decreased demand was more significant on the industrial motor business because of sluggish corporate spending. Operating income increased ¥507 million, or 38.7%, from ¥1,309 million for the fiscal year ended
March 31, 2009 to ¥1,816 million for the fiscal year ended March 31, 2010. This increase was primarily due to improved product mix and reduced costs deriving from improved material procurement management.

2008 to ¥42,175 million for the fiscal year ended March 31, 2009. This was due primarily to a decrease in demand for home appliances motors resulting from the world-wide recession. Operating income decreased ¥912 million, or
41.1%, from ¥2,221 million for the fiscal year ended March 31, 2008 to ¥1,309 million for the fiscal year ended March 31, 2009. This decrease was due primarily to the decrease in sales and an increase in production costs.

Net sales of NMA decreased ¥278 million or 0.7%, from ¥41,896 million for the fiscal year ended
March 31, 2009 to ¥41,618 million for the fiscal year ended March 31, 2010 due primarily to a decrease in the demand for automotive motors. NMA had operating income of ¥553 million for the fiscal year ended March 31, 2010
compared to an operating loss of ¥407 million for the fiscal year ended March 31, 2009. In spite of the decrease in sales, operating income increased due to reduced costs deriving from improved material procurement management with

for the fiscal year ended March 31, 2008 to ¥41,896 million for the fiscal year ended March 31, 2009 due primarily to a rapid decrease in the demand for automotive motors resulting from the world-wide recession. NMA had an
operating loss of ¥407 million for the fiscal year ended March 31, 2009 compared to operating income of ¥1,174 million for the fiscal year ended March 31, 2008. This was due primarily to the decrease in sales, despite a
reduction in fixed costs.

Within the All Others segment, net sales decreased ¥344 million, or 0.1% from
¥282,626 million for the fiscal year ended March 31, 2009 to ¥282,282 million for the fiscal year ended March 31, 2010. This was due primarily to a decrease in sales of machinery by subsidiaries belong to the segment,
which more than offset the addition of newly consolidated subsidiaries to the segment. Operating income increased ¥9,054 million, or 74.2% from ¥12,205 million for the fiscal year ended March 31, 2009 to
¥21,259 million for the fiscal year ended March 31, 2010. This was due primarily to an increase in operating income of subsidiaries relating to small precision motors and electronic and optical components.

ended March 31, 2008 to ¥282,626 million for the fiscal year ended March 31, 2009. This was due primarily to a decrease in demand for many of the products of subsidiaries belonging to this segment resulting form the world-wide
recession. Operating income decreased ¥9,584 million, or 44.0% from ¥21,789 million for the fiscal year ended March 31, 2008 to ¥12,205 million for the fiscal year ended March 31, 2009. This was due primarily to
the decrease in sales.

Accounting Changes

As of September 15, 2009, we adopted the FASB Accounting Standards Codification (ASC) 105, Generally Accepted Accounting
Principles (formerly, Statement of Financial Accounting Standards (SFAS) No. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principlesa replacement of FASB Statement
No. 162). ASC 105 replaces SFAS No. 162 the Hierarchy of Generally Accepted Accounting Principles and establishes the FASB Accounting Standards Codification as the single source of authoritative nongovernmental U.S.
Generally Accepted Accounting Principles (other than guidance issued by the SEC). The adoption of ASC 105 had no impact on our consolidated financial position, results of operations or liquidity.

As of April 1, 2009, we adopted ASC 820, Fair Value Measurements and Disclosures (formerly, SFAS No. 157,
Fair Value Measurements) for certain nonfinancial assets and liabilities. FASB Staff Position (FSP) No. FAS 157-2, Effective Date of FASB Statement No. 157 delays the effective date of ASC 820 for one year for
nonfinancial assets and liabilities. The adoption of ASC 820 did not have a material impact on our consolidated financial position, results of operations or liquidity.

As of April 1, 2009, we adopted ASC 805, Business Combinations (formerly, SFAS No. 141 (revised 2007),
Business Combinations). ASC 805 requires that assets acquired, liabilities assumed, contractual contingencies, and contingent consideration be measured at fair value as of the acquisition date, that acquisition-related costs be expensed
as incurred, that restructuring costs generally be expensed in periods subsequent to the acquisition date, and the changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period
impact income tax expense. The adoption of ASC 805 did not have a material impact on our consolidated financial position, results of operations or liquidity since we did not acquire any material businesses for the year ended March 31, 2010. Any
future impact, however, will depend on the number, size, and nature of any business combination transactions that we may complete.

As of April 1, 2009, we adopted ASC 810, Consolidation (formerly, SFAS
No. 160, Noncontrolling Interests in Consolidated Financial Statements  an amendment of ARB No. 51). ASC 810 recharacterizes minority interests in a subsidiary as non-controlling interests and requires the presentation of
noncontrolling interests as equity in consolidated balance sheets, and separate identification and presentation in consolidated statements of income of net income attributable to the entity and the noncontrolling interest. ASC 810 also requires all
transactions for changes in a parents ownership interest in a subsidiary that do not result in the subsidiary ceasing to be a subsidiary to be recognized as equity transactions. Upon adoption, noncontrolling interests, which were previously
referred to as minority interests and classified in the mezzanine section between liabilities and equity on the consolidated balance sheets, are now included as a separate component of total equity. Consolidated net income on the consolidated
statements of income now includes the net income (loss) attributable to noncontrolling interests. In addition, payments for additional investments in subsidiaries, which were previously classified in the cash flows from investing activities on the
consolidated statements of cash flows, are now included in cash flows from financing activities. Prior period amounts were reclassified to conform to the current period presentation.

As of June 15, 2009, we adopted ASC 855, Subsequent Events (formerly, SFAS No. 165, Subsequent Events).
ASC 855 establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. The adoption of ASC 855 did not have a material impact
on our consolidated financial position, results of operations or liquidity.

As of December 15, 2009, we adopted ASC 715,
Compensation  Retirement Benefits, (formerly, FSP No. FAS 132(R)-1, Employers Disclosures about Postretirement Benefit Plan Assets). ASC 715 provides guidance on employers disclosures of a defined benefit
pension or other postretirement plan. Specifically, employers are required to disclose information about fair value measurements of plan assets. The adoption of ASC 715 did not have a material impact on our consolidated financial position, results
of operations and liquidity.

Recent Accounting Pronouncements to Be Adopted in Future Periods

In December 2009, the FASB issued Accounting Standards Update (ASU) No. 2009-16, Accounting for Transfers of Financial
Assets. This accounting standard codified SFAS No.166, Accounting for Transfers of Financial Assets  an amendment of FASB Statement No. 140. ASU 2009-16 requires more information about transfers of financial assets,
including securitization transactions, and where companies have continuing exposure to the risks related to transferred financial assets. ASU 2009-16 also eliminates the concept of a qualifying special-purpose entity, changes the
requirements for derecognizing financial assets. ASU 2009-16 is effective as of the beginning of each reporting entitys first annual reporting period that begins after November 15, 2009, for interim periods within that first annual
reporting period, and for interim and annual reporting periods thereafter. The adoption of ASU 2009-16 is not expected to have a material impact on our consolidated financial position, results of operations and liquidity.

In December 2009, the FASB issued ASU No. 2009-17, Improvements to Financial Reporting by Enterprises Involved with Variable
Interest Entities. This accounting standard codified SFAS No. 167, Amendments to FASB Interpretation No. 46(R). ASU 2009-17 requires an enterprise to perform an analysis to identify the primary beneficiary of all variable
interest entities and also requires ongoing reassessments of whether an enterprise is the primary beneficiary of all variable interest entities. ASU 2009-17 is effective as of the beginning of each reporting entitys first annual reporting
period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. The adoption of ASU 2009-17 is not expected to have a material impact on our
consolidated financial position, results of operations and liquidity.

Application of Critical Accounting Policies

Nidec and its subsidiaries in Japan maintain their records and prepare their financial statements in accordance with accounting principles
generally accepted in Japan, and its foreign subsidiaries in conformity with those of their countries of domicile. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform U.S.
GAAP. The preparation of these financial statements requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of financial statements and the reported amounts of revenues and
expenses during the periods presented. Actual results may differ from these estimates, judgments and assumptions.

An
accounting estimate in our financial statements is a critical accounting estimate if it requires us to make assumptions about matters that are highly uncertain at the time the accounting estimate is made, and either different estimates that we
reasonably could have used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, would have a material impact on the presentation of our financial condition, changes in financial
condition or results of operations. We have identified the following critical accounting policies with respect to our financial presentation.

Inventories

Our
inventories, which consist primarily of finished products such as HDD spindle motors, are stated at the lower of cost or market value. Cost is determined principally using the weighted average cost method and the market value is mainly based on net
realizable value less direct sales costs. These products are exposed to frequent innovation, the introduction of new products to the market and short product life cycles due to rapid technological advances and model changes. We periodically assess
the market value of our inventory, based on sales trends and forecasts and technological changes and write off inventories with no movement for one year or when it is apparent that there is no possibility of future sales or usage. We may have to
recognize large amounts of inventory write-offs as a result of an unexpected decline in market conditions, changes in demand or our product line.

Other-than-temporary Losses on Marketable Securities

We review the market value of our marketable securities at the end of each fiscal quarter. Our marketable securities consist of
available-for-sale securities and held-to-maturity securities. Other-than-temporary losses on individual marketable securities are charged to income in the period as incurred. Losses on available-for-sale securities are classified as
other-than-temporary based on the length of time and the extent to which the fair value has been less than the carrying amount. Our management employs a systematic methodology to assess the recoverability of such investments by reviewing the
financial position of underlying companies and prevailing market conditions in which these companies operate to determine if our investment in each of these companies is impaired and whether the impairment is other-than-temporary. Held-to-maturity
securities are recorded at amortized cost and adjusted for the amortization or accretion of premiums or discounts.

We believe
that the accounting estimate related to investment impairment is a critical accounting policy because:



| |  |  | it is highly susceptible to change from period to period because it requires our management to make assumptions about future financial condition and
cash flows of investees; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the impact that recognizing an impairment would have on the total assets reported on our balance sheet as well as our operating income would be
material.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------

As of March 31, 2010, the estimated fair value of our marketable securities was ¥16,764
million. We recorded a gain from marketable securities in the amount of ¥52 million for the year ended March 31, 2010.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts based on the historical rate of credit losses experienced. We additionally provide
allowances for specific customer accounts deemed uncollectible. Management assesses the need for specific allowances based on changes in the customers financial condition and length of time the account has remained overdue. As our customer
base is highly concentrated, the nonfulfillment or delay in payment caused by even one of our major customers may require us to record a significant additional allowance. For the year ended March 31, 2010, sales to our six largest customers
represented approximately 41% of our net sales. Our accounts receivable are likewise concentrated. At March 31, 2010, six customers represented ¥61,629 million, or 41%, of our gross accounts receivable. In addition, during economic
downturns, a certain number of our customers may have difficulty with their cash flows.

Although we believe that we can make
reliable estimates for doubtful accounts, customer concentrations as well as overall economic conditions may affect our ability to accurately estimate the allowance for doubtful accounts. Our allowance for doubtful accounts amounted to
¥398 million as of March 31, 2010. Our trade notes and accounts receivable balance was ¥162,398 million, net of allowance for doubtful accounts, as of March 31, 2010.

The following table shows the provision for doubtful accounts, net of reversal.

Deferred Tax Assets

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the
jurisdictions in which we operate. This process requires us to estimate our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting
purposes. These differences resulted in deferred tax assets and liabilities, which were included within our consolidated balance sheet. As of March 31, 2010, we had deferred tax assets in the amount of ¥29,645 million. We must then assess
the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase
this allowance in a period, we must include an expense within the tax provision in our income statement.

##### Table of Contents

Significant management judgment is required in determining our provision for income taxes,
our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We have recorded a valuation allowance of ¥7,606 million as of March 31, 2010, due to uncertainties related to our
ability to utilize some of our deferred tax assets, primarily consisting of certain net operating losses carried forward for tax purposes incurred by our subsidiaries. Our determination to record valuation allowances is based on a history of
unprofitable periods by the subsidiaries and their estimated future profitability. In the event that actual results differ from these estimates or we adjust these estimates in future periods, we may need to establish an additional valuation
allowance which could have an adverse effect on our financial position and results of operations.

Impairment of Long-lived Assets

Long-lived assets consist primarily of property, plant and equipment, comprising approximately 29.1% of our total assets as of
March 31, 2010, and other intangible assets. We carefully monitor the appropriateness of the estimated useful lives of these assets. Since the fiscal year ended March 31, 2003, the first year we adopted testing for impairment of long-lived
assets under ASC 360 Property, Plant and Equipment (formerly, SFAS No.144, Accounting for the impairment or disposal of Long-Lived Assets), whenever events or changes in circumstances indicate that the carrying amounts of
these asset groups may not be recoverable, we have reviewed the respective asset groups for impairment. An impairment loss is recognized when the carrying amount of an asset group exceeds the estimated undiscounted future cash flows of the group. We
review idle assets for possible impairment based on their condition or based on the probability of future use. Changes in technology, market demand, our planned product mix, or in our intended use of these assets, may cause the estimated period of
use or the value of these assets to change. In addition, changes in general industry conditions such as increased competition could cause the value of a certain amount of these assets to change. Estimates and assumptions used in both estimating the
useful life and evaluating potential impairment issues require a significant amount of judgment. As such, our judgment as to the recoverability of capitalized amounts and the amount of any impairment will be significantly impacted by such factors.

Acquisitions

In recent years, we have made a number of significant business acquisitions, which had been accounted for using the purchase method of
accounting until the fiscal year ended March 31, 2009. As of April 1, 2009, NIDEC adopted ASC 805, Business Combinations (formerly SFAS No. 141 (revised 2007), Business Combinations). ASC 805 requires that
business acquisitions are accounted for using the acquisition method of accounting. Application of the purchase method and the acquisition method requires our management to make complex judgments about the measurement of fair value of the net assets
we acquire and estimation of the related useful lives. The determinations of fair value of assets and liabilities are primarily based on factors such as cash flow analysis and quoted market prices among others. We also obtained independent
appraisers reports for significant purchases.

Valuation of Goodwill

Under ASC 350 Intangibles - Goodwill and Other (formerly SFAS No.142 Goodwill and Other Intangible Assets),
goodwill acquired in business combinations is not amortized but tested annually for impairment. We test for impairment at the reporting unit level on January 1st of each year. In addition, we test for impairment between annual tests if an event
occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Factors we consider important which could trigger an impairment review include the following:



| |  |  | significant underperformance relative to expected historical or projected future operating results;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
| | - |  | -------------------------------------------------------------------------------------------------------------

| |  |  | significant negative industry or economic trends;
| | - |  | -------------------------------------------------



| |  |  | significant decline in the stock price of the acquired entity for a sustained period; and
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | market capitalization of the acquired entity relative to its net book value.
| | - |  | ----------------------------------------------------------------------------

This test is a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair
value of the reporting unit with its carrying amount, including goodwill. If the fair value, which is based on discounted future cash flows, exceeds the carrying amount, goodwill is not considered impaired. If the carrying amount exceeds the fair
value, the second step must be performed to measure the amount of the impairment loss, if any. The second step compares the implied fair value of the reporting units goodwill with the carrying amount of that goodwill. In order to evaluate the
sensitivity of the fair value calculations on the impairment analysis, we apply a hypothetical decrease to the fair value of each reporting unit. Also, among the reporting units, when testing the goodwill for impairment allocated to our listed
subsidiaries, consideration was given to each listed subsidiarys carrying amount and its market capitalization based on a reasonable control premium.

When we determine that the carrying value of goodwill and other intangibles may not be recoverable, based upon the existence of one or
more of the above indicators of impairment, we measure any impairment based on a projected discounted cash flow determined by our management to be commensurate with the risk inherent in our current business model. Changes in the projected discounted
cash flow could negatively affect the valuations. Goodwill amounted to ¥72,231 million as of March 31, 2010.

Pension
Plans

We account for our defined benefit pension plans based on actuarial valuations. For periodic pension
calculation, we are required to assume some components, which include expected return on plan assets, discount rate, rate of increase in compensation levels and average remaining years of service. We use long-term historical actual return
information and estimated future long-term investment returns by reference to external sources to develop our expected rate of return on plan assets. The discount rate is assumed based on the rates available on high-quality fixed-income debt
instruments (rated AA by a recognized rating agency) for which the timing and amount of cash inflows approximates the estimated outflows of the defined benefit plan. We assume a rate of increase in compensation levels and average remaining years of
service based on our historical data. Changes in these assumptions will have an impact on our net periodic pension cost.

The
following table shows the sensitivity to a change in discount rates and the expected rate of return on plan assets, holding all other assumptions constant.

Income Taxes

We adopted FASB Accounting Standards Codification (ASC), 740 Income Taxes (formerly FASB Interpretation No.48,
Accounting for Uncertainty in Income Taxes  an interpretation of FASB Statement No.109,) on April 1, 2007. We consider many factors when evaluating and estimating income tax uncertainties. These factors include an evaluation
of the technical merits of the tax positions as well as the amounts and probabilities of the outcomes that could be realized upon settlement. The actual resolutions of those uncertainties will inevitably differ from those estimates, and such
differences may be material to the financial statements.

Revenue recognition -

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable
and collectibility is reasonably assumed. For small precision motors, mid-size motors and electronic and optical components, these criteria are generally met at the time a product is delivered to the customers site which is the time the
customer has taken title to the product and the risk and rewards of ownership have been substantively transferred. These conditions are met at the time of delivery to customers in domestic sales (FOB destination) and at the time of shipment for
export sales (FOB shipping point). Revenue for machinery sales is recognized upon receipt of final customer acceptance. At the time the related revenue is recognized, we make provisions for estimated product returns.

B. Liquidity and Capital Resources.

As part of our efforts to enhance liquidity, we placed a particular emphasis on efficient use of capital and better management of foreign
exchange risk during the year ended March 31, 2010. The details are as follows:

An effective use of our cash management
system, which have been shared among our domestic subsidiaries since April 2006, served to increase excess cash made available by our subsidiaries by ¥6,361 million compared to the previous fiscal year, contributing to a reduction in our
total interest-bearing debt.

We expanded our risk mitigation initiatives, including centralized management of foreign
exchange risk, to management of risks associated with exchange rate fluctuations between multiple local currencies. Surplus U.S. dollars owned by our subsidiaries in China were being converted into and held in the form of Chinese yuan time deposit
in preparation for possible Chinese currency revaluation. As of March 31, 2010, our cash and cash equivalents of Chinese yuan were approximately RMB 1,000 million.

Our principal capital needs include (1) purchases of property, plant and equipment and other assets, (2) research and
development activities, (3) investment in subsidiaries, (4) mergers and acquisitions, (5) repayment of short-term borrowings, (6) purchases of raw materials, and (7) employees salaries, wages and other payroll costs.

Investments for the purchase of property, plant, equipment and other assets totaled approximately ¥36,608 million
for the year ended March 31, 2010, and are expected to amount to approximately ¥44,694 million for the year ending March 31, 2011. Outstanding commitments for the purchase of property, plant and equipment and other assets amounted
to approximately ¥2,115 million as of March 31, 2010.

Research and development expenses were
¥24,713 million for the fiscal year ended March 31, 2010, and are expected to reach approximately ¥33,000 million for the fiscal year ending March 31, 2011.

We continue to seek opportunities for additional investments in our subsidiaries and will review opportunities to acquire other
companies.

##### Table of Contents

We expect to cover the foregoing capital needs with cash provided by our operating and
financing activities.

A substantial portion of our unsecured funding is raised by the parent company (Nidec Corporation), and
is then lent to its subsidiaries to meet their respective capital requirements. Under this subsidiary funding policy, we seek to lower the financing cost, maintain sufficient line of credit, and ensure agile funding for our group companies.

As a precaution for possible funding risk resulting from the global credit crunch, we used short-term borrowings to fund
emergency cash reserves of ¥100,000 million in the year ended March 31, 2010. The level of borrowing has since been reduced, reflecting our improving perception of the overall financial environment. As of March 31, 2010, our total
short-term borrowings were ¥115,467 million.

We also consider extending our funding options to direct financing in order
to enhance our financial agility in mergers and acquisitions, research and development activities and facility investments.

We believe that these funding sources will sufficiently meet our capital requirements for the current fiscal year.

Assets, liabilities and shareholders equity

Our total assets decreased ¥10,093 million from ¥702,884 million to ¥692,791 million as of March 31, 2010.
This was mainly due to a decrease in cash and cash equivalents of ¥77,657 million, as mentioned under Cash Flows below. On the other hand, trade accounts receivable increased ¥39,882 million due primarily to a recovery
in net sales. In addition, property, plant and equipment increased ¥11,622 million due primarily to the facilities constructions and additional facilities as a result of acquisitions of newly consolidated subsidiaries.

Our total liabilities decreased ¥53,937 million from ¥345,197 million as of March 31, 2009 to
¥291,260 million as of March 31, 2010. This was mainly due to a decrease in short-term borrowings of ¥105,875 million owing to repayment of borrowings obtained for our emergency cash reserve purposes. On the other hand, trade
notes and accounts payable increased ¥38,745 million due primarily to an increase in purchases reflecting the recent gradual recovery in sales.

Our working capital, defined as current assets less current liabilities, increased ¥28,345 million from ¥84,273 million
as of March 31, 2009 to ¥112,618 million as of March 31, 2010.

Our receivable turnover ratio is calculated
by dividing net sales for the fiscal year by the fiscal year-end trade notes and accounts receivable balance. Our receivable turnover ratio was 3.6 for the year ended March 31, 2010, compared to 5.0 for the year ended March 31, 2009. The
inventory turnover ratio is calculated by dividing cost of products sold for the year ended March 31 by the year-end inventory balance. Our inventory turnover ratio was 6.3 for the year ended March 31, 2010, compared to 8.4 for the year
ended March 31, 2009.

Net sales for the year ended March 31, 2010 decreased compared to the year ended
March 31, 2009 due to the global recession which began in the second half of the year ended March 31, 2009. In the second half of the year ended March 31, 2010, the global economy saw signs of a slow recovery from the global
recession. As a result, accounts receivable and inventories as of March 31, 2010 increased compared to March 31, 2009.

##### Table of Contents

Our total shareholders equity increased ¥43,161 million from
¥297,148 million as of March 31, 2009 to ¥340,309 million as of March 31, 2010. The increase of ¥43,161 million was primarily due to retained earnings of ¥44,300 million. As a result, the ratio of
stockholders equity to total assets increased 6.8 percentage points from 42.3% as of March 31, 2009 to 49.1% as of March 31, 2010.

Cash Flows

As of
April 1, 2009, we adopted ASC 810, Consolidation. Amounts for prior periods have been reclassified to conform to the current period presentation.

Net cash provided by operating activities increased ¥23,849 million from ¥66,231 million for the year ended
March 31, 2009 to ¥90,080 million for the year ended March 31, 2010. The increased cash inflows in operating activities were due primarily to an increases in consolidated net income ¥24,916 million.

For the year ended March 31, 2010, we had ¥90,080 million of cash inflows mainly due to consolidated net income of
¥56,151 million. On the other hand, we had a decrease in operating assets and liabilities of ¥5,185 million which consisted of an increase in operating assets of ¥40,979 million and an increase in operating liabilities of
¥35,794 million owing to sales recovery.

For the year ended March 31, 2009, we had ¥66,231 million of
cash inflows mainly due to consolidated net income of ¥31,235 million. On the other hand, we had a decrease in operating assets and liabilities of ¥821 million which consisted of a decrease in operating assets of
¥49,279 million and a decrease in operating liabilities of ¥50,100 million owing to lower sales due to the global recession.

Net cash provided by operating activities decreased ¥28,585 million from ¥94,816 million for the year ended
March 31, 2008 to ¥66,231 million for the year ended March 31, 2009. Amid the global economic crisis, the decreased cash inflows from operating activities were due primarily to a decrease in consolidated net income of
¥16,003 million and a decrease in foreign currency adjustments of ¥6,214 million. On the other hand, a ¥2,410 million increase in changes in operating assets and liabilities resulted from a decrease in net sales. The
¥2,410 million consisted of a decrease in operating assets of ¥54,828 million and a decrease in notes and accounts payable of ¥52,418 million.

For the year ended March 31, 2009, we had ¥66,231 million of cash inflows mainly due to consolidated net income of

¥50,100 million owing to lower sales due to the global recession.

For the year ended March 31, 2008,
¥94,816 million of cash inflows was mainly due to consolidated net income of ¥47,238 million.

Net cash used in
investing activities decreased ¥2,859 million from ¥43,373 million for the year ended March 31, 2009 to ¥40,514 million for the year ended March 31, 2010. The decreased cash outflows were due primarily to a
decrease in purchases of marketable securities ¥3,599 million and a decrease in additions to property, plant and equipment of ¥1,893 million, partially offset by an increase in acquisitions of business of ¥3,640 million.

For the year ended March 31, 2010, ¥40,514 million of cash outflows was mainly due to additions to property,
plant and equipments of ¥36,608 million for constructions of additional plant, and acquisitions of business, net of cash acquired of ¥4,396 million.

For the year ended March 31, 2009, ¥43,373 million of cash outflows was mainly due to additions to property, plant and
equipments of ¥38,501 million and purchases of marketable securities of ¥3,609 million.

Net cash used in investing activities increased ¥7,692 million from
¥35,681 million for the year ended March 31, 2008 to ¥43,373 million for the year ended March 31, 2009. The increased cash outflows in investing activities were due primarily to an increase in additions to property, plant
and equipment of ¥2,841 million and an increase in purchases of marketable securities of ¥3,378 million.

For the
year ended March 31, 2009, ¥43,373 million of cash outflows was mainly due to additions to property, plant and equipments of ¥38,501 million and purchases of marketable securities of ¥3,609 million.

For the year ended March 31, 2008, ¥35,681 million of cash outflows was mainly due to additions to property, plant and
equipments of ¥35,660 million.

Net cash used in financing activities was ¥122,779 million for the year ended
March 31, 2010 while net cash provided by financing activities was ¥81,874 million for the year ended March 31, 2009.

For the year ended March 31, 2010, ¥122,779 million of the cash outflows was mainly due to a decrease in short-term
borrowings of ¥109,100 million and a decrease in dividends paid to shareholders of Nidec Corporation of ¥7,661 million.

For the year ended March 31, 2009, ¥81,874 million of cash inflows was mainly due to an increase in short-term borrowings
of ¥153,934 million for the purpose of increasing cash on hand in response the global recession. On the other hand, the cash outflows were primarily due to redemption of corporate bonds of ¥26,412 million and purchases of treasury
stock of ¥23,775 million.

Net cash provided by financing activities was ¥81,874 million for the year ended
March 31, 2009 while net cash used in financing activities was ¥35,323 million for the year ended March 31, 2008. The increased cash inflows of ¥117,197 million in financing activities were due mainly to an increase in
short-term borrowings of ¥169,057 million, including those for the purpose of increasing cash on hand in response to the global financial crisis. We aimed to manage our cash on hand depending on the changing market conditions. In April
2009, we repaid ¥85,300 million or a portion of the increased short-term borrowings. Cash and cash equivalents decreased by a similar amount. The increase in short-term borrowings offset redemption of corporate bonds of
¥26,412 million, purchases of treasury stock of ¥23,756 million and an increase in dividends paid of ¥1,457 million.

For the year ended March 31, 2009, ¥81,874 million of cash inflows was mainly due to an increase in short-term borrowings
of ¥153,934 million for the purpose of increasing cash on hand in response to the global recession. On the other hand, the cash outflows were primarily due to redemption of corporate bonds of ¥26,412 million and purchases of
treasury stock of ¥23,775 million.

For the year ended March 31, 2008, ¥35,323 million of cash outflows was
mainly due to a decrease in short-term borrowings of ¥15,123 million, payments for additional investments in subsidiaries of ¥8,043 million and dividends paid to shareholders of Nidec Corporation of ¥7,242 million.

As a result of the foregoing factors and the effect of exchange rate changes, our total outstanding balance of cash and cash equivalents
decreased ¥77,657 million from ¥200,966 million as of March 31, 2009 to ¥123,309 million as of March 31, 2010. Currency of cash and cash equivalents consist primarily of U.S. dollar, Japanese yen and Chinese
yuan.

We believe that cash generated from operating activities are sufficient to meet our cash obligations for the current
fiscal year.

C. Research and Development, Patents and Licenses, etc.

In order to remain competitive, we need to maintain the ability to create products with specialized quality attributes that precisely meet
the evolving performance and environmental requirements of our customers. In addition to the continued emphasis on improved running accuracy, controllability, compactness, operational quietness and energy efficiency, we have our research and
development activities oriented further toward cost and ecology conscious designs that require less raw materials, thus reducing the environmental burden and manufacturing cost of our products.

The largest portion of our research and development costs incurred in recent years has been primarily associated with the development of
small- to mid-size motors, where priority is placed on:



| |  |  | higher rotational speed and accuracy,
| | - |  | -------------------------------------

| |  |  | processing and inspection technology for greater production line efficiency,
| | - |  | ----------------------------------------------------------------------------

| |  |  | low-cost automation system development,
| | - |  | ---------------------------------------

| |  |  | motor design less dependent on raw material, such as steel and aluminum, and
| | - |  | ----------------------------------------------------------------------------

| |  |  | parts manufacturing expertise that facilitates internalization of production process.
| | - |  | -------------------------------------------------------------------------------------

As of March 31, 2010, we employed 1,775 people engaged in research and development activities mainly in Japan as well as in Germany,
Vietnam, China, Taiwan, Italy, the United States, Spain, Mexico, Thailand, Poland, Korea and Singapore.

We incurred research
and development expenses of ¥29,583 million, ¥26,825 million and ¥24,713 million for the fiscal years ended March 31, 2008, 2009 and 2010, respectively.

Much of our research and development is conducted by our domestic subsidiaries, which we then reimburse for costs incurred. We also
cooperate with our affiliates to conduct significant research and development. We anticipate spending approximately ¥33,000 million on research and development in the year ending March 31, 2011. We believe that our research and
development expenses are sufficient for sustaining our competitiveness in the motor industry and other industries.

D. Trend Information.

The information required by this item is set forth in  Operating Results and Item 4. Information
on the Company  B. Business Overview of this annual report.

E. Off-Balance Sheet Arrangements.

We have guaranteed approximately ¥146 million ($1,569 thousand) of bank loans for employees for their housing costs. If an
employee defaults on his or her loan payments, we are required to perform under such guarantees. The undiscounted maximum amount of our obligation to make future payments in the event of defaults is approximately ¥146 million ($1,569
thousand). The current carrying amount of the liabilities for our obligations under the guarantees is zero.

##### Table of Contents

We excluded unrecognized tax benefits from the above contractual obligation table as we are
unable to make reasonable estimates of the period of settlements. As of March 31, 2010, we had the unrecognized tax benefits of ¥4,887 million ($52,526 thousand). For further information related to the unrecognized tax benefits, see Note 18
to our consolidated financial statements included in this annual report.

Our capital commitments as of March 31, 2010
principally consisted of commitments to purchase property, plant and equipment. Commitments outstanding for the purchase of property, plant and equipment and other assets decreased from approximately ¥9,104 million on March 31, 2009 to
approximately ¥2,115 million on March 31, 2010, and increased from approximately ¥8,389 million on March 31, 2008 to approximately ¥9,104 million on March 31, 2009, respectively. Our commitments coming due
during the year ended March 31, 2010 were mainly related to payments for the expansions of the Shiga Technical Center and the Nagano Technical Center, which are two of our Japan-based R&D facilities. The increase in commitments for the year
ended March 31, 2009 was due mainly to the expansion of the Shiga Technical Center, one of our Japan-based R&D facilities. We expect to make capital expenditures in addition to those for which we have outstanding commitments.

For a further discussion on our commitments, see Notes 23 and 24 to our consolidated financial statements included in this annual report.

|Toshinari Sato
Chief Information Officer (CIO)
In charge of supervising System Processing Dept.

Our Board of Directors has the ultimate
responsibility for the administration of our affairs. Our Articles of Incorporation provide for not more than twenty Directors. Directors are elected at a general meeting of shareholders, and the normal term of office of Directors is one year,
although they may serve any number of consecutive terms. The Board of Directors elects one or more Representative Directors, who have the authority individually to represent us. The Board of Directors may also elect one Chairman of the Board of
Directors, one President, one or more Executive Vice Presidents, First Senior Vice Presidents, Senior Vice Presidents and Vice Presidents. Shigenobu Nagamori is the Representative Director, President and Chief Executive Officer. Hiroshi Kobe is the
Representative Director, Executive Vice President and Chief Operating Officer, and Masuo Yoshimatsu is a Member of the Board, Senior Vice President and Chief Financial Officer. Our Executive Officers serve at the discretion of the Board of
Directors.

Corporate Auditors

Our Articles of Incorporation provide for not more than five Corporate Auditors. Currently, we have five Corporate Auditors: Hideo
Asahina, Takashi Iwata, Susumu Ono, Chihiro Suematsu and Kiichiro Kobayashi. The Corporate Auditors may not at the same time be directors, officers or employees of us or any of our subsidiaries, and at least one-half of them must be a person who has
never been a director, officer or employee of us or any of our subsidiaries at any time prior to their election as a Corporate Auditor. Corporate Auditors are elected at a general meeting of shareholders, and the normal term of office of a Corporate
Auditor is four years, although they may serve any number of consecutive terms.

Two of our Corporate Auditors, Hideo Asahina
and Takashi Iwata are full-time Corporate Auditors. Except Takashi Iwata, all of our Corporate Auditors are from outside the Nidec group. Our five Corporate Auditors form our Board of Corporate Auditors. Corporate Auditors are under a statutory duty
to review the administration of our affairs by the Directors, to examine our financial statements and business reports to be submitted by the Board of Directors to the general meetings of shareholders and to report their opinions thereon to the
shareholders. They are required to attend meetings of the Board of Directors and are entitled to express their opinions, but they are not entitled to vote. Corporate Auditors also have a statutory duty to provide their report to the Board of
Corporate Auditors, which must submit its auditing report to the Representative Directors. The Board of Corporate Auditors also determines matters relating to the duties of the Corporate Auditors, such as auditors policy and methods of
investigation of our affairs.

In addition to Corporate Auditors, we must appoint independent certified public accountants,
who have the statutory duties of examining the financial statements to be submitted by the Board of Directors to the annual general meetings of shareholders, reporting thereon to the Board of Corporate Auditors and the Representative Directors, and
examining the financial statements to be filed with the Minister of Finance of Japan.

No family relationship exists among any
of our directors, corporate auditors and executive officers. None of our directors, corporate auditors or executive officers is party to a service contract with us that provides for benefits upon termination of employment.

|Note: | The number of employees increased by 19,908 as of March 31, 2010 compared with March 31, 2009 mainly due to increased production by existing production sites
to meet increased demand overseas.

Japan

In Japan, as of March 31, 2010, we had 8,758 employees. Of these employees, 4,032 employees were engaged in manufacturing operations,
1,500 in research and development and 1,475 in sales activities.

Most of our employees receive compensation on the basis of
fixed annual salaries and twice-a-year bonuses. In addition, we have a separate bonus system to reward employees who make significant technological contributions to our operations as reflected primarily by patent registrations. We emphasize and
reward individual skills and performance. We have started to incorporate performance-linked elements into our domestic compensation and promotion systems to make us more competitive in Japan in recruiting and retaining highly-skilled individuals.
Under our retirement allowance system, eligible employees are entitled to a lump-sum allowance and a retirement annuity upon their retirement.

In Japan, although Nidec has no labor union, labor unions have been organized in some of our subsidiaries. There have been no material
strikes or labor disputes. We believe that the relationship between us and our employees is favorable.

Overseas

As of March 31, 2010, we had 87,724 employees overseas. Of these employees, 78,287 employees were engaged in manufacturing
operations, 275 in research and development and 597 in sales activities.

No material strikes or labor disputes have occurred
overseas and we believe that the relationship between us and our employees is favorable.

For
the fiscal years ended March 31, 2008, 2009 and 2010, we entered into service transactions with S.N. Kohsan, an entity indirectly owned by Mr. Nagamori, our President and Chief Executive Officer (CEO), involved in asset
management, where S.N. Kohsan provided restaurant services at the time to entertain our customers. We paid a total of approximately ¥3 million for the services for each of the fiscal years.

For each of the same three-year periods, Nidec-Shimpo Corporation, our wholly owned subsidiary, paid a total of approximately
¥10 million, ¥12 million and ¥12 million, respectively, to Green Kohsan, an entity wholly owned by Mr. Nagamori, under their lease agreement for office equipment.

In addition, we purchased iron cores from Hamaguchi Denski Seisakusho Co., Ltd., in which one of our directors,
Mr. Yasuo Hamaguchi, directly and indirectly holds an ownership interest, for a total of approximately ¥21 million, ¥14 million and ¥44 million for the iron cores, and sold materials to Hamaguchi Denki Seisakusho
for a total of approximately ¥6 million, ¥4 million and ¥4 million, for the fiscal years ended March 31, 2008, 2009 and 2010, respectively.

In addition, we entered, and expect to enter in the future, into various manufacturing, sales and purchase transactions with our
affiliates, most of which involve the production of components or products that we sell.

Loan to S.N. Kohsan

In December 2008, we advanced a loan of ¥14,500 million to S.N. Kohsan, a company indirectly owned by the CEO. The loan was
guaranteed by the CEO and collateralized by a pledge of 4,500,000 of the CEOs shares in us. The loan had a term of 5 years and accrued interest quarterly at an annual rate of 2.4%. The loan was repaid in full on February 17, 2009, shortly
after we and the CEO determined that the loan was not permitted under Section 402 of the U.S. Sarbanes-Oxley Act of 2002. S.N. Kohsan obtained the funds to repay the loan through the sale of a total of 3,356,000 of its shares in us through the
J-NET and on the Osaka Securities Exchange. Of these shares, 2,917,800 were purchased by us through the J-NET for a total of ¥12,867 million. A special committee of our Board of Corporate Auditors conducted an independent investigation of this
matter with the assistance of independent counsel and concluded that the failure to comply with Section 402 was inadvertent. We voluntarily brought this matter to the attention of the SEC. The Division of Enforcement of the SEC advised us that
it was conducting an informal inquiry into the issue, and we cooperated fully with the informal inquiry. We have subsequently been advised by the Staff of the Division of Enforcement that its investigation has been concluded and that the Staff will
not recommend that enforcement proceedings be commenced.

Dividend Policy

We generally pay cash dividends twice per year. Our Board of Directors resolves a year-end dividend to be paid following the end of each
fiscal year. If approved by resolution of our Board of Directors, the dividend is paid to holders of record as of the immediately preceding March 31. In addition to year-end dividends, we may pay interim dividends in the form of cash
distributions from our retained earnings to our shareholders of record as of September 30 in each year by resolution of our Board of Directors. If paid, the interim dividend is generally paid in December and the year-end dividend is generally
paid in June.

##### Table of Contents

Based on the viewpoint that shareholders own the company, we aim to maximize
shareholder value by achieving higher growth, profit and stock prices over the long-term with a vision that enables us to effectively respond to the constantly changing business environment. We seek to distribute our profits to shareholders through
regular dividend payments, and aim to further increase our dividend payments to around 30% of our consolidate net income, subject to future earnings, financial condition and other factors, including statutory and other restrictions with respect to
the payment of dividends.

Reserves are used to strengthen our management structure and expand our business to improve
profitability.

Our Board of Directors has determined the year-end dividend to be ¥40.0 per share for the fiscal year
ended March 31, 2010. As a result, together with the interim dividend of ¥25.0 per share, the full-year dividend for the fiscal year is expected to be ¥65.0 per share, an increase of ¥5.0 from the fiscal year ended
March 31, 2009. The dividend payout ratio, which is obtained by dividing the dividend declared for the year by net income attributable to Nidec Corporation, for this fiscal year is expected to be approximately 17%.

The following table sets forth the year-end and interim dividends paid to holders of record of our common stock for each of the record
dates shown. Yen per share dividend amounts are translated solely for your convenience into U.S. dollars at the noon buying rate for Japanese yen announced by the Federal Reserve Bank of New York on the dividend payment date.

|* | A two-for-one stock split on the Companys common stock effective November 18, 2005 was implemented for shareholders of record as of September 30, 2005.
The dividend per share have been accordingly adjusted to reflect the effect of the stock split.
|- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|** | Our Board of Directors recommended the dividend to be paid, which recommendation was then approved by shareholders at the general meeting of shareholders in June 2006.
Under the Company Law of Japan (which replaced the Commercial Code in May 2006), however, our Board of Directors may, except in certain circumstances, pay dividends without shareholder approval.

Dividends paid to shareholders outside Japan on shares of common stock or ADSs are generally subject to a Japanese withholding tax at the
temporary rate of 7% (applicable until December 31, 2011) or standard rate of 15% (applicable on January 1, 2012 and thereafter). Reduced rates for withholding apply to shareholders in some countries which have income tax treaties with
Japan. U.S. holders are generally subject to a maximum withholding rate of 10%. If the applicable tax rate under the domestic tax law is lower than that promulgated under the applicable income tax treaty, then the domestic tax rate is still
applicable due to the so-called preservation doctrine.

InformationExchange Controls and Item 10.E. Additional InformationTaxation.

Objects and Purposes in Our Articles of Incorporation

Article 2 of our Articles of Incorporation, which are attached as Exhibit 1.1 to this annual report, provides our corporate objects and
purposes, including:



| |  |  | manufacture, sales and development of electric, electronic, precision, industrial and other equipment, machines, drives, components and other products,
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | insurance agent business,
| | - |  | -------------------------



| |  |  | sales, purchase, lease, brokering, and management of moveable and real property, and
| | - |  | ------------------------------------------------------------------------------------



| |  |  | travel agent and advertising businesses.
| | - |  | ----------------------------------------

Provisions Regarding Our Directors

There is no provision in our Articles of Incorporation as to a Directors power to vote on a proposal in which the Director is
materially interested but, under the Company Law of Japan and our Regulations of the Board of Directors, a Director is required to refrain from voting on such matters at meetings of the Board of Directors.

The Company Law provides that compensation for directors is determined at a general meeting of shareholders of a company. Within the
upper limit approved by the shareholders meeting, the board of directors will determine the amount of compensation for each director. The board of directors may, by its resolution, leave such decision to the discretion of the companys
representative director.

The Company Law requires directors to perform their duties faithfully on behalf of the
company, thus subjecting directors to a duty of loyalty (chujitsu gimu). This duty is supplemented by other duties such as to avoid self-dealing and competition with the corporation as well as to abide by all laws and regulations,
articles of incorporation and resolutions of general meetings of shareholders.

##### Table of Contents

Directors can be held liable for damages caused by their negligence in performing their
duties, including any action to violate a law, an ordinance or articles of incorporation. For example, directors can be liable for damages caused by declaring an unlawful dividend or distribution of money or by offering some benefit to a shareholder
in exchange for the exercise of that shareholders rights as shareholder.

There is no mandatory retirement age for our
Directors under the Company Law or our Articles of Incorporation.

There is no requirement concerning the number of shares one
individual must hold in order to qualify him or her as a Director either under the Company Law or our Articles of Incorporation.

Holding
of Our Shares by Foreign Investors

There are no limitations on the rights of non-residents or foreign shareholders to hold
or exercise voting rights on our shares imposed by the laws of Japan or our Articles of Incorporation or our other constituent documents.

Rights of Our Shareholders

Set forth below is information relating to our common stock, including brief summaries of the relevant provisions of our Articles of
Incorporation and Share Handling Regulations, as currently in effect, and of the Company Law and related legislation.

General

Our authorized share capital is 480,000,000 shares, of which 145,075,080 shares were issued and outstanding as of
March 31, 2010.

On January 5, 2009, a new central clearing system for shares of Japanese listed companies was
established pursuant to the Law Concerning Book-Entry Transfer of Corporate Bond, Stocks, etc. (including regulations promulgated thereunder, the Book-Entry Law), and the shares of all Japanese companies listed on any Japanese stock
exchange, including our shares, became subject to the new central clearing system. On the same day, all existing share certificates for such shares became null and void. At present, Japan Securities Depository Center, Inc., or JASDEC, is
the only institution that is designated by the relevant authorities as a clearing house which is permitted to engage in the clearing operations of shares of Japanese listed companies under the Book-Entry Law. Under the new clearing system, in order
for any person to hold, sell or otherwise dispose of shares of Japanese listed companies, it must have an account at an account managing institution unless such person has an account at JASDEC. Account managing institutions are financial
instruments firms (i.e., securities companies), banks, trust companies and certain other financial institutions which meet the requirements prescribed by the Book-Entry Law.

Under the Book-Entry Law, any transfer of such shares is effected through entry in the books maintained under the new central clearing
system, and title to the shares passes to the transferee at the time when the transferred number of the shares is recorded at the transferees account at an account managing institution. The holder of an account at an account managing
institution is presumed to be the legal owner of the shares held in such account.

Under the Company Law and the Book-Entry
Law, in order to assert shareholders rights against us, a shareholder must have its name and address registered in our register of shareholders, except in limited circumstances. Under the new clearing system, such registration is made upon our
receipt of necessary information from JASDEC. See Share Registrar and Record Date below.

The registered beneficial holder of deposited shares underlying the ADSs is the depositary
for the ADSs. Accordingly, holders of ADSs will not be able to directly assert shareholders rights.

Shareholders Rights to
Bring Actions Against Directors

The Company Law provides for the Japanese shareholder derivative action mechanism, which
allows any shareholder who has held a share for the previous six months to demand that the corporation take action to protect the company and enforce a directors duties. Derivative actions may be brought to enforce the liability of
directors which refers to situations including, but not limited to, that where directors engage in self-interested transactions, or violate any law, ordinance or the articles of incorporation. If the board has not instituted an action within
sixty days, the plaintiff-shareholder may initiate a lawsuit as a derivative action. The Company Law provides an exception to the sixty day waiting period, however, for cases in which waiting sixty days might cause the company irreparable damage. In
such cases, the shareholder may institute the action immediately, but after having brought the action must notify the company without delay. So, for example, if a company might suffer irreparable damage from an illegal act of a director, a
shareholder who has owned a share (in our case, under our Articles of Incorporation, excluding a holder of shares representing less than one unit under the unit share system described below) continuously for the previous six months may seek a
provisional injunction prohibiting the director from performing the illegal act.

Distribution of Surplus

General

Under the
Company Law, distributions of cash or other assets by joint stock corporations to their shareholders, so called dividends, are referred to as distributions of Surplus (Surplus is defined in Restriction on
Distributions of Surplus below). We may make distributions of Surplus to the shareholders any number of times per fiscal year, subject to certain limitations described in Restriction on Distributions of Surplus. Under the
Company Law, distributions of Surplus are required to be authorized by a resolution of a general meeting of shareholders unless the board of directors is so authorized under the articles of incorporation. Our Articles of Incorporation provide that
the Board of Directors has the authority to decide to make distribution of Surplus except for limited exceptions as provided by the Company Law, since we have satisfied the following requirements:



| | (a) | the normal term of office of our Directors terminates on or prior to the date of conclusion of the ordinary general meeting of shareholders relating to the last fiscal
year ending within the period of one year from the election of the Directors; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | our non-consolidated annual financial statements and certain documents for the last fiscal year present fairly our assets and profit or loss, as required by the
ordinances of the Ministry of Justice.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under our Articles of Incorporation, year-end dividends and interim
dividends, if any, may be distributed to shareholders (or pledgees) appearing in the register of shareholders as of March 31 and September 30 of each year, respectively, pursuant to a resolution of our Board of Directors. In addition, as
stated above, under the Company Law and our Articles of Incorporation, we may make further distributions of Surplus by resolution of our Board of Directors. Under our Articles of Incorporation, we are not obliged to pay any dividends in the form of
cash that are left unclaimed for a period of three years after the date on which they first became payable.

---

##### Table of Contents

Distributions of Surplus may be distributed in cash or in kind in proportion to the number
of shares held by each shareholder. A resolution of our Board of Directors authorizing a distribution of Surplus must specify the kind and aggregate book value of the assets to be distributed, the manner of allocation of such assets to shareholders,
and the effective date of the distribution. If a distribution of Surplus is to be made in kind, we may, pursuant to a resolution of our Board of Directors, grant a right to our shareholders to require us to make such distribution in cash instead of
in kind. If no such right is granted to shareholders, the relevant distribution of Surplus must be approved by a special resolution of a general meeting of shareholders.

Restriction on Distributions of Surplus

When we make a distribution of Surplus, we must, until the aggregate amount of our additional paid-in capital and legal reserve reaches
one-quarter of our stated capital, set aside in our additional paid-in capital and/or legal reserve an amount equal to one-tenth of the amount of Surplus so distributed.

The amount of Surplus at any given time shall be calculated in accordance with the following formula:

A + B + C + D  (E + F + G)

In the above formula:



|    |  |   |  |

##### Table of Contents

The aggregate book value of Surplus distributed by us may not exceed a prescribed
distributable amount (the Distributable Amount), as calculated on the effective date of such distribution. The Distributable Amount at any given time shall be equal to the amount of Surplus less the aggregate of the followings:



| | (a) | the book value of our treasury stock;
| | --- | -------------------------------------



| | (b) | the amount of consideration for our treasury stock disposed of by us after the end of the last fiscal year; and
| | --- | ---------------------------------------------------------------------------------------------------------------



| | (c) | certain other amounts set forth in the ordinances of the Ministry of Justice, including (if the sum of one-half of good will and the deferred assets exceeds the total
of stated capital, additional paid-in capital and legal reserve, each such amount being that appearing on our non-consolidated balance sheet as of the end of the last fiscal year) all or certain part of such exceeding amount as calculated in
accordance with the ordinances of the Ministry of Justice.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If we have become at our option a company with
respect to which consolidated balance sheets should also be taken into consideration in the calculation of the Distributable Amount (renketsu haito kisei tekiyo kaisha), it will be required to further deduct from the amount of Surplus the
excess amount, if any, of (x) the total amount of shareholders equity appearing on our non-consolidated balance sheet as of the end of the last fiscal year and certain other amounts set forth in the ordinances of the Ministry of Justice
over (y) the total amount of shareholders equity and certain other amounts set forth in the ordinances of the Ministry of Justice appearing on our consolidated balance sheet as of the end of the last fiscal year.

If we have prepared interim financial statements as described below, and if such interim financial statements have been approved by the
Board of Directors or (if so required by the Company Law) by a general meeting of shareholders, the Distributable Amount must be adjusted to take into account the amount of profit or loss, and the amount of consideration for our treasury stock
disposed of by us, during the period in respect of which such interim financial statements have been prepared. We may prepare non-consolidated interim financial statements consisting of a balance sheet as of any date subsequent to the end of the
last fiscal year and an income statement for the period from the first day of the current fiscal year to the date of such balance sheet. Interim financial statements so prepared by us must be approved by the Board of Directors and audited by our
independent auditors, as required by the ordinances of the Ministry of Justice.

For information as to Japanese taxes on
dividends, see E. TaxationJapanese Taxation.

Capital and Reserves

When we issue new shares, the entire amount of cash or other assets paid or contributed by subscribers for those new shares is required to
be accounted for as stated capital, although we may account for an amount not exceeding one-half of the amount of such cash or assets as additional paid-in capital by resolution of the Board of Directors.

We may reduce our additional paid-in capital or legal reserve generally by resolution of a general meeting of shareholders, and in the
case of reduction of additional paid-in capital and if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as stated capital. On the other hand, we may reduce our stated capital generally by
special resolution of a general meeting of shareholders and, if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as additional paid-in capital. In addition we may reduce our Surplus and
increase either (i) stated capital or (ii) additional paid-in capital and/or legal reserve by the same amount, in either case by resolution of a general meeting of shareholders.

Stock Splits

We may at any time split the issued shares into a greater number of shares by resolution of our Board of Directors. When a stock split is
to be made, so long as the only class of our outstanding stock is our common stock, we may increase the number of authorized shares to the extent that the ratio of such increase in authorized shares does not exceed the ratio of such stock split by
amending our Articles of Incorporation, which amendment may be made without approval by shareholders.

Before a stock split,
we must give public notice of the stock split, specifying the record date therefor, not less than two weeks prior to such record date. Under the new clearing system, we must also give notice to JASDEC regarding a stock split at least two weeks prior
to the relevant effective date. On the effective date of the stock split, the numbers of shares recorded in all accounts held by our shareholders at account managing institutions or JASDEC will be increased in accordance with the applicable ratio.

Japanese Unit Share System

Our Articles of Incorporation provide that 100 shares of common stock constitute one unit. The Company Law permits us, by
resolution of our Board of Directors, to reduce the number of shares that constitutes one unit or abolish the unit share system, and amend our Articles of Incorporation to this effect without the approval of a shareholders meeting. The number
of shares constituting a unit may not exceed 1,000 shares.

Transferability of Shares Representing Less Than One Unit

Under the new clearing system, shares constituting less than one unit are transferable. Under the rules of the Japanese stock exchanges,
however, shares constituting less than one unit do not comprise a trading unit, except in limited circumstances, and accordingly may not be sold on the Japanese stock exchange.

Right of a Holder of Shares Representing Less Than One Unit to Require Us to Purchase Its Shares

A holder of shares representing less than one unit may at any time require us to purchase our shares through the relevant account
management institution. These shares will be purchased at:



| |  |  | the closing price of the shares reported by the Osaka Securities Exchange Co., Ltd. (the Osaka Securities Exchange) on the day when the
request to purchase is made; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if no sale takes place on such stock exchange on that day, the closing price of the shares reported by the Tokyo Stock Exchange, Inc. (the Tokyo
Stock Exchange) on such day; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if no sale takes place on either of such stock exchanges on such day, the price at which the shares are first traded on the Osaka Securities Exchange
on the next day; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if no sale takes place on such stock exchange on such day, the price at which the shares are first traded on the Tokyo Stock Exchange on such day; or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if no sale takes place on either of such stock exchanges on such day, the price at which the shares are first traded on either of such stock exchanges,
provided that, if the shares are traded on both such exchanges on the same day, the relevant price shall be the price at which the shares are first traded on the Osaka Securities Exchange.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

In such case, we will request payment of an amount equal to the brokerage commission
applicable to the shares purchased. However, because holders of ADSs representing less than one unit are not able to withdraw the underlying shares from deposit, these holders will not be able to exercise this right as a practical matter.

Voting Right of a Holder of Shares Representing Less Than One Unit

A holder of shares representing less than one unit cannot exercise any voting rights pertaining to those shares. In calculating the quorum
for various voting purposes, the aggregate number of shares representing less than one unit will be excluded from the number of outstanding shares. A holder of shares representing one or more whole units will have one vote for each unit of shares,
except as stated in  Voting Rights below.

A holder of shares representing less than one unit does not have
any rights relating to voting, such as the right to participate in a demand for the resignation of a director, the right to participate in a demand for the convocation of a general meeting of shareholders and the right to join with other
shareholders to propose an agenda item to be addressed at a general meeting of shareholders. In addition, a holder of shares constituting less than one unit does not have the right to institute a representative action by shareholders.

Other Rights of a Holder of Shares Representing Less Than One Unit

In accordance with the Company Law, our Articles of Incorporation provide that a holder of shares representing less than one unit does not
have any other rights of a shareholder in respect of those shares, other than those provided by our Articles of Incorporation including the following rights:



| |  |  | to receive distribution of dividends;
| | - |  | -------------------------------------



| |  |  | to receive shares, cash or other assets in case of consolidation or split of shares, exchange or transfer of shares or corporate merger;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to be allotted rights to subscribe for new shares and other stock acquisition rights when such rights are granted to shareholders; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to participate in any distribution of surplus assets upon liquidation.
| | - |  | ----------------------------------------------------------------------

Ordinary General Meeting of Shareholders

We normally hold our annual general meeting of shareholders in June of each year. In addition, we may hold an extraordinary general
meeting of shareholders whenever necessary by giving at least two weeks advance notice. Under the Company Law, notice of any shareholders meeting must be given to each shareholder having voting rights or, in the case of a non-resident
shareholder, to his resident proxy or mailing address in Japan in accordance with our Share Handling Regulations, at least two weeks prior to the date of the meeting.

Voting Rights

A
shareholder is generally entitled to one vote per one unit of shares, as described under  Japanese Unit Share System above. In general, under the Company Law, a resolution can be adopted at a general meeting of shareholders by a
majority of the voting rights represented at the meeting. The Company Law and our Articles of Incorporation require a quorum for the election of Directors and Corporate Auditors of not less than one-third of the voting rights. Our shareholders are
not entitled to cumulative voting in the election of Directors. A corporate shareholder whose outstanding voting rights are in turn more than one-quarter directly or indirectly owned by us does not have voting rights. Shareholders may exercise their
voting rights through proxies, provided that those proxies are also shareholders who have voting rights.

##### Table of Contents

The Company Law and our Articles of Incorporation provide that certain important matters
shall be approved by a special resolution of general meeting of shareholders. Our Articles of Incorporation provide that the quorum for a special resolution is one-third of the total number of voting rights and the approval of at least
two-thirds of the voting rights presented at the meeting is required for adopting a special resolution. Such important matters include:



| | (a) | reduction of the stated capital;
| | --- | --------------------------------



| | (b) | amendment to the Articles of Incorporation;
| | --- | -------------------------------------------



| | (c) | establishment of a 100% parent-subsidiary relationship by way of share exchange or share transfer;
| | --- | --------------------------------------------------------------------------------------------------



| | (d) | dissolution, merger or consolidation;
| | --- | -------------------------------------



| | (e) | company split;

| | (g) | taking over of the whole of the business of any other corporation;
| | --- | ------------------------------------------------------------------



| | (h) | removal of a Corporate Auditor;

| | (i) | any issuance of shares or transfer of existing shares as treasury stock to persons other than the shareholders at a specially favorable price;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------



| | (j) | any issuance of stock acquisition rights (including those incorporated in bonds with stock acquisition rights) to persons other than the shareholders under
specially favorable conditions;

| | (m) | distribution of Surplus in kind with respect to which shareholders are not granted the right to require us to make such distribution in cash instead of in kind; and
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (n) | exemption from a portion of liability of the Directors, Corporate Auditors or independent auditors.
| | --- | ---------------------------------------------------------------------------------------------------

However, under the Company Law, no shareholder approval, whether by an ordinary resolution or a special resolution at a general meeting
of shareholders, is required for any matter described in (a) through (g) above, and such matter may be decided by the Board of Directors, if it satisfies certain criteria prescribed by the Company Law as are necessary to determine that its
impact is immaterial.

The voting rights of holders of ADSs are exercised by the depositary based on instructions from those
holders. See American Depositary Receipts.

##### Table of Contents

Subscription Rights

Holders of shares have no pre-emptive rights. Authorized but unissued shares may be issued at such times and upon such terms as our Board
of Directors determines, subject to the limitations as to the issue of new shares at a specially favorable price in which case a special resolution of general meeting of shareholders is required as described in - Voting
Rights above. The Board of Directors may, however, determine that shareholders be given subscription rights in connection with a particular issue of new shares. In this case, such rights must be given on uniform terms to all shareholders as of
a specified record date of which not less than two weeks prior public notice must be made. Each of the shareholders to whom such rights are given must also be given at least two weeks prior notice of the date on which such rights will
expire.

Stock Acquisition Rights

We may issue stock acquisition rights (shinkabu yoyakuken) or bonds with stock acquisition rights (shinkabu yoyakuken-tsuki
shasai). Except where the issue would be on specially favorable conditions, the issue of stock acquisition rights or bonds with stock acquisition rights may be authorized by a resolution of the Board of Directors. Subject to the
terms and conditions thereof, holders of stock acquisition rights may acquire a prescribed number of shares by exercising their stock acquisition rights and paying the exercise price at any time during the exercise period thereof. Upon exercise of
stock acquisition rights, we will be obliged to either issue the relevant number of new shares or transfer the necessary number of existing shares held by us as treasury stock to the holder.

Liquidation Rights

In
the event of liquidation, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed among the shareholders in proportion to the number of shares they own.

Liability to Further Calls or Assessments

All of our currently outstanding shares, including shares represented by the ADSs, are fully paid and nonassessable.

Share Registrar

The
Sumitomo Trust and Banking Company, Limited is the share registrar for the shares. Sumitomo Trusts office is located at 5-33, Kitahama 4-chome, Chuo-ku, Osaka, 540-0041, Japan. Under the new clearing system, Sumitomo Trust maintains our
register of shareholders and records transfers of record ownership upon our receipt of necessary information from JASDEC and other information in the register of shareholders.

Record Date

The close
of business on March 31 is the record date for our year-end dividends, if paid, and the close of business on September 30 is the same for our interim dividends, if paid. A holder of shares constituting one or more units who is
registered as a holder on our register of shareholders at the close of business as of March 31 is also entitled to exercise shareholders voting rights at the annual general meeting of shareholders with respect to the fiscal year ending on
March 31. In addition, we may set a record date for determining the shareholders entitled to other rights and for other purposes by giving at least two weeks public notice.

Under the Book-Entry Law, we are required to give notice of each record date to JASDEC at least two weeks prior to such record date.
JASDEC is required to promptly give us notice of the names and addresses of our shareholders, the numbers of shares held by them and other relevant information as of such record date.

##### Table of Contents

The shares generally trade ex-dividend or ex-rights in the Japanese stock exchanges on the
third business day before a record date (or if the record date is not a business day, the fourth business day prior thereto), for the purpose of dividends or rights offerings.

Repurchase by Nidec of Shares

Under the Company Law and our Articles of Incorporation, we may acquire our shares (i) by soliciting all our shareholders to offer to
sell our shares held by them (in this case, the certain terms of such acquisition, such as the total number of the shares to be purchased and the total amount of consideration, shall be set by an ordinary resolution of a general meeting of
shareholders in advance, and acquisition shall be effected pursuant to a resolution of the Board of Directors), (ii) from a specific shareholders other than any of our subsidiaries (pursuant to a special resolution of a general meeting of
shareholders), (iii) from any of our subsidiaries (pursuant to a resolution of our Board of Directors), or (iv) by way of purchase on any Japanese stock exchange on which our shares are listed or by way of tender offer (in either case
pursuant to an ordinary resolution of a general meeting of shareholders). In the case of (ii) above, any other shareholder may make a request to the Board of Directors that such other shareholder be included as a seller in the proposed
purchase, provided that no such right will be available if the purchase price or any other consideration to be received by the relevant specific shareholder will not exceed the last trading price of the shares calculated in a manner set forth in the
ordinances of the Ministry of Justice.

These acquisitions are subject to the condition that the aggregate amount of the
purchase price must not exceed the Distributable Amount as described in  Distribution of Surplus above. We may hold our shares acquired in compliance with the provisions of the Company Law, and may generally dispose of or cancel
such shares by resolution of the Board of Directors.

In addition, we may acquire our shares by means of repurchase of any
number of shares constituting less than one unit upon the request of the holder of those shares, as described under  Japanese Unit Share System above.

American Depositary Receipts

JPMorgan Chase Bank, N.A., as depositary, will issue the American Depositary Shares, or ADSs. Each ADS will represent an ownership
interest in one-fourth of a share of our common stock deposited with the custodian, as agent of the depositary, under the deposit agreement among us, the depositary and you as an ADS holder. Each ADS will also represent any securities, cash or other
property deposited with the depositary but not distributed to ADS holders. Your ADSs will be evidenced by what are known as American depositary receipts or ADRs. The depositarys office is located at 1 Chase Manhattan Plaza, Floor 58 New York,
NY 10005.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold
ADSs directly, by having an ADS registered in your name on the books of the depositary, you are an ADS holder. If you hold the ADSs through your broker or financial institution nominee, your must rely on the procedures of such broker or financial
institution to assert the rights of an ADS holder. You should consult with your broker or financial institution to find out what those procedures are.

Because the depositarys nominee will actually be the registered owner of the shares, you will have to rely on it to exercise your
rights as a shareholder on your behalf. The obligations of the depositary and its agents are set out in the deposit agreement. The deposit agreement and the ADSs governed by New York Law.

amended as attached as exhibits to the registration statements on Form F-6 filed with the SEC on September 7, 2001, December 12, 2003 and June 13, 2007. See H. Documents on Display.

For a description of the fees relating to the ADSs, see Item 12D.American Depositary Shares.

Reporting of Substantial Shareholdings

The Financial Instruments and Exchange Law of Japan and its related regulations require any person who has become, solely or jointly, a
holder of more than 5% of the total issued shares with voting rights of a company that is listed on any Japanese stock exchange to file a report with the Director of the competent Local Finance Bureau of the Ministry of Finance within five business
days. With certain exceptions, a similar report must also be filed in respect of any subsequent change of 1% or more in the holding of shares with voting rights or of any specified changes set out in any previously-filed reports. For this purpose,
shares issuable to such person upon exercise of stock acquisition rights are taken into account in determining both the number of shares with voting rights held by the holder and the issuers total issued shares with voting rights.

Daily Price Fluctuation Limits under Japanese Stock Exchange Rules

Share prices on Japanese stock exchanges are determined on a real-time basis by the equilibrium between bids and offers. These exchanges
are order-driven markets without specialists or market makers to guide price formation. To prevent excessive volatility, these exchanges set daily upward and downward price fluctuation limits for each share, based on the previous days closing
price. Although transactions may continue at the upward or downward limit price if the limit price is reached on a particular trading day, no transactions may take place outside these limits. Consequently, an investor wishing to sell at a price
above or below the relevant daily limit may not be able to sell shares at such price on a particular trading day, or at all.

On June 16, 2010, the closing price of our shares on the Osaka Securities Exchange was ¥8,810 per share. The following
table shows the daily price limit for a stock on the Osaka Securities Exchange with a closing price of between ¥5,000 and ¥10,000 per share, as well as the daily price limit if our per share price were to rise to between ¥10,000 and
¥20,000, or fall to between ¥3,000 and ¥5,000. Other daily price limits would apply if our per share price moved to other ranges.

C. Material Contracts.

Except as described elsewhere in this Annual Report, we have not entered into any material contracts, other than in the ordinary course of
business, within the two years immediately preceding the date of this document or any contract, other than in the ordinary course of business, which contains any provision under which we have any obligation or entitlement which is material to us as
at the date of this document.

D. Exchange Controls.

Acquisition or Disposition of Shares or ADS

The Foreign Exchange and Foreign Trade Law of Japan governs certain aspects relating to the acquisition and holding of securities by
non-residents of Japan and foreign investors.

In general, acquisition of shares of stock of a
Japanese company listed on any Japanese stock exchange by a non-resident of Japan from a resident of Japan is not subject to any prior notification requirement, but subject to a post reporting requirement by the resident.

If a foreign investor acquires shares of a Japanese company listed on a Japanese stock exchange and as a result of this acquisition
directly or indirectly holds, aggregated with existing holdings, 10% or more of the issued shares of the company, the foreign investor is, in general, required to report the acquisition to the Minister of Finance and any other competent ministers
via the Bank of Japan within 15 days from and including the date of acquisition. In exceptional cases, a prior notification is required in respect of the acquisition.

Non-residents of Japan are generally defined as individuals who are not resident in Japan and corporations whose principal
offices are located outside Japan. Branches and other offices of Japanese corporations located outside Japan are considered as non-residents of Japan, and branches and other offices located within Japan of foreign corporations are considered as
residents of Japan. Foreign investors are generally defined to be (i) individuals not resident in Japan, (ii) corporations which are organized under the laws of foreign countries or whose principal offices are located outside
Japan, and (iii) corporations of which (a) 50% or more of the shares are held directly or indirectly by (i) or (ii) above, (b) a majority of officers consists of non-residents of Japan or (c) a majority of officers
having the power of representation consists of non-residents of Japan.

Dividends and Proceeds of Sale

Under the Foreign Exchange and Foreign Trade Law, dividends paid on, and the proceeds of sales in Japan of shares held by non-residents of
Japan may in general be converted into any foreign currency and repatriated abroad. Under the terms of the deposit agreement pursuant to which our ADSs are issued, the depositary is required, to the extent that in its judgment it can convert yen on
a reasonable basis into dollars and transfer the resulting dollars to the United States, to convert all cash dividends that it receives in respect of deposited shares into dollars and to distribute the amount received (after deduction of applicable
withholding taxes) to the holder of ADSs. For additional information regarding our ADSs, see American Depositary Receipts.

This section is based on the Internal Revenue Code of 1986, as amended (the Code), its legislative history, existing and
proposed regulations, published rulings and court decisions and the laws of Japan all as currently in effect, as well as on the income tax treaty between the United States of America and Japan (the Treaty). These laws are subject to
change, possibly on a retroactive basis. We have not requested, and will not request, a ruling from the U.S. Internal Revenue Service (the IRS) with respect to any of the U.S. federal income tax consequences described below, and as a
result there can be no assurance that the IRS will not disagree with or challenge any of the conclusions we have reached and describe herein. In addition, this section is based in part upon the representations of the depositary and the assumption

are a U.S. holder if you are a beneficial owner of shares or ADSs and you are:

If a partnership or other pass-through entity is a beneficial owner of our shares or ADSs, the tax treatment of a partner or other owner
will generally depend upon the status of the partner (or other owner) and the activities of the entity. If you are a partner (or other owner) of a pass-through entity that acquires our shares or ADSs, you should consult your tax advisor regarding
the tax consequences of owning shares or ADSs.

You should consult your own tax advisor regarding the United States
federal, state and local and the Japanese and other tax consequences of owning and disposing of shares and ADSs in your particular circumstances.

In general, and taking into account the earlier assumptions, for United States federal income tax purposes, if you hold ADRs evidencing
ADSs, you will be treated as the owner of the shares represented by those ADRs. Exchanges of shares for ADRs, and ADRs for shares, generally will not be subject to United States federal income tax.

Notwithstanding the foregoing, the U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder
of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying shares (for example, pre-releasing ADSs to persons who do not have the beneficial ownership of
the securities underlying the ADSs). Accordingly, the analysis of the creditability of Japanese taxes and the availability of the reduced rate of tax for dividends received before January 1, 2011 by certain non-corporate U.S. Holders, each as
described below, could be affected by actions taken by intermediaries in the chain of ownership between the holder of ADSs and Nidec if, as a result of such actions, the holders of ADSs are not properly treated as beneficial owners of the underlying
shares. We are not aware of any intention to take any such actions, and accordingly, the remainder of this discussion assumes that holders of ADSs will be properly treated as beneficial owners of the underlying shares.

United States Federal Income Taxation

Taxation of Dividends

Under the United States federal income tax laws, and subject to the passive foreign investment company, or PFIC, rules as discussed below,
if you are a U.S. holder, the gross amount of any dividend paid by Nidec out of its current or accumulated earnings and profits (as determined for United States federal income tax purposes) will be subject to U.S. federal income taxation. If you are
a noncorporate U.S. holder, dividends paid to you in taxable years beginning before January 1, 2011 that constitute qualified dividend income will be taxable to you at a maximum tax rate of 15% provided that you hold the shares or ADSs for more
than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Absent legislation by Congress, for taxable years beginning after December 31, 2010, qualified dividend income will
be taxable to you at the applicable ordinary income tax rates. Dividends we pay with respect to the shares or ADSs generally will be qualified dividend income. You must include any Japanese tax withheld from the dividend payment in this gross amount
even though you do not in fact receive it. The dividend will be taxable to you when you, in the case of shares, or the depositary, in the case of ADSs, receive the dividend, actually or constructively. The dividend will not be eligible for the
dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations. The amount of the dividend distribution that you must include in your income as a U.S. holder will
be the U.S. dollar value of the yen payments made, determined at the spot yen/U.S. dollar rate on the date the dividend distribution is includible in your income, regardless of whether the payment is in fact converted into U.S. dollars. Generally,
any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income to the date you convert the payment into U.S. dollars will be treated as ordinary income or loss and will not
be eligible for the special tax rate applicable to qualified dividend income. The gain or loss generally will be income or loss from sources within the United States for foreign tax credit limitation purposes. Distributions in excess of current and
accumulated earnings and profits, as determined for United States federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in the shares or ADSs and thereafter as capital gain. However, we do not
maintain calculations of our earnings and profits in accordance with U.S. federal income tax principles, and you should therefore assume that any distribution by us with respect to our shares or ADSs will constitute ordinary dividend income.

Subject to certain limitations, the Japanese tax withheld in accordance with the Treaty and paid over to Japan will be
creditable against your United States federal income tax liability. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the maximum 15% tax rate, which applies through December 31,
2010. To the extent a refund of the tax withheld is available to you under Japanese law or under the Treaty, the amount of tax withheld that is refundable will not be eligible for credit against your United States federal income tax liability.

Dividends will be income from sources outside the United States. Dividends paid will, depending on your circumstances, be
passive or general income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit allowable to you.

##### Table of Contents

Taxation of Capital Gains

Subject to the PFIC rules as discussed below, if you are a U.S. holder and you sell or otherwise dispose of your shares or ADSs, you will
recognize capital gain or loss for United States federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you realize and your tax basis, determined in U.S. dollars, in your shares or ADSs. Capital gain of
a noncorporate U.S. holder that is recognized in taxable years beginning before January 1, 2011 will generally be taxed at a maximum rate of 15% where the holder has a holding period greater than one year. Capital gain of a noncorporate U.S.
holder that is recognized in taxable years beginning after December 31, 2010 will generally be taxed at a maximum rate of 20% where the holder has a holding period greater than one year. The deductibility of capital losses is subject to
limitations under the Code. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes.

PFIC Rules

Nidec
believes that its shares and ADSs should not be treated as stock of a PFIC for United States federal income tax purposes, but this conclusion is a factual determination that is made annually and thus may be subject to change. If Nidec were to be
treated as a PFIC, unless a U.S. holder elects to be taxed annually on a mark-to-market basis with respect to the shares or ADSs, gain realized on the sale or other disposition of your shares or ADSs would in general not be treated as capital gain.
Instead, if you are a U.S. holder, you would be treated as if you had realized such gain and certain excess distributions ratably over your holding period for the shares or ADSs and would be taxed at the highest tax rate in effect for
each such year to which the gain was allocated, together with an interest charge in respect of the tax attributable, through December 31, 2010, to each such year. With certain exceptions, your shares or ADSs will be treated as stock in a PFIC
if Nidec were a PFIC at any time during your holding period in your shares or ADSs. Dividends that you receive from Nidec will not be eligible for the special tax rates applicable to qualified dividend income if Nidec is treated as a PFIC with
respect to you either in the taxable year of the distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends paid to you in respect of shares or ADSs and the proceeds received by you from
the sale, exchange or other disposition of shares or ADSs within the United States unless you are a corporation or other exempt recipient. A backup withholding tax may apply to such payments if you fail to provide a taxpayer identification number or
certification of exempt status or fail to report in full dividend and interest income.

Backup withholding is not an
additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against your U.S. federal income tax liability, provided that the required information is furnished to the IRS.

Japanese Taxation

The
following is a summary of the principal Japanese tax consequences to owners of our shares who are non-resident individuals or non-Japanese corporations without a permanent establishment in Japan to which the relevant income is attributable. The
changes are subject to changes in the applicable Japanese laws or double taxation conventions occurring after that date. This summary is not exhaustive of all possible tax considerations which may apply to a particular investor. Potential investors
should satisfy themselves as to:



| |  |  | the overall tax consequences of the acquisition, ownership and disposition of shares or ADSs, including specifically the tax consequences under
Japanese law;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the laws of the jurisdiction of which they are resident; and

| |  |  | any tax treaty between Japan and their country of residence, by consulting their own tax advisers.
| | - |  | --------------------------------------------------------------------------------------------------

Generally, a non-resident shareholder is subject to Japanese withholding tax on dividends on the shares paid by us. A stock split is not
subject to Japanese income or corporation tax, as it is characterized merely as an increase of number of shares (as oppose to an increase of value of shares) from Japanese tax perspectives. A conversion of retained earnings or legal reserve (but
other than additional paid-in capital, in general) into stated capital on a non-consolidated basis is not characterized as a deemed dividend for Japanese tax purposes, and therefore such a conversion does not trigger Japanese withholding taxation
(Article 2(16) of the Japanese Corporation Tax Law and Article 8(1)(xiv) of the Japanese Corporation Tax Law Enforcement Order).

If we purchase our listed shares by way of a tender offer for the purpose of cancellation with retained earnings, the selling
shareholders (both individuals and corporations) are in general required to recognize (i) a deemed dividend corresponding to a price into share capital portion (including additional paid-in capital) and retained earnings portion on a
non-consolidated basis under Article 24(1)(iv) of the Japanese Corporation Tax Law, and (ii) capital gain or loss computed as a difference between the basis of the shares subject to the tender offer at the shareholders level and the
amount of the consideration for the tender offer (deducting the amount corresponding to the deemed dividend computed as (i) above) under Article 61-2(1)(i) of the same law. On the other hand, no deemed dividend is required to be recognized if
we purchase our shares at/through the stock market due to the difficulty of identifying each shareholder sold our shares (Article 24(1)(iv) of the Japanese Corporation Tax Law and Article 23(1)(iv) of the Japanese Corporation Tax Law Enforcement
Order). When shares are acquired by us (whether by way of a tender offer or otherwise) for the purpose of cancellation with retained earnings, the shareholders (both individuals and corporations) whose shares were not canceled are not subject to the
deemed dividend taxation.

Unless otherwise provided for in applicable tax treaties, conventions or agreements reducing the
maximum rate of withholding tax, under Japanese taxation law, the withholding rate applicable to dividends on the listed shares such as those paid by us to non-resident shareholders is currently 7% which is applicable during the period from
January 1, 2004 through December 31, 2011 (2009 tax legislation extended this period). 15% withholding rate will apply thereafter. Notwithstanding the 7% or 15% withholding rate periods above, 20% withholding rate applies to dividends paid
to any individual shareholder who holds 5% or more of the outstanding shares (Please refer to Article 182(2) of the Japanese Income Tax Law and Article 9-3(1) and (2) of the Japanese Special Tax Measures Law for these withholding rates). Japan
has income tax treaties, conventions or agreements whereby the above mentioned withholding tax rate is generally promulgated as 15% for portfolio investors with, among others, Australia, Belgium, Canada, Denmark, Finland, Germany, Ireland, Italy,
Luxembourg, The Netherlands, New Zealand, Norway, Singapore, Spain, Sweden and Switzerland. Under the tax treaty between the United States and Japan (the Treaty) of which withholding tax treatments is applicable effective from
July 1, 2004, the withholding tax rate on dividends (those declared on or after July 1, 2004) is 10% for portfolio investors, if they do not have a permanent establishment in Japan and the shares with respect to which such dividends are
paid are not related in-fact to such permanent establishment, and if they are qualified US residents eligible to enjoy treaty benefits. It shall be noted that, under the Treaty, withholding tax on dividends declared after July 1, 2004 is exempt
from Japanese taxation by way of withholding or otherwise for pension funds which are qualified US residents eligible to enjoy treaty benefits unless such dividends are derived from the carrying on of a business, directly or indirectly, by such
pension funds. The similar changes are made to the tax treaty between the United Kingdom and Japan which is applicable to dividends declared on or after January 1, 2007 due to the renewal of the tax treaty. The tax treaty between France and
Japan was also renewed effective from January 1, 2008 under which the standard treaty withholding rate for portfolio investors on dividends was reduced from 15% to 10%. In addition, the tax treaty between Australia and Japan was also renewed
and 10% standard treaty withholding rate for portfolio investors on dividends is applicable to dividends declared on or after January 1, 2009. Furthermore, renewal of two tax treaties is currently scheduled (the one between the Netherlands and
Japan, and the one between Switzerland and Japan) under which the standard treaty withholding rate for portfolio investors on dividends will be

reduced from 15% to 10%. Non-resident shareholders who are entitled to a reduced rate of Japanese
withholding tax on payment by us of dividends on the shares are required to submit an Application Form for Income Tax Convention regarding Relief from Japanese Income Tax on Dividends in advance through us to the relevant tax authority before
payment of dividends. A standing proxy for non-resident shareholders may provide such application service. See Item 10.B. of this annual report. Non-resident shareholders who do not submit an application in advance will be entitled to claim the
refund of withholding taxes withheld in excess of the rate of an applicable tax treaty from the relevant Japanese tax authority. For Japanese tax purposes, the treaty rate normally applies superseding the tax rate under the domestic law. However,
due to the so-called preservation doctrine under Article 1(2) of the Treaty, and/or under Article 3-2 of the Special Measures Law for the Income Tax Law, Corporation Tax Law and Local Taxes Law with respect to the Implementation of Tax Treaties, if
the tax rate under the domestic tax law is lower than that promulgated under the applicable income tax treaty, then the domestic tax rate is still applicable. If the domestic tax rate still applies, no treaty application is required to be filed,
consequently.

Gains derived from the sale of shares outside Japan, or from the sale of shares within Japan by a nonresident
shareholder as a portfolio investor, are generally not subject to Japanese income or corporation taxes.

Japanese inheritance
and gift taxes may be assessed against an individual who has acquired shares as a legatee, heir or donee, even if the individual is not a Japanese resident.

Item 11. Quantitative and Qualitative Disclosure About Market Risk.

We hold financial instruments in the normal course of business and are exposed to market risk, including changes in foreign
exchange rates, interest rates and equity prices. We employ a variety of measures to manage market risk related to our financial instruments, including cash and cash equivalents, financial receivables, securities investments, long-term debt and
short-term borrowings.

We do not have a policy of hedging all or a defined portion of specific risks. Accordingly, our
decisions with regard to the use of derivative instruments are made on a case-by-case basis, and the nature and quantity of open derivative contracts can vary significantly over time. However, from time to time, we enter into derivative financial
instruments which include foreign exchange forward contracts and interest rate swap agreements. Foreign exchange forward contracts are designed to reduce our exposure to losses resulting from adverse fluctuations in foreign exchange rates on our
foreign currency accounts receivables, other receivables and accounts payable. Interest rate swaps are designed to reduce our exposure to losses resulting from adverse fluctuations in interest rates on the underlying financial instruments.

Foreign currency exchange rate risk

Transaction risk

A significant portion of our business is conducted in currencies other than the Japanese yen, most significantly the U.S. dollar. While
sales denominated in U.S. dollars are, to a significant extent, offset by U.S. dollar denominated costs, we generally have had a significant net long U.S. dollar position. To the extent that there are any open foreign currency, which will most
likely be U.S. dollar-denominated positions, we are exposed to the risk of foreign currency fluctuations. Any gains and losses that result are recorded in our results of operations for the relevant period. Foreign exchange gains and losses represent
the differences between the value of monetary assets and liabilities when they are originated at exchange rates when a purchase or sale occurs and their value at the prevailing exchange rate when they are settled or translated at year-end. Foreign
currency-denominated monetary assets may include bank deposits, trade receivables and other receivables and monetary liabilities may include trade and notes payable, borrowings and debt.

Translation risk

Our reporting currency is the Japanese yen. We have assets and liabilities outside Japan that are subject to fluctuations in foreign
currency exchange rates. Our assets and liabilities that are outside Japan are primarily located in Singapore, Thailand, the Philippines and China. We prepare financial statements of our foreign operations in their functional currencies prior to
consolidation in our financial statements. Translation gains and losses arising from changes in the value of the reporting currency relative to the functional currencies of the underlying operations are recorded outside of our statement of
operations in other comprehensive income until we dispose of or liquidate the relevant foreign operation.

Foreign currency risk
management

As our investments in foreign subsidiaries with a functional currency other than the Japanese yen are
generally considered long-term, we do not hedge these investments.

From time to time we utilize foreign currency forward
contracts and foreign currency options derivative instruments to manage exposure to exchange rate volatility for accounts payable, accounts receivable and anticipated transactions denominated in foreign currencies. However, we do not use instruments
with leverage, nor exotic options, to mitigate market risk. Changes in the fair values of our foreign exchange forward contracts and options are recognized as gains and losses on derivative instruments within our results of operations. The table
below sets forth the aggregate contract amounts and weighted-average contracted forward rates for annual maturities of the foreign exchange forward contracts as of March 31, 2010.

Interest rate risk

We have long-term receivables and debt, with fixed and variable rates. We enter into interest rate swaps and other contracts to reduce our
market risk exposure from changes in interest rate and to stabilize the fair values and cash flows of our receivables and debts. Nonetheless, our receivables and debt obligations subject us to market fluctuations in interest rates.

The table below sets forth information about our derivative financial instruments and other financial instruments that are sensitive to
changes in interest rates. For our loan receivables and debts, it indicates whether the interest component is fixed or variable, the amount of the cash flows and the expected weighted-average interest rate for the next five years and thereafter and
the items fair value. For our interest rate currency swaps, the table presents payment type, notional principal amounts and weighted-average interest rates by expected (contracted) maturity dates and the items fair value. Notional
amounts are used to calculate the contractual payments to be exchanged under the contracts.

Equity security price risk

We hold available-for-sale securities and held-to-maturity securities that are included in our marketable securities. At March 31,
2009, the fair value of available-for-sale securities and held-to-maturity securities were ¥12,131 million and ¥201 million, respectively. At March 31, 2010, the fair value of available-for-sale securities and held-to-maturity
securities were ¥16,564 million and ¥200 million, respectively.

If the fair value of available-for-sale
securities were to change by 10%, the impact on the carrying amount of those securities as of March 31, 2010 would be ¥1,656 million.

For further information relating to marketable securities, see Item 5.A. Operating and Financial Review and Prospects 
Operating Results  Application of Critical Accounting Policies  Other-than-temporary Losses on Marketable Securities and Note 10 to our consolidated financial statements included in this annual report.

Fees and Payments made by the Depositary to the Issuer

The Depositary has agreed to reimburse certain reasonable company expenses related to our ADR Program and incurred by us in connection
with the Program, including investor relations expenses and stock exchange application and listing fees. There are limits on the amount of expenses for which the Depositary will reimburse us, but the amount of reimbursement available to us is not
related to the amounts of fees the Depositary collects from investors. Under certain circumstances, including where the ADR Program is terminated prior to December 31, 2011, we are required to repay to the Depositary the amounts reimbursed in
prior periods. For the calendar year ended December 31, 2009, the Depositary has agreed to reimburse an aggregate of US$50,000 to us consisting of US$12,000 of investor relations expenses and US$38,000 of New York Stock Exchange listing fees.

management conducted an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), as of
March 31, 2010. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2010, our disclosure controls and procedures were effective. Our disclosure controls and procedures are
designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and that such
information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Managements Report on Internal Control over Financial Reporting

Our Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined
in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with applicable generally accepted accounting principles.

Because of its inherent
limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management has evaluated
the effectiveness of our internal control over financial reporting based upon criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Based on this assessment, management determined that we maintained effective internal control over financial reporting as of
March 31, 2010.

Our independent registered public accounting firm, Kyoto Audit Corporation, has audited the
effectiveness of our internal control over financial reporting as of March 31, 2010, as stated in their report which appears on page F-2 of this annual report on Form 20-F.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the fiscal year ended March 31, 2010 that has
materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

In
addition, during the year management continued to enhance and improve certain other policies and procedures including developing and providing comprehensive Company-wide training on U.S. securities law applicable to foreign private issuers, enhanced
training related to U.S. GAAP and a comprehensive review of all policies and procedures to add clarity, references and additional alignment with financial reporting standards. As a result, a significant deficiency identified as of March 31,
2009 with respect to the related party loan discussed in Item 7.B. Major Shareholders and Related Party Transactions.  Related Party Transactions.  Loan to S.N. Kohsan above does not exist as of March 31, 2010.

|Item 16A. | Audit Committee Financial Expert.
|--------- | ---------------------------------

Our Board of Corporate Auditors has determined that we do not have an audit committee financial expert as defined in
Item 16A of Form 20-F serving on the Board of Corporate Auditors. Our Board of Directors and Board of Corporate Auditors believe that the combined knowledge, skills and experience of the Board of Corporate Auditors, elected and acting in
accordance with the Company Law of Japan, enables its members, as a group, to act effectively in the fulfillment of their tasks and responsibilities, including those under the Sarbanes-Oxley Act of 2002. In addition, the Corporate Auditors have the
power and authority to engage outside experts as they deem appropriate to provide them with advice on matters related to their responsibilities.



|Item 16B. | Code of Ethics.
|--------- | ---------------

We have
adopted a written code of ethics for our chief executive officer, chief financial officer, chief accounting officer and other senior officers, which was enacted on May 1, 2003 and updated on June 6, 2009. Our code of ethics is attached as
Exhibit 11 to this annual report.

accounting and reporting standards.

Pursuant to Rule 2-01(c)(7) of Regulation S-X, the Board of Corporate Auditors pre-approves
the engagement of our principal accountants and the engagement of the member firms of the PricewaterhouseCoopers network to render audit and non-audit services to us. As a general rule, the Board of Corporate Auditors specifically pre-approves the
engagement of such services after examining the details of the proposal engagement submitted by our management. With respect to certain specified audit and non-audit services, once every year, the Board of Corporate Auditors generally pre-approves
the engagement of our principal accountants and their affiliates to render such services pursuant to the Boards pre-approval policies and procedures. Under the pre-approval policies and procedures, services that are the subject of general
pre-approval are specifically identified, together with the maximum aggregate fee amount that may be paid for each such service. The Board of Corporate Auditors reviews this list of specific services and related matters on an annual basis. All
services to be rendered by our principal accountants or their affiliates that are not specifically identified must be specifically pre-approved by the Board of Corporate Auditors. Even for those services that are specifically identified, the
rendering of such services for fees in excess of the maximum aggregate fee amount under the pre-approval policies and procedures must be specifically pre-approved by the Board of Corporate Auditors.

In the fiscal year ended March 31, 2010, the Board of Corporate Auditors approved some of the services relating to Audit
Related Fees set forth above pursuant to Rule 2-01(c)(7)(i)(C) of Regulation S-X , which services related to less than 0.1% of Total fees.



|Item 16D. | Exemptions from the Listing Standards for Audit Committees.
|--------- | -----------------------------------------------------------

With respect to the requirements of Rule 10A-3 under the U.S. Securities Exchange Act of 1934 relating to listed company audit committees,
which apply to us through Section 303A.06 of the New York Stock Exchanges Listed Company Manual, we rely on the exemption provided by paragraph (c)(3) of that Rule available to foreign private issuers with boards of corporate auditors
meeting certain requirements. For a New York Stock Exchange-listed Japanese company with a Board of Corporate Auditors, the requirements for relying on paragraph (c)(3) of Rule 10A-3 are as follows:



| | (a) | The Board of Corporate Auditors is established, and its members are selected, pursuant to Japanese law expressly requiring such a board for Japanese companies that
elect to have a corporate governance system with corporate auditors.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Japanese law requires the Board of Corporate Auditors to be separate from the board of directors.
| | --- | -------------------------------------------------------------------------------------------------



| | (c) | None of the members of the Board of Corporate Auditors is elected by management, and none of the listed companys executive officers is a member of the Board of
Corporate Auditors.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Japanese law sets forth standards for the independence of the members of the Board of Corporate Auditors from the listed company or its management.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | The Board of Corporate Auditors, in accordance with Japanese law or the listed companys governing documents, is responsible, to the extent permitted by Japanese
law, for the appointment, retention and oversight of the work of any registered public accounting firm engaged (including, to the extent permitted by Japanese law, the resolution of disagreements between management and the auditor regarding
financial reporting) for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the listed company, including its principal accountant which audits its consolidated financial statements included
in its annual reports on Form 20-F.

| | (f) | To the extent permitted by Japanese law:
| | --- | ----------------------------------------



| | - |  | the Board of Corporate Auditors establishes procedures for (i) the receipt, retention and treatment of complaints received by the listed company
regarding accounting, internal accounting controls, or auditing matters, and (ii) the confidential, anonymous submission by the listed companys employees of concerns regarding questionable accounting or auditing matters;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - |  | the Board of Corporate Auditors has the authority to engage independent counsel and other advisers, as it determines necessary to carry out its duties;
and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| | - |  | the listed company provides for appropriate funding, as determined by its Board of Corporate Auditors, for payment of (i) compensation to any
registered public accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the listed company, (ii) compensation to any advisers employed by the Board of Corporate
Auditors, and (iii) ordinary administrative expenses of the Board of Corporate Auditors that are necessary or appropriate in carrying out its duties.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In our assessment, our Board of Corporate Auditors meets the requirements for reliance on the exemption in paragraph (c)(3) of Rule 10A-3
described above and is not materially less effective than an audit committee meeting all the requirements of paragraph (b) of Rule 10A-3 (without relying on any exemption provided by that Rule) in acting independently of management and
performing the functions of an audit committee as contemplated the Rule.

|Item 16G. | Corporate Governance.
|--------- | ---------------------

Companies listed on the New York Stock Exchange, or the NYSE, must comply with certain listing standards regarding corporate
governance under the NYSEs Listed Company Manual, or the NYSE Corporate Governance Standards. Listed companies that are foreign private issuers, such as us, however, are permitted, with certain exceptions, to follow home country
practices in lieu of the NYSE Corporate Governance Standards. Our corporate governance practices, which comply with Japanese laws, regulations and stock exchange rules, and the NYSE Corporate Governance Standards followed by U.S. listed companies
have the following significant differences:

Director Independence

A company listed on the NYSE must have a majority of directors that meet the independent requirements under Section 303A of the
NYSEs Listed Company Manual. The Company Law (Law No.86, 2005) of Japan, or the Company Law, does not require Japanese companies with boards of corporate auditors, such as us, to have a director who is independent as defined in the
NYSE Corporate Governance Standards, on their boards of directors.

Audit Committee

A company listed on the NYSE must have an audit committee composed entirely of independent directors. We are generally exempted, with some
exceptions, from this requirement by virtue of paragraph (c)(3) of Rule 10A-3 of the U.S. Securities Exchange Act of 1934 as amended.

Consistent with the requirements of the Company Law, our corporate auditors are elected by a resolution at a general meeting of
shareholders. We currently have five corporate auditors, which exceeds the minimum of three corporate auditors required by the Company Law, who comprise our board of corporate auditors. Our board of corporate auditors has a statutory duty to
monitor, review and report on the administration of our affairs and accounts for the benefit of our shareholders.

The Company
Law requires that at least half of a companys corporate auditors be outside auditors, which is defined as a corporate auditor who has not been a director, executive officer, manager or employee of the company or any of its
subsidiaries at any time prior to his or her election. Four of our five current corporate auditors are outside corporate auditors.

Compensation, Nominating and Corporate Governance Committees

A company listed on the NYSE must have a compensation committee comprised entirely of independent directors. Under the Company Law, we and
other Japanese companies with boards of corporate auditors, are not required to establish a compensation committee. The Company Law requires that the total amount of remuneration to be paid to all directors and the total amount of remuneration to be
paid to all corporate auditors must be approved by a resolution of the general meeting of shareholders, unless their remuneration is provided for in the articles of incorporation. The distribution of remuneration among directors is broadly delegated
to the board of directors, and distribution of remuneration among corporate auditors is determined by consultation among the corporate auditors.

A company listed on the NYSE must also have a nominating or corporate governance committee comprised entirely of independent directors.
Under the Company Law, we and other Japanese companies with boards of corporate auditors are not required to establish a nominating or corporate governance committee. Pursuant to the Company Law, our board of directors nominates and submits a
proposal for election of directors for shareholder approval. Our shareholders elect or dismiss directors by a simple majority of votes at a general meeting of shareholders. Our corporate auditors are also elected or dismissed at a general meeting of
shareholders. A proposal by our board of directors to elect a corporate auditor needs the consent of our board of corporate auditors.

Corporate Governance Guidelines

A company listed on the NYSE must adopt and disclose corporate governance guidelines. Under the Financial Instruments and Exchange Law of
Japan and applicable stock exchange rules, we are not required to adopt or disclose corporate governance guidelines. However, we are required to disclose policies and the present status of our corporate governance under the Financial Instruments and
Exchange Law of Japan in respect of timely disclosure.

Code of Business Conduct and Ethics

A company listed on the NYSE must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and
promptly disclose any waivers of the code for directors and executive officers. Under the Company Law, the Financial Instruments and Exchange Law of Japan and applicable stock exchange rules, we are not required to adopt or disclose such code of
business conduct and ethics. However, we maintain and disclose as an exhibit to our annual report on Form 20-F the relevant sections of, a Nidec Code of Ethics, which we believe is consistent with the code of ethics described under
Section 406 of the U.S. Sarbanes-Oxley Act of 2002.

Shareholder Approval of Equity-Compensation Plans

A company listed on the NYSE must obtain shareholder approval for an equity compensation plan. Under the Company Law, a public company
seeking to issue rights to acquire from the company shares of its stock at a prescribed price, or stock acquisition rights, must obtain the approval of its board of directors.

Under the Company Law, if a company desires to adopt an equity-compensation plan in which stock acquisition rights are granted on
specially favorable terms to the plans recipients, then the company must obtain shareholder approval by a special resolution of a general meeting of shareholders, where the quorum is one-third of the total number of voting rights
and the approval of at least two-thirds of the voting rights represented at the meeting is required.

Executive Sessions

A company listed on the NYSE must hold regularly scheduled executive sessions where participants are limited to non-management directors.
Under the Company Law, Japanese corporations are not required to hold such executive sessions.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of

Nihon Densan Kabushiki Kaisha

(NIDEC
Corporation):

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of
income, changes in equity, and cash flows present fairly, in all material respects, the financial position of NIDEC Corporation and its subsidiaries at March 31, 2010 and 2009, and the results of their operations and their cash flows for each
of the three years in the period ended March 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control
over financial reporting as of March 31, 2010, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Companys management is
responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Managements Report on
Internal Control over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial reporting based on our integrated audits. We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements
are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.
Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As described in Note 2 to the consolidated financial statements, NIDEC Corporation retrospectively adopted the FASB Accounting Standards
Codification (ASC) 810, Consolidation on April 1, 2009 and prepared the consolidated financial statements based upon this accounting standard.

##### Table of Contents

A companys internal control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial
reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could
have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

NIDEC CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of operations:

NIDEC Corporation (the Company) and its subsidiaries (collectively NIDEC) are primarily engaged in the design,
development, manufacture and marketing of i) small precision motors, which include spindle motors for hard disk drives, motors for optical disk drives, small precision fans and other small motors; ii) mid-size motors, which are used in automobiles,
various electric household appliances and industrial equipment; iii) machinery, which includes, test systems, measuring equipment, power transmission equipment, factory automation systems, card readers and industrial robots; iv) electronic and
optical components, which include camera shutters, camera lens units, switches, trimmer potentiometers, motor driven actuator units, processing and precision plastic mold products; and v) other products, which include auto parts, pivot assemblies,
other components and other services. Manufacturing operations are located primarily in Japan and Asia (China, Thailand, the Philippines, Vietnam and Singapore), and sales subsidiaries are primarily located in Asia, Europe and North America.

The main customers for spindle motors are manufacturers of hard disk drives. NIDEC also sells its products to the
manufacturers of various automation equipment, electric household appliances, home video game consoles, telecommunication and audio-visual equipment, and automotive components.

2. Summary of significant accounting policies:

The Company and its subsidiaries in Japan maintain their records and prepare their financial statements in accordance with accounting
principles generally accepted in Japan, and its foreign subsidiaries in conformity with those of their countries of domicile. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to
conform with accounting principles generally accepted in the United States of America. Significant accounting policies after reflecting adjustments for the above are as follows:

Estimates

The preparation of NIDECs consolidated financial statements in conformity with accounting principles generally accepted in the
United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and contingent assets and liabilities at the date of the financial statements, as well as the reported amounts
of revenues and expenses during the reporting period. Some of the more significant estimates include the allowance for doubtful accounts, depreciation and amortization of long-lived assets, valuation allowance for deferred tax assets, fair value of
financial instruments, uncertain tax positions, pension liabilities and the recoverability of long-lived assets and goodwill. Actual results could differ from those estimates.

Basis of consolidation and accounting for investments in affiliated companies

The consolidated financial statements include the accounts of the Company and those of its majority-owned subsidiary
companies. All significant intercompany transactions and accounts have been eliminated. Companies over which NIDEC exercises significant influence, but which it does not control, are classified as affiliated companies and accounted for using the
equity method. Consolidated net income includes NIDECs equity in current earnings (losses) of such companies, after elimination of unrealized intercompany profits.

On occasion, NIDEC may acquire additional shares of the voting rights of a consolidated subsidiary or dispose of a part of those shares
or a Nidec consolidated subsidiary may issue its shares to third parties. With respect to such transactions, all transactions for changes in a parents ownership interest in a subsidiary that do not result in the subsidiary ceasing to be a
subsidiary are recognized as equity transactions.

The FASB Accounting Standards Codification (ASC) 810,
Consolidation (formerly the FASB Interpretation No.46R, Consolidation of Variable Interest Entitiesan interpretation of ARB No.51) requires the consolidation or disclosure of variable interest entities. During the year
ended March 31, 2009, an entity was identified as a variable interest entity in accordance with ASC 810, but NIDEC was not the primary beneficiary and therefore did not consolidate the entity. During the year ended March 31, 2010, NIDEC
does not hold any variable interests in a variable interest entity.

Translation of foreign currencies

Non monetary asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at the year-end exchange
rates and all income and expense accounts are translated at exchange rates that approximate those prevailing at the time of the transactions. The resulting translation adjustments are included as a component of accumulated other comprehensive income
in shareholders equity.

Monetary assets and liabilities denominated in foreign currencies are translated at the
year-end exchange rates and the resulting transaction gains or losses are taken into income.

Cash and cash equivalents

Cash and cash equivalents include all highly liquid investments, with original maturities of three months or less that are
readily convertible to known amounts of cash and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined principally on the weighted average cost basis. Cost includes
the cost of materials, labor and applied factory overhead. Projects in progress, which mainly relate to production of factory automation equipment based on contracts with customers, are stated at the lower of cost or market, cost being determined as
the accumulated production cost.

Marketable securities

Marketable securities consist of equity securities that are listed on recognized stock exchanges and debt securities. Equity securities
designated as available-for-sale are carried at fair value with changes in unrealized gains or losses included as a component of accumulated other comprehensive income in shareholders equity, net of applicable taxes. Realized gains and losses
are determined on the average cost method and are reflected in the statement of income. Other than temporary declines in market value of individual securities classified as available-for-sale are charged to income in the period the loss occurs. Debt
securities designated as held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts.

Derivative financial instruments

NIDEC employs derivative financial instruments, including interest rate swaps, interest rate currency swaps, and foreign exchange forward
contracts to manage its exposure to fluctuations in foreign currency exchange rates and interest rates. Derivative contracts are marked to market and changes in value, both increases and decreases, are recognized directly in the consolidated
statement of income. There are no derivatives designated as hedges or accounted for as hedges under ASC 815, Derivatives and Hedging (formerly SFAS No.133, Accounting for Derivative Instruments and Hedging Activities).

Property, plant and equipment

Property, plant and equipment are stated at cost. Major renewals and improvements are capitalized; minor replacements, maintenance and
repairs are charged to current operations. Depreciation of property, plant and equipment is mainly computed on the declining-balance method to reflect the manner in which the machinery is used due to short product cycles and rapid technology changes
by the Company and its Japanese subsidiaries, and on the straight-line method for foreign subsidiary companies at rates based on the estimated useful lives of the assets. Estimated useful lives range from 10 to 20 years for most spindle motor
factories, from 7 to 47 years for factories to produce other products, 50 years for the head office and sales offices, from 2 to 22 years for leasehold improvements, and from 2 to 15 years for machinery and equipment.

Depreciation expense amounted to ¥36,334 million, ¥32,147 million, and ¥29,185 million ($313,682 thousand) for
the years ended March 31, 2008, 2009, and 2010, respectively.

Lease

NIDEC capitalizes certain leases and related obligations when any of the four criteria are met within the guidance of ASC 840,
Leases (formerly, SFAS No.13 Accounting for Leases. Under ASC840, these leases and related obligations are capitalized at the commencement of the lease at the lower of the fair value of the leased property and the present
value of the minimum lease payments.

Goodwill

Goodwill represents the excess of the aggregate of: (1) the consideration transferred measured by acquisition-date fair value;
(2) the fair value of any noncontrolling interest in the acquiree; and (3) in a business combination achieved in stages, the acquisition-date fair value of the acquirers previously held equity interest in the acquiree, over the net
of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. Under ASC 350 IntangiblesGoodwill and Other (formerly SFAS No.142 Goodwill and Other Intangible Assets), goodwill acquired
in business combinations is not amortized but tested annually for impairment. NIDEC tests for impairment at the reporting unit level on January 1st of each year. In addition, NIDEC tests for impairment between annual tests if an event occurs or
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This test is a two-step process. The first step of the goodwill impairment test, used to identify potential impairment,
compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value, which is based on discounted future cash flows, exceeds the carrying amount, goodwill is not considered impaired. If the carrying amount
exceeds the fair value, the second step must be performed to measure the amount of the impairment loss, if any. The second step compares the implied fair value of the reporting units goodwill with the carrying amount of that goodwill.

Long-lived assets

NIDEC reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an
asset group may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset group exceeds the estimated undiscounted future cash flows expected to result from the use of the asset group and its eventual
disposition. The amount of the impairment loss to be recorded is calculated as the excess of the assets groups carrying value over its fair value. Long-lived assets that are to be disposed of other than by sale are considered to be held and
used until the disposal. Long-lived assets that are to be disposed of by sale are reported at the lower of their carrying value or fair value less costs to sell. Reductions in carrying value are recognized in the period in which long-lived assets
are classified as held for sale.

Revenue recognition

NIDEC recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or
determinable and collectibility is reasonably assured. For small precision motors, mid-size motors and electronic and optical components, these criteria are generally met at the time a product is delivered to the customers site which is the
time the customer has taken title to the product and the risk and rewards of ownership have been substantively transferred. These conditions are met at the time of delivery to customers in domestic sales (FOB destination) and at the time of shipment
for export sales (FOB shipping point). Revenue for machinery sales is recognized upon receipt of final customer acceptance. At the time the related revenue is recognized, NIDEC makes provisions for estimated product returns.

Research and development expenses

Research and development expenses, mainly consisting of personnel and depreciation expenses at research and development branches, are
charged to operations as incurred.

Advertising costs

Advertising and sales promotion costs are expensed as incurred. Advertising costs were ¥372 million, ¥300 million, and
¥156 million ($1,677 thousand) for the years ended March 31, 2008, 2009 and 2010, respectively.

Income taxes

The provision for income taxes is computed based on the pretax income included in the consolidated statement of
income. The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred
tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are recorded to reduce deferred tax
assets when it is more likely than not that a tax benefit will not be realized.

NIDEC recognizes the financial statement
effects of tax positions when it is more likely than not, based on the technical merits, that the tax positions will be sustained upon examination by the tax authorities. Benefits from tax positions that meet the more-likely-than-not recognition
threshold are measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. Interest and penalties accrued related to unrecognized tax benefits are included in other, net in the consolidated
statements of income.

Earnings per share

Basic net income per common share is calculated by dividing net income by the weighted-average number of shares outstanding during the
reported period. The calculation of diluted net income per common share is similar to the calculation of basic net income per share, except that the weighted-average number of shares outstanding includes the additional dilution from potential common
stock equivalents such as convertible bonds and options.

Other comprehensive income

NIDECs other comprehensive income is primarily comprised of unrealized gains and losses on marketable securities designated as
available-for-sale, foreign currency translation adjustments and adjustments to recognize pension liabilities associated with NIDECs defined benefit pension plans.

Reclassification

Certain reclassifications of previously reported amounts have been made to the consolidated statements of balance sheets, income and cash
flows for the years ended March 31, 2008 and 2009 to conform to the current year presentation.

As of December 31, 2008, NIDEC discontinued its optical pickup unit
(OPU) business. The results of the OPU business were previously recorded in the NSNK and All Others reporting segments. In addition, as of September 30, 2009, NIDEC discontinued its semiconductor manufacturing equipment business.
The results of the semiconductor manufacturing equipment business were previously recorded in the NTSC and All Others reporting segments. The operating results of the discontinued businesses and exit costs with related taxes were recorded as
loss on discontinued operations in the consolidated statement of income in accordance with ASC 205-20, Presentation of Financial Statements-Discontinued Operations (formerly SFAS No.144, Accounting for the impairment or
disposal of Long-Lived Assets.).

Accounting Changes

As of September 15, 2009, NIDEC adopted the FASB Accounting Standards Codification (ASC) 105, Generally Accepted
Accounting Principles (formerly Statement of Financial Accounting Standards (SFAS) No. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principlesa replacement of FASB
Statement No. 162). ASC 105 replaces SFAS No. 162 the Hierarchy of Generally Accepted Accounting Principles and establishes the FASB Accounting Standards Codification as the single source of authoritative
nongovernmental U.S. Generally Accepted Accounting Principles (other than guidance issued by the SEC). The adoption of ASC 105 had no impact on NIDECs consolidated financial position, results of operations or liquidity.

As of April 1, 2009, NIDEC adopted ASC 820, Fair Value Measurements and Disclosures (formerly SFAS No. 157,
Fair Value Measurements) for certain nonfinancial assets and liabilities. FASB Staff Position (FSP) No. FAS 157-2, Effective Date of FASB Statement No. 157 delays the effective date of ASC 820 for one year for
nonfinancial assets and liabilities. The adoption of ASC 820 did not have a material impact on NIDECs consolidated financial position, results of operations or liquidity.

As of April 1, 2009, NIDEC adopted ASC 805, Business Combinations
(formerly SFAS No. 141 (revised 2007), Business Combinations). ASC 805 requires that assets acquired, liabilities assumed, contractual contingencies, and contingent consideration be measured at fair value as of the acquisition date,
that acquisition-related costs be expensed as incurred, that restructuring costs generally be expensed in periods subsequent to the acquisition date, and the changes in accounting for deferred tax asset valuation allowances and acquired income tax
uncertainties after the measurement period impact income tax expense. The adoption of ASC 805 did not have a material impact on NIDECs consolidated financial position, results of operations or liquidity since NIDEC did not acquire any material
businesses for the year ended March 31, 2010. Any future impact, however, will depend on the number, size and nature of any business combination transactions that we may complete.

As of April 1, 2009, NIDEC adopted ASC 810, Consolidation (formerly SFAS No. 160, Noncontrolling Interests in
Consolidated Financial Statementsan amendment of ARB No. 51). ASC 810 recharacterizes minority interests in a subsidiary as non-controlling interests and requires the presentation of noncontrolling interests as equity in
consolidated balance sheets, and separate identification and presentation in consolidated statements of income of net income attributable to the entity and the noncontrolling interest. ASC 810 also requires all transactions for changes in a
parents ownership interest in a subsidiary that do not result in the subsidiary ceasing to be a subsidiary to be recognized as equity transactions. Upon adoption, noncontrolling interests, which were previously referred to as minority
interests and classified in the mezzanine section between liabilities and equity on the consolidated balance sheets, are now included as a separate component of total equity. Consolidated net income on the consolidated statements of income now
includes the net income (loss) attributable to noncontrolling interests. In addition, payments for additional investments in subsidiaries, which were previously classified in the cash flows from investing activities on the consolidated statements of
cash flows, are now included in cash flows from financing activities. Prior period amounts were reclassified to conform to the current period presentation.

As of June 15, 2009, NIDEC adopted ASC 855, Subsequent Events (formerly SFAS No. 165, Subsequent
Events). ASC 855 establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. The adoption of ASC 855 did not have a
material impact on NIDECs consolidated financial position, results of operations or liquidity.

As of December 15,
2009, NIDEC adopted ASC 715, CompensationRetirement Benefits, (formerly FSP No. FAS 132(R)-1, Employers Disclosures about Postretirement Benefit Plan Assets). ASC 715 provides guidance on employers
disclosures of a defined benefit pension or other postretirement plan. Specifically, employers are required to disclose information about fair value measurements of plan assets. The adoption of ASC 715 did not have a material impact on Nidecs
consolidated financial position, results of operations or liquidity.

Recent Accounting Pronouncements to be adopted in future periods

In December 2009, the FASB issued Accounting Standards Update (ASU) No. 2009-16, Accounting for Transfers of Financial
Assets. This accounting standard codified SFAS No.166, Accounting for Transfers of Financial Assetsan amendment of FASB Statement No. 140. ASU 2009-16 requires more information about transfers of financial assets,
including securitization transactions, and where companies have continuing exposure to the risks related to transferred financial assets. ASU 2009-16 also eliminates the concept of a qualifying special-purpose entity, changes the
requirements for derecognizing financial assets. ASU 2009-16 is effective as of the beginning of each reporting entitys first annual reporting period that begins after November 15, 2009, for interim periods within that first annual
reporting period, and for interim and annual reporting periods thereafter. The adoption of ASU 2009-16 is not expected to have a material impact on its consolidated financial position, results of operations and liquidity.

In December 2009, the FASB issued ASU No. 2009-17, Improvements to Financial Reporting by Enterprises Involved with Variable
Interest Entities. This accounting standard codified SFAS No. 167, Amendments to FASB Interpretation No. 46(R). ASU 2009-17 requires an enterprise to perform an analysis to identify the primary beneficiary of all variable
interest entities and also requires ongoing reassessments of whether an enterprise is the primary beneficiary of all variable interest entities. ASU 2009-17 is effective as of the beginning of each reporting entitys first annual reporting
period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. The adoption of ASU 2009-17 is not expected to have a material impact on its
consolidated financial position, results of operations and liquidity.

4. Acquisitions and dispositions:

On April 27, 2007, NIDEC acquired 18,203,000 shares (or, 51.7%) of the common stock in Japan Servo Co., Ltd. (JSRV),
currently Nidec Servo Corporation (NSRV), which manufactures and sells motors and motor applied products. Since NIDEC already owned 1,466 shares of NSRVs common stock prior to April 27, 2007, total shares and purchase price
for NSRV were 18,204,466 and ¥4,810 million, respectively. NIDEC recognized goodwill amounting to ¥572 million as a result of this acquisition. During the period between April 27, 2007 and March 31, 2008, NIDEC acquired an
additional 3,288,000 shares of NSRVs common stock, increasing its ownership interest in NSRV to 61.1%. As a result, the number of shares of NSRVs common stock held by NIDEC totaled 21,492,466, representing a ¥6,611 million purchase
price in total, and recognized, goodwill of ¥1,610 million as of March 31, 2008.

On June 13, 2008, NIDEC
acquired all of the voting rights of Shanghai Nidec Automotive Electric Motors Limited. This acquisition did not have a material impact on NIDECs consolidated financial position, results of operations or liquidity. In addition, on
August 1, 2008, NIDEC acquired an additional 3,500 new shares of Copal Yamada Corporation. NIDEC had already owned 3,000 shares of Copal Yamada Corporation prior to August 1, 2008. As a result, the number of shares of Copal Yamada
Corporations common shares held by NIDEC became 68.4%. This acquisition did not have a material impact on NIDECs consolidated financial position, results of operations or liquidity.

On March 31, 2009, NIDEC disposed all of the shares of Nidec Nemicon Corporation, its subsidiary. This disposition did not have a
material impact on NIDECs consolidated financial position, results of operations or liquidity.

For all of the above
acquisitions, consummated prior to March 1, 2009, the total cost of these acquisitions has been allocated to the assets acquired and the liabilities assumed based on their respective fair values at the date of the acquisitions in accordance
with SFAS 141, Business Combinations.

On August 4, 2009, NIDEC acquired the additional 60.0% of the voting
rights of NTN-Nidec (Zhejiang) Corporation, currently Nidec Bearing (Zhejiang) Corporation (NBCC), and NTN-Nidec (Thailand) Co., Ltd., currently Nidec Bearing (Thailand) Co., Ltd. (NBTC). NIDEC previously owned 40.0% of the
voting rights of NBCC and NBTC prior to August 4, 2009. As a result, NIDEC acquired all of the voting rights of NBCC and NBTC. These acquisitions did not have a material impact on NIDECs consolidated financial position, results of
operations or liquidity.

On January 26, 2010, NIDEC acquired all of the voting rights of the household motor business of
Appliances Components Companies S.p.A.. As a result, NIDEC has included Nidec Sole Motor Corporation S.R.L. (NSMC) in its scope of consolidation as wholly owned subsidiary of NIDEC. This acquisition did not have a material impact on
NIDECs consolidated financial position, results of operations or liquidity.

On February 26, 2010, NIDEC acquired 864,000 shares (or, 90.0%) of SC WADO Co.,
Ltd. This acquisition did not have a material impact on NIDECs consolidated financial position, results of operations or liquidity.

ASC 805, Business Combinations (formerly SFAS No. 141 (revised 2007), Business Combinations) requires that
assets acquired and liabilities assumed be measured at fair value as of the acquisition date.

The following represents the
unaudited pro forma results of operations of NIDEC for the year ended March 31, 2008, as if the acquisition of NSRV had occurred on April 1, 2007. The pro forma results for the year ended March 31, 2009 and 2010 are not presented as
the adjustments are not material. The unaudited pro forma results of operations are presented for comparative purposes only and are not necessarily indicative of the results of operations that may occur in the future or that would have occurred had

NIDEC has completed the annual impairment test for
existing goodwill as required by ASC 350 as of January 1, 2010. For the years ended March 31, 2008, 2009 and 2010, NIDEC has determined that the fair value of each reporting unit which includes goodwill has been in excess of its carrying
amount. Accordingly, for the years ended March 31, 2008, 2009 and 2010, no goodwill impairment loss has been recorded.

Due to the discontinued OPU business, an impairment loss of ¥357 million of goodwill in All Others segment for the year
ended March 31, 2009 and due to discontinued SME business, an impairment loss of ¥230 million ($2,472 thousand) of goodwill in NTSC (Nidec Tosok Corporation) segment for the year ended March 31, 2010 was recorded as
loss on discontinued operations in the consolidated statement of income in accordance with ASC 205-20 Presentation of Financial Statements-Discontinued Operations (formerly SFAS No.144, Accounting for the impairment or
disposal of Long-Lived Assets).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(continued)



During the years ended March 31, 2008, 2009 and 2010, the net unrealized gain on
available-for-sale securities included as a component of accumulated other comprehensive income, net of applicable taxes, decreased by ¥2,308 million, ¥1,433 million and increased by ¥2,164 million ($23,259 thousand), respectively.

Proceeds from sales of available-for-sale securities were ¥2,221 million, ¥317 million and ¥94 million ($1,010
thousand) for the years ended March 31, 2008, 2009 and 2010, respectively. On those sales, gross realized gains were ¥805 million, ¥241 million and ¥66 million ($709 thousand) and gross realized losses were ¥7 million, ¥4
million and ¥0 million ($0 thousand), respectively.

NIDEC holds long-term investment securities that are classified as
marketable securities and other securities investments. The securities issued by various non-public companies are recorded at cost, as their fair values are not readily determinable. NIDECs management employs a systematic
methodology to assess the recoverability of such investments by reviewing the financial position of the underlying companies and the prevailing market conditions in which these companies operate to determine if NIDECs investment in each
individual company is impaired and whether the impairment is other-than-temporary. If any impairment is determined to be other-than-temporary, the cost of the investment is written-down by the impaired amount and the amount is recognized currently
as a realized loss.

The following table presents the gross unrealized losses on, and fair value of, NIDECs investment
securities, aggregated by investment category and length of time that individual investment securities have been in a continuous unrealized loss position.

NIDEC presumes a decline in value of investment
securities is impaired if the fair value is below the original cost. Among the impaired investment securities, NIDEC presumes a decline in value of equity securities is other-than-temporary if the fair value is 20% or more below the original cost
for an extended period of time. The presumption of an other-than-temporary impairment may be overcome if there is evidence to support that the decline is temporary in nature due to the existence of other factors which overcome the duration or
magnitude of the decline. On the other hand, even if a decline is less than 20%, there may be cases where impairment losses are recognized when specific factors indicate the decline in the fair value is other-than-temporary. As of March 31,
2010, NIDEC determined that the decline in value for equity securities with unrealized losses shown in the above table is temporary in nature.

For the years ended March 31, 2009 and 2010, held-to-maturity securities of ¥201 million and ¥200 million ($2,150
thousand) were pledged as collateral for the deferred payments of certain taxes based on the Japanese Custom Act and Consumption Tax Law, respectively.

15. Pension and severance plans:

The Company and certain subsidiaries sponsor pension and retirement plans, which entitle employees, under most circumstances, to lump-sum
indemnities or pension payments based on current rates of pay and length of service or the number of points. Under normal circumstances, the minimum payment prior to retirement age is an amount based on voluntary retirement. Employees
receive additional benefits upon involuntary retirement, including retirement at the mandatory retirement age.

As of
April 1, 2008, NIDEC adopted the measurement date provision of ASC 715, CompensationRetirement Benefits, (formerly SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement
Plansan amendment of FASB Statements No. 87, 88, 106, and 132(R)). In accordance with this provision, the measurement dates of some of the Japanese benefit pension plans were changed from December 31 to March 31. By the
application of the second approach described in ASC 715-20-65-1, at the beginning of the previous fiscal year, accrued pension and severance costs increased by ¥225 million. Retained earnings, net of tax was reduced by ¥106 million, and
accumulated other comprehensive income, net of tax was reduced by ¥5 million.

March 31, 2011 are ¥73 million ($785 thousand) and ¥115 million ($1,236 thousand), respectively.

Actuarial gain and losses are amortized using the straight-line method over the average remaining service
period of active employees. The estimated net actuarial gain for the defined benefit pension plans that will be amortized from accumulated other comprehensive income into benefits cost for the year ending March 31, 2011 is ¥5 million ($54
thousand).

Japanese plans and foreign plans:

NIDECs policy and objective for plan asset management is to generate a stable return on the investment over the long term, which
enable NIDECs pension funds to meet future benefit payment requirements under risks which NIDEC considers permissible. NIDEC formulates basic portfolio that suits the above-mentioned policy, and ensure that plan assets are
allocated under this basic portfolio. NIDEC evaluates its actual return and revises the basic portfolio, if necessary.

NIDECs portfolio for plans consists of three major components: approximately 12% is invested in equity securities, approximately
11% is invested in debt securities, and approximately 77% is invested in other investment vehicles, primarily consisting of investments in pooled funds and life insurance company general accounts.

The equity securities are selected from stocks that are listed on the securities exchanges. The debt securities are selected from
Japanese and foreign government bonds, public debt instruments, and corporate bonds. Pooled funds included in other assets invest in equity and debt securities in mixture selected from same as above two categories. As for investments in life
insurance company general accounts, the contracts with the insurance companies include a guaranteed interest rate and return of capital.

The three levels of input used to measure fair value are more fully described in Note 21. The fair values of NIDECs pension plan
assets at March 31, 2010, by asset category, are as follows:

Level 1 assets are comprised primarily of cash and cash
equivalents and equity securities, which are valued using an unadjusted quoted market price in active markets with sufficient volume and frequency of transactions. Level 2 assets are comprised primarily of pooled funds that invest in equity and debt
securities, and investments in life insurance company general accounts. Pooled funds are valued at their net asset values that are calculated by the sponsor of the fund and have daily liquidity. The net asset value is based on the fair value of the
underlying assets owned by the fund, minus its liabilities then divided by the number of units outstanding. Investments in life insurance company general accounts are valued at conversion value.

NIDEC expects to contribute approximately ¥997 million ($10,716 thousand) to its defined benefit plans for the year ending

17. Equity:

The Japanese Company Law (the Company Law) provides that an amount equal to 10% of cash dividends from retained earnings by
the Company and its Japanese subsidiaries must be appropriated as a legal reserve. No further appropriations are required when the sum of the legal reserves reaches 25% of stated capital. These reserves currently exceed 25% of stated capital and are
available for dividends under the Company Law subject to approval at the shareholders meeting. Certain foreign subsidiaries are also required to appropriate their earnings to legal reserves under the laws of the respective countries.

The amount of statutory retained earnings of the Company available for dividend payments to shareholders was ¥74,252
million and ¥98,247 million ($1,055,965 thousand) for the years ended March 31, 2009 and 2010, respectively. In accordance with customary practice in Japan, the appropriations are not accrued in the financial statements for the period to
which they relate, but are recorded in the subsequent accounting period. Retained earnings for the year ended March 31, 2010 includes amounts representing final cash dividends of ¥5,572 million ($59,888 thousand), ¥40 ($0.43) per share.

Repurchased treasury stock is not entitled to a dividend under the Company Law. NIDEC resolved to repurchase its own shares
at several meetings of its Board of Directors during the year ended March 31, 2009. In accordance with the resolution, NIDEC repurchased 5,732,600 shares of treasury stock for the aggregate cost of ¥23,758 million. NIDEC owned 5,782,871
shares, or 24,056 million and 5,784,406 shares, or ¥24,067 million ($258,674 thousand) of treasury stock repurchased for the year ended March 31, 2009 and 2010, which were restricted regarding the payment of cash dividend.

Retained earnings relating to equity in undistributed earnings reflect ¥357 million, ¥557 million and ¥197 million ($2,117
thousand) of accumulated deficit of the companies accounted for by the equity method for the years ended March 31, 2008, 2009 and 2010.

NIDEC CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(continued)



NIDEC is subject to a number of different income taxes, which, in the aggregate,
indicate a statutory rate in Japan of approximately 41.0% in 2008, 2009 and 2010. Reconciliation of the differences between the statutory tax rate and the effective income tax rate is as follows:

The effective income tax rate for the year ended March 31, 2010 was lower compared to the effective
income tax rate for the year ended March 31, 2009. The decrease was mainly due to the net impact of a decrease in the impact on the effective tax rate of the valuation allowance and tax benefit in foreign subsidiaries.

With regard to the effective tax rates of the Company and domestic subsidiaries for the year ended March 31, 2009, it approached the
statutory tax rate. The main reason was due to a net impact of an increase in the impact on the effective tax rate of the valuation allowance, decrease in tax on undistributed earnings due to tax law changes and decrease in liabilities for
unrecognized tax benefits for reductions for tax positions of prior year ended March 31, 2008.

The low effective tax
rates of the Company and domestic subsidiaries for the year ended March 31, 2008 were mainly due to the extinguishment of the effect of transfer pricing taxation of the previous period and an increase in the income tax provision by the adoption
of FIN 48.

Tax benefit in foreign subsidiaries primarily relates to income sourced from foreign subsidiaries mainly in
Thailand and the Philippines.

In Thailand, NIDEC received privileges under the promotional certificates issued in May 2005
and December 2006. Under these privileges, NIDEC received an exemption from corporate income tax for a period of five to seven years from the date of commencement of certain revenue-generating activities identified by the promotional certificate.

In the Philippines, NIDEC received certain tax incentives in October 2003, which included an income tax holiday for four
years. In September 2007 the income tax holiday was extended for two years. In September 2009 the income tax holiday was extended for one year. In September 2010 the income tax holiday was extended for one year. In April 2007 NIDEC received another
income tax holiday of a new project for four years. This income tax holiday will be extended more for two years.

Management of NIDEC intends to reinvest certain undistributed earnings of foreign subsidiaries for an
indefinite period of time. As a result, no deferred tax liability has been recorded on undistributed earnings of these subsidiaries, which are not expected to be remitted in the foreseeable future, aggregating ¥105,180 million ($1,130,482
thousand) as of March 31, 2010. NIDEC estimates an additional deferred tax liability of ¥11,018 million ($118,422 thousand) would be required at such time if the full amount of these accumulated earnings were expected to be remitted.

Total amount of unrecognized tax benefits that would reduce the effective tax rate, if recognized, is
¥4,887 million ($52,526 thousand).

Although NIDEC believes its estimates and assumptions of unrecognized tax
benefits are reasonable, uncertainty regarding the final determination of tax audit settlements and any related litigation could affect the effective tax rate in the future periods. Based on each of the items of which NIDEC is aware of at
March 31, 2010, no significant changes to the unrecognized tax benefits are expected within the next twelve months.

NIDEC recognizes interest and penalties related to unrecognized tax benefits as a component of Other, net in the consolidated statements
of income. The interest and penalties for the fiscal year ended March 31, 2008, 2009 and 2010, respectively, had no material impact on its consolidated results of operations. The total gross accrued interest and penalty were ¥107 million
and ¥211 million ($2,268 thousand) at March 31, 2009 and 2010, respectively.

NIDEC remains subject to income tax
examination for the tax returns related to the years beginning on and after January 1, 2003, with various tax jurisdictions including Japan.

NIDEC has no dilutive securities outstanding for the year ended March 31, 2010, and therefore there is
no difference between basic and diluted income attributable to Nidec Corporation per share.

20. Derivatives:

NIDEC manages the exposure of its financial assets and liabilities to interest rate and foreign exchange rate movements through the use of
derivative financial instruments which include foreign exchange forward contracts, interest rate swaps, and interest rate currency swap agreements.

The contracted amounts outstanding for foreign exchange forward contracts on March 31, 2009 and 2010 were ¥67 million and
¥123 million ($1,322 thousand), respectively.

Interest rate currency swap agreement, which mature in 2011, is designed to
reduce NIDECs exposure to losses resulting from adverse fluctuations in cash flows due to changes in interest rates and currency exchange rates on underlying debt instruments. The contracted amounts outstanding on March 31, 2009 and 2010
were ¥72 million and ¥48 million ($516 thousand), respectively.

The interest rate swap agreements, which were
designed for the same purpose as the interest rate currency swap, matured in the year ended March 31, 2009.

Nidec does not have derivatives designated as hedging
instruments under ASC 815.

21. Fair Value:

Under Statement of ASC 820, Fair Value Measurements and Disclosures (formerly SFAS No. 157, Fair Value
Measurements), fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a hierarchy for
inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that reflect the
assumptions market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect NIDECs assumptions about the factors
market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy is broken down into three levels.

Level 1 inputs are quoted prices in active markets for identical assets or liabilities.

(continued)



Level 2 inputs include quoted prices for similar assets or liabilities in active
markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs (other than quoted prices) that are observable for the asset or liability, and inputs that are derived principally from or corroborated by
observable market data by correlation or other means.

Level 3 inputs are unobservable inputs for the asset or liability.

Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value
measurement.

Assets and Liabilities that are measured at Fair Value on a Recurring Basis:

The following table provides information by level for assets and liabilities that are measured at fair value, as defined by ASC 820, on a
recurring basis.

Level 1 marketable securities are comprised primarily
of equity securities, which are valued using an unadjusted quoted market price in active markets with sufficient volume and frequency of transactions. Level 2 derivatives are valued using quotes obtained from counterparties or third parties, which
are periodically validated by pricing models using observable market inputs, such as foreign currency exchange rates and interest rates.

The following are explanatory notes relating to the financial instruments.

Cash and cash equivalents, short-term investments, short-term loans receivable and short-term borrowings: In the normal course of
business, substantially all cash and cash equivalents, time deposits short-term loans receivable and short-term borrowing are highly liquid and are carried at amounts that approximate fair value.

Long-term loan receivable: The fair value of long-term loans was estimated by discounting expected future cash flows.

Long-term debt: The fair value of long-term bank loans (including the current portion and excluding the capital lease obligation) was
estimated based on the discounted amounts of future cash flows using NIDECs current incremental borrowing rates for similar liabilities.

22. Related party transactions:

As of March 31, 2010, the Chief Executive Officer (CEO) of the Company and a business entity discussed below indirectly
owned by the CEO held 8.5% and 3.9% of the outstanding shares of the Company, respectively. There were no significant related party transactions in the fiscal year ended March 31, 2010 other than those described in Note 11.

Loan to S.N. Kohsan

In December 2008, the Company advanced a loan of ¥14,500 million to S.N. Kohsan, a company indirectly owned by the CEO. The
loan was guaranteed by the CEO and collateralized by a pledge of 4,500,000 of the CEOs shares in NIDEC. The loan had a term of 5 years and accrued interest quarterly at an annual rate of 2.4%. The loan was repaid in full on February 17,
2009 after the Company and the CEO determined that the loan was not permitted under Section 402 of the U.S. Sarbanes-Oxley Act of 2002. The loan receivable and its subsequent repayment was recorded in the balance sheet in equity and is
presented as a financing activity in the Cash Flow Statement.

S.N. Kohsan obtained the funds to repay the loan through the
sale of a total of 3,356,000 of its shares in NIDEC through the J-NET and on the Osaka Securities Exchange. Of these shares, 2,917,800 were purchased by the Company through the J-NET for a total of ¥12,867 million.

A special committee of the Companys Board of Corporate Auditors conducted an independent investigation of this matter with the
assistance of independent counsel and concluded that the failure to comply with Section 402 was inadvertent. We voluntarily brought this matter to the attention of the U.S. Securities and Exchange Commission (the SEC). The Division
of Enforcement of the SEC advised that it was conducting an informal inquiry into the issue, and we cooperated fully with the informal inquiry. We have subsequently been advised by the Staff of the Division of Enforcement that its investigation has
been concluded and that the Staff will not recommend that enforcement proceedings be commenced.

During the period the loan
was outstanding, S.N. Kohsan qualified as a variable interest entity. NIDEC was not the primary beneficiary.

24. Other commitments and contingencies, concentrations and factors that may affect future
operations:

Commitments

Commitments outstanding at March 31, 2010 for the purchase of property, plant and equipment and other assets approximated ¥2,115
million ($22,732 thousand).

Contingencies

NIDEC has guaranteed approximately ¥146 million ($1,569 thousand) of bank loans for employees in connection with their housing costs
at March 31, 2010. If an employee defaults on his/her loan payments, NIDEC would be required to perform under the guarantee. The undiscounted maximum amount of NIDECs obligation to make future payments in the event of defaults is
approximately ¥146 million ($1,569 thousand). The current carrying amount of the liabilities for NIDECs obligations under the guarantee is zero.

Concentration of risk

NIDEC is dependent on a number of large customers for a substantial portion of NIDECs net sales. Sales to NIDECs six largest
customers represented approximately 37%, 36%, and 41% of consolidated net sales for the years ended March 31, 2008, 2009, and 2010, respectively. Sales to NIDECs largest customer were approximately 11%, 10%, and 11% of consolidated net
sales for the years ended March 31, 2008, 2009, and 2010, respectively. Accounts receivable are financial instruments that expose NIDEC to a concentration of credit risk. At March 31, 2009, the six largest customers with outstanding
accounts receivable balances totaled ¥36,693 million, or 33% of the gross accounts receivable, compared to ¥61,629 million ($662,393 thousand), or 41% of the gross accounts receivable, at March 31, 2010. If any one or group of
these customers receivable balances should be deemed uncollectable, it would have a materially adverse effect on NIDECs results of operations and financial condition.

Product warranty

NIDEC guarantees the performance of products delivered and services rendered for a certain period or term. Estimates for warranty cost are
made based on historical warranty claim experience. The changes in product warranty liability for the years ended March 31, 2009 and 2010 are summarized as follows:

25. Discontinued Operations

As of December 31, 2008, NIDEC discontinued its optical pickup unit (OPU) business. The results of the OPU business were
previously recorded in the NSNK and All Others reportable segment. NIDEC discontinued the OPU business by winding down operations in an effort to concentrate management resources and focus capital and R&D expenditures on other growing
businesses. Total exit costs were ¥3,972 million (net of tax ¥2,564 million), which includes an impairment loss of ¥357 million of goodwill, loss on disposal of fixed assets and inventories, and other closing costs.

As of September 30, 2009, NIDEC discontinued the semiconductor manufacturing equipment (SME) business included within
the NTSC (Nidec Tosok Corporation) and All Others reportable segments, in order to improve profitability by prioritizing NIDECs investment of management resources to the development and production of new products in the automobile
parts and measuring equipment businesses, areas with more potential for growth than the SME business. Total exit costs were ¥1,835 million ($19,723 thousand) (net of tax ¥1,174 million ($12,618 thousand)), which includes an
impairment loss of ¥230 million ($2,472 thousand) of goodwill, loss on disposal of inventories and fixed assets, and other closing costs.

The operating results of the OPU and SME business and exit costs with related taxes were recorded as net loss on discontinued
operations in the consolidated statement of income in accordance with ASC 205-20 Presentation of Financial Statements-Discontinued Operations (formerly SFAS No.144, Accounting for the impairment or disposal of Long-Lived
Assets.). All prior period information has been reclassified to be consistent with the current period presentation.

Operating results of discontinued operations for the year ended March 31, 2008, 2009 and 2010 were as follows:

(2) Operating segment information:

The operating segments reported below are defined as components of an enterprise for which separate financial information is available and
regularly reviewed by NIDECs chief operating decision maker. NIDECs chief operating decision maker utilizes various measurements to assess segment performance and allocate resources to segments.

NIDEC changed its segment reporting in line with the changes NIDEC made in its management decision-making process from the year ended
March 31, 2010. In August 2009, NIDEC integrated the operation of Nidec Electronics GmbH into those of Nidec Motors & Actuators (Germany) GmbH within the NMA segment, and also integrated the operations in China previously included
within the NCD segment, other than the DC motors and fans operations, and the in-car motors operations previously included in the All Others segment into the NMA segment, to enhance its automobiles motors businesses. In October 2009, NIDEC
reorganized the operations of Nidec Shibaura Corporation (NSBC) and those of Nidec Power Motor Corporation into Nidec Techno Motor Holdings Corporation (NTMC) to enhance its mid-size motors businesses. As a result, NIDEC has
created the NTMC segment consisting of its operations relating to mid-size motors for home appliances and industrial use, which were previously included in the NSBC segment and the All Others segment.

The NSCJ and NNSN segments are no longer reported as reportable segments and are included in the All Other segment in the current period
due to their immateriality.

All prior period information has been reclassified in accordance with the current period
presentation.

The NCJ segment comprises Nidec Corporation in Japan, which primarily produces and sells hard disk drive
motors, DC motors, fans, and Mid-size motors.

The NET segment comprises Nidec Electronics (Thailand) Co., Ltd. and Nidec
Precision (Thailand) Co., Ltd., subsidiaries in Thailand, which primarily produce and sell hard disk drive motors.

The NCC
segment comprises Nidec (Zhejiang) Corporation, a subsidiary in China, which primarily produces and sells hard disk drive motors.

The NCD segment comprises Nidec (Dalian) Limited, a subsidiary in China excluding mid-size motors businesses, which primarily produces
and sells DC motors and fans.

The NCS segment comprises Nidec Singapore Pte. Ltd., a subsidiary in Singapore, which primarily
sells hard disk drive motors, DC motors, fans, and pivot assemblies.

The NCH segment comprises Nidec (H.K.) Co., Ltd., a
subsidiary in Hong Kong, which primarily sells hard disk drive motors, DC motors and fans.

The NCPL segment comprises Nidec Copal Corporation, a subsidiary in Japan, which primarily produces and sells optical and electronic
parts and machinery.

The NTSC segment comprises Nidec Tosok Corporation, a subsidiary in Japan, which primarily produces and
sells automobile parts and machinery.

The NCEL segment comprises Nidec Copal Electronics Corporation, a subsidiary in Japan,
which primarily produces and sells electronic parts.

The NSRV segment comprises Nidec Servo Corporation in Japan, which
primarily produces and sells DC motors, fans and other small precision motors.

The NTMC segment comprises Nidec Techno Motor
Holdings Corporation, a subsidiary in Japan, and its subsidiaries in Japan, China and Thailand, which primarily produce and sell mid-size motors.

The NMA segment comprises Nidec Motors & Actuators (Germany) GmbH, other subsidiaries in Europe and North America, and other
manufacturing subsidiaries in China, which primarily produce and sell in-car motors.

The All Others segment comprises
subsidiaries that are operating segments but not designated as reportable segments due to materiality.

NIDEC has 14
reportable segments, NCJ, NET, NCC, NCD, NCS, NCH, NCF, NSNK, NCPL, NTSC, NCEL, NSRV, NTMC and NMA which have been identified in accordance with ASC 280, Segment Reporting (formerly SFAS No. 131, Disclosures about Segments of
an Enterprise and Related Information).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NIDEC evaluates performance based on segmental profit and loss, which consists of sales
and operating revenues less operating expenses. Segmental income or loss is determined using the accounting principles in the segments country of domicile. NCJ, NSNK, NCPL, NTSC, NCEL, NSRVs operating income or loss is determined using
Japanese GAAP, NET applies Thai accounting principles, NCC and NCD apply Chinese accounting principles, NCS applies Singaporean accounting principles, NCH applies Hong Kong accounting principles, NCF applies Philippine accounting principles, NTMC
mainly applies Japanese GAAP, and NMA applies mainly International Financial Reporting Standards (IFRS). Therefore NIDECs segmental data has not been prepared under U.S. GAAP on a basis that is consistent with the consolidated financial
statements or on any other single basis that is consistent between segments. While there are several differences between U.S. GAAP and the underlying accounting bases used by management, the principal differences that affect segmental operating
income or loss are accounting for pension and severance costs, and leases. Management believes that the monthly segmental information is available on a timely basis and that it is sufficiently accurate at the segment income or loss level for
managements purposes.

|4) Number of shares of the Company allocated in the share exchange |  | Nidec expects to allocate 731,673 shares of its common stock in the Share Exchange. Nidec intends to use shares of its common stock held in treasury, and
does not intend to issue any new shares, for the Share Exchange.
