Message from Top Management

Proudly Committed to Our Core Business
The Very Essence of Komatsu’s CSR
CSR Activities in Response to the
Earthquake and Tsunami Disaster
Looking back at FY 2011, this was a year to focus on recovery
after the unprecedented earthquake and tsunami disaster in the
Tohoku area - a disaster that helped us discover what it is that
corporations can do for society.
Komatsu regards its Corporate Social Responsibility (CSR)
activities as an essential part of its core business. In our efforts todeal with this disaster, we have provided assistance by seeking tounderstand how we can fill the needs of the affected areas within
the framework of our business, keeping in mind that people often
need goods more than money.
The Komatsu Group has more than 670 employees in the threedisaster stricken prefectures of Iwate, Miyagi and Fukushima, andtheir work has always been closely linked to these local communities. I have personally visited these areas seven times to provide
encouragement, and through these visits I have learned that every
employee is listening to the stories of individual disaster victims
and trying his/her utmost to offer support.
In addition to direct business-related activities, such as sales,
rental, and service of construction machinery required for recovery
and reconstruction, Komatsu has set up a dedicated department
in Sendai City responsible for overseeing disaster recovery
measures. Establishing this department has enabled us torespond promptly to the various needs of the region. By hearing
the voices of the people of the community, we consider how best
we can meet our corporate social responsibility by drawing on
our management resources, and have executed various disasterrecovery measures.
I hope that various companies will continue to support andcollaborate through utilizing core businesses in order to help therecovery and reconstruction of the disaster area. (Komatsu s
initiatives in the disaster area are described in more detail in ourSpecial Story on page 39.)

Environmental Activities
Komatsu views its environmental activities as one of its toppriority management tasks and drives campaigns to reduce
environmental impact in all phases of its business operations inorder to meet the Mid-Range Management targets set two yearsago.
To address climate change related concerns, Komatsu is
working to reduce environmental impact throughout the productlifecycle, focusing on reducing CO2 emissions from the use of
products, such as hybrid hydraulic excavators and AutomatedMachine Control/Guidance System by utilizing ICT (Information
and Communication Technology). Komatsu is also promoting its
biodiesel fuel program, which is hailed as carbon-neutral, forlocal production and consumption.
In its domestic production activities, when Komatsu was
requested by the government to trim its peak power 15% amid
concerns in the summer of 2011 over power shortages triggeredby the nuclear power plant accident during the Tohoku earthquake, we realized a reduction of 30% or more. This summer,
Komatsu has channeled its capital investment into private power01

CSR & Environmental Report 2012

generators and other facilities in a bid to cut the peak power by
25% from the summer of 2010. It also aims to drive the CutPower Consumption by Half campaign in a three-year programto achieve both increases in domestic production and a reductionof CO2 emissions.
Additionally, Komatsu continues its efforts to promote recyclingof certain components, such as engines, and to reach zero
emissions, which Komatsu defines as a recycling rate as
99.5% or higher. We strive to drive reductions in the usage ofenvironmental load substances, such as lead and mercury, andphase in the marketing of construction machinery compliant with
the Japanese, U.S. and European emission regulations.
Further, Komatsu established the Declaration of Biodiversity
two years ago to explore relationships between its operations andbiodiversity and also a one-site, one-theme activities campaign.
To bolster sustainable growth, Komatsu is working to enhancethe effectiveness of its environmental activities by partnering withoverseas affiliates, rental dealers, suppliers, and distributors.

Shouldering Our Corporate
Responsibility
Construction equipment for building towns and roads, mining
equipment for extracting resources, and forestry machinery for
production of timber and pulp - Komatsu products and services
help build countries and create better living conditions worldwide.
In the process of developing Komatsu s business, people inmany parts of the world receive training in service technology,
accelerating the development of local human resources. Furthering business activities in this manner is directly linked to our CSR
activities, and I always tell our people that I want them to do theirwork responsibly and with pride.
But there are, of course, rules that must be followed andresponsibilities that must be met in this process.
Komatsu s Worldwide Code of Business Conduct lays down
the rules to be observed by people around the world who workfor Komatsu or are related to Komatsu s business. The CodeContents
Message from Top Management …………… 01
OUR APPROACH TO CSR …………………… 03
has been revised repeatedly and has recently been translated
into local languages. The eighth edition of the code publishedin FY 2011, was issued not only in Japanese and English, but
in fourteen other languages, so that employees worldwide will
be able to understand it and conduct themselves accordingly.
Through sharing these basic rules on a global scale, we strive tomeet our social responsibility to observe the laws and regulationsof each country or region and act in accordance with its culture
and customs.
Recognizing our responsibility as a company with businessevolving around the world, Komatsu is also a signatory to the
UN Global Compact. We and our business partners will act
through our supply chain in consideration of this voluntary code of
conduct.
Komatsu s global network shares the basic management
stance that our corporate value is the total sum of trust given to
us by society and all stakeholders, as we fulfill our responsibility
to society through promoting CSR activities and pursuing sustainable growth.

Dialogue with Our Stakeholders
Komatsu has always placed great value in the Company s
process for interacting and maintaining a dialogue with allof its stakeholders, including employees, business partners,
investors, shareholders, and local communities. We also
invite stakeholders from outside the company to voice theiropinions on the Company s management and business.
In November 2011, Komatsu representatives invited theprofessors of four Japanese universities (Yokohama National
University, Osaka University, Kanazawa University, and The
University of Tokyo), with which Komatsu has concluded
industry-academia collaboration agreements, to hold thefirst meeting of the Komatsu Industry-Academia Scienceand Technology Collaboration Council. Komatsu asked
the academics to submit proposals from the perspective
they gained through joint research with Komatsu, based on
current social trends and Komatsu s technical domain.
Komatsu also held meetings on industry-academia

collaboration in China, with Shandong University and Tongji
University, resulting in announcements and deliberations on
internships, joint research, and other topics. The proposals
and opinions solicited through this dialogue were both
helpful and unique, and we will make efforts to see themreflected in our business and management methods.

Komatsu uses the broad expression enhancing
quality of life to describe the key theme behind its
CSR activities. How do you interpret these words?

shipped from these locations are designed to reduce theirenvironmental impact.

Takahashi: There are many types of business. Komatsu sbusinesses is built on products that improve the social infrastructure, and also products used in fields such as naturalresource mining and the forestry industry. So these words
refer in a literal sense to enhancing the lives of people. Eachof these key activities reflects Komatsu s core business,
and I feel that this is consistent with our basic stance ofconducting our CSR activities through our core business.
But, I think there may be some people who worry about
the environment being harmed by our activities, or about
the environmental impact of our production activities andproducts.
First of all, to reassure people in the local communities
where we operate, we must strive to take thoroughmeasures to ensure safety and protection of the environment, and explain these measures to the public. We should
also make the greatest efforts to ensure that productsTrends at international conferences dealing with theglobal environment show many scenarios for what
each party should be doing. Komatsu, too, is taking
a variety of initiatives. Can you please describe
Komatsu s principal policy and strategic direction inthis regard?

CSR & Environmental Report 2012

Takahashi: We have been keeping a close eye on global
trends, based on the handling of the Kyoto Protocol and thedeliberations at the United Nations Framework Convention
on Climate Change (UNFCCC/COP). Komatsu will pursue
its current policies and strive to bring them into line with theneeds of society. At the top of the list is our basic, unchanging policy of contributing to sustainable development.
In addition to reducing the environmental impact of our
production activities, Komatsu is actively working towards
sustainable development through recycling programsFaced with power shortages following the nuclear
power plant accident in March 2011, the reductionof power consumption has become a pressing issue
in Japan. In addition, it is being viewed as a means
to reduce emissions in the interest of environmental
protection.

What are you doing to improve safety?

Growing with Society
Data

Takahashi: Komatsu is a company that prides itself on
putting safety first. Fuel economy and environmental
performance are often the most appealing aspects of the
products we supply to our customers, but we are always
pursuing Dantotsu (unique and unrivalled) features insafety. Adopting ICT is an important factor in distinguishing
the safety performance of our products from those of othermanufacturers, and that is why we have made it one of thepillars of our basic R&D policy.
As our business evolves around the globe, we are specifically addressing the advancement of our worldwide safety
activities to the level where they are Dantotsu, while also
targeting safety in production and at the work site.
Some Komatsu plants around the world do not havea very long history, but it is nevertheless important thatour plants make safety a priority. Hence Komatsu has set
up a system under which so-called mother plants with
R&D capability provide guidance to child plants in otherparts of the world that manufacture the same products.
For example, the Osaka plant where I worked until Marchhosts approximately forty manufacturing engineers and site
supervisors each year from child plants in China, India andother countries. The purpose is not only to pass on production skills, but also to provide thorough training in safety
standards and initiatives.
Through global teamwork in our activities around theworld, we would like Komatsu to be recognized as acompany that maintains a high level of safety, while bringing
peace-of-mind to local residents.

Developing People

Takahashi: Komatsu is currently implementing measureswith the goal of halving our peak power usage (themaximum power consumption within a specific period;
usually expressed as a one-hour average) until FY2014.
At the same time, a number of our plants are also working
to reduce their overall power consumption by one-half.
While maintaining production capacity is a necessity, we
are making efforts to close less energy-efficient buildings
or integrate them with other facilities, and reduce grossfloor area. In addition to using in-house power generators,
we plan to reduce power consumption through a variety ofmeasures, such as the replacement of production equipment with more energy-efficient models, and the use ofgroundwater for office air-conditioning systems.
Additionally, we are preparing for protracted energy-supply
instability by establishing a sustainable production systemthat will be better able to operate under such conditions.

Enhancing Quality of Lifefor components such as engines, and our biodiesel fuelproject, among others.
One of the trends we have focused on in recent years
relates to measures for mitigating climate change. Oneof the key areas in which Komatsu has been active not
only concentrates on production, as in the past, but also
focuses on research and development (R&D) to develop
products with lower greenhouse gas emissions, such as
CO2, over the product s entire lifecycle. According to our
calculations, when a product such as a hydraulic excavator
is manufactured and utilized at a job site, 90% of the CO2
emissions over the course of its lifecycle will be generated
while it is in operation at the worksite. This shows us thatviewing these matters by only examining the activities weare directly involved in, such as production, may not be
the most effective initiative to reduce CO2 emissions. Whatis important is to think about what additional measures
we can take to reduce the environmental footprint of our
products. Take, for example, the hybrid hydraulic excavator
introduced to the market in 2008. By the end of March
2012, approximately 1,500 units were in use worldwide.
Considering that their CO2 emissions during operation canbe reduced by 25%, this can have a very significant impact.
The second new perspective is dealing with biodiversity.
At the 10th meeting of the Conference of the Parties to theConvention on Biological Diversity (COP 10) held in Nagoya
in 2010, an alarm was sounded regarding the continuingpace of species extinction, with no letup in sight. Komatsu,
rather than responding through our supply of products andservices, sees this as a problem to be addressed throughthe corporate social responsibility policies of our businesses
in each locality. Our ongoing measures to bring production
activities into line with environmental conservation naturally
contribute to maintaining biodiversity. Additionally, we
have also embarked on our own one-site, one-theme
activities . For example, the testing site in Usuki City, Oita
Prefecture, is located on a vast site surrounded by richforest. Since 2010, it has been the site of a pilot project that
has improved the environment by successfully securing a
habitat for rare animals through the creation of a satoyama(nature area) rural landscape and a biotope that combineswaterfront and forest. Similar initiatives are in progress atbusiness units within Japan and abroad.
Through these various initiatives, Komatsu aims to fulfill its
corporate social responsibility and, at the same time, strive
to become a company trusted by all Komatsu stakeholders.

Become Invaluable to Our Customers,
who Both Create and Assess Our
Corporate Value

Realizing Our Customers Vision
and Mission, from the Customer s
Perspective

Komatsu embodies this concept in our statement that
our corporate value is the total sum of trust given to us
by society and all stake holders. We have made raising theCompany s corporate value the basic stance of management.
If we group our various stakeholders into those who
create corporate value and those who evaluate corporate
value, the former role would fall to employees, business
partners, and sales and after-sales service agents, andthe latter would include society, shareholders, investors,
and the media. As we see it, only our customers take on
both of these roles. Customers both create and assess our
corporate value, and feed the result back to us in return.
Heightening the trust placed in us from our customers
was then defined as increasing the degree to which ourcompany is indispensable to our customers and as a resultcontinues to be selected as the partner of choice. Initiatives
in this regard for brand management activities have been
under way since 2007.

Komatsu s basic policy regarding Brand Management
activities is from the customer s perspective. People often
think that marketing activities are about ways to differentiate
one s products from those of competitors, and about
positioning oneself in the market. But this is not the case.
Acting from the customer s perspective refers to the ideal,
and the mission, of discovering what customers want andof responding to these needs.
To realize this, we are engaged in activities designed todevelop and improve our own management resources andcapabilities on an ongoing basis. In the past, these initiatives tended to rely on experience and intuition, but in thecontext of Komatsu s Brand Management activities, we are
now using a variety of tools and methods to develop casestudies and accumulate know-how to be passed on to thenext generation.
In other words, Komatsu s Brand Management activities
refer to The KOMATSU Way applied to marketing andcustomer relationships. The idea is not to simply raise sales
and profits and increase market share in the short term,
but to use these activities to interact with customers andheighten customer trust by visiting their workplace, while atthe same time improving the level of our employees and thestrength of our organization.

Currently, we are developing Brand Management activities targeting
90 client companies in 18 countries. Case studies are shared among
Group companies worldwide and regular meetings are held to provide
opportunities to learn from each other. This photo shows a meeting held
in November 2011, which was attended by 48 representatives from 16
countries, with 39 representatives from Japan.

Rio Tinto s Mine of the Future™

Voice

Mr. Noboru Yamaji
President, Rio Tinto Japan

Our mottos at Rio Tinto are becoming a leader in themining industry and becoming the best company , but thisdoes not mean the desire to simply achieve top sales andmarket share. With best we mean that first of all, our operations should be safe. We are also focused on the well-beingof our employees and their families, building trust, providing

stable quality, and ensuring stable supply.
As t he w or l d s p op ul at i on p as s es se v en b i l l i o n , th eworldwide demand for resources will inevitably increase. This
demand is moving the worksites of the extraction industry, of
which we are part, ever farther away from ports and deeper
into the earth. A common problem at these kinds of worksitesthat inevitably arises for companies in all regions is securing acapable workforce. I think the only way to solve this problem
is through automation and remote control technology.
Komatsu has been our partner for 40 years. Even though
our positions differ, we share the same values, solve issues
that need improvement through discussion, and build a
relationship of mutual trust. We would like to continue tomove forward together with Komatsu, with whom we share
a common destiny, to transform our mottos and dreams into
reality.

Rio Tinto s Mine of the Future™
For future access to resources, we are looking
beyond our current licence to operate and thinking
about better ways of mining.
With our Mine of the Future™ programme we aredemonstrating improvements to mining processes
that include unprecedented levels in automation, andremote operations that will revolutionise the way mining
has been conducted for more than 100 years.
Mine of the Future™ will help us improve oursustainable development performance in several areas.
The programme is designed to create next generation
technologies for mining operations that result in greater
efficiency, lower production costs, improved health,safety and environmental performance, and more
attractive working conditions.

As one means of realizing this objective, Komatsu has
developed and introduced its Autonomous Haulage System(AHS), an unmanned dump truck operation system.
AHS consists of unmanned dump trucks, manned nontruck vehicles, and an operation management system thatmanages the entire mining operation. With this system, customers can manage their fleets with fewer drivers, thereby
protecting employees from difficult working conditions and,at the same time, reducing operating costs. This also helps
improve safety by significantly reducing accidents causedby driver error. AHS also optimizes driving performance,
which improves productivity and reduces fuel and tire costs.
Komatsu realized this system by matching its in-housemanagement resources, in the form of its extensive experience in unmanned haulage technology, with the working
processes in the customer s mines. We continue to make
improvements based on actual on-site work experience.

Enhancing Quality of Life

Rio Tinto is a leading international resource developer andmining group and one of Komatsu s most valued customers; Komatsu supplies dump trucks and other mining
machinery to the group.
To ensure the stable extraction and supply of limited
resources, mining sites are moving farther away frominhabited areas and extracting materials at deeper levels,
resulting in an ever more challenging working environment.
That is where Rio Tinto arrived at the concept of Mine of
the Future™ , an idealized model that harnesses stateof-the-art technology to enable employees thousands ofkilometers away to run mining operations by remote control.

We, at the Komatsu Group, work for sustainable society and earth environment through our global business operations by addressing thefollowing four environmental problems with the stances discussed below
1) Climate Change
We will reduce the use of energy and emissions of greenhouse gas in all phases of our business activities ranging from research anddevelopment, procurement, production and logistics to sales and service as well as in the total life cycle of our products and services.
2) Establishment of a Sound Material-Cycle Society
Through our business processes, we work to minimize the use of natural resources, such as materials and water, promote their re-use
or recycle them as much as possible, and expand Zero Emissions from our manufacturing activities around the world. At the same time
we ensure the thorough management of waste materials in all our business domains, including our suppliers and distributors. We also
continuously work to increase the recyclability rate of products at the time of disposal.
3) Conservation of Air, Water and Other Nature Resource as well as Management of Chemical Substances
We comply with not only local laws and regulations but also with our established standards concerning the conservation of water quality,
prevention of air pollution, noise and vibrations.
As much as possible, we also ensure the thorough management of chemical substances for use in our business activities, while continuously reducing the use of potentially harmful chemical substances or replacing them with alternative substances for discontinuation of
their use.
4) Biodiversity
We recognize biodiversity as one of the important issues concerning the earth environment, evaluate, understand and analyze impact on
it in all our business domains, and work on our tasks according to the criteria of the highest impact and/or the most effective actions.

2. Framework of Global, Group-wide Environmental Management System
The Komatsu Head Office, as well as the manufacturing facilities and main companies of the Komatsu Group, already with ISO certifications,will work to maintain and improve their environmental management system, while other manufacturing facilities and suppliers will also workto establish their environmental management systems and reduce their environmental impact.
The Komatsu Environmental Committee develops environmental action plans and common guidelines for the Komatsu Group. Basedon these Group-wide plans and guidelines, each division or company sets up its own mid- to long-term targets, develops and implements
specific action plans, reviews them regularly and works to continuously improve them.

Recycling amountCO2 emissions : Calculated by multiplying the electric power, heavy oil, etc. consumed (see Energy section of Input column) by the CO2 emission coefficient (according to the Greenhouse Gas Emissions Calculation - Reporting Manual of the Ministry of the Environment based on the Act on Promotion of Global
Warming Countermeasures)
SOx emissions : Calculated by multiplying the “S content by percentage” (based on element tables of suppliers) by the amounts of heavy oil, kerosene, light oil, andcoke used.
NOx emissions : Calculated by multiplying the “nitrogen oxide emissions units” (obtained at each Komatsu facility) by the amounts of heavy oil, kerosene, light oil,natural gas, and LPG used.
Emissions and transfer of substances covered by the PRTR Law: Calculated by the “content ratio of specific chemical substances” contained in indirect materials
multiplied by the “discharge or transfer rate.” This calculation is based on the PRTR Law, which was designed to mandate the disclosure of the amount of specificchemical substances released into the environment to promote the management of such substances.

2007, Thailand and Indonesia in 2009, and India in 2010,
Komatsu representatives visited our subsidiary in Brazil(KDB, Komatsu do Brasil Ltda.) in FY2011 to inspect thefacilities and exchange views on environmental matters.
Komatsu also inspected the premises of the local wastedisposal companies that the subsidiaries use. At KDB,
activities such as saving energy, evaluating air and water
quality, and separating waste materials were being diligently
pursued. Moreover, KDB has implemented measures tolower environmental risks by, for example, voluntarily replacing roof slates containing asbestos. We found no criticalenvironmental risks at KDB.
Komatsu plans to continue
environmental inspections
in overseas subsidiaries in
the future, to promote soundenvironmental practices for the
Komatsu Group as a whole.

Promoting Environmental Activities at Group Sales Agencies
Komatsu s support for environmental activities extends
to forklift sales agencies, as well as construction machineryand rental companies, through education and guidance on
ways to enhance environmental management.
The Environmental Guidelines for Sales Agencies comprise guidelines and standards pertaining to environmental
issues that are of direct relevance to operations at sales
agencies and rental companies. These include waste treatment, waste-oil treatment, oil-and-grease management,
and treatment of wastewater from vehicle washing.
Komatsu assists sales agencies and rental companies inmeeting the provisions of the Environmental Guidelines. The
company also assists in reviewing the environmental aspects ofoperations, conditions, and equipment at the relevant businesssites of the agencies and companies, gives on-site guidance,and proposes remedial actions that are tailored to each site.
This is done through joint visits to each of the sites by persons
in charge of environmental management at Komatsu and at
the sales agencies and rental companies. (In FY2011, 156
sites received this assistance.) As a result, awareness of theenvironment has risen at agencies and companies, and various
improvements are underway.

Komatsu has implemented a Group-wide initiative toacquire ISO14001 certification, an international standard
for environmental management systems. The objective is toenhance management quality by strengthening systematic
steps towards environmental conservation.
Since 1997, several manufacturing facilities both inside
Japan and abroad received certification. In FY2005, the four
plants belonging to Komatsu Ltd. (theparent company), the Awazu, Osaka,
Mooka, and Oyama Plants, acquired
integrated certification. As the second
step, in FY2007 Komatsu added its
major affiliates in Japan and yet-to-becertified non-manufacturing facilities
̶ notably the Head Office ̶ to theabove four plants, with integrated
certification attained by the Group in
Japan in May 2008.

Certification
Upon completing the March 2012

reassessment audit, the KOMATSU Way Comprehensive
Learning Center and Komatsu NTC Ltd. were included in
the integrated certification. The Group seeks to raise thelevel of management in Japan.
Additionally, an overseas affiliate, KUCC (Komatsu Undercarriage China Corp.), attained certification in December
2011 and STAVMEK (Stavmek s.r.o.: Czech Republic),
attained certification in April, 2012. We will further promote
the certification of overseas manufacturing facilities into the
future.

In Komatsu Group s basic education system, the parent
company and individual divisions share the responsibility
for education. The parent company develops educational
materials and provides educational services on relevant
academic issues for use by Komatsu Group companies. Individual divisions, on the other hand, provide instruction on
more hands-on matters, including unique features particular
to the individual divisions. Education and training is tailoredto different occupational content, and includes lectures on
the environment.
In FY2011, environmental education was administered on
the basis of essentially the same curriculum as in the preceding year. Education in the environmental code launchedsince 2010 was contined into FY2011. Activities designed
to enhance awareness of the importance of biodiversity
protection among employees were also implemented
proactively.
Komatsu encourages employees to obtain an appropriate

Activities to Cut CO2 Emissions at Suppliers

To help reduce the CO2 emissions produced by our suppliers,
we singled out from our key suppliers three of 41 designated suppliers that have an energy consumption of 1,500 kℓ/year or more(crude-oil equivalent), and supervised and supported these modelcompanies in their efforts to reduce CO2 emissions. In FY2012,
Komatsu expects to reinforce these efforts, expanding upon the
success of the campaign to reduce CO 2 emissions to involveother companies, and strengthen the deployment of Komatsu senergy-saving campaigns among our suppliers.

Activities to Cut CO2 Emissions from
Construction Equipment in Operation(Energy Saving Operation Training Session)

As for Komatsu s 20 ton class hydraulic excavators, 30% of
the engine operating time is spent idling. During the 70% of
operating time during which the excavator is in active operation,
the excavator consumes 20% more fuelthan what Komatsu considers efficient.
At an energy saving operation training
session in Techno Center, Komatsu
introduces the following driving method:(1) Use the equipment in an intelligent
Training Session formanner, (2) Simplify the workflow of Energy-Efficient Operation(Izu Techno Center)
construction work, and (3) Eliminate
factors leading to inconsistency and waste. We have attained
more than 35% increase in fuel efficiency through more efficient
use and driving methods.

Reducing CO2 Emissions in Non-manufacturing Divisions

value with respect to the amount of electricity, fuel gas, fuel oil,and other types of energy used in manufacturing operations. The
Company has set a target of 20% reduction in CO2 emissions by
the average in FY2008 to FY2012, compared to the FY2000 level.
In 2011, medium-term goals had been attained ahead ofschedule for the sixth consecutive year. The primary impetus
came from enhanced production efficiency, which resulted fromthe inauguration of a new high-efficiency line and the removalof an obsolete line, from the horizontal deployment of various
improvements from the Company-Wide Energy Saving Working

Thermoelectric Modules

Thermoelectric modules are an industrial implementation of
the Seebeck effect, in which a temperature difference is applied
to two dissimilar metals that are joined together, to produce acurrent flow between the metals. These modules are available
from KELK Ltd. Thermoelectric modules are now used for factory
illumination at the Awazu Plant after 13,000 hours of verification
testing at its heat-treating furnace. Komatsu is taking part in theimplementation of the NEDO project R&D project for thermoelectric generation by using waste heat in the steelmaking process torealize practical technologies. If waste-heat recovery is adopted in
50% of the plants in Japan, it is estimated to reduce 1 million tonsof CO2 in annual emissions (electrical conversion: 2.9 x 109 kWh).

Activities to Cut CO2 Emissions at Suppliers

To help reduce the CO2 emissions produced by our suppliers,
we singled out from our key suppliers three of 41 designated suppliers that have an energy consumption of 1,500 kℓ/year or more(crude-oil equivalent), and supervised and supported these modelcompanies in their efforts to reduce CO2 emissions. In FY2012,
Komatsu expects to reinforce these efforts, expanding upon the
success of the campaign to reduce CO 2 emissions to involveother companies, and strengthen the deployment of Komatsu senergy-saving campaigns among our suppliers.

Activities to Cut CO2 Emissions from
Construction Equipment in Operation(Energy Saving Operation Training Session)

As for Komatsu s 20 ton class hydraulic excavators, 30% of
the engine operating time is spent idling. During the 70% of
operating time during which the excavator is in active operation,
the excavator consumes 20% more fuelthan what Komatsu considers efficient.
At an energy saving operation training
session in Techno Center, Komatsu
introduces the following driving method:(1) Use the equipment in an intelligent
Training Session formanner, (2) Simplify the workflow of Energy-Efficient Operation(Izu Techno Center)

In FY2011 Komatsu set a new medium-term target of achieving
a 25% or greater reduction in the amount of water used per unitof manufacturing value by FY2015, compared to the FY2005
level. The water-conservation campaign concentrated on manufacturing facilities with extensive groundwater usage located in the
Hokuriku District. The company has achieved reductions in theamount of water used per unit of manufacturing value by 39.1%
compared to the FY2005 level, through the reuse of water during
processing and the elimination of wasteful day-to-day practices.
In particular, the Awazu Plant greatly cut back on its groundwater consumption through measures such as assessment of
the wells from which groundwater is taken and installation ofwater-circulation equipment to heat-treating equipment. As aconsequence, the Awazu Plant was able to trim water usage by
40% per unit of manufacturing value.
Komatsu will continue efforts to save water resources to achieve

Responding to the increase in environmental awareness aroundthe world, Komatsu has been making efforts from an early stage
to reduce the use of asbestos, lead, and other substances ofenvironmental concern. In FY1999, Komatsu stipulated its own
list of banned substances and substances approved for use only
in limited circumstances (see table below), using as its base thechemical substances banned under Japan s Law Concerning
the Examination and Regulation of Manufacture of Chemical
Substances Control, as well as other regulations in individual
countries. At the same time, Komatsu began comprehensive
control of substances of environmental concern. Recently, incompliance with REACH*1, Komatsu is revising our designationof substances approved for limited use, to to be reduced andbanned. Through the cooperation of suppliers, the Company

has initiated a system to strengthen control of substances ofenvironmental concern in products. This system has been
deployed in Japan and Europe, and is also being implemented inother overseas subsidiaries.
By using this system, we identify SVHC (substances of very
high concern) in vehicles not only for shipment to and currently
in production in EU, but also identification of SVHC in newly
developed vehicles. Furthermore, we also regularly check for new
SVHCs that are continuously added to the list.
There are currently 73 (SVHC) registered, however more areadded on a bi-yearly basis. Komatsu has devised a workflow
to control these substances, and we are currently reviewing its
implementation.

*The share from the former Kawagoe Plant is included in the Head office total.

Construction of Komatsu Cabtec s powder coating line wascompleted in 2007. The line uses two coating robots to coat parts
such as cabs, doors, and air-conditioner external air covers in thesealed coating chamber. The line s design embodies the following
environmental improvements.
1）No volatile organic compound (VOC) emissions
2) Better coating ratio (95% as compared to 40% for solvent
coating, resulting in less coating material being used
3) Use of low temperature-curing coatings for lower drying
temperatures, thus saving energy (175 ℃ compared with ageneral drying atmospheric temperature of 200 ℃ )4）Better appearance due to powdering, and fully automatedoperation realized through visual monitoring of the operating
status.

*: Bio-remediation is purification process of hazardous materials through utilizing microorganisms and returning the soil to a non-hazardous state.
*Surveys revealed no contamination for the Koriyama Plant, Research Division in Hiratsuka,

Komatsu has established guidelines for testing soil andgroundwater at our Japan facilities, and we perform investigations
according to applicable laws and regulations at business units thatare to be sold, closed, or demolished. If contamination is found,
the Company takes appropriate measures under the supervisionof local authorities. We are performing voluntary investigations atcurrently operating business units to check for contamination fromvolatile organic compounds (VOC) from cleaning solvents that wereused in cleaning and other applications in the past. Komatsu has
been surveying soil and groundwater for VOC contamination atGroup business units in Japan since 2005. Business units wherecontamination was detected have implemented countermeasures.
The Company chose methods to clean up the sites as quickly as
possible. Work at the Oyama Plant was completed in FY2009. In
FY2011, change in land character notifications were filed at the
Oyama and Koriyama Plants, in accordance with the provision of
Article 4, Amended Soil Contamination Countermeasures Act, but
no survey order was issued from the administrative authorities because there was no concern over possible contamination. We willcontinue land-purification work and monitor the situation to ensurethat groundwater that does not meet environmental standards iscontained on the premises.

Environmental Risk Management
Reducing the amount of PRTR-related substances and VOC released

Komatsu is committed to thoroughly implementing measures that mitigate and prevent pollution, in strict compliance with the legal
requirements of national and local authorities, to minimize the environmental risks that accompany manufacturing activities.

Most of released PRTR-related substances and VOC are
VOC used in paint. In FY2011, the amount of such substances
released increased as production increased. Komatsu is making
efforts to reduce the amount by (1) shifting to high solid paint and(2) improvement in paint application rate.
※	P RTR: Law designed to mandate the disclosure of the amount of specific chemical
substances released into the environment to promote the management of such substances(The notification system based on the PRTR Law)

▶ Names of Class I Designated Chemical Substances and the Amounts Released andKomatsu Group companies are responsible for periodicallyreporting and archiving environmental measurement results, inaccordance with applicable laws and regulations of national andlocal authorities. In FY2011, the Komatsu Group had no environmental infraction and no major accidents where the environment
was polluted in Japan.

such as cabs, doors, and air-conditioner external air covers in thesealed coating chamber. The line s design embodies the following
environmental improvements.
1）No volatile organic compound (VOC) emissions
2) Better coating ratio (95% as compared to 40% for solvent
coating, resulting in less coating material being used
3) Use of low temperature-curing coatings for lower drying
temperatures, thus saving energy (175 ℃ compared with ageneral drying atmospheric temperature of 200 ℃ )4）Better appearance due to powdering, and fully automatedoperation realized through visual monitoring of the operating

Komatsu has established guidelines for testing soil andgroundwater at our Japan facilities, and we perform investigations
according to applicable laws and regulations at business units thatare to be sold, closed, or demolished. If contamination is found,
the Company takes appropriate measures under the supervisionof local authorities. We are performing voluntary investigations atcurrently operating business units to check for contamination fromvolatile organic compounds (VOC) from cleaning solvents that wereused in cleaning and other applications in the past. Komatsu has
been surveying soil and groundwater for VOC contamination atGroup business units in Japan since 2005. Business units wherecontamination was detected have implemented countermeasures.
The Company chose methods to clean up the sites as quickly as
possible. Work at the Oyama Plant was completed in FY2009. In
FY2011, change in land character notifications were filed at the
Oyama and Koriyama Plants, in accordance with the provision of
Article 4, Amended Soil Contamination Countermeasures Act, but
no survey order was issued from the administrative authorities because there was no concern over possible contamination. We willcontinue land-purification work and monitor the situation to ensurethat groundwater that does not meet environmental standards iscontained on the premises.

The Biodiesel Fuel (BDF) Project was launched in2009 to produce biodiesel fuels (BDF) from jatropha andother plants at the Adaro Mine in Indonesia to fuel Komatsu dump trucks. In 2010, Komatsu built a pilot plantfor BDF production, along with a laboratory to ensure
the quality of the BDF in production. Since 2011, testinghas been carried out on Komatsu BDF-fueled dump
trucks at the Adaro Mine, to aid in our manufacturing

Komatsu has continuously pursued both productivity improvements andenergy-saving activities.
After experiencing power shortages in the service areas of Tokyo ElectricPower Co., Inc. and Tohoku Electric Power Co., Inc. during the summer of 2011,
it is anticipated that power shortages will occur during the summer of 2012,
and will include the service area of Kansai Electric Power Co., Inc., as well. In
response to this, Komatsu will be implementing large-scale reductions in power
consumption. Our goal is to cut summertime peak power needs by 25% in 2012and by 50% in 2014, compared to consumption levels in 2010. We also plan tolimit consumption to reduce the environmental impact from CO2 emissions.
The fundamental methods for power reduction that we will use are:❶ Electricty utilization control to eliminate waste by realizing lower energy
requirements❷ Utilizing alternative energy sources❸ Revamping production
Specific measures for achieving these goals are summarized below. By adapting these ideas, we plan to establish new plants that require only half the energy
our current facilities use to operate.

Masanao Mori
Executive Officer, GM, Human ResourcesSupervising Education and Safety & Health Care,
Komatsu Ltd.

The theme of respect for employees and theirfundamental human rights emerged when Komatsu
was deciding on CSR priorities. Could you explain
the corporate stance towards this theme?
Mori: Every one of our employees is a valuabe asset to ourcompany.
Upholding their fundamental human rights, and respecting
their personality and individuality, is our basic personnel
policy around the globe.
So what specific measures do we take? People often
talk about improving labor conditions and the working
environment, but I believe the most important thing is communication with employees.
As outlined in The KOMATSU Way, the Company endeavors to provide an environment where top management
can communicate with employees individually, to explain
the company s point of view and to listen to opinions
and questions from employees. Examples of this include
employee meetings held with the President after the releaseof our half-term performance records, onsite meetings at

between the Company and labor unions and employee
representatives.
By building a trusting relationship between the company
and its employees through honest discussion and debate,
the company develops further and the lives of our employees are enriched. To create win-win situations such asthese, I believe that daily communication and the sharing of
information are vital.
Do you have measures regarding human rights andemployment from a global perspective?
Mori: What is essential when reviewing personnel policies
from a global perspective is to recognize and understandhow personnel systems differ depending on the region
and how they reflect each region s historical and cultural
background. It is therefore necessary to consider regional
conditions and deploy systems and policies suitable to that

Mori: For the last few years the consolidated number ofKomatsu employees has increased rapidly, in pace withour corporate expansion, rising about one and a half
fold compared to ten years earlier. Especially in strategic
markets such as those in emerging nations and resourcerich nations, the rapidly increasing number of employees
working in production and as dealer servicepersons has
resulted in a proportionate increase in numbers of newer
employees.
In Japan at Komatsu alone, 40% of our employees havebeen working at the Company for less than five years.

Mori: Komatsu maintains education systems organizedby occupational hierarchy and function on the basis of theunderlying concept of globalization that is Japan-based, notstateless.
Our management policy is to promote regionally recruitedemployees to manage regionally incorporated companies.
They are trained to understand and share the values of The
KOMATSU Way, as well as learning management strategy
through activities such as global management seminars.
A business-leadership training program is held in Japan tohelp executive candidates quickly grow into future company
leaders. This program will be extended to cover employees
at overseas affiliates in China and Russia. Sometimes evenyoung executives at our business partner companies takepart in the program.
We will continue to administer expert courses on global
construction equipment to foster after-sales service personnel leaders, conduct global technical competitions among
employees working in manufacturing, and promote peopleto-people exchanges between mother and child plants toconsolidate working abilities thorough on-the-job training atworksites, so that Japan s excellent tradition of manufacturing (Monozukuri) and technical skills will be disseminated tolocations overseas.

Komatsu has historically focused on developing
human resources, but what are some of the thecompany s recent initiatives?

Having the framework of The KOMATSU Way inplace, what organized approaches do you take todevelop human resources?

Developing People

Worksite cafeteria at the plant in Changzhou, China, refurbished in June
2011. Communication between employees and the company leads to an
improved work environment.

Further, skilled workers have been reaching mandatory
retirement ages in large numbers in recent years.
Under these circumstances, we have made urgent efforts
to convey the values of The KOMATSU Way to our newer
employees. As we pursue global operations, manufacturing
products and delivering services with consistent quality
across the world cannot be achieved if we all work differently from one another.
The KOMATSU Way is a statement of our strengths
and values that can be handed down from generation to
generation.
Today the scope of transmission of these values is nolonger confined to worksites in Japan, but extends globally.
That is why The KOMATSU Way was put into a statutory
formal document.
In practice, the values and concepts of The KOMATSU
Way are not learned by reading, but are acquired throughwork experience. We want employees to first experience
The KOMATSU Way in a real-life situation before consulting
a booklet. Thereby, they can develop experience and gradually come to understand the principles of The KOMATSU
Way.

Enhancing Quality of Lifearea.
In Japan, for example, because of the continuous reduction in the labor force due to declining birthrates and theaging population, it is important to provide an environment
where women and retirement-age employees can participate more actively.
In China, people talk about what is called Evolution
Space, which concer ns how much their career candevelop within the work to which they are committed.
Providing younger employees with such an environment
and improving the relevant personnel systems are thus very
important.
In light of this, I think one factor that is common throughout the world is, as I mentioned before, the importanceof respecting the personality and individuality of each
employee, creating opportunities where they can work insafe, comfortable and healthy ways and also find their jobs
to be rewarding. It may sound a little dramatic to talk about
global measures, but to give one example, we are presently
working on a plan to improve eating facilities for plant
workers. Eating is a great source of enjoyment for workers.
Now that we have completed the initial stage of investmentin production equipment, we are stepping up our efforts
to refurbish employee welfare services, such as worksite
cafeterias and the working environment.
From here on, we plan to take in the needs of employees
through daily communication with them.

The Mounting Demand for Natural
Resources and the Availability of
Human Resources in Africa
In 2011, as the world s population topped 7 billion people,
the planet is facing a serious challenge in ensuring a stablesupply of energy resources, as well as food and water.
Africa, a resource-rich continent, has undergone a boom
since the beginning of the century, thanks to the surging
prices of natural resources.
But, at the same time there are increasing demands forthe mining equipment needed to exploit those resources.
Consistent production of resources requires not only the
deployment of mining equipment, but also mechanics whoare qualified to service the machinery and keep it running.
In African nations with few local industries, customers
who own machinery increasingly depend on our distributors
to troubleshoot and service their machinery on a daily
basis because of the difficulty they have in hiring their own
mechanics. Our distributors are adding to their staff ofservice engineers, but they have a similar difficulty employing experienced personnel, making it an urgent task toprovide basic education on machine maintenance, as well
as securing the necessary human resources.

Training Centers in Collaboration withDistributors
Komatsu not only offers curricula and teaching materials
through our overseas affiliates to help distributors develop
human resources, we also give experienced engineers
direct access to more advanced training.
As part of our long-term commitment to training instructors and mechanics in the African region, we established
two Komatsu Training Centers, one in Dakar, Senegal in2009, and the other in Nairobi, Kenya in 2010. We are
steadily increasing support for the development of humanresources for our African distributors.
At these Training Centers, trainees are grouped into
teams of six, and receive one month of tutorials and twomonths of on-the-job training, which is repeated three times
over the course of a nine-month curriculum. As of March,
2012, 62 mechanics had completed the basic course.

substantial contributions to the project. Komatsu s training
facilities have been so highly acclaimed that there is a chancethat Komatsu may develop a partnership with the CFPT in the
future. It is our hope that this partnership will eventually extend
beyond the industrial field in Senegal, the key beneficiary of the

In rapidly developing strategic regions other than Africa,
where development of human resources is urgently needed,
we are arranging training classes in conjunction with local
private facilities.
In China, the number of mechanics on staff increased bymore than 900 in FY2010 compared to the previous year.
Estimates suggested that comparable increases in new
recruits would be needed in fiscal FY2011 and thereafter.
For this reason, we have been working to speed up thetraining of new mechanics by partnering not only withthe facilities at Komatsu and its distributors, but also with
universities and vocational colleges. One example of suchcollaboration is the expanding scope of a new employee
training program that has been pursued jointly with the
Shandong Jiaotong University in the Chinese Provinceof Shandong since FY2004. Under this program, newKomatsu service engineers, who come from all over China,acquire the basic concepts of construction equipment andmaintenance over a period of approximately six months.

the administration of the class after a request from JICA.
To prepare for the opening of class in October 2012, we
first need to cultivate instructors, so two JICA Instructors
are now undergoing training at the Komatsu Training Center
in Dakar. After the class begins, the Komatsu instructors willvisit from Dakar to conduct lessons and invite students to
Dakar to provide training with real machinery.
We would like to support local human resource development in this way, contributing to the increase of employment
opportunities, and enhancing the quality of human resource
development in the industry.

employees.

Enhancing Quality of Life

From the contents of The KOMATSU Way

The KOMATSU Way clearly defines the company s
guiding principles, cultivated by past generations and basedon the spirit of the company s founders. These include principles covering Komatsu s strength, attitude toward working
at Komatsu, and basic patterns of behavior. In FY2011,
five years after its formulation in 2006, we reviewed The
KOMATSU Way to make it more coherent and easier tounderstand, not only for Japanese employees, but also for
those at our overseas subsidiaries.
In addition, we created a Brand Management section
and added the CSR concept.
(Komatsu s initiatives in Brand Management are describedin more detail in the Special Story 1 on page 9)

http://www.komatsu.com/CompanyInfo/csr/2012/4-3.html

The KOMATSU Way was made easier to understand through the use ofnumerous illustrations. A small-size version that fits in the pocket of awork uniform was also issued. Comic books, videos and other awarenessraising tools are also available to bring home the message of
The KOMATSU way.

General Affairs and ComplianceKomatsu Ltd.

The importance of corporate social activities is
growing, worldwide.
Seki: When doing business, an enterprise must not only
operate safely and responsibly when it comes to theenvironment, but it is also essential that it maintain a socialrole within the local community.
Though Komatsu defines CSR activities as providing
social contributions through the use of our core technologies and resources, it also places a high value on local
community activities. First among these activities is supportand relief work in response to catastrophes, such as natural
disasters. When natural disasters, such as earthquakes,
tsunamis, hurricanes or floods strike, there is an urgent
need for construction and other equipment to restore
and reconstruct the disaster-stricken areas. At Komatsu,
regional plants and local subsidiaries have been among thefirst to identify the requirements of affected areas in times ofdisaster and deliver the needed equipment.
Another local activity we are engaged in is a project toremove anti-personnel landmines, utilizing technology and35

expertise developed through Komatsu s business activities.
In 2003, Komatsu embarked on the development of ademining machine, and since 2008 we have helped remove
landmines in Cambodia and Angola, in collaboration with
the Japan Mine Action Service (JMAS), a non-profit groupof demining specialists registered in Japan. Leveraging ourconstruction machinery, Komatsu has embarked on the
Safe Village Creation Project, which begins by making an
area secure using the demining machine, and then builds up
the necessary infrastructure for thecommunity - roads,
fields, schools andthe like.
One factor thatthese ongoing
activities have incommon is thatthey are based on
local community
needs.

Seki: For example, when considering the environmental
issues associated with the manufacture of a product, it is
now standard practice to estimate how much environmental
impact the product will cause throughout its lifecycle, frommaterial procurement and production to sales, operationand eventual disposal.

Growing with Society

We carry out CSR activities with our business
partners across the entire supply chain.

Seki: In FY2011, Komatsu revised our Worldwide Codeof Business Conduct, the framework of our complianceactivities.
Komatsu s Worldwide Code of Business Conduct is a collection of rules we abide by in business society. The revised
version of Komatsu s Worldwide Code of Business Conduct
not only defines the rules, laws and regulations that are
generally respected in business society, it expressly specifies being aware of CSR as an essential part of compliancewith these rules, to earn the trust of society.
The revision process involved a consciously global
perspective, and instead of simply revising a Japaneseversion and then translating it into English, we simultaneously reviewed both the English and Japanese versions
and made revisions that reflected opinions from around theworld. After the Code was released, it was translated into
numerous languages under the initiative of local subsidiaries, and it is now published in 14 languages in addition to
English and Japanese.
While The KOMATSU Way summarizes the values thathave been handed down through the Company s history, theWorldwide Code of Business Conduct asserts Komatsu sdetermination to coexist with broad segments of society asa good corporate citizen.
Komatsu will continue to update its Worldwide Codeof Business Conduct on a regular basis, to adapt to
evolving rules and social requirements. We will follow theseguidelines, together with the rules of the various countries
and regions in which we operate, while sharing our ideals
throughout the world.

How is Komatsu undertaking compliance?

Enhancing Quality of Life

Seki: To us, people in local communities are very important
stakeholders. Komatsu has a global network of manufacturing sites, offering opportunities for dialogue at individual
plants, briefing of local government and community representatives on the status of our corporate activities, andlistening to community needs.
In addition, Komatsu greatly values dialogue with its
stakeholders, which include business partners, employees,
shareholders and investors. Company leaders personallyattend global distributor conferences and assemblies of theMidori-kai, a group of our company s business partners
who support our production activities, to explain the detailsof Komatsu s business performance.
In the past, we relied on our daily marketing and sales
activities to offer opportunities for dialogue with our customers. Now, however, Komatsu has begun Brand Management Activities to promote integrated and well-organized
dialogue with customers on a global and companywide
basis (see page 9).
From a CSR perspective, we need to identify various
potential risks that may be difficult to recognize in thecourse of daily business activities, while also understandingsocial requirements from a global viewpoint and reflecting
these requirements in our management conduct. To thisend, Komatsu will strive to remain responsive, while working
closely with our various departments.

This also holds true as an approach to social issues. Not
only does Komatsu need to maintain a CSR mindset, but
all our business partners must work together with us in aconcerted effort to resolve issues.
Through ongoing communication and cooperation,
Komatsu has been working with our business partners
to solve environmental, safety and compliance issues
over a extended period of time. In FY2011, Komatsu
formulated the CSR Procurement Guidelines, a summary of
Komatsu s expectations from its suppliers, to define theirroles in a more codified manner.
The guidelines are based on Komatsu s previous communications via the Worldwide Code of Business Conductand other means, to convey the conditions we require of
our suppliers. We plan to use the establishment of theseguidelines as an opportunity to pursue educational initiatives
and promote CSR activities throughout the supply chain.
Looking at the supply chain from a global perspective andbeginning with human rights issues, we recognize numerous tasks and risks that are on a different level from thosein Japan. Considering these issues, Komatsu will work with
our various internal departments to consolidate approaches
to addressing them.

The Need for Rehabilitation Programs
for Young Chilean People
The number of young people driven to crime throughpoverty and difficult domestic circumstances is a majorsocial issue in Chile. Once young people are involved in acrime, they often commit another, and become trapped ina vicious circle of repeat offences. In fact, 67% of people
arrested for robbery are repeat offenders, of which 30%
have a criminal record of at least five incidences.
Recognizing this as a significant problem, the governmentof Chile has been operating a group training rehabilitation
program that is designed to reintegrate into society those
who have served a term in prison. However, the program
has not been successful due to an inadequate budget.
This problem is not only a matter of concern for thegovernment, but it also affects employment in privatecompanies. That is why it has become an urgent matter forboth the public and private sectors to jointly collaborate toenhance the effectiveness of rehabilitation programs.

The result was that 7 out of the 10 members who participated in the program were hired by KCC. Considering thatthe overall success rate of rehabilitation programs in Chile is30%, this high success rate is noteworthy, and has received
widespread acclaim.

I have worked at Komatsu for seventeen years andcurrently I am the mentor for Richard Tapia. When KCC
started with the social reintegration project, a project leader
asked me if I could guide and support one of the young
people enrolled. I did not have any relevant experience, but
I understood that this was an important role and I decided toaccept the challenge.
The program was not an easy road to follow, but I was notalone. The first time I had a conflict with Richard, I realizedthat we came from separate worlds with completely different

values and interests. But, I also learned that if I could accept
his background, we would be able to understand one
another. I believe he must have felt the same way that I did at
the time. As time progressed, we got to know and trust eachother more and more.
As a result of our work and efforts, Richard adopted thediscipline that was required to comply with work schedules
and dress codes, and he learned communication skills thatat first were difficult for him. Once he completed his remedialcourses, Richard joined the Accounting area, where he got
along well with colleagues and also won the affection of his
supervisors.
We both learned from each other, building trust and mutual
respect. Currently Richard works in the Komatsu RemanCenter and talks about wanting to attend college next year.
I am very proud of him because he took advantage of theopportunity the company gave him, and I am sure he will
succeed in his life project. I am grateful for the opportunity
the company gave me to support Richard, because it was anexperience of growth and learning for me as well.

Support for Restoration
after the Earthquake DisasterIn response to the Great East Japan Earthquake, which
occurred on March 11, 2011, Komatsu immediately
launched support activities for the disaster-affected areas
by utilizing the assets of our core business.
One of the greatest challenges for the disaster areas has
been the removal of scattered debris and the restoration ofdamaged roads. Komatsu gathered construction equipment
and power generators used for such work from westernJapan and later from the entire country, and began lending
them for use in the disaster areas free of charge.
In April 2011, Komatsu established the Tohoku Operation
Department in Sendai, where employees, with the cooperation of local governments, quickly evaluated the needs ofthe disaster areas and organized a maintenance service
system, so that rented equipment would remain operable
and employees could continue providing needed support.
Reconstruction support valued at JPY 2,400 million is being
provided by Komatsu, mostly in the form of free of charge
rental equipment, forklifts, temporary housing, power generators and other supplies owned by the Komatsu Group.
Construction equipment provided free of charge amounts tomore than 250 vehicles, and approximately 670 employees
from the sales andsupport divisions

Industrial Recovery: Transition from

To support industrial recovery, Komatsu donated forklifts
to the NPO Signal of Hope . Approximately 60 forklifts are
currently in service. In addition, we established the Komatsu
Safety Training Center Miyagi Center, with Komatsu paying
half of the tuition fees, to train operators of construction
equipment, who are scarce in the disaster areas, and toprovide working opportunities for disaster victims. There
have already been more than 1,500 students who havetaken courses and participated in recovery and reconstruction activities in the disaster areas.
Komatsu is also aiding students, who will play importantroles in manufacturing in the future. Through the Instituteof National Colleges of Technology, Japan, Komatsu isproviding scholarships (named Komatsu Scholarships ) tostudents of national technical colleges in the Tohoku andNorthern Kanto Regions, which were stricken by the disaster.

Additionally, in collaboration with Rio Tinto, a mineralresource mining company and a Komatsu customer, wehave established the Rio Tinto-Komatsu Scholarship , andare providing scholarships to students at Tohoku University,a national university. We hope that these scholarshipstudents can overcome the disaster of the earthquake andgo on to productive academic careers.

Principal

On March 11, 2011, the Tohoku region fell victim to a major
earthquake and tsunami. At Sendai National College of Technology, one student enrolled at that time and one scheduled
to enroll lost their lives, 34 students had family members or
loved ones who were lost or unaccounted for, 54 had theirhomes totally destroyed, and the college buildings and grounds
were devastated. What concerned me the most was that
there would be students who would have to quit school for
economic reasons. But, thanks to tuition waivers, as well as
many charitable donations, scholarships, and other assistance,

Reconstruction has only just begun. We are still at thestage of clearing away debris, but there is no doubt that
more construction equipment will be needed once work
starts on restoring infrastructure such as embankments,
roads, and railway tracks. The Komatsu Group will continue
to mobilize our management resources to assist with thereconstruction of the disaster-stricken areas.

we were able to overcome these difficulties without a single
student being forced to give up his or her studies. Among thesedifferent forms of support, the Komatsu Scholarship, which
extends all the way to graduation, is the most comprehensive
assistance for students affected by the disaster. Reading
the essays written by the students, I learned that they were
plagued by worries about whether it would be alright for themto continue their studies, whether they would be placing too
big a burden on their parents, whether they would have regrets
for causing trouble for their families, and whether they should
quit college and get a job. But thanks to the scholarships, they
were able to both support themselves and go to school. They

Decontamination of Radioactive Material.

Growing with Society

Provision and Development of Hazardarea Compliant Construction Equipment

Enhancing Quality of Lifesent radio-controlled construction equipment to remove
rubble and debris. In addition, Komatsu s chemical-protective
vehicle came into immediate use during investigations of
the accident site. By making further improvements to thisvehicle, we also developed the NBC (Nuclear, Bio, Chemical)
reconnaissance vehicle, which was delivered in March 2012.
Regarding the critical issue of removing radioactive
materials before beginning reconstruction, there are strong
expectations for use of a computer-aided bulldozer thatutilizes ICT. With this bulldozer, the depth of soil to be
removed can be preset and the bulldozer can automatically
excavate the surface to a fixed depth, swiftly and safely,
removing radiation-contaminated soil with great precision
without depending on the skills of the operator.
With the help of such technologies, Komatsu will continue
to research and develop machinery capable of operating inhazardous areas.

40Together with Business Partners - Initiative for CSR Procurement Business partners that supply materials, parts and components are important in helping to sustain Komatsu’s manufacturing activities.
Komatsu encourages our business partners to abide by social norms, while working towards CSR procurement.

Enhancing Quality of Life

In August 2011, Komatsu established our CSR Procurement Guideline. Before that, we not only supported environmental and workplace safety-related activities, consistent
with our Green Procurement Guideline, but also promoted
the concept of CSR among our business partners, by callingfor compliance with legal and social codes that are compatible with Komatsu s Worldwide Code of Business Conductt.
In the future, Komatsu will encourage our business partners to be more aware of their social responsibilities, using
the CSR Procurement Guideline to accelerate CSR activities
throughout our supply chain.

activities have also begun at group companies. We would
like to launch similar approaches for our Midori-kai groups
overseas as well.
We have begun publishing CSR Communication, aperiodic journal that introduces specific examples of CSR
case studies to our domestic business partners. Since May
2011, CSR Communication has been posted twice a monthon a website dedicated to our business partners.

We are working to convey the concepts of CSR procurement to our business partners.

Midori-kai Group Formed
In September 2011, the Komatsu China Midorikai Group was formed by 59 Chinese business
partners. Overseas Midori-kai Groups have alreadybeen formed in North America (37 companies) andEurope (51 companies). Joining these groups andthe Japanese Midori-kai Group, the Chinese Midorikai Group was the fourth to be established.
As the pace of globalization and flexible manufacturing accelerates, relationships with our business
partners will grow in importance, not only from theviewpoint of sustaining product quality and reliability,
but also with regard to fulfillment of corporate
responsibility within our supply chain.

to approach CSR
activities as part of Scene at the Inaugural Meeting of theKomatsu China Midori-kai Groupa unified effort.

Removing Anti-Personnel Landmines
Using its expertise in construction equipment technology, Komatsu is supporting demining work in areas plagued by antipersonnel landmines. Komatsu also participates in community development projects to revitalize landmine-affected areas.

Developing People

Since 2008, Komatsu has been working jointly with theJapan Mine Action Service (JMAS), an incorporated nonprofit organization (NPO), on a community-development
project to demine and rebuild areas suffering damage fromanti-personnel landmines in Cambodia and Angola.
Komatsu provides demining machinery, developed throughour expertise in building construction equipment andMonozukuri (manufacturing) knowledge, at no charge.
After demining, we begin development of agricultural landon the safely deminedareas using our construction equipment.
We also implement
community rejuvenation and reconstruction
projects for digging
wells, building schools,
and repairing andbuilding roads andKomatsu Demining Machine

All the settlers families gathered at the meeting to fairly
receive shares of housing and land through the lottery.
One individual who built a home in the settlement
remarked, I am happy there are ponds and a school on
this new land, but what is most pleasing to me is that there
are no landmines. Hiscomment illustrates
Kiou・Chea Montrei Village before
how eager people areto find safe land thatis clear of landmines.
At present, more than
350 homes have been
built, turning a barren
minefield into a safe,
habitable village.
Starting withdemining operations
with such as these,
Kiou・Chea Montrei Village now
Komatsu will carry on
our work to rejuvenate

Removing Anti-Personnel Landmines

Turning a Minefield into a Safe Village
Growing with Society

Beginning in FY2009, reconstruction of a 160-ha minefieldin the Battambang Province, Cambodia was completed
over the course of two years. As the land was safely
demined and the infrastructure built, neighboring residents
began settling in to Kiou・Chea Montrei Village.
On June 15, a meeting was conducted in the schoolyardof the KOMATSU Primary School (officially known as the
KOMATSU Safety Village Primary School ), to hold aof an Inspection Tour by the Parties of the
Topics Destination
11th Conference of the Parties of the Ottawa Treaty (Cambodia)
Additionally, at the conference hall in the Cambodian
capital of Phnom Penh, a booth was set up jointly with
JMAS to present a video summary of our social contribution activities, from demining to regional rehabilitation.

Data

The 11th Conference of the Parties of the Ottawa
Treaty (Anti-Personnel Mine Ban Convention) hosted by
the United Nations was held in Cambodia from November 28 to December 2, 2011, and Kiou・Chea Montrei
Village, a project site implemented together with JMAS
was chosen as a destination to be visited by conference
attendees.
The tour took VIPs from around the world aboard
a helicopter to give them a first-hand look at how theland, once a minefield, was transformed into a settlement. The tour offered participating parties an excellent
opportunity to learn about our efforts, from demining todevelopment of infrastructure and establishment of asafe village.

Resulting from Business Activities for details on
the methods used to calculate amounts.
*Total emissions of waste are expressed as acomposite of the amount recycled (excluding
valuables) and the amount disposed.
*R ecycling rate is calculated by dividing theamount recycled (including valuables) by theamount generated (including valuables).
*Total emissions of BOD and COD are calculated
by multiplying the average concentration by theamount of wastewater.
