2. History
In December 1955, Japan Petroleum Exploration Co., Ltd. was founded as a special company under the Law of Japan Petroleum
Exploration Co., Ltd. In October, 1967, when Japan Petroleum Development Corporation (JPDC) was founded, this special
company was dissolved with all of its goodwill invested into JPDC. The business activities of this special company were
continued as a division of JPDC. This form of business operation was implemented as a three-year time-limited measure as set

Item 2. Overview of Business
1. Management Policy, Business Environment, and Issues to be Addressed
Please note that any forward-looking statements in the following discussion are based on the judgement of the JAPEX Group’s
management as of the end of the fiscal year under review.
(1) Basic management policies of JAPEXAs a company focusing mainly on the exploration, development, production, and distribution of oil and natural gas, with themission of contributing to stable supply of energy in Japan through securing reserves and expanding production, the JAPEXGroup has established its business foundation by continuously discovering new oil and gas reserves, since its foundation in1955.
As the JAPEX Group’s supply volume increases, its social responsibility for stable supply of energy is growing. Meanwhile, it
has become crucial for the Group to build a new business model based on, among other things, irreversible changes in theenergy supply and demand structure driven by the progress in global decarbonization. Therefore, JAPEX aims to develop as acompany with market competitiveness whilst adapting to changes in its business environment. Our corporate vision is asfollows:
Contribute to society through stable supply of energy and address social issues towards Sustainable Development Goals- Explore, develop, produce and distribute crude oil and natural gas at home and abroad.
- Further strengthen the natural gas supply chain, built on our domestic infrastructures, by combining the electric power
supply business.
- Contribute to resolving energy and climate change related challenges towards a sustainable society through developing andcommercializing new technologies, drawing on our expertise.
- Achieve sustainable growth and maximize corporate value, while placing top priority on maintaining trust with all
stakeholders.
(2) Medium- to long-term management strategies and issues to be addressed
In light of irreversible changes in energy supply and demand structure driven by the progress in global decarbonization, in May
2021, JAPEX formulated and announced the JAPEX 2050, which outlines our responsibility and focus area the carbon-neutral
society.
In addition, in March 2022, we formulated and announced the “JAPEX Management Plan 2022–2030,” which sets forth abasic policy of improving profitability and building a business foundation for 2030 and beyond.
Outlines of “JAPEX2050” and “JAPEX Management Plan 2022–2030” are as follows.
[JAPEX2050]
1) GHG emission reduction target(a) Achieve net-zero emissions (Scope1 + Scope2) from JAPEX operations in 2050
As a first step, reduce the CO2 emission intensity of JAPEX operations by 40% in FY2030 compared to FY2019.
Note: Scope1: Direct emission of greenhouse effect gas generated from emission sources owned or managed bycompanies or households
Scope2: Indirect emission of greenhouse effect gas accompanying use of electricity, steam and heat(b) Strengthen line of business that contribute to the reduction of our supply chain emissions (Scope3)
Contribute to establish new technologies and energy supply with lower environmental impact, for reducing net CO2
emissions in our supply chain.
Note: Scope3: Indirect emission in supply chain except cases of Scope22) Focused efforts to realize a carbon-neutral society(a) Turn Carbon Neutral into a profitable business based on CO2 injection and storage technology
Aim to achieve the early implementation and commercialization of CCS (Carbon dioxide Capture and Storage)/CCUS(Carbon dioxide Capture, Utilization, and Storage) as a pioneer in Japan.

- 13 -

- Make the most of JAPEX strengths accumulated through oil and natural gas E&P in exploring and selecting candidate
sites (deep saline aquifers), drilling injection wells, and monitoring stored CO2.
Note: Deep saline aquifer: Sandstone layer in deep underground that includes ancient sea water (salt water) which are
not suitable for drinking. Its geographical distributions are broader compared to oil and natural gas reservoirs, andCO2 storage capacity is anticipated.
- Make contributions to CO2 transportation by leveraging our experience and expertise in natural gas and LNG(liquefied natural gas) supply.
Strive to collaborate and enter into carbon-neutral businesses areas, where synergies with CCS and CCUS can be
expected.
- Focus on BECCS (Bio-energy with Carbon Capture and Storage) and natural gas-fired power plants with CCS as
assumed areas of collaboration- Consider entering into business areas of carbon-recycling, including blue hydrogen and methanation.
(b) Expand participation in renewable energy projects
Aim to increase renewable energy projects in which JAPEX participates while utilizing knowledge and experience inconventional businesses.
- Increase the business opportunities and examine commercialization, mainly in biomass power generation leveraging
experiences in natural gas power generation business and offshore wind power generation which have an affinity withknowledge and experience of E&P.
(c) Stable supply of oil and natural gas
Recognizing that oil and natural gas will remain as one of the major energy sources worldwide, continue to meet thedemand for them.
As a comprehensive energy company, aim to achieve a carbon-neutral society through the use of CCS/CCUS and otherdecarbonization technologies, rather than through a complete shift away from oil and natural gas.
- Participate in natural gas development projects and consider employing CCS/CCUS in them.
- Horizontally deploy various supply methods for natural gas and LNG to meet demand for fuel switching from coaland heavy oil.
[JAPEX Management Plan 2022–2030]
1) Basic policy
Improve profitability and build business foundation for 2030 and beyond- Aim to achieve a reasonable profit level considering capital costs and enhance shareholder returns by focusing onpriority items in the business fields of E&P, Infrastructure/Utility, and Carbon Neutral.
2) Management goals(a) Quantitative targets- Business profit: ¥50 billion scale as of FY2030 (Interim target: ¥30 billion scale as of FY2026)- ROE: 8% as of FY2030 (Interim target: 5% as of FY2026)- Profit composition target on E&P-to-non E&Ps: 5-to-5 as of FY2030 (Interim target: 6-to-4 as of FY2026)
Note: Business profit: The figure is calculated by subtracting head office administrative expenses and other expenses
of approximately ¥6 billion from the sum of operating profit and share of profit of entities accounted for using
equity method (including profits to be distributed under limited partnership and silent partnership agreements)
in each business field. The forecast crude oil price used in this calculation is JCC US$50 per barrel.
(b) Carbon neutral related target- Launch CCS/CCUS hub & cluster model business utilizing our existing domestic oil and gas fields and others by
FY2030- 14 -

- Reduce GHG emission intensity of JAPEX operations by 40% in FY2030 compared to FY2019
3) Fund allocation- Out of a total of ¥500 billion in cash inflows, allocate ¥450 billion in growth investments and ¥50 billion in shareholder
returns4) Profit targets and priority items of each business field(a) E&P field
Contribute to early expansion of profit scale and respond to low-carbonization- Business profit target: ¥27 billion as of FY2030 (Interim target: ¥23 billion as of FY2026)- Priority items
Domestic: Conduct stable production of oil and natural gas in existing oil and gas fields, pursue additional
development at existing oil and gas fields and their surrounding areas, and reduce GHG emissions at
oil and gas production locations
Overseas: Steadily promote existing projects and acquire new interests(b) Infrastructure/Utility field
Transform business structure to withstand market changes such as oil price volatility- Business profit target: ¥27 billion as of FY2030 (Interim target: ¥12 billion as of FY2026)- Priority items
Domestic: Maintain and expand gas supply volumes, continue stable operations of FGP power plant, make steadyprogress in on-going development projects of renewable energy, and participate in additional projects
Overseas: Participate in an LNG supply infrastructure development project and consider possible participation in
renewable energy projects
Note: FGP: Abbreviation of Fukushima Gas Power Co., Ltd. managing Fukushima Natural Gas Power Plant (ourinvestment ratio of 33%)(c) Carbon Neutral field
Contribute to smooth transition for a carbon-neural society in 2050
- Business profit target: ¥2 billion as of FY2030 (Interim target: ¥1 billion as of FY2026)- Priority items
Domestic: Launch CCS/CCUS hub and cluster model business utilizing existing oil and gas fields and others
Overseas: Participate in CCS projects in systematically advanced areas and participate in feasibility studies on
CCS/CCUS in emerging countries5) Return to shareholders
Our basic shareholder return policy is to pay dividends in line with our financial results each fiscal year, with a target
consolidated dividend payout ratio of 30% starting from interim and year-end dividends of the fiscal year ending March 31,
2023. At the same time, we will do our utmost to maintain an annual dividend of ¥50 per share, even if we suffer from a
temporary setback in our business performance due to changes in the business environment and other factors. (However,for a fiscal year in which a drastic change in profit attributable to owners of parent is recorded due to extraordinary income
or losses and other special factors, the amount of dividends will be determined in consideration of such impact.)
By steadily implementing “JAPEX 2050” and “JAPEX Management Plan 2022–2030,” we will continue to contribute to therealization of a carbon-neutral society in 2050 and further increase our growth and corporate value as a comprehensive energy
company.

2. Views and Initiatives on Sustainability
Please note that any forward-looking statements in the following discussion are based on JAPEX’s judgement as of the filing dateof this Annual Securities Report.
(1) Basic views and initiatives
JAPEX believes that our mission is to provide a stable supply of energy and that our business activities themselves are a form ofCSR. Under this recognition, we have been promoting sustainability activities based on a policy on sustainability activities,
which is to actively work on solving social issues toward the realization of a sustainable society, and the five core CSR themes“SHINE” to realize value creation in the medium- to long-term. Every year, we establish CSR action plans in line with the core
themes and individual challenges. The Sustainability Committee over which the President presides implements a PDCA cycle
by reviewing the achievement progress and setting goals for the following fiscal year.
In 2023, we have defined the "Materiality" as what connects core CSR themes “SHINE” and our management plan.
“Materiality” has identified the four issues from the core CSR themes “SHINE” as what to work on now for our sustainablegrowth.
The correlation between the five core CSR themes “SHINE” and the four issues of Materiality is as follows:

• “Stable energy supply” corresponds to matters related to development of crude oil and natural gas that are covered by theindividual challenge (1).
• “Establishment of CN business” corresponds to matters related to CCS/CCUS that are covered by the individual challenges (2)and (3).
• “Promotion of HR development and diversity” corresponds to development of human resources, diversity and matters related
thereto that are covered by the individual challenges (11) and (12). While the individual challenge (11) was heretofore presented as“Respecting employee diversity and developing human resources,” it has now been modified to “Promotion of HR development- 16 -

and diversity” to conform to the presentation for Materiality.
• “Digital transformation (DX)” corresponds to all individual challenges of SHINE, but to the individual challenges of (1) and (12)with respect to specific stated goals.
Details of issues of Materiality are as follows. We will publicize the progress of Materiality on our website and integrated reports,
as necessary.
<Issues for contributing to society through our business>
Stable energy supply• We consider that oil and natural gas will continue to be indispensable energy sources for society even in a carbon neutrality
by 2050• Based on this consideration, we will continue to work for stable energy supply through the oil and natural gas development
Establishment of CN business• In order to realize a stable energy supply even in the future, we will contribute to the carbon-neutral society by establishing
CCS and others as our business.
<Strengthening of Management Foundation>
Promotion of HR development and diversity• We consider that human resources (HR) are an origin of the value creation and an essential for the realization of ourmanagement plan
• Based on this consideration, we will enhance the ability of each employee for value creation through HR development andstrengthen the company-wide capabilities through diversity promotion
Digital transformation (DX)• We will realize the working environment for add-valued businesses through the strategic utilization of data and digitaltechnologies and make continuous challenges for further increasing our corporate value.
(2) Climate change
JAPEX positions climate change response as one of its top management priorities. Aiming to contribute to global initiatives on
climate change and the government’s goal of achieving carbon neutrality by 2050, the entire JAPEX Group, including
subsidiaries and associates, is working to transform its business portfolio by reducing GHG emissions and developing CCS andother new technologies.
<Governance>
We have built a system for appropriate decision-making under the supervision of the Board of Directors. Key matters forbusiness execution, including climate change response, are deliberated at the Executive Committee and various othercommittees before being resolved by or reported to the Board of Directors. Key matters for execution, including climate change
response and other medium- to long-term policies and plans, are subject to resolution by the Board of Directors. The“JAPEX2050: Toward a Carbon-Neutral Society” (JAPEX2050) and “JAPEX Management Plan 2022–2030” were all matters
resolved by the Board of Directors. In addition, the progress toward GHG emission reduction targets, ESG external evaluation
results, ESG activity status, and other such information are reported annually to the Board of Directors. Climate change
response is also addressed by the Sustainability Committee, Risk Management Committee, and Investment Evaluation
Committee in addition to the Executive Committee. We have created a PDCA cycle for climate change response throughdeliberations at and reports to various committees as well as data collaboration and integrated management among businessdivisions and various committees.
In fiscal 2021, we prepared a skills matrix that lists the knowledge, experience, and skills of each of our Directors and Audit &Supervisory Board Members. In this matrix, we specified ESG and sustainability skills as items.

- 17 -

<Strategy>
Because of the business characteristics of handling fossil resources, JAPEX has positioned climate change response as a key matterin the consideration of business strategies. We conduct scenario analyses to evaluate the medium- to long term impact that climatechange will have on JAPEX’s business. In formulating “JAPEX Management Plan 2022–2030” in March 2022, we conducted afinancial impact analysis under four scenarios, more scenarios than usual, to evaluate the impact of climate change risks will haveon our medium- to long-term earnings in more details. Specifically, we conducted a scenario analysis using carbon and oil prices
published in the four scenarios (NZE*1, SDS*2, APS*3, and STEPS*4) presented in the World Energy Outlook (WEO) of theInternational Energy Agency (IEA) as parameters and used the analysis results for the consideration of the new management planby the Sustainability Committee.
We have evaluated the percentage of investment allocated to risk assets on an ongoing basis from the perspective of climate change
and aim to formulate a sustainable business portfolio even under the NZE scenario with the most stringent conditions.
*1 Net Zero Emissions by 2050 Scenario*2 Sustainable Development Scenario*3 Announced Pledges Scenario*4 Stated Policies Scenario<Risk management>
JAPEX manages climate change risks within its integrated risk management, which is a process for identifying and assessing
company-wide risks. Within the risk matrix created by conducting a quantitative risk assessment based on the impact andprobability of risks, we positioned transition risks due to climate change as major risks with a large impact, and list them in “Item 2.
Overview of Business, 3. Business and Other Risks.”
In addition to reviewing the risk matrix mentioned above, the Risk Management Committee also confirms the progress toward
GHG emission reduction targets and manages risks of existing major projects. The Sustainability Committee addresses medium- tolong-term climate change risks, and the Investment Evaluation Committee manages climate change risks such as carbon taxes in theinvestment evaluation of new projects. In this way, we develop and maintain processes to manage diverse climate change risks.
<Metrics and targets>
We established a net zero target by 2050 and a fiscal 2030 target as a milestone for GHG emissions (Scope 1+2) in our own
operations.
• 2050: Achieve net zero- 18 -

• FY2030: Reduce GHG emissions (Scope 1+2) of emissions intensity (GHG emissions intensity*) in our operations by 40%
compared to fiscal 2019
* CO2 emissions (ton-CO2) per 1 terajoule (TJ) of energy supplied by JAPEXIn addition, regarding emissions in our own supply chain (Scope 3), we established qualitative targets where we aim to strengthenbusiness fields that contribute to emission reductions.
As presented in the following table, GHG emissions intensity in fiscal 2022 for Scope 1+2 was reduced by 11% from fiscal 2019,
being less reduced compared to the previous year. The main reasons were a decrease in sales of domestic crude oil and natural gas(a decrease in intensity denominator) and an increase in GHG emissions due to emissions resulting from a failure of production
facilities and other reasons (an increase in intensity numerator).

(3) Human capital<Strategy>
JAPEX has defined basic approaches to support its human resources strategy to achieve growth to a comprehensive energy
company based on “JAPEX Management Plan 2022–2030.” We have established “Human Resources Development Policy” and“Internal Environment Development Policy” to develop environment for corporate and employee conduct and human resources
development, as well as “JAPEX Diversity, Equity & Inclusion (DE&I) Policy” to ensure diversity in human resources. We also
have established “JAPEX Health Management Declaration” to promote heath management under a system managed by the
President.
Based on these approaches, we have implemented various measures.
[Human Resources Development Policy]
With a view to achieve sustainable growth to a comprehensive energy company, JAPEX and employees shall engage in thefollowing activities:
1. Employees demonstrate their abilities as independent professionals who respond flexibly to changes and achieve theirpersonal growth through contributing to JAPEX’s business.
2. JAPEX provides employees with growth opportunities to develop human resources who can try to resolve technical andsocial challenges on energy issues and climate change.
[Internal Environment Development Policy]
JAPEX shall engage in the following activities to provide an environment to develop human resources:
1. Provide employees with job opportunities to try to achieve new higher goals for sustainable growth.
2. Support employees’ career growth so that they can improve their knowledge and experience to demonstrate their abilities tothe fullest extent.
3. Create an environment in which all employees can actively engage in their work by making the best use of theirpersonalities and feel that their work are satisfying and meaningful.
4. Foster a corporate culture in which all employees learn and grow on their own initiative.
[JAPEX Diversity, Equity & Inclusion (DE&I) Policy]
In order to respond to changes in the business environment and achieve further growth as a comprehensive energy company,
we regard the promotion of diversity, equity and inclusion (DE&I) as an important management issue, and aim to strengthen
our corporate competitiveness and achieve sustainable development. To this end, we enable our diverse employees to create
new value by encouraging each and every one to play their active role and grow their careers through fully demonstrating theirinherent capabilities.
By respecting diversity in terms of gender, nationality, age, disability, career, personality, and values, and by correcting social- 19 -

imbalances caused by these characteristics and differences, we will realize an organizational culture in which all employees
can be productive and active.
(1) Foster an organizational culture that makes the most of diversity
We seek to improve productivity and create innovation by fostering an organizational culture that makes the most of theirindividual characteristics and qualities of all employees, with positively accepting diversity and respecting differences.
(2) Promote the activities of diverse human resources
By securing outstanding talents regardless of gender, nationality, age, etc., and by providing timely and appropriate placement
and training as well as providing support for career and skill development tailored to each employee, we put in place a systemthat allows all human resources to demonstrate their capabilities and play their active role as self-directed professionals,
thereby increasing individual engagement.
(3) Create an environment that respects diversity
We promote the development of a work environment that allows employees to exert themselves to the fullest in all situations,taking into consideration the circumstances and characteristics of each individual, including childcare, nursing care,disabilities, and LGBTQ+.
[JAPEX Health Management Declaration]
The JAPEX group has the mission for stable energy supply and making social contributions by our business. Aiming to realize
our sustainable growth and value maximization based on the mission, Health, Safety, and Environment (HSE) is the top
priority in our business actions.
With understanding that each employee's health is essential for sustainable growth and value maximization, JAPEX declares topromote health management.
• Always be conscious of occupational safety and health and strive to ensure it and prevent industrial accidents.
• Create a comfortable work environment for better health both physically and mentally, including promoting work-lifebalance.
• Respect the diversity in values, individuality, and privacy and prevent discrimination and harassment.
• Promote physical and mental health in cooperation with the health insurance association and the labor union so that
employees and their families can live healthily for longer years.
<Major initiatives for the fiscal year ended March 31, 2023>• Matters regarding human resources development
JAPEX has launched the reskilling program for human resources development to promote DX and shift to new business fields witha view to achieving “JAPEX Management Plan 2022-2030.” For the DX basic education, we aim to create an organizational cultureof autonomous learning by providing education to all employees, including Directors and other officers and supporting them when
they obtain related qualifications. We also have launched programs aiming at improving expertise to develop human resources who
promote new business. In addition, we have newly established our internal university (JAPEX University) that plans support for
employees’ personal growth and career development through their independent and self-motivated learning and systematicallydevelops educational contents, mainly including lecture videos provided by internal lecturers.
• Matters regarding career development
To support employees in independently planning and achieving their career, we have internally disclosed the Guidelines forOperations specifying operations and requirements of each division at JAPEX, as well as working to enhance an internal personnel
recruitment system. In addition, we have a system to provide private consultation in place by setting up a consultation desk, as wellas providing career training by age group. Furthermore, we have internally disclosed the career of officers and managers, etc. anddeveloped a system where any employee can directly consult such Directors and other officers if he/she wishes.
• Matters regarding the promotion of diversity
To ensure diverse range of perspectives and views that would lead to the achievement of “JAPEX Management Plan 2022-2030,”
we have actively employed mid-career employees with diverse experiences and worked to promote them to managers so that they
will be appointed to key positions. For the promotion of women’s activities, we have set targets for the percentages of female newgraduates hired and female employees promoted to management positions, considering the total number of employees in relative- 20 -

shortage and the number of management positions as an important issue. In addition, to create a working environment where
diverse human resources can play an active role, we are committed to promoting a variety of ways of working that are tailored tothe individual circumstances of each employee. We have introduced a telecommuting system and a full flextime system, as well asa principle that transfers involving relocation must be consented by the employee. We are also making efforts to encourage male
employees to take childcare leave, aiming at creating an organizational culture where the taking of childcare leave is actively
encouraged. On top of the foregoing initiatives, we launched unconscious bias training for managers several years ago to remove abottleneck in the promotion of diversity and provided the training more widely to all employees, including general employees in thefiscal year ended March 31, 2023.
• Matters regarding the maintenance and improvement of employees’ health
JAPEX has established the JAPEX Health Management Declaration and to promote it under the responsibility of the President
based on the idea that consideration for the health of employees contributes to the growth and sustainable developments of thecompany. In the fiscal year ended March 31, 2023, based on the results of health checkups and health surveys, we have focused on
the three major health issues that we regard as important—“improvement of lifestyle,” “smoking cessation,” and “women’s healthissues.” We are enhancing our efforts for the maintenance and improvement of employees’ health by measures such as adopting asystem for employees to manage the results of their health checkups and health related data at any time and e-Learning for healthissues, setting a non-smoking time to restrict smoking during working hours and in the office, providing corporate support forpurchasing quit-smoking products, providing all employees with seminars related to female-specific cancers.

(4) Respect for human rights
In working on solving social issues toward the realization of a sustainable society, JAPEX has established the Human Rights
Policy, which defines its basic stance of promoting respect for human rights of stakeholders involved in our business activities
throughout its value chain under the JAPEX Group Code of Ethics and Conduct. As part of the human rights due diligence in
FY2022, we analyzed current status and extracted challenges for our efforts to respect human rights. We will endeavor to ensure
respect for human rights of stakeholders involved in our business activities by continuously implementing human rights due
diligence in FY2023 and thereafter, and implementing it more widely on the JAPEX Group companies and our value chain.
(5) Procurement policy
In working on solving social issues toward the realization of a sustainable society, JAPEX has established CSR Procurement
Policy, which defines its efforts on CSR elements in JAPEX Group’s procurement activities. In addition, by illustrating specific- 21 -

actions in CSR Procurement Policy to promote CSR procurement activities in concert with JAPEX Group’s suppliers, we ask themto understanding of, and to cooperate in the Policy to build a better partnership.

3. Business and Other Risks
The following risk information includes major items that may have an impact on the JAPEX Group’s operating results and financial
position. Recognizing the possibility of the occurrence of these risks, we strive to avoid their occurrence and to take appropriate
measures in the event of their occurrence.
JAPEX manages risks through the Management Risk Committee and other various internal committees. For further information,please refer to “Item 4. Information about Reporting Company, 4. Corporate Governance, (1) Overview of corporate governance, 3)
Other matters regarding corporate governance (Status of development of risk management system).”
The following risks are determined by JAPEX as major risks after discussions at the Management Risk Committee and the Board of
Directors meetings. The operating results and financial position of the JAPEX Group may be affected by risks that are not listed
below. This section contains forward-looking statements based on the judgment of JAPEX’s management as of the filing date.
(1) Risks related to commodity prices and exchange rates
1) Fluctuation risks in crude oil and natural gas prices
The JAPEX Group is engaged in the E&P Business in Japan and overseas and the Infrastructure/Utility Business in Japan.
The net sales and operating profit of these businesses are significantly affected by fluctuations in crude oil and natural gas
prices.
For example, our operating profit for the fiscal year ending March 31, 2024 is estimated to increase or decrease by ¥470
million when the oil price increases or decreases by US$1 per barrel. This increase or decrease includes the impact of changes
in the procurement cost of LNG, which is linked to the price of crude oil, and resulting changes in sales prices of domestic
natural gas and electricity. However, actual operating profit will be affected by a variety of factors other than those mentioned
above.
If the carrying amount of business assets at that point in time is not expected to be recovered from future profits due to a
reduction in the estimated medium- to long-term sales prices of crude oil, natural gas, etc., an impairment loss will berecorded for the assets, which may have a negative impact on the financial position and operating results of the JAPEXGroup.
2) Exchange rate fluctuation risks
Fluctuations in the exchange rate between the US dollar and Japanese yen have an impact on net sales and operating profit,
etc., because the JAPEX Group sells crude oil and natural gas produced in Japan in yen-denominated terms that refer to thecustoms clearance price (CIF price) of crude oil and LNG. Such fluctuations will also affect the domestic sales prices ofnatural gas made from imported LNG and electricity fueled by imported LNG and will affect the purchase prices as well.
Our operating profit for the fiscal year ending March 31, 2024 is estimated to increase or decrease by ¥570 million when theexchange rate increases or decreases by ¥1/US dollar.
(2) Risks related to business[E&P Business]
1) Risks related to E&P business investment (exploration and development investment)
The general characteristics of our E&P businesses include the following investment-related risks.
(a) Risks related to exploration investment
In exploration activities, we first identify the geological structure of the target area by analyzing the geological conditions,strata, and geophysical exploration. If the area is evaluated as positive, we conduct exploratory drilling to confirm the extent
of the oil and gas reservoirs and the amount of resources. However, geological uncertainty cannot be eliminated even with therecent development of exploration technology. It is not always possible to discover crude oil and natural gas on the expectedscale. Therefore, due to the failure of exploration activities, we may not be able to recover the expenditures previously
invested, and we may incur investment losses.
(b) Risks related to development investment
When moving onto the development of oil and gas fields, we strive to make rational final investment decisions based on avariety of information and assumptions obtained at that time, such as the estimated amount of resources obtained through- 22 -

exploration activities, the construction and operating costs of wells, production and transportation facilities, and the estimatedsales prices of products. However, we may not be able to make a final investment decision due to a variety of factors,
including changes in equipment specifications as a result of subsequent detailed technical studies, price hikes in materials andservices required for development, delays in government approval procedures and drilling work, new geological problems in
the production stage, and declines in crude oil and natural gas prices. In addition, due to the same factors above, theprofitability of the business may become lower than expected at the time of the final investment decision. As a result,investment losses may be incurred due to the inability to recover expenditures previously invested.
(c) Risks related to future well abandonment
The JAPEX Group’s current production wells and fields need to be abandoned after the end of production. The Group records
the present value of the costs in relation to abandonments of wells and fields based on current estimates as asset retirement
obligations. In the future, if the estimated amount is expected to be insufficient due to changes in the abandonment plan,tightening of regulations, or soaring prices of materials and equipment, it may be necessary to increase the amount of asset
retirement obligations, which may have an adverse impact on the financial position and operating results of the JAPEXGroup. For details of asset retirement obligations, please refer to “Item 5. Financial Information, 1. Consolidated Financial
Statements, etc., (1) Consolidated financial statements, Notes to consolidated financial statements (Asset retirement
obligations).”(d) Risks due to long investment payback period
The E&P businesses require a long period of time and substantial investment in exploration phase, from the initial basic
survey to the discovery of resources through drilling, and in the development phase, which involves drilling of development
wells and construction of production and transportation facilities after the discovery of resources. Therefore, it usually takes along lead time from the start of a business to the recovery of investment and the contribution to profits. During this period,changes in the business environment may result in an increase in investment (including those resulting from delays indevelopment schedules), a decrease in demand, a decline in sales prices, an increase in operating costs, and fluctuations inforeign exchange rates, which may lower the profitability of the business. Such changes also may prevent the recovery of
expenditures previously incurred and result in investment losses.
(e) Risks related to reserves and production volume
In order to maintain and develop the E&P businesses, it is necessary to compensate for and expand reserves and production,
which will decrease in line with production activities, in the medium- to long- term through continuous acquisition of mineralrights, exploration and development efforts. However, due to the existence of the risks listed in “(a) Risks related to
exploration investment” through “(d) Risks due to long investment payback period” above, as well as the risks related tooverseas E&P businesses and risks related to climate change as described below, if such operations are not successful, theamount of reserves and production may decrease in the future, which may adversely affect the JAPEX Group’s operating
results.
Reserves are evaluated based on the quantity of oil and gas in surface form that is estimated to be economically andoperationally extractable from known oil and gas reservoirs at the time of evaluation based on geological and engineering
data. The quantity may be revised upward or downward according to review based on new data to be obtained in the future,changes in economic conditions, and changes in internationally recognized reserve definitions. For details, please refer to “4.
Management’s Discussion and Analysis of Financial Position, Operating Results and Cash Flows, (1) Overview of operating
results, (d) Reserves of the JAPEX Group.”2) Risks specific to overseas E&P business investment
In addition to the “1) Risks related to E&P business investment (exploration and development investment)” above, theoverseas E&P businesses have the following risks as a general trend.
(a) Country risk
Some of our overseas E&P businesses are conducted in regions with relatively high country risk. Political, economic, andsocial turmoil (including significant deterioration in public safety), changes in legislation, taxation systems, or policies inthese countries may adversely affect the smooth execution of the Group's overseas business.
(b) Partner risk

- 23 -

When a large amount of investment is required to carry out the business, or when there are high risks in terms of technology,
etc., we engage in joint business with other companies as partners, rather than with ourselves, in order to diversify funds andrisks.
In making decisions regarding joint ventures, each partner is generally granted voting rights according to the amount ofinterests held, and we have no controlling authority in joint ventures in which we hold only a minor share. As a result, ourintentions are not necessarily reflected in decisions on exploration and development plans, etc., and if such decisions are
made in a manner that is not in line with our interests, we may not be able to obtain expected profits. In addition, if somepartners withdraw from projects, smooth operation of the projects may be interfered with.
The major overseas E&P businesses in production that require a considerable amount of funds are as described in “3) Risks
related to major individual projects in overseas E&P businesses” below.
3) Risks related to major individual projects in overseas E&P businessesa) Iraq Garraf oil field development project
JAPEX has been participating in the development and production project in Garraf oil field located in the southern part of the
Republic of Iraq through its investment in a consolidated subsidiary Japex Garraf Ltd. (investment ratio at the end of the
fiscal year ended March 31, 2023: 55.00%), which holds 30% working interest in the project and provides 40% of funding.
JAPEX has been promoting development businesses jointly with the operator, PETRONAS Carigali Iraq Holding B.V. (thesubsidiary of PETRONAS).
The production started in August 2013, and the project is currently conducting additional development work under the final
development plan to increase crude oil production, while allocating the proceeds from the sale of collected crude oil to capital
investment.
The production volume, sales volume, and net sales and operating profit of the project may decrease due to the deteriorationof the political, social, and security situation in the country and the agreement of the OPEC to reduce production. In addition,in the event of an increase in costs, delays in development schedules, or a decrease in production, there may be a shortage ofcrude oil sales revenue to fund capital expenditures, resulting in an increase in JAPEX’s financial burden.
(b) Russia Sakhalin-1 Project
JAPEX has been participating in the development of crude oil and natural gas off the coast of Sakhalin Island, Russia (Russia
Sakhalin-1 Project) through its investment in Sakhalin Oil and Gas Development Co., Ltd. (investment ratio at the end of the
fiscal year ended March 31, 2023: 15.29%).
As for the production and sales of crude oil and gas in the Russia Sakhalin-1 Project, its operating profit is significantly
affected by fluctuations in crude oil and natural gas prices, as described in “(1) Risks related to commodity prices andexchange rates, 1) Fluctuation risks in crude oil and natural gas prices” above. Sakhalin Oil and Gas Development Co., Ltd. is
an important associate of JAPEX. If profit of Sakhalin Oil and Gas Development Co., Ltd. significantly decreases due to suchfactors, the JAPEX Group’s operating results may be adversely affected. Under the strained situation in Ukraine, a newcompany was formed by the government of the Russian Federation and succeeded to all rights and obligations under the
production sharing agreement. Sakhalin Oil and Gas Development Co., Ltd. has been approved by the government of theRussian Federation to subscribe for a proprietary equity in the new company in proportion to its participating interest. The
operating results of the JAPEX Group may be adversely affected if our business activities will be restrained for a long period
due to the impact of the economic sanction against Russia.
[Infrastructure/Utility Business]
1) Risks related to natural gas sales
From the perspective of mitigating the impact of various risks in our E&P businesses, JAPEX is working to expand thevolume of natural gas we handle as part of our infrastructure and utilities business. We are actively engaged in thedevelopment of demand by utilizing existing natural gas pipelines and supplying LNG from satellite terminals using tankers
and other vehicles for areas outside the pipelines reach. However, the Group's operating results may be adversely affected byfactors such as a decline in the current handling volume of natural gas (including the volume of transportation service forthird parties), a failure to develop new demand, or a decline in unit sales prices. These factors may be caused by a decrease inpopulation due to the declining birthrate and aging population, a decline in the utilization rate of customers' facilities, andintensifying competition with peer companies.
We are striving to procure LNG that will be required based on future sales volume projections by combining long-term- 24 -

contracts with spot contracts to ensure both stability in procurement and flexibility in response to demand fluctuations.
However, in the event of an unexpected decrease in demand, we may not be able to cope with the situation by simply
adjusting the amount of LNG procured through spot contracts, and may incur a payment under the take or pay clause in along-term contract for untaken LNG volumes or resell the LNG at a lower price.
Although we have taken measures such as appropriately transferring fluctuations in LNG procurement prices to sales prices,
we may not be able to transfer such fluctuations to sales prices sufficiently if the LNG procurement prices rise in a shortperiod of time. In such a case, there is a possibility that the JAPEX Group’s financial position and operating results may be
adversely affected.
2) Risks related to natural gas thermal power generation business
JAPEX has invested in Fukushima Gas Power Co., Ltd., the main promoter of the natural gas-fired power generation
business at Soma Port in Fukushima prefecture (investment ratio at the end of the fiscal year ended March 31, 2023:
33.30%), where we are engaged in the power generation business using the power generation capacity equivalent to theinvestment ratio.
We have concluded long-term sales contracts with several customers, mainly retailers, for a significant portion of theelectricity we take. However, the JAPEX Group’s operating results may be adversely affected in the event that a decrease inelectricity sales volume or sales unit price occurs in the future due to procurement of alternative power sources required for
dealing with power plant equipment trouble or intensified competition among power sources.
[Overall business]
1) Risks related to accidents and disasters
The JAPEX Group strives to maintain the integrity of its facilities (such as natural gas pipelines) and develop emergency
response measures including security systems and Business Continuity Plans (BCPs) for operations such as well drilling,
production and transportation of crude oil and natural gas, and storage, regasification, and transportation of LNG. However,
we cannot completely prevent the risk of human and property damage or the inability to operate oil and gas fields due tooperational accidents and disasters (including abnormal weather, earthquakes, and other natural disasters), the spread of
epidemics (pandemics), crime and terrorism (including cybersecurity-related ones). In such an event, not all of the damage iscovered by insurance. In addition to direct damage, it could result in secondary damage such as loss of income due tointerruption of sales, compensation for damage to customers to whom we are obligated to supply, compensation for damage
due to environmental pollution such as soil, air, water, and ocean, administrative punishment, and loss of public trust.
2) Risks related to infectious diseases such as COVID-19
While we regard that COVID-19 now has a lesser impact on economic activities in and outside Japan, the spread of any
infectious disease like COVID-19 or a new infectious disease that requires measures to be taken, such as urban blockades,declaration of a state of emergency, and priority measures to prevent the spread thereof, may reduce demand for oil, naturalgas, and electricity and, furthermore, may cause a decline in the prices of crude oil, natural gas, and electricity.
3) Risks related to climate change
Following the adoption of the Paris Agreement, efforts have been made worldwide to reduce greenhouse gases, which areconsidered to be the cause of climate change and global warming, and the movement toward the realization of a low-carbon
society is accelerating.
Recognizing the importance of responding to climate change, JAPEX has been implementing necessary measures in suchareas as governance, business strategies, risk management, and emissions management based on the TCFD recommendations.
Of the risks related to climate change, risks associated with the transition to a low-carbon or decarbonized society (policy andregulatory risks, technology risks, market risks, etc.) and physical risks due to natural disasters (acute risks caused by sudden
meteorological events including typhoons and chronic risks associated with long-term climate change including sea level rise)
may become apparent in the medium- to long- term. As a result, if climate change policies are strengthened in various
countries and environmental laws and regulations, including carbon taxes, are revised or newly introduced, there is apossibility that the JAPEX's business value may be damaged due to a decrease in domestic and overseas demand for oil andnatural gas, a prolonged slump in sales prices, and additional costs.
4) Risks related to acquisition of new projects and establishment of new businesses- 25 -

As described in “Item 2. Overview of Business, 1. Management Policy, Business Environment, and Issues to be Addressed,”in May 2021, JAPEX announced the “JAPEX2050.” It outlines our responsibilities and issues to be addressed to realize acarbon-neutral society, as well as our future actions and direction for our business development. Also, in March 2022, JAPEX
announced the “JAPEX Management Plan 2022–2030” as the medium- to long- term management plan with the aim oftransforming into the business structure set forth in “JAPEX2050.” The “JAPEX2050” and “JAPEX Management Plan 2022–
2030” state that we will work on the E&P field; Infrastructure/Utility field with a focus on the supply of renewable energy;
and other areas related to CCS (capture and storage of CO2) and CCUS (capture, utilization, and storage of CO2) as ourbusiness foundation. However, if these efforts do not lead to the acquisition of new projects or the establishment of new
businesses, it may adversely affect the JAPEX Group’s operating results.
3. Specific laws and regulations
1) Laws and regulations related to gas and electric utilities
As part of retail liberalization aimed at introducing the principle of competition in the Japanese gas and power industries, thebusiness acts have been revised repeatedly and new revisions of systems may be made in future. If such revision of legal
systems is made, it may bring an opportunity for the JAPEX Group to expand its business due to factors such as market
revitalization, but at the same time have an adverse effect on our business performance due to additional obligations to beborne or an intensified competition.
2) Other laws and regulations specific to the JAPEX Group’s business
Due to the nature of the Group's business, the Group's operations may impose various environmental burdens. The JAPEXGroup therefore has taken all necessary procedures, including the acquisition of licenses and approvals from regulatory
authorities, submission of notifications, and provision of product information to customers, in accordance with the Mine
Safety Act, High Pressure Gas Safety Act, and other relevant laws and regulations, in a legal and appropriate manner, and noserious problems have occurred to date. However, if the current laws and regulations are strengthened in line with increasing
global environmental awareness, an increase in costs related to additional facilities and operational measures could have anegative impact on the JAPEX Group’s business performance.
4. Risks associated with the variation in INPEX CORPORATION's stock priceAs of the end of the fiscal year ended March 31, 2023, JAPEX held 4.09% of the shares of INPEX CORPORATION. As ofthe end of the fiscal year under review, the balance of investment securities of the JAPEX Group was ¥115,940 million, of
which ¥74,664 million was for the shares of INPEX CORPORATION. If the stock price of the company fluctuates, it may
affect the financial position of the JAPEX Group.
5. JAPEX’s shares held by the government
In December 2003, JAPEX listed its shares on the First Section of the Tokyo Stock Exchange through a secondary offering ofsome of the shares held by the then Japan National Oil Corporation (JNOC). As a result, the percentage of shares held by the
JNOC declined from 65.74% to 49.94%.
With the abolition of JNOC, the remaining shares of JAPEX held by JNOC were transferred to the government (Minister of
Economy, Trade and Industry) on April 1, 2005 and then an equivalent of 15.94% of the shares were sold with a transfer dateof June 15, 2007. As a result, the percentage of shares held by the Minister was reduced to 34.00%. Thereafter, JAPEX
acquired treasury shares from November 2021 to August 2022 and canceled its treasury shares in September 2022, which
resulted in the percentage of shares held by the Minister being increased to 35.79% as of March 31, 2023.
The shares held by the Minister may be sold in the future, and timing, method, and quantity of such sale may have an impact
on the JAPEX's stock price.
There is a memorandum of understanding between the government and JAPEX regarding the holding of these shares. It statesthat JAPEX will consult with the government regarding “amendments to the articles of incorporation,” “changes in capital orissuance of corporate bonds,” “settlement of accounts and appropriation of retained earnings,” “transfer or acquisition of partor all of the operation,” “determination of candidates for directors,” and “matters that have a significant impact on assets orbusiness management.” This memorandum is managed in a manner that respects the independence of JAPEX’s management,
and the existence of the memorandum has never hindered JAPEX’s business or restricted the contents of its business.
6. Compliance- 26 -

The JAPEX Group must fulfill the following social responsibilities in conducting business in Japan and overseas.
(a) Compliance with laws and regulations
Comply with laws and regulations including the Companies Act, the Tax Act, the Financial Instruments and Exchange Act,
the Anti-Monopoly Act, the Labor Standards Act, environment-related laws, information security-related laws, anti-bribery
laws, the Mining Act, the Gas Business Act, and other business laws.
(b) Implementation of information security measures
Appropriately manage confidential information, including collected personal information, so as not to be leaked or used forother purposes in the course of business.
(c) Blocking unfair trade
Do not engage in unfair transactions such as bribery or giving benefits to anti-social forces.
(d) Respect for human rights
Do not engage in or participate in human rights violations throughout the supply chain, including discrimination, harassment,
forced or child labor, and unfair interference with the rights of indigenous peoples.
In order to fulfill these social responsibilities, the JAPEX Group strives to raise awareness of compliance and human rights
among its officers and employees through in-house training and other means. In addition to establishing internal rules andcommittees (please refer to “Item 4. Information about Reporting Company, 4. Corporate Governance, (1) Overview ofcorporate governance” below), we have established internal control systems for internal audits and financial reporting.
However, if JAPEX Group’s officers and employees conduct any illegal or improper activities, it may cause tangible damage,such as suspension of oil and gas production operations and incurrence of legal expenses, as well as intangible damage, suchas loss of public trust, which may have a negative impact on the JAPEX Group’s operating results.

4. Management’s Discussion and Analysis of Financial Position, Operating Results and Cash Flows(1) Overview of operating results
The overviews of the financial position, operating results and cash flows (hereinafter referred to as “operating results”) of
JAPEX Group (JAPEX, consolidates subsidiaries and equity-method associates of JAPEX) for the fiscal year ended March 31,
2023 are as follows.
(a) Overviews of financial position and operating results
In the fiscal year ended March 31, 2023, economic and social activities continued to normalize even amid the ongoing effectsof the novel coronavirus disease (COVID-19). However, there is concern that the contraction in the overseas economy caused
by global monetary tightening may have a negative effect on the Japanese economy.
The Japan Crude Cocktail (JCC) price rose from the upper $100s per barrel at the beginning of the fiscal year to the upper$110s per barrel in the first half of the fiscal year due to pressure on crude oil supply and demand caused by the crisis in
Ukraine. Thereafter, concern over slowing demand with the renewed spread of COVID-19 in China and concerns over the
impact of interest rate hikes by the U.S. Federal Reserve Board (FRB) led to a decline in prices, with the JCC price finishing
the fiscal year in the mid-$80 level.
In the currency exchange market, the yen started the fiscal year in the lower ¥120/US$ level, but the trend of yen depreciation
strengthened from the first half to the second half of the fiscal year. While the trend shifted to yen appreciation from January
onwards, the exchange rate was around the mid-¥130/US$ level at the end of the fiscal year. As a result, the JAPEX Group’s
average oil sales price for the fiscal year rose compared to the previous fiscal year.
On the other hand, the JAPEX Group faced a severe domestic market environment with respect to natural gas sales. In addition
to competition with prices of other oil products, that was due to continuing competition in the entire energy industry driven by
the full retail liberalization of electricity and gas.
In recent years, the business environment surrounding the JAPEX Group has changed significantly, including the accelerationof the global move toward decarbonization. To respond promptly and flexibly to these changes in the business environment, in
May 2021, we formulated and announced “JAPEX2050: Toward a Carbon-Neutral Society” which outlines the responsibilities
and challenges we must take in order to achieve global net-zero CO2 emissions by 2050, and the direction for JAPEX’s future
actions and business development, and then in March 2022, we formulated and announced the “JAPEX Management Plan
2022-2030,” which is based on the basic policy of improving profitability and building a business foundation for 2030 andbeyond. We are diligently promoting our businesses based on these plans.
During the fiscal year, net sales was ¥336,492 million, an increase of ¥87,351 million (+35.1%) year on year. Gross profit was¥96,111 million, an increase of ¥46,208 million (+92.6%) year on year. Main factors behind the year-on-year increase for net
sales and increase for gross profit include a rise in the selling prices of crude oil and natural gas in Japan as a result of therising price of crude oil and LNG, despite the absence of sales of diluted bitumen as a result of the transfer of all the shares ofJapan Canada Oil Sands Limited (JACOS) in the previous fiscal year, which had been a consolidated subsidiary to promote theoil sands project in Canada.
Exploration expenses was ¥2,885 million, an increase of ¥2,525 million (+702.0%) year on year. Selling, general andadministrative expenses was ¥31,139 million, an increase of ¥1,405 million (+4.7%) year on year. As a result, operating profit
was ¥62,085 million, an increase of ¥42,276 million (+213.4%) year on year.
Ordinary profit was ¥83,130 million, an increase of ¥39,456 million (+90.3%) year on year, due mainly to a recording of gain
on derivatives.
Profit before income taxes improved by ¥101,585 million year on year to ¥83,084 million (loss before income taxes of ¥18,501
million in the previous fiscal year) due mainly to the absence of loss on sale of shares of subsidiary resulting from the transfer
of all the shares in JACOS and loss on transfer of interests owned by JAPEX Montney Ltd. in the shale gas project of North
Montney Area in British Columbia, Canada, which were recorded the previous fiscal year. Profit attributable to owners ofparent improved by ¥98,383 million year on year to ¥67,394 million (loss attributable to owners of parent of ¥30,988 million in
the previous fiscal year).

Below is a breakdown of net sales.
(i) E&P BusinessNet sales from the E&P Business came to ¥56,063 million, a decrease of ¥17,359 million (-23.6%) year on year, mainly
due to the absence of the sales of diluted bitumen resulting from the transfer of all the shares of JACOS, despite a rise in
the selling price of crude oil.
(ii) Infrastructure/Utility BusinessNet sales from the Infrastructure/Utility Business came to ¥213,657 million, an increase of ¥93,812 million (+78.3%) year
on year. This was mainly the result of a rise in the selling prices due to the rising crude oil price and LNG price, despite
the decreased sales volume for natural gas (Japan) and electricity.
(iii) Other Businesses
Net sales from other businesses, such as the contract services (drilling and geological surveys, etc.), sale of oil products,
including liquefied petroleum gas (LPG), heavy oil and the like, as well as other subcontracted tasks, came to ¥66,771
million, an increase of ¥10,898 million (+19.5%) year on year.
Below is a summary of performance by segment (before elimination of intersegment transactions).
Japan
Net sales in the Japan segment are mainly composed of crude oil, natural gas (including LNG), electricity, contract services, oil
products and the like. In the fiscal year under review, net sales came to ¥303,047 million, an increase of ¥110,378 million(+57.3%) year on year, mainly due to higher sales prices of crude oil, natural gas, and electric power. Segment profit increasedby ¥44,115 million (+178.3%) year on year to ¥68,855 million, mainly due to improvements in balance of sales revenue
resulting from higher sales prices.
North America
Net sales in the North America segment are mainly composed of crude oil and natural gas (including diluted bitumen). In thefiscal year under review, net sales came to ¥9,161 million, a decrease of ¥24,652 million (-72.9%) year on year, due mainly tothe absence of the sales of diluted bitumen resulting from the transfer of all the shares of JACOS. Segment profit increased by¥2,420 million (+135.3%) year on year to ¥4,210 million, mainly due to improvements in balance of sales revenue resulting

Proved reserves held by the following consolidated subsidiaries include reserves attributable to non-controlling interests.
(Figures in parentheses are non-controlling interests’ percentage.)
Domestic: Japex Offshore Ltd. (29.39%)
Overseas: Japex Garraf Ltd. (45.00%)
2. Reserves of consolidated subsidiaries and equity-method associates whose balance sheet dates differ from theconsolidated balance sheet date are accounted for on the basis of the entity’s respective fiscal year-end.
3. Through its equity method affiliate Sakhalin Oil and Gas Development Co., Ltd. (SODECO), JAPEX has been
participating in the Sakhalin-1 Project. A new business entity Sakhalin-1 Limited Liability Company (hereinafter “S-1
LLC”) was established on October 14, 2022, pursuant to the Presidential Decree No. 723 of the Russian Federation on
October 7, 2022 and Governmental Decree No. 1808 of the Russian Federation on October 12, 2022, and the contractual
rights and obligations pursuant to the production sharing agreement were transferred to S-1 LLC. SODECO was approvedby the government of the Russian Federation to subscribe for a proprietary equity in the S-1 LLC, according to its 30%
interest in the Sakhalin 1 project. However, the reserves of SODECO are excluded from the above table because it isdifficult for us to obtain information to assess the reserves. The quantity reduced due to the exclusion is included in“Change due to revision of evaluation from the previous fiscal year” for the equity method affiliate.

Proved reserves detailed in the above table represent the quantity of oil and gas in surface form that is estimated to beeconomically and operationally extractable from known oil and gas reservoirs at the time of evaluation based on geological andengineering data. The figures do not include the past production volumes or resource volumes related to undiscovered deposits.
As for the definitions of reserves, the Petroleum Resources Management System (PRMS), which were established in 2007 byfour organizations, namely the Society of Petroleum Engineers (SPE), the World Petroleum Council (WPC), the American
Association of Petroleum Geologists (AAPG), and the Society of Petroleum Evaluation Engineers (SPEE), have been widely
accepted as an international standard.
The figures presented in the tables above are based on JAPEX’s own evaluations in accordance with the PRMS’ definition of“proved reserves,” which was revised in 2018. The figures do not include reserves corresponding to “probable reserves” or“possible reserves,” i.e., reserves that have higher uncertainty regarding future extractability than proved reserves under the
PRMS. Further, under the same definitions, projects for which commercial development plans have not been finalized (even if
the existence of resource deposits has been confirmed) are separately classified from reserves as “contingent resources.”
Accordingly, the figures presented on this table do not include the JAPEX Group’s contingent resources in areas lacking
finalized development plans.
We acknowledge that the definition of proved reserves used by the U.S. Securities and Exchange Commission (SEC) is also
widely accepted, especially among investors in the United States. The definition of proved reserves by the SEC isfundamentally similar to that under the PRMS.

- 35 -

JAPEX discloses the figures based on its own judgment in accordance with the PRMS’ definition of proved reserves.
Regarding the reserves held by overseas project companies, we disclose the figures based on the economic shares specified in
the contracts among each project company and authorities such as the local government.
In addition, Ryder Scott Company, L.P. has been contracted by JAPEX to conduct a third-party assessment and appraisal of thevalidity of JAPEX’s evaluation and judgement for the quantity equivalent to around 73% of the proved reserves of JAPEX andits consolidated subsidiaries in Japan as of March 31, 2023 (the quantity is hereinafter referred to as “[1]”) as disclosed on theabove table. Regarding the overseas reserves, reserves held by Japex (U.S.) Corp., JAPEX UK E&P Ltd. and Kangean Energy
Indonesia Ltd. are assessed by third parties. The sum total of domestic and overseas quantity is equivalent to around 47% of
the total proved reserves as of March 31, 2023 (the quantity is hereinafter referred to as “[2]”) as disclosed on the above table.
As the figures of proved reserves obtained by JAPEX’s own evaluation and those obtained by the third-party assessments
approximate, we believe that the former figures are appropriate.
Reserves are ultimately a projection of future production capacity shrouded in uncertainty. Nevertheless, JAPEX strives toensure accurate evaluations based on currently available scientific evidence, including geological and engineering data. Despite
these efforts, the quantity may be revised upward or downward according to review based on new data to be obtained in the
future, changes in economic conditions, and changes in the internationally accepted definitions for reserves.

(2) Management’s discussion and analysis of operating results and other relevant items
Views and issues analyzed/discussed with regard to the status of operating results and other relevant items from the
management’s perspective, are as follows.
Please note that any forward-looking statements in the following discussion are based on the judgement of the JAPEX Group’s
management as of the end of the fiscal year under review.
(a) Views and issues analyzed/discussed with regard to the financial position and the status of operating results and otherrelevant items
Profit attributable to owners of parent of the JAPEX Group for the fiscal year under review increased by ¥98.3 billion year on
year to ¥67.3 billion, as shown in Chart 1 “Main factors for changes in profit or loss for the fiscal year under review (YoY).”
Main factors for changes are analyzed per each line item profit as follows.
Chart 1: Main factors for changes in profit or loss for the fiscal year under review (YoY)(Operating profit: + ¥42.2 billion)
The main components of the increase of ¥42.2 billion in operating profit are as follows: an increase in operating profitof ¥21.0 billion each in the domestic E&P Business and the Infrastructure/Utility Business due to an increase in sales
prices of crude oil, natural gas and electricity.
(i) Overseas E&P Business
The overseas E&P Business mainly covers JUS projects in the North America segment and Japex Garraf projects in
the Middle East segment. While the North America segment included JACOS and JML projects in the previous fiscal
year, all shares of JACOS and all interest held by JML in the shale gas project were transferred in the previous fiscal
year.
A year-on-year decrease of ¥0.7 billion in operating profit of the overseas E&P Business was mainly due to adecrease of ¥1.8 billion in operating profit caused by the absence of JACOS’ operating profit recorded in theprevious year, all shares of which had been transferred and a decrease of ¥2.7 billion in Japex Garraf Ltd.’s operating
profit caused by a one-off cost, which were only partially offset by an increase of ¥4.0 billion in operating profit due
to factors such as an increase in oil production resulting from tight oil development project in which JUS has
participated.
(ii) Domestic E&P Business
The domestic E&P Business mainly covers production and sales activities for crude oil and natural gas conducted by
JAPEX and its consolidated subsidiary, Japex Offshore Ltd. Such activities are included in the Japan segment. Whilethe classification of crude oil (domestic) represents the sales for customers outside of the Group, natural gas(domestic) represents the deemed sales from transactions with the Infrastructure/Utility Business set for internal- 37 -

management purposes.
The domestic E&P Business recorded a operating profit increase of ¥21.0 billion mainly due to higher crude oil andnatural gas sales prices*. As shown in Chart 2 “Results of crude oil price and exchange rate (YoY),” JCC price rosefrom US$73.28 per barrel of the previous fiscal year to US$102.26 per barrel of the fiscal year under review, a yearon-year increase of US$28.98 per barrel (+39.5%), causing an increase in operating profit.
* Sales prices of natural gas (domestic) represents transaction prices of natural gas supplied from the domestic E&P
Business to the Infrastructure/Utility Business set for internal management purposes.

the former overseas subsidiary of JAPEX (until August 2021).

(iii) Infrastructure/Utility Business
The Infrastructure/Utility Business mainly covers the sale of natural gas (domestic natural gas and regasified LNG)
to customers in regions along JAPEX’s own gas pipeline network and the sale of LNG via a satellite supply systemusing tank trucks to meet demand for natural gas in the areas outside of its pipeline network, as well as the sale ofelectricity.
The Infrastructure/Utility Business recorded a year-on-year operating profit increase of ¥21.0 billion. This was due
mainly to the absence of a one-off factor in the previous fiscal year (an increase in cost arising from procurement ofalternative sources in a spot market due to production problems which happened in LNG suppliers), as well as therising sales prices of natural gas and electricity resulting from the rising average import price of LNG due to thesoaring of LNG spot prices.
Ordinary profit for the fiscal year under review was ¥83.1 billion, an increase of ¥39.4 billion (+90.3%) year on year. The
increase of ¥39.4 billion was due mainly to an increase in operating profit as mentioned above and a decrease in non-operating
income and expenses of ¥2.8 billion, as shown in Chart 1 “Main factors for changes in profit or loss for the fiscal year underreview (YoY).”(Non-operating income and expenses:(¥2.8 billion))
A year-on-year decrease of ¥4.6 billion in foreign exchange gains was due mainly to a decrease in foreign exchange
gains regarding JAPEX’s foreign currency denominated receivables and foreign currency deposit compared to theprevious fiscal year.
A year-on-year decrease of ¥7.1 billion in share of profit of entities accounted for using equity method was due mainly
to a decrease in sales volume of crude oil at Sakhalin Oil and Gas Development Co., Ltd.
A year-on-year increase of ¥8.9 billion in other non-operating income and expenses was due mainly to gain onderivatives of ¥6.0 billion generated from a book-out transaction of LNG (a transaction to sell back LNG at an agreed
market price without making physical exchange).
Profit before income taxes for the fiscal year under review increased by ¥101.5 billion year on year to ¥83.0 billion. As shownin Chart 1 “Main factors for changes in profit or loss for the fiscal year under review (YoY),” the ¥101.5 billion increase wasdue to the increase in ordinary profit as mentioned above and the increase of ¥62.1 billion in extraordinary items.
Extraordinary items increased due to the absence of loss on transfer of JML’s interests in the shale gas project of ¥44.7 billion- 38 -

and loss on sale of all the JACOS’ shares of ¥94.3 billion, both recorded in the previous fiscal year, which were partially offset
by the absence of gain on sale of investment securities of ¥39.8 billion recorded in the previous fiscal year resulting from thesale of a portion of strategic shareholdings.
Profit attributable to owners of parent for the fiscal year under review amounted to ¥67.3 billion, a year-on-year increase of¥98.3 billion. As shown in Chart 1 “Main factors for changes in profit or loss for the fiscal year under review (YoY),” the main
factors behind the increase of ¥98.3 billion were the above-mentioned increase in profit before income taxes, a decrease of ¥5.4
billion in profit due to an increase in income taxes, and an increase of ¥2.2 billion in profit (loss) attributable to non-controllinginterests.
The amount of total income taxes, obtained by “income taxes – current” plus “income taxes – deferred,” was ¥15.1 billion. The
increase in total income taxes was due mainly to an increase of ¥6.9 billion of income taxes – current resulting from asignificant increase in income at JAPEX. The amount of profit attributable to non-controlling interests was ¥0.5 billion for the
fiscal year under review. This was due mainly to a decrease in profit of Japex Garraf Ltd. for the fiscal year under review.
(b) Analysis and discussion of cash flow and capital resources and liquidity of funds(Basic policy)
In line with our financial discipline outlining a “debt-to-EBITDA ratio < 2,” we will secure funds necessary for business
continuity and new investment, keeping our financial soundness. Chart 3 “Changes in a debt-to-EBITDA ratio” shows thechange of the ratio from the previous fiscal year to the fiscal year under review.
In the fiscal year under review, interest-bearing debts increased mainly due to JAPEX’s debt guarantees of ¥4.3 billion on
borrowings from financial institutions of JAPEX’s associates, Abashiri Biomass Power 2 LLC. and Abashiri Biomass Power
3 LLC. We have, however, achieved a “debt-to-EBITDA ratio < 2” continuously from the previous fiscal year.

(Funding methodology)
The JAPEX Group efficiently uses internal funds and loans from banks to secure necessary funds to meet the funddemand.
While the Group’s working capital, etc. is primarily procured using internal funds, the Group has introduced a CMS (cashmanagement systems) in an effort to improve funding efficiency and secure liquidity of funding.
Foreign currencies for transactions such as purchase of LNG are exposed to foreign currency fluctuation risk. The Group
mitigates such risk by utilizing foreign exchange forward contracts.
We have entered into loan commitment agreements with multiple banks to facilitate efficient procurement of working
capital. The Group can borrow money in yen or US dollar under these agreements.
(Funding use and allocation)(i) Consolidated financial position and funds allocation policy
The JAPEX Group has planned to allocate ¥450.0 billion to growth investments in fields such as E&P,
Infrastructure/Utility, Carbon Neutral fields and ¥50.0 billion to shareholder returns for 9 years from FY2022 to FY2030,
as shown in Chart 4 “JAPEX Management Plan 2022-2030, allocation policy.” Also, we have determined to adopt a
consolidated dividend payout ratio for the basic policy for shareholder returns and to pay dividends in line with financial
results with a target payout ratio of 30%.
The Group has planned to raise funds for the above-mentioned funds allocation of ¥500.0 billion through cash flows fromoperating activities of ¥380.0 billion and cash on hand and bank loans of ¥120.0 billion.
Chart 4: JAPEX Management Plan 2022-2030, allocation policy(ii) Approach for funds on hand
While the E&P Business, in particular, requires a large amount of investment funds, it usually takes a long time from thestart of the business to recover the investment. During this time, the business is exposed to the risk of changes in businessenvironment. In light of such business characteristics, we have managed funds properly thorough methods such as
preparing monthly financial plans, in order to secure liquidity on hand necessary for the smooth business operation.
(c) Significant accounting estimates and assumptions
The Group’s consolidated financial statements are prepared based on accounting principles generally accepted in Japan. The
management of the Group prepares these consolidated financial statements based on their estimates, which affect assets andliabilities on the balance sheet date, and the amounts and disclosure of revenues and expenses during the reporting period
within the range of certain accounting principles. Although the appropriateness of these estimates is continuously assessed
based on past results and circumstances and reviewed, when necessary, they may differ from actual results due to uncertainties
inherent to estimates.
The Group’s highly uncertain accounting estimates for the fiscal year under review include that for the recoverability ofdeferred tax assets. The recoverability of deferred tax assets is largely dependent on estimates of future earned revenue andgenerated cash flow from the Group’s main operation activities. Especially this item receives a direct influence from market
conditions such as crude oil prices and foreign exchange, and estimates of reserves.
The above-mentioned significant accounting estimates and assumptions used for the preparation of the consolidated financial
statements, among other matters, are as stated in “Item 5. Financial Information, 1 Consolidated Financial Statements, etc., (1)Consolidated financial statements, Notes to consolidated financial statements, (Significant accounting estimates).”- 40 -

3. Dividend Policy
We aim to sustainably increase corporate value through proactive investment using retained earnings and expansion of ourbusiness base, thereby sharing the fruits of our efforts with our shareholders. JAPEX's basic policy for profit distribution is to pay
dividends in line with business results for each fiscal year with a target consolidated dividend payout ratio of 30%, while striving
to maintain an annual dividend of ¥50 per share even in the event of a temporary downturn in business performance due to factors
such as changes in the business environment. (However, in the year when profit attributable to owners of parent fluctuatessignificantly due to extraordinary income or loss or other exceptional factors, the amount of dividend will be determined inconsideration of such fluctuations.)
Based on this policy, we decided to pay a dividend of ¥370 (an interim dividend of ¥150 and year-end dividend of ¥220) per
share for the fiscal year under review.
Pursuant to Article 454, paragraph 5 of the Companies Act, our Articles of Incorporation stipulate that JAPEX may, by aresolution of the Board of Directors, pay an interim dividend on September 30 of each year as the record date. JAPEX pays
dividends twice a year as dividends of surplus: an interim dividend and a year-end dividend. The amount of interim dividend isresolved at the meeting of the Board of Directors, year-end dividend at a General Meeting of Shareholders.
Dividends of surplus for the fiscal year are as follows:

4. Corporate Governance(1) Overview of corporate governance1) Basic views on corporate governanceContributing to society through stable energy supply and addressing social issues toward realizing the sustainable
development goals is the corporate vision of JAPEX. In order to achieve the corporate vision and to maximize our corporate
value in a medium- and long-term perspective, the efficient and transparent corporate management and the building of mutual
trust relationships with our stakeholders including shareholders through ensuring our accountability are required, andcorporate governance is one of our important topics as the foundation.
2) Outline of corporate governance structure and reasons for adopting such structure(Outline of corporate governance)
At JAPEX, Directors and Executive Officers, who are appointed and assigned duties by the Representative Directors and theBoard of Directors, serve as operating officers. The Board of Directors and Audit & Supervisory Board Members, along with
the Audit & Supervisory Board that is comprised of all Audit & Supervisory Board Members, are responsible for supervising
the execution of their duties. (Company with an Audit & Supervisory Board)
The Board of Directors is held regularly once a month. Decisions on important business execution are left to the Board. It
also serves supervisory functions as it receives business execution reports from Directors or Executive Officers.
In addition, in order to strengthen the supervisory functions of the Board of Directors, JAPEX appointed five insightful andindependent Outside Directors. We actively listen to their opinions and advice on meeting agenda and deliberations, which

<Corporate Governance Structure>(Reasons for adopting the current corporate governance structure)
As stated above, JAPEX has put in place a structure where Outside Directors comment on and supervise the corporate
management by operating officers from an independent standpoint and audits on Directors’ performance of duties are
conducted by Audit & Supervisory Board Members, along with the Audit & Supervisory Board. Such structure has beenworking well and fully ensures objective and appropriate decision-making.

- 55 -

(Status of development of risk management system)
In order to adequately operate the internal control system, we have set up various internal committees and developed asystem for risk management. Management risks in general and risks associated with individual businesses are evaluated andmanaged by the Management Risk Committee from a cross-sectional perspective, and deliberated by specialized committees
to mitigate the risks. For example, Investment Evaluation Committee verifies risks and the appropriateness of investments inimportant projects. Once the investment decision was made for an individual project, the Management Risk Committeemonitors the progress of the project and formulates measures against challenges faced by the project.
In an attempt to realize sustainable growth in a medium-to -long run, the Sustainability Committee was established. It
deliberates on “JAPEX Management Plan 2022–2030,” as well as important managerial policies concerning environment,social and governance (ESG), including JAPEX’s cross-sectional policies to respond to climate change. In cases whenmatters related to business and other risks are raised for deliberation at the Committee, insights obtained from the activitiesof the Management Risk Committee and the Investment Evaluation Committee shall be reflected or utilized in the
deliberation as appropriate. JAPEX has also established specialized committees the Information Security Committee and the
Health, Safety, Security and Environment (HSSE) Committee to deliberate important issues concerning information security
and occupational health-and-safety, respectively.
Deliberation results and verification results obtained by these internal committees are reported to the Executive Committee
and the Board of Directors as needed before they discuss related matters.
(System to ensure appropriate business activities in subsidiaries)
The Auditing Dept. conducts internal audits on our subsidiaries based on annual audit plan to ensure appropriateness of theirbusiness activities. Audit results are reported to the President, then to Audit & Supervisory Board Members, and corrective
actions are taken as needed.
The Auditing Dept. evaluates on the development and operating status of subsidiaries’ overall internal control for financial
reporting, and the evaluation results are utilized in internal control audits conducted by the Accounting Auditor, and arereported to Audit & Supervisory Board Members and the Board of Directors of JAPEX.

Overview of the measures to prevent large-scale acquisition of our company’s shares (Takeover Defense Measures)(1) Basic policy regarding the person controlling decisions relative to policies for our finances and business
JAPEX considers that the person controlling our financial and business policy decisions should fully understand the content of
our finances and business and the source of our corporate value, and is eligible to protect and enhance corporate value andultimately the shareholders’ common interests in a continuing, sustainable manner.
JAPEX believes the decision on an acquisition proposal which is associated with the transfer of corporate control should- 57 -

ultimately be made based on the general decision of our shareholders. Furthermore, JAPEX does not disapprove of large-scale
share acquisition that contributes to our corporate value and ultimately the shareholders’ common interests.
Nevertheless, among large-scale share acquisitions, there are many that do not contribute to the corporate value and theshareholders’ common interests, in light of their purpose, including such that cause a clear infringement on the corporate value
and the shareholders’ common interests, such that has the risk of a de facto coercion against the shareholders to sell their shares,
such that does not provide sufficient time and/or information for the Board of Directors and the shareholders consideration of thecontent of the large-scale share acquisition or for the Board of Directors to propose an alternative plan, and such that requireconsultation and negotiation with the acquirer to draw out a more favorable condition than the conditions presented from theacquirer.
The large-scale share acquirer should understand the source of our corporate value, described in (2)1 below, not to mention thecontent of JAPEX’s finances and business, and unless he or she protects and enhances them over medium to long term, ourcorporate value and ultimately the shareholders’ common interests will be damaged.
JAPEX considers such a large-scale acquirer that does not contribute to our corporate value and the shareholders’ common
interests inappropriate as the controlling person to determine the policies of our finances and business, and thus consider
necessary to protect our corporate value and ultimately the shareholders’ common interests by taking essential and substantial
measures against such attempts.
(2) Special undertakings that contribute to the source of our corporate value and to the realization of the basic policy
1. Source of our corporate value
JAPEX has developed its business focusing on the improvement of the self-sufficiency of oil and natural gas since its foundationin 1955. Starting out with zero reserves, JAPEX has established its current business base in the compounding discoveries of newoil and gas fields one after another, and is operating the businesses of exploration, development and production, andtransportation and distribution of oil and natural gas resources as its core business.
The source of our corporate value lies in our business model where we conduct exploration, development, and distributing in
integrated manner, upon our ownership of oil and natural gas interests, while providing, in Japan, a stable supply of gas using
infrastructure such as pipelines and LNG terminals and supplying electricity from natural gas-fired power generation andrenewable energy sources. As such, JAPEX conducts a business with a highly public nature, as well as taking on a crucially
important responsibility in terms of maintaining and ensuring stable supply and safe operation as an enterprise involved in the
supply of energy, which is compared to the bloodstream of industrial activity and civic life. Moreover, to contribute to therealization of a carbon-neutral society, JAPEX is working toward the early commercialization of CCS (Carbon dioxide captureand storage) and CCUS (Carbon dioxide capture, utilization, and storage), mainly utilizing E&P technologies.
This business model is backed with JAPEX’s 1) advanced exploration technology for oil and natural gas, 2) comprehensive
technological capabilities such as oil/gas field development technology and operation know how both in and out of Japan, 3)
construction of a strong infrastructure such as natural gas transport pipelines and LNG terminals in Japan, and 4) trust
relationships with our stakeholders including customer, stockholder and community, based on the buildup of a stable, long-term
supply record due to the aforementioned network.
It is not uncommon for it to take more than 10 years to reach the production stage from exploration of a new oil or gas field in the
E&P business. In addition, in order to contribute to the realization of a carbon-neutral society, it is required to develop businesswith a long-term perspective and contribute to society through consideration for the protection of the global environment. Also, inthe view of today’s international energy situation, in which the global competition with regard to the securement of energy
resources is intensifying, efforts for improvement of corporate technology and know-how, securing human resources, and thefurther enrichment of trust relationships with each stakeholder are essential for the continuing growth of the business andenhancement of our corporate value. This, we believe, is still what brings the future maintenance and improvement of ourcorporate value and thus of the common interest of our stockholders.
2. Undertakings for the improvement of corporate value
In view of the irreversible changes in energy demand structure due to global progress toward decarbonization, in May 2021 we- 58 -

formulated and announced “JAPEX 2050,” which outlines our responsibilities toward the realization of a carbon-neutral society
and our direction for future business development.
In addition, in March 2022, we formulated and announced the “JAPEX Management Plan 2022–2030,” which sets forth a basic
policy of improving profitability and building a business foundation for 2030 and beyond.
A summary of “JAPEX 2050” and “JAPEX Management Plan 2022-2030” is as described in “Item 2. Overview of Business, 1.
Management Policy, Business Environment, and Issues to be Addressed, (2) Medium- to long-term management strategies andissues to be addressed.”
By steadily implementing “JAPEX 2050” and “JAPEX Management Plan 2022–2030,” we will continue to contribute to therealization of a carbon-neutral society in 2050 and further increase our growth and corporate value as a comprehensive energy
company.
3. Fortification of Corporate Governance
JAPEX plans to implement the above measures and intends to acquire and improve our corporate value and consequently thecommon interest of our shareholders. Furthermore, we believe that our path to sustainable growth over the long term lies in
efficient and transparent management and building relationships of trust by fulfilling our accountability to shareholders and otherstakeholders. To this end, we are striving to enhance corporate governance.
First of all, Directors or Executive Officers, who are appointed and assigned duties by the Representative Directors and Board of
Directors, serve as JAPEX’s operating officers. The Board of Directors and Audit & Supervisory Board Members (along with the
Audit & Supervisory Board that is comprised of all Audit & Supervisory Board Members) assume the role of supervising theexecution of their duties.
In addition, in order to strengthen the supervisory function of the Board of Directors, JAPEX has appointed five Outside
Directors who are highly independent and have deep insight. The Outside Directors contribute to vigorous discussion at meetingsof the Board of Directors by actively providing comments on proposals and deliberations. In addition, with a view to providing
sufficient information to Outside Directors, thereby helping them perform their role appropriately, JAPEX has arrangements inplace including liaison meetings for Outside Directors and Outside Audit & Supervisory Board Members for providing
preliminary briefing to Outside Directors and Outside Audit & Supervisory Board Members on proposals for the Board of
Directors, as well as for exchanging information and opinions among them.
All Audit & Supervisory Board Members attend the Board of Directors’ Meeting and the full-time Audit & Supervisory Board
Members also attend the other important meetings as well as exchange opinions with Directors who execute business operations
or Executive Officers as appropriate, thus serving in the supervisory function. Furthermore, as an internal audit, the Auditing
Department evaluates the systems and execution of various management activities of JAPEX from the viewpoint of legality andrationality, and provides suggestions and advice for improvement and rationalization to the subject departments as necessary.
Furthermore, the Nomination and Compensation Advisory Committee has been established under the Board of Directors, with aview toward strengthening the supervisory function of the Board of Directors, by further ensuring the transparency andobjectivity of the procedures for making decisions concerning the nomination and compensation of Directors.
On the other hand, concerning the internal control, the Risk Management Committee, as the main actor, is continuing its
inspection and development of the framework to ensure due business operation.
Furthermore, in addition to such corporate governance in management mechanism, we anticipate to attain the optimal businessexecution appropriately, through improved transparency of management brought by IR activities such as results briefings andenrichment of the website.
(3) Undertakings based on the basic policy to prevent the controlling of decision of policies of our finances and business byinappropriate persons (the “Plan”)
1. Purpose of the Plan
The Plan has been adopted according to the Basic Policy described above (1) for the purpose of ensuring and improving ourcorporate value and the common interests of our shareholders.
The Board of Directors, as set forth in the Basic Policy, considers a person who performs the large-scale acquisition of JAPEX
share certificates, etc., without contributing to our corporate value and/or the common interests of our shareholders inappropriate- 59 -

for making financial and business policy decisions regarding JAPEX. The Plan aims to prevent the control of our financial andbusiness policies by such inappropriate persons and deter large-scale acquisition that is detrimental to our corporate value and/or
the common interests of our shareholders. At the same time, the Plan shall allow JAPEX’s Board of Directors to ensure thenecessary information and time required to propose an alternative plan to our shareholders or for our shareholders to sufficiently
judge whether such a large-scale acquisition of JAPEX share certificates, etc., is acceptable and/or allow negotiation and othermeasures to be taken on behalf of our shareholders.
2. Overview of the Plan
The Plan determines the necessary procedure for achieving the aforementioned purpose, such as demanding the prior provision of
information from the acquirer, upon the emergence of a person who intends to acquire 20% or more of JAPEX share certificates,etc.
In case the decision of not implementing the Plan has been made by the Board of Directors based on the procedures of the Plan,
the acquirer shall be authorized to make a large-scale acquisition of JAPEX share certificates, etc., only after such a board
decision.
In case the acquirer does not comply with the procedure set forth in the Plan or the intended large-scale acquisition of JAPEX
share certificates, etc., has a risk of impairing our corporate value and/or the common interest of our shareholders and if thepredetermined requirements for the implementation of the Plan are satisfied, JAPEX shall allot share options without contribution
regarding those with exercise conditions in which the exercise of rights by the acquirer is, in principle, impermissible or withacquisition clauses where JAPEX may, in principle, acquire share options from persons other than the acquirer in exchange for
JAPEX shares and shall implement any other reasonable measures that could be taken under the laws and regulations and
JAPEX’s Articles of Incorporation.
In the event that the allotment of share options without contribution is executed according to the Plan, and associated by its
execution or acquisition by JAPEX, when JAPEX shares are issued to all shareholders except for the acquirer, the percentage ofvoting rights the acquirer holds may be diluted up to a maximum of approximately 50%.
With regard to the decision whether to implement or not implement the allotment of share options without contribution, or toacquire, according to the Plan, in order to eliminate the arbitrary decision of the Board of Directors, it shall undergo the objective
decision of the Independent Committee constituted only of Outside Director etc., who are independent from JAPEX’s Board of
Directors pursuant to the Independent Committee Provision.
Following persons are members of the Independent Committee.
ITO Tetsuo, Outside Director, JAPEXYAMASHITA Yukari, Outside Director, JAPEXKAWAKITA Chikara, Outside Audit & Supervisory Board Member, JAPEX
Moreover, in the event that the allotment of share options without contribution is implemented according to the Plan, the Board of
Directors shall, in principle, convoke a general meeting of the shareholders to confirm the decision of the shareholders
concerning said implementation of the allotment of share options without contribution.
We aim to ensure transparency of the process of these procedures through the timely disclosure of appropriate information to ourshareholders.
The effective period of the Plan shall be until the close of the Ordinary General Meeting of the Shareholders regarding the latest
fiscal year ending within three years after the close of the Ordinary General Meeting of the Shareholders, which is the same as thedelegation period of the authority to decide the matters concerning the allotment of the Share Options without contribution in thePlan to be in accordance with the resolution of the 53rd Ordinary General Meeting of the Shareholders held on June 27, 2023.
However, even before the expiration of the effective period, if a resolution to abolish the Plan is made by the Board of Directors,
the Plan shall be abolished at that point in time.
Details of the Plan is available on our website. Please refer to our news release “Renewal of the Measures to Prevent Large-scale
Acquisition of Our Company Shares (Takeover Defense Measures)” issued on May 12, 2023.
(https://www.japex.co.jp/en/news/uploads/pdf/JAPEX20230512_TDM_Update_e.pdf)(4) Decision and its reason of the Board of Directors concerning the Plan

- 60 -

1. The Plan must be in accordance with the Basic Policy
The Plan is a framework in accord with the Basic Policy that ensures our corporate value and consequently the common interest of ourshareholders, by enabling the decision-making of shareholders concerning the acceptance of the Acquisition, or ensuring theinformation and time necessary for the proposal of an alternative plan by the Board of Directors, and/or enabling negotiation or othercommunication with the Acquirer on behalf of the shareholders, in the event of Acquisition of JAPEX share certificates, etc.
2. The Plan must not be such that is detrimental to the common interest of our shareholders and does not serve the purpose ofretaining the position of our corporate officers.
JAPEX considers the Plan to be not detrimental to the common interest of our shareholders and that it does not serve the purpose ofretaining the position of our corporate officers for the following reasons:1) That the Plan satisfies the guiding requirements of the takeover defense measure:
The Plan satisfies the three principles (1) the principle of protecting and enhancing corporate value and shareholders’common interests; (2) the principle of prior disclosure and shareholders’ will; and (3) the principle of ensuring the necessity
and reasonableness of defensive measures, set forth in the Guidelines Regarding Takeover Defense for the Purposes ofProtection and Enhancement of Corporate Value and the Shareholders’ Common Interests announced by the Ministry of
Economy, Trade and Industry and the Ministry of Justice on May 27, 2005.
2) That the Plan respects the decision of the shareholders:
The introduction of the Plan was tabled and discussed at the 38th Ordinary General Meeting of Shareholders held on June25, 2008 to confirm the intention of shareholders and was approved at the meeting. So were the updates of the Plan at thefollowing Ordinary General Meetings of Shareholders: the 41st meeting held on June 24, 2011; the 44th meeting held on
June 25, 2014; the 47th meeting held on June 28, 2017; the 50th meeting held on June 26, 2020; and the 53rd meeting heldon June 27, 2023.
And the Board of Directors made it clear that JAPEX holds a General Meeting of Shareholders to hear shareholders’decision regarding the implementation of the Plan for certain cases depicted in the Plan.
In addition, the Plan contains a sunset provision that stipulates an effective period of approximately three years. Alongside,even before the expiration of the effective period, if a resolution abolishing the Plan is made by the Board of Directors, thePlan shall be abolished at that point of time. In that context, the intention of our shareholders will be reflected on theprevalence of the Plan.
3) Respect for the decision of the Outsider Directors and Outside Audit & Supervisory Board Members and information
disclosure
The practical decisions on the operations of the Plan are executed by the Independent Committee which only consists of
Outside Directors and Outside Audit & Supervisory Board Members who are independent.
Furthermore, the overview of the decision is to be disclosed to our shareholders, ensuring the framework for a transparent
operation of the Plan to serve the corporate value and the common interest of our shareholders.
4) Establishment of reasonable objective requirements
The Plan shall not be implemented if it does not meet the reasonable objective requirements, ensuring the framework toprevent the arbitrary implementation by the Board of Directors.
5) Hearing of opinions from third party experts
When an acquirer emerges, the Independent Committee may receive advice from financial advisors, certified public
accountants, lawyers, certified tax accountants, consultants, and other experts at the expense of JAPEX. This creates amechanism for securing fairness and objectivity of the decisions given by the Independent Committee to a stronger degree.
6) That the takeover defense measure is not a dead-hand or slow-hand type measure
A large-scale purchaser of JAPEX share certificates, etc. can appoint Directors of their own designation in a general meetingof the shareholders and abolish this Plan through the Board of Directors constituted of such Directors.
Therefore, the Plan is not a dead-hand type takeover defense measure (a takeover defense measure of which implementation
cannot be deterred even with the replacement of over half of the constituting members of the Board of Directors).

- 61 -

Furthermore, the assumption of Directors at JAPEX does not employ the staggered system, which does not make the Plan aslow-hand type takeover defense measure (a takeover measure of which implementation takes time to deter due to theimpossibility of an all-together replacement of the constituting members of the Board of Directors).

2) Outside Officers(The number of Officers)
The number of JAPEX’s Outside Directors is five and the number of its Outside Audit & Supervisory Board Members is two.
(Personal, capital, material business relationships or any other conflicts of interest with JAPEX)JAPEX has entered into business transactions with Nishimura & Asahi, where Outside Director ITO Tetsuo serves Of
Counsel. However, considering the scale and the nature of the transactions, the decision-making of JAPEX will not besignificantly affected. In addition, no relationships exist that may raise conflict of interest with our other general shareholders.
JAPEX has entered into business transactions with The Institute of Energy Economics, Japan, where Outside Director
YAMASHITA Yukari serves as a Managing Director. However, considering the scale and the nature of the transactions, thedecision-making of JAPEX will not be significantly affected. In addition, no relationships exist that may raise conflict ofinterest with our other general shareholders.
Outside Audit & Supervisory Board Member MOTOYAMA Hiroshi served as executive at Mizuho Bank, Ltd., one of the
major shareholders of JAPEX (a shareholding ratio of 1.33% as of March 31, 2023), but about 12 years have passed since heretired. Considering the shareholding ratio as of March 31, 2023, the decision-making of JAPEX will not be significantly
affected. In addition, no relationships exist that may raise conflict of interest with our other general shareholders.
All the Outside Directors and Outside Audit & Supervisory Board Members, including the ones above, do not have conflictsof interest with JAPEX.
(Functions and roles to be played in corporate governance and criteria or policies concerning independence)
We believe that, by appointing Outside Directors, the supervisory functions of the Board of Directors will be strengthened.
We also believe that, by letting the Outside Directors and Outside Audit & Supervisory Board Members actively commenton and give advice on the meeting agenda, deliberations and other matters from an independent standpoint from management,
we can invigorate discussion at the meeting of the Board of Directors.
JAPEX nominates Outside Directors and Outside Audit & Supervisory Board Members who have experience as a corporate
manager at a private firm, and persons with legal expertise, among others, because such persons can provide supervision andwide-ranging proposals to our management based on their abundant experience and deep insight. In addition to meeting theindependence criteria stipulated by the Tokyo Stock Exchange, JAPEX regards that a person is independent if the person does
not meet any of the following conditions:i)

An executive of a company that provides products or services to JAPEX and for which the amount paid by JAPEX
exceeds 2% of the consolidated net sales of the company in any of the last three fiscal yearsii)

An executive of a company in which JAPEX’s borrowings account for more than 2% of the consolidated total assets ofiii)

An executive of a company to which JAPEX provides products or services and whose payments to JAPEX exceed 2%

JAPEX in any of the last three fiscal yearsof the consolidated net sales of JAPEX in any of the last three fiscal years
iv)

A person who has received compensation exceeding ¥10 million per year from JAPEX as a consultant, accounting
expert, or legal expert in any of the last three years in addition to officer compensation (in the case of an organizationsuch as a corporation or association, a person who belongs to such organization)v)

A relative within the second degree of kinship of a person who falls under any of (1) through (4) below:(1) A person listed in i) to iv) above(2) An executive of a subsidiary of JAPEX(3) A director who is not an executive of a subsidiary of JAPEX (limited to cases where an Outside Audit & Supervisory
Board Member is designated as an independent officer)(4) A person who fell into (2) or (3) above, or was an executive of JAPEX (including a director who is not an executive
if an Outside Audit & Supervisory Board Member is designated as an independent officer) in the past three years- 69 -

(Our stance on the appointment)
We believe the current appointment of Outside Directors and Outside Audit & Supervisory Board Members is reasonablefrom a standpoint of governance such as the number and structure of Directors and Audit & Supervisory Board Members.

(4) Compensation for Directors and other Officers
1) Policy for determining the compensation amount for Directors and other officers or the calculation method thereof(a) Compensation for Directors
Compensation for Directors is determined based on the policy for determining the compensation of directors set by the Boardof Directors after deliberation by the Nomination and Compensation Committee. In determining the details of compensationfor each Director for the fiscal year under review, the Nomination and Compensation Committee deliberated on the draft
based on the determination policy. The Board of Directors therefore judged that the details were in line with the determination
policy, with the respect for the Committee’s deliberation results. The policy for determining the compensation of directors isoutlined below.

Basic policy

・Regarding the compensation of directors, the compensation structure can function as anincentive to sustainably enhance corporate value. When deciding the compensation ofindividual directors, our basic policy is to set an appropriate level in consideration of theroles aligned with their position.
・Specifically, the compensation of directors (excluding outside directors) comprises basecompensation and performance-linked compensation (bonuses and share-based
compensation). Compensation for outside directors is only base compensation, considering
their duty of supervising management.

Policy for determiningbase compensation(monetarycompensation)・Base compensation of JAPEX’s directors is fixed monthly monetary compensation and isdecided in comprehensive consideration of their position, balance with market standard
and employees’ salaries, number of years of service, and more.

Policy for determining
performance-linked, or
non-monetarycompensation

・Of performance-linked compensation, bonuses are paid at certain times every year basedon consolidated net income as an indicator measuring their contribution to results for thecorresponding fiscal year. Specifics are decided in comprehensive consideration of theirposition, dividends, the level of employee bonuses, their contribution of directors tocorporate management in each fiscal year, past results, payment record, and more.
Individual Director’s contribution to JAPEX’s management is measured based on theachievement of previously set annual goals and business plans (including GHG reduction
target), human resource management, leadership, and execution ability, in addition to theaforementioned contribution to business performance.
・Of performance-linked compensation, share-based compensation is based on the Rules on
Provision of Shares to Officers approved by the Board of Directors within the limit
approved at the General Meeting of Shareholders. JAPEX shares equivalent to the numberof points provided in line with their positions and performance (using a total return ratio asa general rule as an indicator of performance evaluation based on JAPEX’s recognition that
returning profits to shareholders is an important management issue) and a monetaryamount equivalent to the market price of said shares is provided as a general rule todirectors upon retirement.
Note: The policy for provision of share-based compensation before FY2022 was to use
annual dividend amounts as a general rule as an indicator of performance evaluation.

Policy concerning theratio of compensation

・We aim for the ratio of performance-linked compensation (bonuses and share-based
compensation) to total compensation to be around 30% at standard amounts. To ensure thecompensation system can better function as an incentive to sustainably enhance corporate
value, we will consider revising the ratio as appropriate.

- 75 -

Matters on
determination ofcompensation

・Regarding individual compensation, the representative director and president is entrustedwith the specific details based on a resolution by the Board of Directors. That authority
enables the allocation of bonuses based on each director’s base compensation and the
directors’ contribution to corporate management. It also enables the setting of the specifictiming of the payment.
・Calculation methods for base compensation and bonuses are deliberated in advance at theNomination and Compensation Committee. The representative director and president must
decide the method with respect to the results of the deliberations.
・The provision of points in share-based compensation is reported in advance of theNomination and Compensation Committee.

(b) Compensation of Audit & Supervisory Board Member
Compensation for Audit & Supervisory Board Members is determined after consulting with Audit & Supervisory Board
Members, and within the limit approved at a General Meeting of Shareholders.
(c) Details of non-monetary performance-linked compensation
In accordance with the resolution of the 50th Ordinary General Meeting of Shareholders held on June 26, 2020, JAPEX has
introduced a share-based compensation plan (Board Benefit Trust) for Directors (excluding Outside Directors) and Executive
Officers who do not concurrently serve as Directors, as mentioned in (h) below.
(d) Policy on determining payment ratios of performance-linked and non-performance-linked compensation
The policy is the same as (a) above.
(e) Indicators used for performance-linked compensation, reasons why we use them and how we decide on the amount of theperformance-linked compensation
Performance-linked compensation is composed of bonus and share-based compensation. For bonuses, consolidated profit isused as an indicator to measure contribution to business performance for the corresponding fiscal year. For share-based
compensation, a total shareholder return ratio is used as an indicator of performance evaluation as JAPEX recognizes that
returning profits to shareholders is an important management issue. By setting these indicators, we aim to raise awarenessamong Directors, etc. of improving business performance for the corresponding fiscal year, as well as to motivate them tocontribute to the improvement of the business performance and corporate value of JAPEX over the medium and long term
and the improvement of profit distribution to shareholders. The amount of performance-linked compensation is decided inaccordance with the policy for determining compensation for Directors described in (a) above.
(f) Target and actual figures of indicators used for performance-linked compensation
Of performance-linked compensation, the specific target for the indicator used for bonuses (consolidated profit) has not beenset, as our business performance is often affected by external factors such as fluctuations of crude oil and natural gas prices
as well as foreign exchange rates, and therefore it is difficult to set right figure that works as an incentive. For the fiscal year
under review, JAPEX posted consolidated profit of ¥67,394 million. The target for the indicator for the fiscal year underreview used for share-based compensation was annual dividend amount. The target for the fiscal year under review was ¥50
per share as stated in (h) below, and the actual amount paid for the fiscal year under review was ¥370 per share.
(g) Policy on determination of compensation amount by position or the calculation method thereof
As described in the policy for determining compensation for Directors in (a) above, our basic policy for deciding thecompensation amount for Directors is to set it at an appropriate level in consideration of their roles and others according totheir position.
(h) Summary of resolutions related to compensation at General Meetings of Shareholdersi) The following was resolved on monetary compensation for Directors at the General Meeting of Shareholders. The
number of eligible Directors as of the filing date is 11, including five Outside Directors.

JAPEX classifies shares of companies we have determined to be necessary to promote smooth business execution and tomaintain good business relationships for the purpose of achieving sustainable growth and enhancing medium- to long-term
corporate value as “investment shares held for purposes other than pure investment (strategic shareholdings)” separately frominvestment shares held for pure investment purposes.

4. Disclosure of accounting policies(1) Accounting policy for measuring significant assets
1) Securities
Held-to-maturity debt securities
Stated at amortized cost.
Available-for-sale securities
Available-for-sale securities other than shares, etc. without market priceStated at fair value based primarily on the market price at the fiscal year-end. Unrealized gains and losses
are recognized directly in net assets and the cost of securities sold is determined using the moving-averagemethod.
Shares, etc. without market priceStated at cost using the moving-average method.
Investments in limited investment partnerships and silent partnerships are recorded by adding or
subtracting the amount of equity interest in the net assets of the partnerships to/from “investment
securities.”2) Derivatives
Stated at fair value.
3) Inventories
Stated at cost (a method in which carrying amount is written down based on any decline in profitability).
Merchandise and finished goods
Stated mainly by the first-in, first-out method.
Raw materials and supplies
Stated mainly by the moving-average method.
(2) Accounting policy for depreciation/amortization of significant assets
1) Property, plant and equipment (excluding leased assets)
Buildings (excluding attached facilities) acquired on or after April 1, 1998, facilities attached to buildings andstructures of certain domestic consolidated subsidiaries acquired on or after April 1, 2016, Sendai gas pipelines,
Shiroishi-Koriyama gas pipelines, Soma-Iwanuma gas pipelines, assets of the Hokkaido District Office andSoma District Office of JAPEX, and property, plant and equipment items held by three domestic consolidated
subsidiaries are depreciated by the straight-line method.
Property, plant and equipment items held by a foreign consolidated subsidiary are depreciated by the unit ofproduction method.
Other property, plant and equipment items are depreciated by the declining-balance method.
The principal useful lives are as follows:
Buildings and structures: 2 to 60 years
Wells: 3 years
Machinery, equipment and vehicles: 2 to 22 years
2) Intangible assets (excluding leased assets)
Amortized by the straight-line method.
Capitalized computer software costs are amortized by the straight-line method over a period of 5 years, which isthe period available for internal use.
Intangible assets of one foreign consolidated subsidiary are mainly amortized by the unit of production method.
3) Leased assets
Finance leases which do not transfer ownership of the leased assets to the lessee
Leased assets are depreciated by the straight-line method over the lease terms with no residual value.

- 93 -

(3) Accounting policies for significant provisions
1) Allowance for doubtful accounts
To provide for potential credit losses on receivables, the allowance for doubtful accounts is stated at the amountdetermined based on the historical experience of bad debt with respect to ordinary receivables, plus an estimateof uncollectible amounts determined by reference to specific doubtful receivables from customers which areexperiencing financial difficulties.
2) Allowance for overseas investment loss
The allowance for overseas investment loss is stated at the amount determined based on the investees’ financial
position and certain other factors for possible losses arising from investments in the exploration anddevelopment of overseas natural resources.
3) Provision for loss on disaster
The provision for loss on disaster is stated at the estimated amount of payment for restoration expenses
accompanying disasters.
(4) Accounting treatment of retirement benefits
1) Method of attributing expected benefit to periods
The retirement benefit obligations for employees are attributed to each period by the benefit formula method
over the estimated years of service of the eligible employees.
2) Accounting treatment of actuarial gains and losses and prior service costs
Prior service costs are amortized as incurred by the straight-line method over a certain period (10 years), whichis shorter than the average remaining years of service of the employees.
Actuarial gains and losses are amortized in the following year in which the gains or losses are recognized by thestraight-line method over a certain period (10 years), which is shorter than the average remaining years ofservice of the employees.
3) Application of simplified method for smaller enterprises
Certain consolidated subsidiaries apply the simplified method for calculating retirement benefit expenses andliabilities based on the assumption that the benefits payable, which are calculated as if all eligible employees
voluntarily terminated their employment at fiscal year-end, approximates the retirement benefit obligation at
year’s end.
(5) Accounting policies for significant revenues and expenses
With regard to revenues from contracts with clients of JAPEX and its consolidated subsidiaries, the main
performance obligations in key businesses and the timing at which these obligations are typically satisfied (i.e.,
when revenues are typically recognized) are as follows.
JAPEX and its consolidated subsidiaries conduct the “E&P Business,” the “Infrastructure/Utility Business,” and“Other businesses” in the four reportable segments provided in the segment information: “Japan,” “North
America,” “Europe” and “Middle East.”
1) E&P BusinessIn the E&P Business, exploration, development, production, production services, and sales of crude oil and natural
gas are conducted at business locations in Japan and overseas. It is judged that in these sales, legal ownership andphysical possession of assets, as well as significant risks and economic rewards associated with ownership ofassets, are transferred, and the right to receive consideration for delivered products is obtained, at the time theproducts are delivered to clients. Thus, revenue is recognized at that time. As for production services, when control
over goods or services is transferred to clients over a certain period of time, revenue is recognized according toprogress in the satisfaction of performance obligations. For measurement of progress, the output approach basedon production volume is used.
2) Infrastructure/Utility BusinessIn the Infrastructure/Utility Business, sales of gases (natural gas and LNG) and electricity are conducted atbusiness locations in Japan. It is judged that in these sales, legal ownership and physical possession of assets, aswell as significant risks and economic rewards associated with ownership of assets, are transferred, and the right toreceive consideration for delivered products is obtained, at the time the products are delivered to clients. Thus,
revenue is recognized at that time.

- 94 -

3) Other businesses
In the Other businesses, contract services (drilling and geological surveys, etc.) and sales of oil products, etc. areconducted at business locations in Japan. As for contract services, when control over goods or services istransferred to clients over a certain period of time, revenue is recognized according to progress in the satisfactionof performance obligations. For measurement of progress, the input approach based on incurred costs is used. It is
judged that in sales of oil products, etc., legal ownership and physical possession of assets, as well as significant
risks and economic rewards associated with ownership of assets, are transferred, and the right to receive
consideration for delivered products is obtained, at the time the products are delivered to clients. Thus, revenue isrecognized at that time.
For all businesses, in identification of performance obligations, it is examined whether the JAPEX Group acts as aprincipal or an agent. If the nature of its promise is a performance obligation to provide the specified goods orservices itself, as a principal it presents revenue at the gross amount of consideration in its consolidated statementof income. If the nature is a performance obligation to make arrangements so that these goods or services areprovided by other parties, as an agent it presents revenue at the amount of commissions or fees, or the net amountof consideration, in its consolidated statement of income.
Revenue is recognized based on the transaction price under contracts with clients. If a contract contains multiple
performance obligations, the transaction price is allocated to each performance obligation at a ratio of standalone
selling price. Since consideration for transactions is usually paid within one year after the satisfaction of
performance obligations, such consideration does not include any significant financing component.
(6) Accounting policy for translating significant foreign currency assets and liabilities into yen
Monetary receivables and payables denominated in foreign currencies are translated into yen at the spot exchange
rate on the consolidated balance sheet date, and the resulting translation adjustments are presented as foreignexchange gains or losses. Meanwhile, assets, liabilities, revenues and expenses of foreign consolidated
subsidiaries, etc. are translated into yen at the spot exchange rate on their respective balance sheet dates, and theresulting translation adjustments are included in foreign currency translation adjustment under net assets.
(7) Significant hedge accounting
1) Hedge accounting method
Deferral hedge accounting is adopted for hedge transactions. Foreign exchange forward contracts are accounted
for by the allocation method if the foreign exchange forward contracts meet certain criteria to adopt the method.
2) Hedging instruments and hedged items
Hedging instruments: Foreign exchange forward contracts and crude oil swaps
Hedged items: Accounts payable – trade, accounts payable – other and proceeds from sale of crude oil
3) Hedging policy
To avoid future foreign currency fluctuation risk associated with foreign currency transactions, etc. and oil pricefluctuation risk, the Group enters into hedge transactions only in connection with the relevant assets, liabilities andforecast transactions.
4) Method of assessing the effectiveness of hedges
The Group assesses whether the critical terms of the hedging instruments and hedged items are closely aligned,
and the hedge transactions are effective in offsetting the price fluctuation, etc. at the inception of the hedge and on
an ongoing basis.
Forward exchange contracts accounted for by the allocation method are not subject to the assessment of hedge
effectiveness.
(8) Scope of cash and cash equivalents in the consolidated statement of cash flows
Cash and cash equivalents in the consolidated statement of cash flows consist of cash on hand, readily available
deposits and highly liquid short-term investments with maturities of three months or less when purchased that are
exposed to an insignificant risk of changes in value.

- 95 -

(9) Other material matters for preparation of consolidated financial statements
Accounting treatment of recoverable accounts
Investments made under a development and production service contract are included in recoverable accounts.
These investments are recovered through sales to customers of a portion of the crude oil production received basedon the contract.
In addition, an amount corresponding to the recovered investments at the time of sale is recorded as cost of sales.
(Significant accounting estimates)
Recoverability of deferred tax assets(1) Amounts recorded in the consolidated financial statements for the fiscal year ended March 31, 2023
(Millions of yen)
As of March 31, 2022
Deferred tax assets

As of March 31, 2023
20,83722,162

Note: The amount is before offset with deferred tax liabilities.
(2) Information about significant accounting estimates on identified items
1) Calculation method
JAPEX reviews the recoverability of deferred tax assets in accordance with the “Implementation Guidance on
Recoverability of Deferred Tax Assets.”
As of March 31, 2023, deductible temporary differences which are deemed recoverable and net tax loss carriedforward are recognized as deferred tax assets as a result of the scheduling of temporary differences based on theestimated amount of taxable income before adding or subtracting temporary differences for the following fiscal
year.
In addition, consolidated subsidiaries recognize deferred tax assets in accordance with respective accounting
standards they apply.
2) Major assumptions used for significant accounting estimates
The recoverability of deferred tax assets is largely dependent on estimates of future taxable income. JAPEX and its
consolidated subsidiaries estimate the timing and amount of future taxable income in accordance with the tax lawsof the respective countries. The assumptions underlying these estimates, such as the sales price of each product,sales volume and foreign exchange rates, are incorporated into the business plans approved by management.
Although the COVID-19 pandemic, which is one of the factors affecting the above assumptions, continues to havea certain impact on economic activities in Japan and overseas, we believe that this situation is improving.
Also, while the current situation in Russia and Ukraine has destabilized crude oil and natural gas prices globally,
we believe that various structural changes brought about by the progress on global decarbonization could be a risk
factor for future demand for fossil fuels. In light of the changes in the business environment surrounding ourcompany and the trend of rising global carbon prices, our projection for the medium- to long-term oil price is set
at US$50 per barrel.
Taking into consideration the impact of such business conditions on the future business environment, JAPEX has
calculated the amount of deferred tax assets to the extent that it is probable that taxable income will be available
against which the deductible temporary differences and net tax loss carried forward can be utilized.
3) Effects on the consolidated financial statements for the year ending March 31, 2024
Any changes in the above assumptions may affect taxable income and increase or decrease the amount of deferred
tax assets recorded for JAPEX and its consolidated subsidiaries.
The amount of deferred tax assets may also increase or decrease as a result of reexamining the reasonably estimableperiod in the future due to changes in the above assumptions in order to examine the recoverability using taxable
income based on future profitability and tax planning estimates for deductible temporary differences and net tax
loss carried forward for consolidated subsidiaries.

Note: Explanation of valuation techniques and inputs used in the fair value measurement
Investment securities
Listed shares are valued using quoted prices. As listed shares are traded in active markets, their fair value is classified as Level
1.
The fair value of shares other than listed shares is classified as Level 2 because they are traded infrequently in the public market
and not considered to have quoted prices in active markets.
The fair value of held-to-maturity debt securities is measured using the discounted cash flow method based on future cash flows
from debt securities and appropriate benchmarks such as market rate of return. As unobservable inputs have a significant effecton the fair value measurement, it is classified as Level 3.
Long-term loans receivable
The fair value of long-term loans receivable is measured using the discounted cash flow method based on future cash flows andappropriate benchmarks such as market rate of return, and is classified as Level 2.
Derivative transactions
The fair value of derivative transactions is measured based on quotes, etc. provided by financial institutions, and is classified as
Level 2.
Long-term borrowings
The fair value is measured using the discounted cash flow method based on the sum of principal and interest, remaining
maturities and an interest rate reflecting credit risk, and is classified as Level 2.

During the year ended March 31, 2022, the Group recorded no impairment loss on securities.
During the year ended March 31, 2023, the Group recorded impairment losses of ¥10 million on available-for-salesecurities without market value.
If the market value of the securities other than shares without market value declines by 50% or more from its
acquisition cost as of the end of the fiscal year, in principle, the Group recognizes the difference between the market
value and the acquisition cost as impairment losses. If the decline ranges between about 30% and 50%, the Group
recognizes impairment losses for the necessary amount considering its recoverability.
If the real value of shares without market value declines by 50% or more from its acquisition cost, the Group- 113 -

(Asset retirement obligations)
1. Asset retirement obligations recognized in the consolidated balance sheets
Asset retirement obligations recognized by the Group are determined based on the estimated costs ofdecommissioning oil and natural gas wells and production facilities in accordance with laws, land lease contracts,
etc. for wells and production facilities in Japan and overseas, and the appropriate discount rates.
The Group estimates the periods in which the obligations are paid out to be approximately 2 to 35 years fromacquisition of assets. This estimate is reasonably made based on the plans for decommissioning wells and facilitiesor the estimated producing lives of fields if no such plan exists. Discount rates applied are (0.186)% to 2.287% for
domestic obligations and 2.25% to 4.84% for overseas.
Although the future costs to be incurred upon decommissioning and timing when the obligations are incurred are
based on the Group’s best estimate, uncertainty exists regarding both the amount and timing of incurring thesecosts.
Changes in the balance of asset retirement obligations are as follows:(Millions of yen)

Limited in September 2021.
2. Asset retirement obligations other than those recognized in the consolidated balance sheets
The Group has obligations to restore sites to their original condition in accordance with laws, land lease contracts,
etc. regarding oil and natural gas production facilities. However, maintaining and ensuring a stable supply of natural
gas in the Infrastructure/Utility Business, which is the Group’s primary business operation, is of high public
interest; therefore, even after completion of production activities, the Group plans to continue to use some of theassets held for the purpose of producing and selling oil and gas on a permanent basis in order to fulfill the
responsibilities as a supplier for users of natural gas by holistically integrating these assets. Thus, the Group does
not recognize the relevant asset retirement obligations since it is impossible at this point to estimate asset retirement
obligations on a reasonable basis as of March 31, 2023.

included in contract liabilities as of the beginning of the period. The revenue the Group recognized related to performanceobligations that were satisfied, or partially satisfied, in previous periods was immaterial.
(2) Transaction price allocated to the remaining performance obligations
The following table summarizes the aggregate transaction price allocated to the remaining performance obligations inconstruction contracts, etc. and the period over which revenue is expected to be recognized.

with respect to ordinary receivables, plus an estimate of

(3) Provision for retirement benefits

To provide for the payment of retirement benefits toemployees, etc., the provision for retirement benefits isstated at the estimated amount of retirement benefit
obligations and plan assets at the end of the fiscal year underreview.
In calculating retirement benefit obligations, JAPEX uses thebenefit formula basis to attribute expected retirement

Prior service costs are amortized as incurred by the straightline method over a certain period (10 years), which is shorter
than the average remaining years of service of theemployees.
Actuarial gains and losses are amortized in the following

4. Accounting policies for revenues and expenses
With regard to revenues from contracts with clients of JAPEX, the main performance obligations in key businesses
and the timing at which these obligations are typically satisfied (i.e., when revenues are typically recognized) are as
follows.
JAPEX conducts the “E&P Business,” the “Infrastructure/Utility Business,” and “Other businesses” at businesslocations in Japan.
(1) E&P BusinessIn the E&P Business, exploration, development, production, and sales of crude oil and natural gas are conductedat business locations in Japan. It is judged that in these sales, legal ownership and physical possession of assets,
as well as significant risks and economic rewards associated with ownership of assets, are transferred, and theright to receive consideration for delivered products is obtained, at the time the products are delivered to clients.
Thus, revenue is recognized at that time.

- 143 -

(2) Infrastructure/Utility BusinessIn the Infrastructure/Utility Business, sales of gases (natural gas and LNG) and electricity are conducted atbusiness locations in Japan. It is judged that in these sales, legal ownership and physical possession of assets, aswell as significant risks and economic rewards associated with ownership of assets, are transferred, and the rightto receive consideration for delivered products is obtained, at the time the products are delivered to clients. Thus,
revenue is recognized at that time.
(3) Other businesses
In the Other businesses, contract services (drilling, etc.) and sales of oil products, etc. are conducted at businesslocations in Japan. As for contract services, when control over goods or services is transferred to clients over acertain period of time, revenue is recognized according to progress in the satisfaction of performance obligations.
For measurement of progress, the input approach based on incurred costs is used. It is judged that in sales of oil
products, etc., legal ownership and physical possession of assets, as well as significant risks and economic
rewards associated with ownership of assets, are transferred, and the right to receive consideration for delivered
products is obtained, at the time the products are delivered to clients. Thus, revenue is recognized at that time.
For all businesses, in identification of performance obligations, it is examined whether JAPEX acts as a principal oran agent. If the nature of its promise is a performance obligation to provide the specified goods or services itself, as aprincipal it presents revenue at the gross amount of consideration in its statement of income. If the nature is a
performance obligation to make arrangements so that these goods or services are provided by other parties, as anagent it presents revenue at the amount of commissions or fees, or the net amount of consideration, in its statement ofincome.
Revenue is recognized based on the transaction price under contracts with clients. If a contract contains multiple
performance obligations, the transaction price is allocated to each performance obligation at a ratio of standalone
selling price. Since consideration for transactions is usually paid within one year after the satisfaction of performanceobligations, such consideration does not include any significant financing component.
5. Accounting policy for translating foreign currency-denominated assets and liabilities into yen
Monetary receivables and payables denominated in foreign currencies are translated into yen at the spot exchange
rate on the balance sheet date, and the resulting translation adjustments are presented as foreign exchange gains orlosses.
6. Hedge accounting(1) Hedge accounting method

Deferral hedge accounting is adopted for hedge transactions.
Foreign exchange forward contracts are accounted for by theallocation method if the foreign exchange forward contracts
meet certain criteria to adopt the method.

(2) Hedging instruments and hedged items

Hedging instruments: Foreign exchange forward contracts
Hedged items: Accounts payable - trade(3) Hedging policy

To avoid future foreign currency fluctuation risk associatedwith foreign currency transactions, etc., JAPEX enters into
hedge transactions only in connection with the relevant
assets, liabilities and forecast transactions.

(4) Method of assessing the effectiveness of hedges

JAPEX assesses whether the critical terms of the hedging
instruments and hedged items are closely aligned, and thehedge transactions are effective in offsetting the pricefluctuation, etc. at the inception of the hedge and on an
ongoing basis. Forward exchange contracts accounted for by
the allocation method are not subject to the assessment ofhedge effectiveness.

Certified Public Accountant<Audit of Financial Statements>
OpinionPursuant to the provisions of Article 193-2, paragraph 1 of the Financial Instruments and Exchange Act, we have audited the consolidated
financial statements of Japan Petroleum Exploration Co., Ltd. (the “Company”) provided in the Financial Information section in the
Company’s Annual Securities Report, namely, the consolidated balance sheet as of March 31, 2023, and the consolidated statement ofincome, consolidated statement of comprehensive income, consolidated statement of changes in equity, and consolidated statement ofcash flows for the fiscal year from April 1, 2022 to March 31, 2023, and the notes to significant accounting policies for preparation of
consolidated financial statements and other notes and the annexed consolidated detailed schedules.
In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of theCompany and its consolidated subsidiaries (collectively, the “Group”) as of March 31, 2023, and its consolidated financial performanceand cash flows for the fiscal year then ended in accordance with accounting principles generally accepted in Japan.
Basis for Opinion
We conducted our audit in accordance with auditing standards generally accepted in Japan. Our responsibilities under those standards
are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We
are independent of the Group in accordance with the ethical requirements that are relevant to our audit of the consolidated financial
statements in Japan, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that theaudit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
Key Audit Matters
Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial
statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as awhole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Recoverability of Deferred Tax Assets
Key Audit Matters and the Reasoning

Auditor’s Response

As described in “Notes to consolidated financial statements,(Significant accounting estimates),” the Group recorded deferred
tax assets before offsetting deferred tax liabilities of ¥22,162
million as of March 31, 2023. Of the item above, the Company
submitting consolidated financial statements recorded deferred
tax assets of ¥11,788 million including ¥3,608 million
recognized for some part of net tax loss carried forward.
As a result of performing the scheduling of deductible temporary
differences based on the estimated taxable income before
adding/deducting temporary differences over the reasonably
estimable period as of the end of the current fiscal year, theGroup recorded its deferred tax assets for the recoverable
deductible temporary differences and net tax loss carriedforward.
The recoverability of deferred tax assets largely depends on theestimation of future taxable income. Selling prices and volumes
are used as primary assumptions for estimating the timing andamount of future taxable income.
E&P Business and Infrastructure/Utility Business are primarybusinesses of the Company. These primary assumptions are
significantly affected by irreversible structural changes anddecarbonization trends in various areas such as energy demandand environmental issues. These estimates largely depend on
business plans and also impacts the determination of reasonably
estimable periods of future taxable income according tocorporate classifications based on the Implementation Guidanceon Recoverability of Deferred Tax Assets (ASBJ Guidance
No.26). Such estimates entail uncertainties under which
management has difficulty making decisions and providing
evidence. In addition, deferred tax assets have significance interms of amount. Taking these matters into consideration, we
determined that recoverability of deferred tax assets of theCompany is a key audit matter.

For the purpose of considering the recoverability of deferred tax
assets of the Company, we examined the appropriateness of thecorporate judgments and reasonably estimable periods of futuretaxable income relating to corporate classifications based on the
Implementation Guidance on Recoverability of Deferred Tax
Assets (ASBJ Guidance No.26), including whether or not suchjudgements and periods satisfy the requirements of paragraph 29of the same Implementation Guidance. Since the reasons forhaving incurred significant net tax loss had been discussed in theprevious fiscal year, we discussed with management, weespecially discussed the business environment surrounding theCompany with its management and examined whether theCompany could show reasonable grounds that it would generatetaxable income before adding/deducting temporary differences
for approximately three to five years in the future.
Furthermore, to consider the appropriateness of the estimation of
taxable income for the following fiscal year, we discussed withmanagement the management environment and underlying
business plans, including the decarbonization trends, the effectof economic sanctions adopted against Russia and trends in thedomestic economy. We mainly performed the procedures below:– We compared the actual sales volumes with the estimatesformulated in the past to assess the effectiveness of theestimation processes determined by management.
– We considered the consistency between the estimates oftaxable income for the following fiscal year and the businessplans approved by management.
– We compared crude oil and natural gas prices, the basis ofselling prices, with estimated prices announced by external
research firms, and discussed with management the impact of
the economic environment, such as the decarbonization trends,
on the prices of crude oil and natural gas.
– We compared sales volumes with past results for each major
product and merchandise, such as crude oil, natural gas, andelectricity, and considered the consistency between production
amounts and the results of reserve assessment for crude oil andnatural gas.

inadequate, to express a qualified opinion with exceptions on the consolidated financial statements. Our conclusions are based on theaudit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease tocontinue as a going concern.
