In addition to complying with laws and regulations, we recognize that in order to fulfill our social responsibilities through our business activities, raising compliance awareness throughout the Group is a fundamental issue of corporate management. As a global corporate group, we continue to further enforce our group-wide compliance framework.
KDDI Group Compliance and Enforcement Framework
KDDI has established the KDDI Code of Business Conduct as a guideline to ensure that employees engage in ethical behavior with a strong awareness of compliance. To thoroughly disseminate and enforce the Code, in addition to publishing it on the intranet, KDDI also distributes a web shortcut related to the KDDI Code of Business Conduct to business mobile devices provided to employees, enabling them to refer to it at any time when they are uncertain about a decision. Furthermore, KDDI has established the KDDI Group Corporate Ethics Committee as the body responsible for deliberating and deciding on compliance-related matters within the KDDI Group.
The KDDI Group Corporate Ethics Committee is chaired by the Executive Vice President and Director, CFO (Head of Corporate Sector), and consists of members appointed by the chairperson as necessary. It meets twice a year, grasps the status of each KDDI Group company, and supports the establishment and strengthening of compliance frameworks.
In addition, under the KDDI Group Corporate Ethics Committee, it formulates policies for awareness-raising activities, addresses compliance violations when they occur, considers disclosure of information to external parties, and examines measures to prevent recurrence. The activities of the KDDI Group Corporate Ethics Committee are made public to all employees via the intranet.
Furthermore, the KDDI Code of Business Conduct, the promotion framework for its observance, violation prevention measures, and reporting system are subject to verification by an independent third party.

Initiatives for au Style/au Shops
As of the end of March 2023, there are 279 au Style stores (including directly managed stores) nationwide, 1,780 au Shops nationwide, and 238 UQ Spot stores nationwide, all of which specialize in KDDI products and services. These shops including au Style and au/UQ mobile Shops are the place where customers actually see and experience au/UQ mobile products and services. KDDI products and services are also widely available at Toyota car dealers and electronics retail stores in addition to au Style and au Shops.
We at KDDI consider that improving the service quality of au Style, au Shops and UQ Spot―as specialty stores for a telecommunications operator―and other au distributors to be particularly important to maximizing positive customer experiences. We continue to support them in various ways to further improve skills of the staff.
Since training staff is essential to improving the service quality of all distributors, we help the staff learn effectively through e-learning in which they can gain basic operational knowledge and new product information and online sales training. We have also implemented a qualification system to evaluate staff skills and store management capabilities and encourage their sales efforts to achieve high customer satisfaction by awarding the titles "Advisor," "Master," "Lifestyle Consultant (au Style only)" and "Expert." We train and certify "X Supervisors," who promote human resource development management at distributors. Moreover, we hold the "CX AWARD," an annual contest to present various initiatives at au Style, au Shops and UQ Spot, and share praise and good practices.
We also conduct periodic audits of au Style, au stores, and UQ Spot to check the status of implementation of operational rules for information security and legal compliance. By providing feedback based on the audit results, we are working to raise security and compliance awareness among staff handling personal information and improve the accuracy of our operations.
Support for Distributors
We at KDDI support our distributors in their various sales support activities. This includes our support when they open or move to new locations, in organizing staff for store operations, and in staff capacity building through various in-store staff training and qualification exams.
In its agreement with distributors, KDDI requires them to have no involvement in anti-social forces, engage in fair trade practices and conduct proper business activities.

Elimination of Organized Crime Groups (Basic Approach and Implementation Status)
KDDI Code of Business Conduct and Our Basic Policy for the Creation of Internal Systems take a firm stand on countering organized crime groups.
KDDI will respond to organized crime groups in accordance with the following guidelines:
- Organizational response
- Collaboration with external specialized agencies
- Complete severance of all relationships, including transactions
- Civil and criminal legal responses in emergencies
- Prohibition of transactions and funding
Preventing Anti-competitive Behaviors
The KDDI Code of Business Conduct defines rules that prohibit anticompetitive behaviors, and we make efforts to ensure that all employees comply with competition laws.
In addition to competition laws, we stipulate that local laws and regulations in each country and region on labor, tax, the environment, consumer protection and data protection must be examined thoroughly to ensure full compliance.
Furthermore, under the KDDI Group Sustainable and Responsible Procurement Guidelines, we demand our business partners to not engage in any activities that inhibit fairness, transparency or freedom of competition.
We respond promptly to requests and guidance received from the Ministry of Internal Affairs and Communications and other government agencies, ensure compliance with relevant laws and regulations, and maintain proper business operations.
Business Ethics Helpline (Whistleblowing System)
We established the Business Ethics Helpline in 2006 to serve as a contact point for all employees of KDDI and KDDI Group companies who have questions or concerns about business ethics including violations of regulations or laws. The helpline is available anytime and can receive reports through an internal or external contact point established in collaboration with external experts (reports can be received by e-mail, phone, or letter in multiple languages). We also accept anonymous consultations and declarations.
Cases reported or consulted are investigated by KDDI's compliance department with thorough consideration for privacy protection and confidentiality. If issues are identified as a result, they are promptly reported to senior management and corporate auditors, and corrective measures as well as recurrence prevention measures are implemented.
We operate the Business Ethics Helpline in accordance with the Whistleblower Protection Act, which was revised in June 2022, and our internal reporting procedures clearly state that no reporter or investigation collaborator should be treated unfavorably due to their reporting or cooperation in investigative facts.
In addition, we have established a "Harassment Hotline", a common contact point for the KDDI Group for reporting and consulting on all forms of harassment, including sexual and power harassment, which is handled by external professional counselors.
We are actively promoting the use of the Business Ethics Helpline and the Sexual Harassment and Human Relationships Hotline by distributing whistleblowing cards.
In FY25.3, none of the consultations or reports received from entire KDDI Group companies concerned serious issues that required external declaration.
Responsible Tax Practice
Basic Tax Policy
We at KDDI Group pursue the satisfaction and benefits of our customers while fulfilling our social responsibilities not only by complying with international rules and applicable tax laws and regulations in all operating countries and regions, but also by complying with and following the spirit of the law and paying tax appropriately to engage in tax fairness, and thereby strive to maximize corporate value.
In fiscal 2024, we paid 338,517 million yen of corporate income tax, which accounts for 30.6% of gross income. KDDI Group submits the Securities Report after undergoing accounting audits by external accounting auditors and obtaining approval of the CFO (Senior Managing Executive Officer, Director /CFO Executive Director, Corporate Sector) and the President.
Tax Governance Structure
The KDDI Group Tax Management Regulations have been established to ensure that the KDDI Group steadily implements the Basic Tax Policy in its actual business activities. KDDI Group companies are required to comply with the regulations. The regulations were established by KDDI and are overseen by the Chief Financial Officer.
Practical operations are transferred to KDDI's tax division, which reports to the CFO and the necessary meetings bodies when it becomes aware of significant events or risks related to the KDDI Group's tax affairs.
Initiatives to Maintain and Improve Tax Governance
As KDDI Group businesses become increasingly multinational and have more international transactions, our top management, including the President, is working to develop and promote a tax strategy that properly recognizes international tax risks and regards such risk as an important issue that is directly linked to management, while utilizing external specialists to have a deeper understanding of the latest tax updates. In addition, the head office is engaged in education for employees across the world and receives tax practice support from external specialists. With these initiatives, we strive to maintain and improve tax governance. Also, with regard to the tax returns it prepares, KDDI has them reviewed by an external tax accountant corporation and obtains approval of the CFO before submitting them to the tax authorities.
Tax Transparency and Relations with Tax Authorities
To maintain the transparency of tax affairs, we prepare and submit an annual report on our activities by country in accordance with tax laws in Japan. We also work to build trust relationship with tax authorities in each country by conducting timely and appropriate disclosure of tax-related information, such as a business summary report on the overall status of the Group's activities in line with the relevant laws, regulations and disclosure standards of each country and region in which we operate. With these initiatives and prior inquiries as required, we strive to reduce tax risks.
Efforts to Prevent Tax Avoidance
In accordance with OECD's Action Plan on Base Erosion and Profit Shifting (BEPS), we are committed to ensuring proper tax payment in all operating countries including Japan, by aligning tax payments with the location of our economic activity and value creation, in line with the revision of tax regulations to tackle BEPS.
In particular, we handle transfer pricing taxation and anti-tax haven taxation, which are critical international taxation issues.
Transfer Pricing Tax Compliance
The KDDI Group's business is primarily in telecommunications and ancillary businesses in Japan, and its foreign-related transactions are few compared with those of other multinationals of similar size.
Where foreign-related transactions are conducted, the prudence of the foreign-related transaction is confirmed in compliance with the laws and regulations of the relevant countries, and transfer pricing documentation is prepared. Additionally, depending on the size of the foreign-related transaction, we pay the appropriate taxes by utilizing various systems in consultation with the tax authorities.
Tax Haven Tax Compliance
We do not use tax-free or low-tax jurisdictions (so-called "tax haven jurisdictions") for tax avoidance. When an investment is made in a tax haven area for business reasons, the anti-tax haven taxation system is applied following the laws and regulations of the relevant countries. If the company is subject to anti-tax haven taxation, it will file the appropriate tax return and pay the tax due.
