Evaluation Results


The evaluation confirmed that KDDI’s Board of Directors is operating properly and functioning effectively. The following two points received particular praise:

  • Management of the Board of Directors meetings utilizing the knowledge of outside directors The Company has fostered a culture in which outside directors can actively speak up at Board of Directors meetings.
    In addition, executives are responding sincerely to the opinions and questions of outside directors, and the Board of Directors is managed in a manner that takes advantage of the knowledge of outside directors from various backgrounds.
  • Discussions focused on sustainable growth and the medium-to long-term enhancement of corporate value
    Discussions are being held from a medium- to long-term perspective on themes such as the sustainable growth of the mainstay domestic telecommunications business, full-scale rollout of 5G, and value creation through the integration of telecommunications and life design, the previous mid-term management strategy.

Improvements from Previous Evaluation

In the previous meetings, each director and Audit & Supervisory Board member proposed various themes to be discussed in the process of formulating new Mid-term Management Strategy to ensure KDDI’s sustainable growth in a rapidly changing business environment, by holding discussions among directors and Audit & Supervisory Board members utilizing their diverse experiences and knowledge.
Based on this challenge, in 2021, we ensured time for the active and constructive exchange of opinions among executives and sufficient time for deliberations, and discussed various issues, including the proposed themes, for the formulation of the new Mid-Term Management Strategy.

Moving Forward

Through proactive initiatives based on the "Satellite Growth Strategy" with telecommunications at its core, KDDI continues to diversify its business domains and expand its business scale through an increase in the number of group companies.
In this environment, we believe that in order for the KDDI Group to fulfill its social responsibilities and achieve sustainable growth while appropriately responding to various risks, it is important to further strengthen corporate governance, which serves as the foundation for such efforts.
The Group as a whole will strive to further disseminate the "KDDI Group Philosophy," which serves as the foundation of its corporate activities, as well as strengthen its governance system, including risk management, while enhancing the effectiveness of risk management through timely and appropriate supervision by the Board of Directors.

Outside Director/Auditor Support System

To ensure active discussions in the Board of Directors meetings, we inform outside directors and Audit & Supervisory Board members at least 3 days in advance of the dates and agenda items and provide agenda materials for upcoming meetings to help them gain a deeper understanding of the agenda in advance.
In addition, we make the deliberations more substantial by accepting questions beforehand and preparing more extensive explanations for the meetings based on the questions.
We also provide a wide range of information outside the board meetings, including on business strategies, management status, R&D and technology. Specifically, each division’s general manager and Director provide detailed explanations of the general overview of the business and issues and regularly report on the management status of subsidiaries, we provide opportunities to visit in-house exhibitions of R&D achievements as well as the telecommunications equipment and network monitoring center and other workplaces. We also provide two reports every year on corporate ethics and risk management activities.
In addition, to enable outside directors to strengthen their ability to gather information, they are invited to attend meetings of the Audit & Supervisory Board when the auditing firm reports the results of the second quarter review and the year-end audit, and liaison meetings with Audit & Supervisory Board members are held twice a year.
To promote cooperation among outside directors, we hold liaison meetings exclusively for outside directors and liaison meetings for outside directors and part-time Audit & Supervisory Board members.
We aim to raise the effectiveness of the Board of Directors supervision of management and to invigorate discussions of management strategies at board meetings by providing a deeper understanding of our business through these initiatives.
We established the Audit & Supervisory Board Member’s Office, which supports Audit & Supervisory Board members, including part-time outside members.

Policies on Parent and Subsidiary Listings

One of KDDI’s subsidiaries, Okinawa Cellular Telephone Company (hereafter "Okinawa Cellular"), is listed on the Tokyo Stock Exchange Standard Market.Being committed to "growth as a group," KDDI aims to maximize mutual synergies and expand and strengthen new growth foundations for the entire group by maximizing the use of our assets and supporting the growth of group companies.
Okinawa Cellular was established with the cooperation of several prominent local companies, making it a community-based company that contributes strongly to the local community. Based on this background, we believe that there are the following advantages to having Okinawa Cellular as a publicly traded company, and we believe that it continues to be significant to have Okinawa Cellular as a listed subsidiary.

  • Returns to investors
    By implementing shareholder return measures as a listed company, Okinawa Cellular will be able to return profits to its investors, including local companies that cooperated in the company’s establishment and investors who have supported the company since its listing.
    Okinawa Cellular’s shareholder return policy should be determined in consideration of the interests of all shareholders, taking into account the balance between medium- and long-term business growth and shareholder returns, and its implementation will be determined at the company’s discretion as an independent listed company.
  • Contributing to employment in Okinawa prefecture and securing talented human resources
    Currently, many people from Okinawa prefecture have joined Okinawa Cellular and are playing an active role in the company.
    Given the geographical characteristics of Okinawa Cellular, we believe that the fact that its business area is limited to Okinawa prefecture meets the needs of people from Okinawa who wish to work locally, and the fact that Okinawa Cellular is a publicly listed company also helps us recruit talented personnel.
  • Promote the use of Okinawa Cellular’s services and increase subscriptions by earning the trust of Okinawa residents
    In addition to KDDI’s similar services, Okinawa Cellular also offers unique services based on local conditions. As a community-based listed company, we believe that we have earned the trust of people in Okinawa by operating our business in line with the expectations of the local community, and this has led to the promotion of Okinawa Cellular’s service use and increased subscriptions.

For transactions that may cause conflicts of interest, Okinawa Cellular determines whether to implement the transaction after multifaceted discussions by independent outside directors and independent outside auditors. Okinawa Cellular has also established a voluntary committee led by an independent outside director as an Advisory Committee to the Board of Directors to discuss director nominations and compensation, and decisions regarding management nominations and compensation are made after discussions by Okinawa Cellular’s independent directors/auditors to ensure transparency.
Through these efforts, we will ensure management transparency from the perspective of protecting minority shareholders, and at the same time meet the expectations of our shareholders by increasing corporate value and returning profits to shareholders.
KDDI will continue to respect independence and autonomy while mutually cooperating with Okinawa Cellular in business operations and development as a group.

Policy on Strategic Shareholdings

KDDI believes that participating in tie-ups with a variety of companies is essential to providing our customers with increasingly diverse and advanced services.
KDDI possesses strategic shareholdings if such possession will contribute to the sustainable growth of KDDI's business and the medium to long-term increase of corporate value.
Every year, the Board of Directors reviews all the pros and cons of continuing the possession of each individual strategic holding by judging its significance and economic rationale. When a strategic shareholding is found to have only tenuous significance, we will sell as promptly as possible.
The Company calculates the ratio of the contribution by the issuing company to the Company's profits within the most recent fiscal year.
The economic rationale is verified by comparing the ratio with the valuation of each strategic shareholding at the end of the most recent fiscal year, and confirming whether the ratio satisfies the capital cost standard established by the Company.
