KDDI's Commitment to Sustainability
KDDI Sustainability Management

KDDI's sustainability management seeks to create a virtuous cycle of business growth and social value creation. It is the foundation on which we continue to evolve our "power to connect."
At KDDI, "connecting" and "being connected" refer not only to the digital connections made possible by AI and various other technologies. They also reflect our commitment to "connecting and protecting lives," "connecting day-to-day lives," and "connecting hearts and minds."
At the center of these connections are people, each with a real life and a real way of connecting that is unlike any other. To support all these connections and create a future in which society as a whole―the sum of each and every individual―can continue to grow in a healthy and sustainable way, we have defined six areas of materiality to address. By addressing these issues, we will continue to foster the sustainable growth of both our business and the social value we create.
We want to expand the connections we offer to sustain lives, support daily living, and bring peace of mind. By offering greater stability, convenience, and comfort in daily life―as well as the creativity and innovation that empower people to take on new challenges―we seek to deliver true quality, value, and happiness.
At KDDI, we believe that telecommunications exist as part of society itself, deeply woven into the living fabric of human activity. Guided by this belief, we will continue to contribute to a sustainable society by increasing the total number*1 of pathways through which we connect and protect lives, connect day-to-day lives, and connect hearts and minds.

- *1"The total number of pathways through which we connect and protect lives, connect day-to-day lives, and connect hearts and minds" (the total number of pathways) refers to the total number of KDDI principal service users and customer touchpoints through which the company provides a foundation and environment for realizing its vision of a society in which everyone can make their dreams a reality. By addressing its material issues, KDDI will continue to expand the total number of pathways.
Sustainability Promotion Framework
Under a promotion framework in which the President of KDDI serves as the chair, Directors serve as standing members, and observers are appointed by the chair, we position sustainability as a pillar of management and advance our initiatives.
Improvements in sustainability are incorporated into company-wide KPIs and are linked to executive remuneration and bonuses for all employees.
The Sustainability Committee makes recommendations to the Board of Directors, which then approves and supervises sustainability activities.

Internal Engagement Initiatives for Implementing Sustainability Management
To ensure broad and continuous understanding of sustainability management across all levels―from senior executives to every employee―we have designed a step-by-step approach as shown in the diagram below. Through repeated initiatives, we continuously promote deeper understanding, aiming to foster new learning and awareness.
■Framework for Internal Dissemination (FY2025)
The KDDI Group Philosophy/KDDI Code of Conduct
The KDDI Group Philosophy, Group-wide Efforts
To ensure that all executives and employees can put the KDDI Group Philosophy and the KDDI Code of Business Conduct, which form the foundation of sustainability management, into practice in their daily work, KDDI annually conducts structured, tiered training and study sessions. Through programs tailored to each level, such as executive directors, leaders, members, and new hires, we promote understanding and practice of the corporate philosophy.
In addition, we ensure continued dissemination by distributing a shortcut to the online KDDI Code of Business Conduct to work devices and implementing compliance-related e-learning, among other measures.
Through these initiatives, we promote corporate activities in which each employee reflects the corporate philosophy in their own actions.
