Target Health Management and Promotion Framework

1. Target Health Management

KDDI establishes promotion points as health indicators and plans and implements measures to achieve targets, enabling employees to work healthily and energetically while ensuring the company remains dynamic. We aim to foster a culture and environment where employees can work with vitality, thereby realizing the maximization of individual and organizational performance.

2. Health Management Promotion Framework

To promote employee health enhancement, which forms the core of health management, the company, the KDDI Health Insurance Society, and the KDDI Labor Union will work together as one to promote the physical and mental health of employees.

This organizational chart shows KDDI's health and work-style reform system, headed by the Chief Health Officer. The Human Resources Division plays a central role, coordinating with the Work Style Reform Promotion Committee, various departments, the Health Insurance Union, and the Workers Union.

Health-Focused Management Strategy

This flowchart shows how KDDI's "Health investment" initiatives lead to "Health investment effects," driving "Organizational revitalization and productivity improvement" and ultimately creating both "Social Value" and "Corporate Value."

Specific Initiatives

<Overview of Specific Initiatives for Health Management>

Under our health management strategy, we are implementing specific initiatives in the following categories:

1. Enhancement of Employee Engagement

(1) Implementation and Utilization of Engagement Survey

KDDI believes that enabling each employee to work vibrantly and enjoyably leads to the company's sustainable growth, and therefore conducts the Employee Engagement Survey on a regular basis.
In FY2024, 98.0% of targeted employees responded to the survey. The overall engagement score has continued to rise since the current survey began and has maintained the sustainability medium-term target of "72 or above" since FY2021. In particular, the key drivers of "relationships," "support," and "recognition" have improved, which we believe is due to the building of trust through regular 1-on-1 meetings between supervisors and team members, as well as support for work and career development.

(2) Interviews with all employees by in-house counselors

■ Implementation of Interviews with All Employees

In-house counselors conduct interviews with all employees to listen to their concerns regarding health conditions, work, workplace environment, human relationships, and other matters. These interviews are conducted twice a year (30 minutes per person) in the first and second halves of the fiscal year, achieving a 100% implementation rate in both periods.
In addition, to ensure appropriate attendance management, we confirm employees' attendance records, accurately track working hours, and prevent unpaid overtime (by thoroughly paying overtime allowances). Following the interviews, if signs of mental health issues or prolonged working hours are identified, we collaborate with medical professionals and organizational leaders to address them. We also provide feedback on employee voices to relevant organizations and departments, discussing solutions at the Work Style Reform Promotion Committee. Furthermore, to enhance the knowledge and skills of in-house counselors, we conduct questionnaires for interviewees.

This diagram visualizes the two-part structure of the employee support system: the direct support flow for employees and the feedback loop that uses "Voices of Employees" to drive improvement.
■ Activation of Experienced Employees through the In-House Counselor System

The in-house counselors who conduct interviews with all employees are experienced personnel with extensive knowledge and expertise, such as former line managers or certified professionals*6.
By leveraging the skills and human capabilities cultivated through their careers, they contribute to employee happiness and health. At the same time, they provide comprehensive support for autonomous and highly productive work through counseling. This system also serves as an opportunity for seasoned veteran employees to play active roles.

<Voices from In-House Counselors>

Points of fulfillment

"I feel a sense of fulfillment when I can support employees who are facing various concerns to take a positive approach to their work."

Skills utilized in the role

"I obtained the company-recommended industrial counselor qualification through continuous study and apply listening and response techniques in interviews."

Future career goals

"I want to continue carefully supporting each employee's career development, not only in terms of mental health but by staying close to their individual needs."

2. Appropriate Management of Working Hours and Reduction of Long Working Hours

(1) Operation of the Work Style Reform Promotion Committee

KDDI has been fully promoting work style reform initiatives since January 2017 by setting labor-hour indicators and taking other measures to drive fundamental changes in awareness and behavior from conventional working styles and shift to a highly productive way of working. At the same time, we established the Work Style Reform Promotion Committee. The committee consists of general managers who serve as the heads of each department, with the executive officer in charge of human resources appointed as chairperson. Since April 2018, presidents of strategic subsidiaries have also joined the committee, enabling the Human Resources Division and all departments to work together as one to advance work style reform.

Participants: 440 in total Satisfaction rate: 92.0%

■ Nationwide Health Seminars

To improve employee health literacy, address individual health concerns, and promote health-building initiatives, we held online seminars nationwide. Announcements were shared via the company intranet, allowing employees to attend the seminars of their choice.

(2) Promotion of Establishing Exercise Habits

■ Sports Events Using Health App for Health Enhancement

Since 2019, KDDI has distributed a health app to company-issued smartphones.
We regularly hold team-based walking events, with the number of participating teams steadily increasing. It has been confirmed that app users and event participants contribute to the rise in employees who exercise "at least 30 minutes twice a week." Health points are also awarded through the app.

■ Hosting of In-House Sports Festival "KDDI Sports Festival"

KDDI, in collaboration with the KDDI Labor Union, holds the in-house sports festival "KDDI Sports Festival." This event, ongoing since FY2013, aims to promote exercise, revitalize organizations, and foster a sense of unity among KDDI Group employees and their families through interaction and deeper understanding of the company.
The milestone 10th event in FY2024 was held in person at Tokyo Big Sight for the first time as the main venue, complemented by pre-competition caravans at 10 regional branches nationwide and YouTube live streaming, attracting approximately 2,300 participants and 2,000 online views.
On the day, teams united in competitions including giant ball relay, dancing ball toss, costume race, three-line tug-of-war, long-rope jumping, treadmill relay, muscle championship, video contest, and a company-wide quick-response quiz. We also held an all-employee "Color Team Walking Challenge" using the same health app as the walking events, contributing to both health enhancement and organizational unity.

■ Regular Health Checkups and Health Guidance (Before/After Regular Checkup/Specific Health Guidance)

The participation rate for regular health checkups in FY2024 was 100%, with a total cost of approximately ¥240 million for conducting the checkups.
For employees with abnormal findings in lifestyle-related disease items (blood pressure, glucose metabolism, lipid metabolism, liver function), we provided health guidance to over 1,350 employees annually, resulting in improvement for 79.0% of them.
The abnormal findings rate is also trending downward among employees who did not receive health guidance.
