KDDI Occupational Safety and Health Policy
We, the KDDI Group, uphold the corporate philosophy of “pursuing both the material and emotional well-being of all our employees while delivering overwhelming excitement that exceeds our customers’ expectations, thereby contributing to the development of a rich communications society.” To remain a happy and vibrant company for all employees working at the KDDI Group, and to continue providing services as a comprehensive telecommunications operator that supports society’s information infrastructure, we consider it our top priority to ensure the “safety” and “health” of each and every employee and to create a comfortable, lively, and employee-friendly workplace environment.
Accordingly, with the approval of the President and CEO, we have established the “KDDI Occupational Safety and Health Policy” (hereinafter, the Policy). Under this Policy, we ensure the safety and health of workers in the workplace (all employees engaged in business activities, dispatched workers, contractors, etc.), promote the creation of a comfortable workplace environment, and address occupational safety and health across the entire KDDI Group.
- Scope of Application
This Policy applies to all our business activities and extends not only to all employees but also to all contractors and individual proprietors under our supervision.
- Compliance with International Standards and Laws
We comply with international standards related to occupational safety and health, domestic and overseas laws and regulations, voluntary safety programs, and labor agreements, and implement them rigorously.
- Dialogue and Consultation with Workers
Through active dialogue and consultation with workers or their representatives, we strive to improve safety and health management.
- Setting Goals and Continuous Improvement
We set quantitative targets to measure the effectiveness of occupational safety and health, strengthen initiatives to achieve them, and continuously evaluate and improve them, thereby promoting the enhancement of safety and health levels across the organization.
- Development of Action Plans
We clarify occupational safety and health goals and formulate action plans based thereon. This enables effective risk management and accident prevention.
We will continue to work in collaboration with all stakeholders to maintain and improve a safe and healthy workplace environment in accordance with this Policy.
- *Initiatives for Occupational Safety and Health at Suppliers
Regarding occupational safety and health at suppliers, we have separately established the “KDDI Group Sustainable and Responsible Procurement Policy” and “KDDI Group Sustainable and Responsible Procurement Guidelines”, and will promote understanding, cooperation, and compliance therewith.
Framework
We comply with the “Safety and Health Management Regulations” and the “Labor Agreement,” and at each workplace, we appoint a general safety and health manager, safety manager, health manager, safety and health promoter, health promoter, industrial physician, mental health promotion officer, and safety and health committee members to establish a safety and health management system.
Planned and operated jointly by labor and management, the “Safety and Health Committee,” held once a month at each workplace, discusses themes such as “health management,” “healthcare,” “mental health,” “work style reform,” “overtime and long working hours,” “fire prevention and disaster preparedness,” and “traffic safety” to identify risks and discuss countermeasures. Furthermore, by undergoing internal audits of occupational safety and health initiatives, we continuously improve workplaces.
In addition, under the “Health Management Declaration,” to promote employee health enhancement, which is the core of health management, KDDI, the KDDI Health Insurance Society, and the KDDI Labor Union work together to advance the physical and mental health of employees.

Safety Management during Construction of Base Stations and Operation and Maintenance of Facilities
Goals
Number of Occupational Accidents (Number of serious accidents (death or leave of absence of 4 days or more))
ZERO
At KDDI, we implement a variety of initiatives to prevent occupational accidents at construction and work sites. Through these initiatives, we aim to achieve “zero accidents and zero disasters” and continuously strive for improvement and enhanced safety awareness.
Enhancing Safety Awareness and Information Sharing
Safety Convention
We regularly hold safety conventions for partner companies and internally to raise safety awareness, share safety measures, and prevent the fading of accident memories.
Safety Liaison Meeting
We periodically hold meetings to share information on safety measures, targeting departments in charge of Construction Business Act projects, qualified personnel, headquarters project managers, and key personnel from major business partners.
Safety and Health Council
We hold a monthly regular meeting on safety to share the latest safety information.
Strengthening Education and Training
Diverse Training Programs
We conduct classroom lectures and hands-on practical training tailored to the level of participants, including new employees, transferred employees, existing employees, and qualified personnel.
In hands-on practical training, we cover a wide range of topics from basic to specialized knowledge in the construction industry-such as high-altitude work, ceiling wiring, platform installation, and the use of electric tools-and provide training directly linked to actual work to ensure safety.
Training in Compliance with Laws and Regulations
We also conduct various legal training sessions in response to legislative revisions, such as training on asbestos.
Streamlining Safety Management and Information Dissemination
Preparation and Dissemination of Safety and Health Documents
We promote efficient safety management by disseminating the latest information on safety management and legislative revisions, and by renewing the portal site for construction work and releasing tools to support the creation of safety documents.
Initiatives at Work Sites
Safety Patrols
We conduct more than 1,000 site patrols annually, performing inspections from a third-party perspective. This ensures thorough safety management at sites and contributes to the prevention of occupational accidents.
Near-Miss Activities
By promoting the use of the near-miss system and holding near-miss workshops, we strive to enhance daily safety awareness and detect issues early.
Other Specific Measures
- (Heatstroke Prevention Measures)
We implement measures such as promoting air circulation with industrial fans, setting regular hydration breaks, lending watches to reduce heatstroke risks, and distributing heatstroke tablets/candies and sports drinks.
- (Awareness-Raising Meetings)
We hold sessions to familiarize workers with work procedure manuals and overall awareness meetings hosted by prime contractors to promote sharing and understanding of work procedure manuals, thereby thoroughly ensuring site safety through the dissemination of various information.
Continuous Improvement and Cooperation
Safety HUB Activities / KDDI-Partners Study Group
We share activities among partner companies, discuss joint safety measures, exchange opinions on construction methods, and strengthen collaboration with partner companies as well as safety and health initiatives.
Construction Method WG
We establish a working group to examine construction methods that enhance safety and promote the standardization of safety practices.
Through these initiatives, we aim to create a safe and comfortable working environment, strive for excellence in safety and health management, and continue to make ongoing improvements while further strengthening safety measures.
Priority Measures Relating to Occupational Health and Safety
We respect human life and are committed to ensuring the safety of employees in the workplace, promoting their physical and mental health, and maintaining a comfortable working environment. Based on this philosophy, we are advancing various initiatives to promote “Health-Focused Management”.
Preventing Long Working Hours
To prevent long working hours and ensure compliance with the 36 Agreement, the Human Resources Department sends individual warning emails and shares information about targeted employees with the heads of each headquarters and HR personnel. In addition, we regularly hold seminars on work hour management and harassment to address the risk of legal violations.
Establishing a Safety and Health Management System
To thoroughly comply with laws and regulations and protect the safety and health of employees, we have created a “Guide to Establishing a Safety and Health Management System.” We continuously improve the safety management system at existing offices and ensure that appropriate safety and health management systems are established when launching new offices.
Creating a Comfortable Workplace Environment
To maintain and improve a comfortable workplace environment, we conduct legally required air quality measurements every two months, measuring temperature, humidity, airflow, carbon dioxide, carbon monoxide, and airborne dust. If any abnormalities are detected, we collaborate with the building management company to perform ventilation, cleaning, and other necessary actions. In addition, during monthly workplace rounds by industrial physicians, we assess not only hygiene conditions but also lighting, noise, and other workplace environment factors, and implement improvements as needed.
Furthermore, during the annual “National Safety Week,” safety and health committee members at each office lead workplace inspections to identify and correct hazardous areas. At safety and health committee meetings, we share accident cases to prevent recurrence.
Since fiscal 2020, we have abolished smoking rooms in all offices to reduce the risk of passive smoking.
Strengthening Heatstroke Prevention Measures
To strengthen heatstroke prevention, we have established a system for early detection of heatstroke and created “System and Response Flow” procedures for preventing severe cases. We have disseminated this basic flow to relevant internal departments to promote employee health protection.
Furthermore, to ensure that employees work healthily and vibrantly, and that the company remains dynamic, we have established promotion points and target values as health indicators and are actively pursuing Health Management to achieve these goals.
Initiatives to Promote Employee Health
Conducting Health Examinations Beyond Legal Requirements
KDDI conducts regular health examinations with more detailed items than legally required, achieving a 100% implementation rate in fiscal 2024.
For post-examination follow-up, we provide email notifications to all employees with findings. For those with severe findings, we issue an “Urgent Medical Consultation Recommendation,” resulting in 100% consultation rate in fiscal 2024. Among those receiving the urgent recommendation, employees with particularly severe conditions are designated for “Improvement Recommendation.” After confirming results with their supervisors, we arrange industrial physician consultations as promptly as possible, provide guidance, and consider work restrictions as necessary. In addition to the company subsidy program for comprehensive medical checkups, we fully subsidize breast cancer screenings for female employees aged 35 and above. Since fiscal 2023, we have also introduced full subsidies for cervical cancer screenings for female employees aged 20 and above.
Furthermore, for employees who had lifestyle-related disease findings in the previous year’s examination and wish to participate, we offer the “Pre-Checkup Challenge,” in which public health nurses provide guidance before the next examination. Each year, 20-30% of participants achieve a reduction in findings.
We also actively promote measures to prevent disease progression (data health planning) in collaboration with the KDDI Health Insurance Society.
The KDDI Health Insurance Society provides group-wide specific health guidance (active support and motivational support), and we continue initiatives such as ongoing email support to improve completion rates. To further promote health, the union dispatches lecturers for health seminars at workplaces and offers health programs including free dental checkups and smoking cessation support.

| Discounted Sports Club Membership Program offered by the KDDI Health Insurance Society |
Confirmation of Employee Safety in Emergencies
In the event of large-scale natural disasters (earthquakes, typhoons, heavy rains, etc.), fires, terrorism, or widespread outbreaks such as a new strain of influenza, we have established a system to promptly confirm employee safety using the safety confirmation system and take appropriate actions based on the situation.
The status of safety confirmations is centralized by the Human Resources Headquarters, and updates are continuously reported to the Disaster Response Headquarters until the safety of all targeted employees is confirmed. We ensure employee safety by taking appropriate measures.
In addition, to enable rapid safety confirmation during emergencies, we conduct training using the safety confirmation system twice a year for all employees.
[Safety Confirmation Flow]
(In the event of an earthquake with a seismic intensity of 6-lower or higher, the system automatically sends notifications to immediately confirm the situation.)

Responses to Workplace Injuries
KDDI has established a system whereby any workplace injuries are reported via designated reporting channels, promptly investigated and actions are taken including putting measures in place to prevent recurrences.
For accidents involving falls, which are the most common cause of workplace injuries, we have prepared materials summarizing examples, contributing factors, and countermeasures. We are also promoting awareness of the accident reporting flow, encouraging employees to take precautions, and raising awareness of how to prevent accidents.
Safety and Health Management for Employees and Their Families Transferring Overseas
We conduct various activities aimed at ensuring the health and safety of employees working outside Japan. We provide consultations with industrial doctors to employees before they transfer overseas, interviews with medical staff to all employees returning to Japan and follow-up care after the regular health exams to employees working overseas. We also began conducting stress check for employees working overseas and providing follow-ups, including health checks as required. Furthermore, we have established and implemented the Vaccination and Health Report Guidelines for International Transferees and Business Travelers from the perspective of health management and employee safety for those transferring or traveling outside Japan.
We introduced a medical return program that covers the expenses of employees or accompanying family members returning sick or injured to Japan, if an industrial doctor judges that they should receive treatment in Japan. In preparation for emergent situations, we have set up emergency evacuation services for all employees stationed or on a business trip overseas for evacuating in the event of terrorism or political instability. We also offer emergency medical transport services for the transport of severely ill or injured persons to a different country for medical treatment if necessary.
