Health and Safety
For Kioxia Group to achieve sustainable development in harmony with society, the physical and mental well-being of each employee serves as an important foundation for our business activities.
Kioxia Group has established health and safety as priority areas of focus in terms of ensuring the Group’s medium- to long-term growth (what we call Sustainability Materiality), and we strive to create a safe and comfortable working environment for all employees and others involved in our business.
Health and Safety Policy
Kioxia Group’s senior managers in Japan all pledge to ensure health and safety across our operations, a pledge that is shared with all employees. Kioxia Corporation established its Basic Policy for Safety and Health at the time of the company’s foundation in 2017, and reviews the policy annually to ensure it continues to meet the needs of the times. Based on Kioxia Corporation’s Basic Policy, Kioxia Group in Japan has subsequently formulated its own policy and is accordingly implementing a range of health and safety initiatives.
Kioxia Group companies overseas implement employee health and safety initiatives in accordance with the laws and regulations of their respective countries and regions.
Promotion of Occupational Health and Safety (OHS)
Kioxia Group in Japan deploys health and safety supervisors within the Administration Division of each group company to promote health and safety activities among employees. They report periodically on health and safety matters to the president of each group company. The Health and Safety Officer of the Human Resources and Administration Division of Kioxia Corporation summarizes these reports and shares the summaries with the President and CEO, and the Executive Officer in charge of Human Resources.

OHS Management System
Kioxia Group has obtained the occupational health and safety management systems certification (ISO 45001:2018) for its manufacturing and R&D sites. As it moves to comply with the requirements for this certification, the Group is making efforts to continuously reduce health and safety risks through risk assessment and compliance with relevant laws and regulations, and is making its health and safety management measures more visible.
Kioxia Group is also committed to ensuring health and safety are maintained throughout day-to-day activities, involving both group companies and their employees. Our efforts include the creation of small workplace groups, which undertake a variety of activities on an ongoing basis. These activities encompass workplace improvement programs, education and training to increase risk awareness among employees, and monitoring to ensure that appropriate practices are being followed. We integrate these activities into our implementation of health and safety management based on ISO 45001 standards.

Workplace Accidents
Kioxia Group in Japan strives to minimize the number of workplace accidents and monitor any occurrences. We use the “frequency of injuries resulting in lost working days” as an indicator of these efforts. In 2024, the frequency rate was 0.18, which was below the average rate of 0.67 in the electrical machinery and equipment manufacturing industries.
Kioxia Group in Japan will continue to implement further measures to prevent workplace accidents. As a top priority, risk assessments are conducted for all workplaces and tasks, focusing on operations where there is a high risk of serious injury or illness, as well as on the handling of hazardous or harmful chemical substances. In addition, we systematically manage and reduce risk by reviewing work methods, identifying and eliminating specific risks, renovating facilities, and providing education and training to employees.
Frequency of Injuries Resulting in Lost Working Time at Kioxia Group in Japan3
- 3 Frequency = Number of casualties due to work-related accidents / Total actual working hours x 1 million. Figures for all industries and the electrical machinery and equipment manufacturing industries are collated from the results of the “Survey of Industrial Accidents” conducted each year by the Ministry of Health, Labor and Welfare.
Health Management
As the environment in which Kioxia Group conducts business continues to change dramatically, we have been working on the implementation of health and safety measures for our employees, an investment which we see as essential for the future of the Group and the development of society (investment for health).
Kioxia Holdings Corporation issued its “Kioxia Group Health Management Declaration” in April 2023.
Kioxia Group Health Management Declaration
We firmly believe the health of our employees is essential in order to achieve our mission of “uplifting the world with ‘memory,’” and consider this to be one of our most important areas of management focus.

Health and Productivity Management Initiatives
We pursue the following initiatives in order to create an environment where employees can work in good mental and physical health. Each business site also proactively implements its own measures.
- We have established processes whereby physicians are deployed to comment on the results of medical check-ups covering lifestyle-related diseases such as high blood pressure and high blood sugar levels, allowing for consultations with medical personnel and intervention by physicians. In this way we aim to reduce the number of employees who leave the company as a result of absenteeism, extended leave or illness.
- We have set up a mental health consultation service and make its existence known to all employees. We also provide various training programs aimed at preventing stress-related illnesses.
- We are promoting collaborative health programs7 with health insurance societies to improve employees’ health literacy and to prevent or treat any instances of metabolic syndrome.
7 These are aimed at preventing disease and promoting good health for employees and their families in conjunction with companies and insurers.
