Promotion Framework
NGK's Health Management Promotion System is overseen by the Director responsible for the Human Resources Department, under the oversight of the Board of Directors through the HR Committee.
With the Health Management & Promotion Office at its core, we collaborate with health professionals, including industrial physicians and industrial health nurses, while incorporating findings and deliberations from the Environment, Safety & Health Committee and employee views gathered through the Labor Union. Working in collaboration with the health insurance association, we plan, promote, and evaluate health management measures across the entire company.

Initiatives to Reduce Total Working Hours
Reducing Long Work Hours
NGK has established internal caps on overtime of 70 hours per month and 300 hours per half-year to limit excessive working hours and ensure employee health. Under this policy, we generally prohibit overtime when working seven consecutive days or on our twice-weekly Refresh Days, and require advance approval in unavoidable cases. We also require a rest interval of at least 10 hours following late-night work, among other measures to reduce employee workload.
In FY2025, there were 30 cases of overtime work exceeding our upper limit, but no cases which violated legal regulations (Full year results excluding seconded employees).
- Exceeded 70 hours: 9 cases (including 0 general employee)
- *Statutory limits not exceeded
- Exceeded 300 hours: 21 cases (including 10 general employees)
- *Statutory limits not exceeded
Working Hours Optimization Through Labor-Management Cooperation
NGK annually discloses working hours and leave usage to the Labor Union to exchange views and discuss countermeasures. When overtime is projected to exceed 45 hours per month, we identify the causes through Labor-Management Consultations and take measures such as distributing work periods and workloads more evenly and increasing headcount. When excessive working hours actually occur, we consult with the Labor Union at the workplace level on a case-by-case basis to address the issue.
For employees on overseas assignments, when excessive working hours are identified, we require a written explanation and a health checkup to maintain their health and analyze and address the root causes.

Following Up on Employees Working Long Hours
NGK provides employees working long hours, including non-regular and part-time employees, with ongoing opportunities to meet with industrial physicians for health consultations and exams. The results are reported at monthly Safety and Health Committee meetings at each worksite to thoroughly promote the reduction of overtime work.

Health Management when Stationed Overseas and Response to Infectious Diseases
NGK supports employees on overseas assignments and their accompanying family members, as well as approximately 600 employees on overseas business trips annually, to help them live and work safely and in good health. Through training by physicians specializing in travel medicine, we provide precautions for daily life, basic knowledge of infectious diseases, and vaccination recommendations, while strengthening health management, including measures against infectious diseases such as HIV/AIDS, malaria, and tuberculosis.
We also work with external medical consultants to offer medical consultations overseas, interpreter services at local medical facilities, and emergency medical evacuation. Following travel, we continue to provide support through regular health information updates and a consultation helpdesk that includes mental health support.
Furthermore, with regard to overtime worked by employees on overseas assignments, we apply the same monthly limit of 70 hours as in Japan. If this limit is exceeded, we conduct health questionnaires and consultations with industrial physicians to ensure thorough health management.
