Well-being Report
Health Management PDCA
Our employee health management program, which forms the basis of employee health management, has achieved a 100% participation rate in health checkups, and we also focus on optional examinations such as gynecological examinations and H. pylori testing.
Furthermore, we have built a cloud-based health management system to enable industrial physicians and public health nurses to accurately understand the health status of employees. By centrally managing employee health information and analyzing and evaluating health checkup results, we can provide personalized health guidance and mental health support.

Prevention of lifestyle-related diseases
As part of our focus on health management, particularly in addressing lifestyle-related diseases, we implement various guidance programs and campaigns to support employees in maintaining and improving their health.
If any abnormalities are found during a health checkup, we ensure that the employee is followed up with an industrial physician, a general practitioner, or a public health nurse, and, if necessary, referred to a medical institution to maintain coordination.
Collaborative Health Specific Health Guidance
As part of our collaborative health initiative, our group and Niterra Co., Ltd. Spark Plug Health Insurance Association have been providing specific health guidance to employees and those continuing their employment since 2021. For individuals with a BMI of 35 or higher or those at high risk, an industrial physician consultation is also conducted in addition to the initial interview.
Lifestyle-related disease prevention program "Health Up"
We have implemented a program called "Health Up" for employees with a BMI of 25 or higher. This program supports weight loss for health purposes through monthly physical data measurements, and involves continuous participation for approximately six months, including interviews with an industrial physician and guidance from a public health nurse, and has shown positive results.
Health seminar
We provide health information to our group employees both domestically and internationally, with industrial physicians and external doctors serving as instructors. Starting in 2025, in addition to the traditional web distribution, we introduced an e-learning system, creating a system where information can be viewed at any time without a time limit.
Strengthening mental health care

In addition to line care education through internal and external training, we conduct reading sessions of the "Self-Care Handbook" within the workplace to promote disease prevention and awareness of self-management. We also strive to promote mental health by conducting in-house training sessions and establishing a "Health Consultation Service" where employees who feel unwell can seek advice.
Furthermore, by conducting stress checks and analyzing the impact of the workplace environment on employees' physical and mental health, we strive to prevent mental health problems caused by stress and create a safe and secure work environment.
Prevention of passive smoking
Since April 2023, our company has completely prohibited smoking on the premises of all of our business locations in Japan.
We also provide support, including smoking cessation clinics, for those who wish to quit smoking.
Prevention and management of global health problems such as infectious diseases
Our group is committed to preventing and controlling the spread of various infectious diseases from the perspective of ensuring the health of our employees and business continuity. We maintain stockpiles of protective supplies such as masks and disinfectants, and we have established infection prevention measures in the workplace and guidelines for responding to outbreaks, and we are ensuring that all employees are thoroughly informed of these measures.
Furthermore, we are constantly monitoring and gathering information regarding the emergence of new infectious diseases.
Response to infectious diseases such as influenza and COVID-19
During outbreaks of infectious diseases such as influenza and COVID-19, we take appropriate infection control measures to prevent workplace outbreaks by sharing the latest trends, issuing warnings, and implementing other necessary precautions. Furthermore, to ensure a safe and secure work environment while simultaneously maintaining business operations, we have established and implemented guidelines for responding to infections and established work rules.
As part of our efforts to prevent infection and reduce the severity of severe cases, we have been continuously implementing workplace influenza vaccinations, and in the past, we have also contributed to preventing the spread of infection throughout society by providing workplace COVID-19 vaccinations to employees, their families, business partners, and local residents.
Vaccinations for overseas business trips and assignments
When employees travel abroad for business or assignment, they can receive vaccinations at the company's expense against infectious diseases that may be present in each country or region.
