Occupational safety and health is a core component in Komatsu's business operations. In line with this commitment, Komatsu thus enhances safety at the workplace for our employees and business partners.
The Komatsu Group promotes occupational safety and health, as well as health management, under the structure shown below.
The status and challenges of occupational safety and health, as well as health management, are discussed by the Board of Directors on a regular basis and whenever necessary.
The Komatsu Group holds various meetings to discuss and share information on safety, health, and health management, including the following:
This conference convenes with the aim to increase awareness regarding safety and health for employees of the Komatsu Group and partner companies while raising the level of safety and health activities. It involves sharing activity policies, priority items, and outstanding safety and health activities, and disseminating this information within individual departments. The conference also includes the presentation of presidential awards related to safety and health.
This committee, comprising both labor and management, investigates, deliberates, and decides on fundamental measures to eliminate workplace risks and prevent health hazards.
In each global region, including North America, Latin America, Europe, Asia, and China, Komatsu shares information and holds discussions on safety, health, and environmental topics. Through the safety and health activities of each overseas subsidiary, these conferences help improve the safety and health level of the entire Group.
This committee consists of business owners and employees (organized by Komatsu Union) as well as the Health Insurance Society. This occasion affirms a common recognition of "Health", and formulates measures and policies aimed to enhance the health care for employees and their families.
As a guiding principle for employee actions, “Safety & Health, Compliance, Quality, Delivery, Cost” are prioritized, with safety and health taking precedence. Additionally, based on the President’s “Message concerning Occupational Safety and Health,” the entire group is committed to ensuring a safe and secure work environment and promoting the maintenance and improvement of employee health. To achieve this, all employees work together to actively advance safety and health management activities under the established “Safety and Health Policy.”
Since 2014, Komatsu has been implementing its “Five-Year Health Promotion Plan.” This initiative aims to develop employees’ health literacy*, or their ability to pay attention to their own health and the health of their colleagues, consider necessary actions, and put them into practice, so that they can lead healthy and fulfilling lives not only during their employment but also after retirement.

Under KHP100, we distribute wearable devices to employees who wish to use them to visualize their physical activity and exercise. We also offer walking and other health events on a health portal that can be linked to the device, providing employees with opportunities to change their health-related behavior.
Komatsu has been certified as a “Sports Yell Company 2026” by the Japan Sports Agency in recognition of its initiatives such as KHP100, which aim to promote employee health. This marks the third time Komatsu has received this certification, following its certifications in 2023 and 2025.
The “Sports Yell Company” program certifies companies that actively promote sports activities to improve employee health, with the aim of promoting sports participation among people in their prime working years and fostering broader social momentum for sports.
