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 safety, health, and health management as per the following structure.
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.
We shall share and discuss information on safety, health, and the environment in each region globally, leading it to the safe and healthy activities of each overseas subsidiary. In FY2024, we held the conferences in North America, Latin America, Europe, Asia and China.
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.”
Komatsu’s health initiatives began in earnest in 2014 with the announcement of the Komatsu Health Declaration and the launch of the Five-Year Health Development Plan. This plan was based on the belief that simply “managing” health is not sufficient for employees to lead fulfilling lives both during and after their careers. Instead, it aims to foster a culture of health in which employees are encouraged to pay attention to their own health and that of their colleagues, think critically about what is needed, and take proactive action—this is what we define as health literacy*.
In FY2019, we launched the Second Health Development Plan, which has been actively promoted in the years since. From FY2025, we have begun implementing the Third Health Development Plan, which introduces new initiatives.
In the latter half of the Second Plan, we expanded our efforts beyond the domestic Group to include overseas Group companies as well. As a result, our activities to build a global culture of health are steadily gaining momentum across Komatsu worldwide.

▷ Tobacco-related diseases
▷ Lifestyle improvement
Since FY2014, the Komatsu Group has implemented the Five-Year Health Development Plan to “implement outstanding health management” and “improve employees’ health literacy*.
In FY2019, the Second Health Development Plan was launched to further advance the initiatives of the previous mid-term plan. This plan promoted the development of a lifelong culture of health by enhancing support for work-life balance, strengthening primary prevention (such as improving lifestyle habits), and introducing ICT tools to improve health-related systems and environments.
Starting in FY2025, the Third Health Development Plan will be launched. Building upon the results and challenges identified in the Second Plan and the framework of the Health Management Map, we will continue to advance the creation of a culture of health throughout the company.

As part of the "Lifestyle Improvement Promotion" of the "Second Health Promotion Plan," in FY 2021, we launched the Komatsu Health Promotion 100 (KHP100) in cooperation with the Komatsu Health Insurance Association to further promote employees’ health and health literacy.
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 2025” by the Japan Sports Agency in recognition of its initiatives such as KHP100, which aim to promote employee health. This marks the second consecutive year Komatsu has received this award, following its first in 2023.
The "Sports Yell Company" is a system that recognizes companies that are actively engaged in promoting sporting activities to enhance employees’ health, encourage hard-working people to play sports, and foster social momentum for sports.

Komatsu published its first Health & Well-being Report in July 2025, with the aim of introducing and disclosing its health-related initiatives and data both internally and externally, thereby raising awareness and enhancing employee consciousness around health and well-being. The report outlines Komatsu’s objectives, policies, and progress in promoting health and well-being, along with related initiatives, achievements, and data. Going forward, we plan to publish the report regularly in line with the progress of our health promotion plans.
