Considering our obligation to occupational Safety and Health, we have implemented the following guideline: All the Komatsu Group companies, including all top managers and employees, shall promote occupational Safety and Health activities so that everyone can work in a safe and comfortable work environment in accordance with the policies described below.

The goal of the Health Culture is: to look after one's own health and the health of one's colleagues, and to consider and take action on what is necessary for leading a better life. The president announced the “Komatsu Health Declaration” in June 2014 to effectively promote this goal.
