Reduction of Hazardous Chemical Substances

At Mizuno, the Health and Safety Committee, under the leadership of the Human Resources and General Affairs Department, drives initiatives to reduce the use of, and replace with safer alternatives, chemical substances that may pose risks to human health and ecosystems. Each business site conducts risk assessments of chemical substances, evaluating their hazards and toxicity by category, and promotes the substitution of high-risk substances with lower-risk alternatives.

In fiscal year 2025, there were no major leaks of hazardous chemical substances from Mizunoʼs manufacturing facilities. In addition to its production sites, Mizuno also promoted risk assessments of chemical substances used for repairs at offices and retail stores.

For more information about Mizunoʼs system for managing hazardous chemical substances to ensure the safety and quality of its products, please refer to the “Ensuring Product Safety and Quality” page.

As part of its efforts to minimize health risks to workers, Mizuno is working to reduce toluene emissions by replacing adhesives containing toluene—used in shoe manufacturing—with water-based alternatives. In addition, since the end of January 2026, all undercoat paints used for badminton rackets produced at Mizuno Technicsʼ Yoro Factory have been converted to TX (toluene- and xylene-) free formulations.

The Law Concerning Special Measures against PCB Waste requires business operators storing PCB waste to submit an annual report on its storage and disposal status and to complete its disposal by the end of March 2027.
Senotech Corporation currently stores one transformer containing low-concentration PCB. The transformer has already been replaced and is awaiting disposal, and the company submits the required report on its storage and disposal status to the relevant local authorities every June.

• Mizuno is committed to using materials that do not contain hazardous chemical substances, starting from the design stage of the manufacturing process.
• Mizuno's ultimate goal is to switch to paints and adhesives that do not contain organic solvents. If an immediate switch is not possible, Mizuno will transition to ones that contain solvents with lower levels of hazard.
