Environmental Management System

To promote environmental protection activities across the Group, Mizuno has established an environmental management system, led by its executive officer.

As part of its environmental management system, Mizuno has established the CREW21 Environment Committee, chaired by the Managing Executive Officer in charge of Legal Affairs, with the Executive Officer in charge of Human Resources and General Affairs and the Senior Managing Executive Officer in charge of Product Development serving as vice-chairpersons.
The Committee discusses matters such as the formulation and revision of environmental policies, the establishment of short-, medium-, and long-term environmental targets, and the implementation of specific measures to achieve those targets.
The CREW21 Environment Committee meets regularly and advances environmental conservation activities through company-wide communication and collaboration.

For the primary roles and responsibilities of each organization, please refer to the “Sustainability Governance Structure” section.

Sustainability Governance Structure

The Mizuno Yoro Factory (now Mizuno Technics Corporation), Mizuno's main production site in Japan, became the first in the sports industry to obtain ISO 14001 certification in 1997. This initiative was later expanded to other domestic offices. In 2004, Shanghai Mizuno, the company's largest overseas production base, obtained certification, followed by Taiwan Mizuno in 2008. In 2015, Senoh Corporation and Senotech Corporation, which had joined the Mizuno Group, also received certification.

ISO 14001 certification is primarily applied to sites with significant environmental impact. As of March 10, 2026, the certification coverage rate is 79% for domestic sites and 31% for overseas sites, based on employee numbers.

Based on ISO 14001, the Mizuno Group conducts internal audits and undergoes external audits by the certification body once a year. According to the examination conducted by the certification body in the fiscal year 2025, Mizuno had no major issues. In addition, Mizuno has already completed resolving all minor issues.

To comply with environmental laws and regulations, Mizuno maximizes its environment management system and identifies environmental risks that could be underlying its business. Whenever a risk is identified, to prevent accidents and minimize danger, Mizuno regularly performs maintenance and inspection of equipment and facilities and also conducts emergency response drills.

In fiscal year 2025, Mizuno was not found as violating any environmental laws and regulations, did not experience any major accidents, and was not charged any penalties.

Mizuno strives to prevent environmental impact and reduce the environmental burden at every stage of the process, from planning and development to manufacturing.
In fiscal year 2018, Mizuno conducted an analysis using a life-cycle assessment (LCA) for WAVE RIDER 21, a representative model of running shoes in its footwear business, identifying the processes and environmental aspects that have significant impacts within the product's lifecycle.

In fiscal year 2021, Mizuno carried out LCA analyses on representative products by category, estimated their respective greenhouse gas emissions, and is utilizing these findings in future measures.

The Mizuno Group provides environmental education to all employees to raise individual awareness of environmental issues. Each department conducts its own training sessions, which help employees understand the company's approach and goals regarding environmental conservation, while also covering a wide range of annual topics.

In addition, specialized training is provided at each site to improve the skills and knowledge required for specific roles, such as waste management personnel and organic solvent users.

Mizuno discloses environmental information on its website. The sustainability report, which includes environmental information, is available in both Japanese and English. The information disclosed on the website can be downloaded as a PDF.

Mizuno conducts factory tours at its production sites, including the Yoro Plant and Senotech, to showcase its manufacturing expertise and on-site operations. In recognition of World Environment Day on June 5, Mizuno designates June as “Mizuno Environmental Month” and has been organizing cleanup activities around its domestic and overseas offices since 1997.
In fiscal year 2025, a total of 389 visitors from 33 companies and organizations participated in factory tours.

Mizuno Technics is engaged in risk communication through regular dialogue with stakeholders. This effort involves inviting local government officials and residents to actually tour the factory and explaining how the factory operates using various equipment, what products and waste are created, and what environmental conservation activities are being conducted. It's a proactive initiative where information is openly shared with community representatives, and their opinions and requests are actively solicited and incorporated into ongoing activities.

Mizuno conducts environmental workshops designed to foster environmental awareness among children through its manufacturing and environmental conservation activities. The workshops introduce the history of sports equipment and environmental initiatives implemented at Mizuno's manufacturing facilities. Participants engage in hands-on activities such as creating original keyholders from wooden bat offcuts and leftover baseball glove leather, as well as hand-stitching regulation baseballs.

The Mizuno Technics Yoro Factory manufactures baseball and golf products, which are Mizuno's core products and other sporting goods and the products made from composite material (carbon material). We installed solar panels on the roof of the factory's largest building, the golf manufacturing building, in January 2023. This will generate approximately 400,000 kWh of electricity per year, which will be used in the manufacturing processes of golf clubs, wooden baseball bats and other products.
We also installed emergency power supply equipment along with solar panels to ensure a stable power supply even in the event of a natural disaster. This emergency equipment not only serves the factory, but is also aimed at benefiting the local community by supplying power to neighboring areas in the event of an emergency.
