About Us
Management Message
Our company has a history of more than 100 years since its establishment in 1919, and while maintaining a passion for "manufacturing" that has been passed down continuously, while valuing the strong belief as a manufacturer, we support the lives of everyone. We have contributed to society through the provision.
The socio-economic situation has been unstable in recent years, and in addition, the industrial structure such as the automobile industry has entered a new phase. As the business environment surrounding our company is changing from moment to moment, we believe that excellent foresight that accurately grasps the movements of the times such as people's way of thinking, lifestyle changes, and trends will be an important basis for us.
In the future, we will be required to make further innovations in business operations and technological development, but our Group employees will work together to move forward step by step. Face the reality while looking ahead to the next 100 years, and embody sustainable growth and transformation through business activities to solve social issues based on the basic philosophy of "To give attentive consideration to both humanity and nature." We aim to develop into a prosperous future.

Our Values
Corporate Philosophy:
To give attentive consideration to both humanity and nature
In 1999, when terms such as “ESG” and “sustainability” were not yet common, our corporate philosophy of “To give attentive consideration to both humanity and nature” was established as the cornerstone of the company. The concept of “to give consideration to humanity” represents our desire to be an organization that respects the human rights, personality, and individuality of all people involved in our business activities and in which each and every employee can fully exert his/her originality, and “to give consideration to nature” represents our desire to protect the environment, including climate, water, and biodiversity, of this planet on which we live to realize a sustainable society. Our corporate philosophy of “To give attentive consideration to both humanity and nature” is our important and unchanging value in order for us to be a company that will continuously contribute to society in a sustainable way for the next 100 years.
Mission to be Fulfilled
Management Principle:
To contribute to society by supplying goods of high performance, high precision and high quality
“To make products with sincerity” —This was one of our management principles at the time of the foundation of our company in 1919. Based on this belief, we have faithfully engaged in “manufacturing” under the spirit of “manufacturing quality and selling quality” for more than 100 years since our foundation.
Mitsuboshi Belting aims to achieve a “trade-on” between economic value and environmental/social value and contribute to solving social issues, including the realization of a decarbonized society, by providing our products such as next-generation belts with a higher proportion of non-petroleum-derived raw materials and high-performance timing belts used in wind power generators.

Revision of the Mitsuboshi Belting Group Code of Conduct
In the current age known as the VUCA world, Mitsuboshi Belting considers that while some values should be cherished as a company without change, there are also many things that need to be changed in order to adapt to the rapidly changing social situation and environment.
In November 2022, we made major revisions to our previous Code of Conduct in consideration of the ten principles of the United Nations Global Compact and other factors to ensure that it is compatible even with today’s society, in which companies are expected to play a greater role. This revised Code of Conduct is positioned as “our promise” for all Group employees in order for our company to continue “to give attentive consideration to both humanity and nature.”
This Code of Conduct has been translated into a total of five languages, including English and Chinese, and has been disseminated to all employees of the Mitsuboshi Belting Group. Also, with the aim of ensuring that each employee correctly understands this Code of Conduct, meetings are also held at each department to read it.
