Corporate Philosophy of Mitsuboshi Belting:

To give attentive consideration
to both humanity and nature

In 1999, when terms such as “ESG” and
“sustainability” were not yet common,
Mitsuboshi Belting established this corporate
philosophy as the cornerstone of the company.

Now that the role that companies should play
for the environment and society has become
more important, we will reconsider the role
that Mitsuboshi Belting should play and the
significance of its existence based on this
corporate philosophy, and strive to contribute
to society and improve our engagement with all
of our stakeholders.

Philosophy System of Mitsuboshi Belting



Keeping in mind what kind of value the Mitsuboshi Belting Group should provide in society as the role of companies for the environment and society has now become more significant, and what is the “unique identity of our company” that we should be proud of, the Group will share these values with all stakeholders and aim to be a company that “chooses and is chosen by” them for 100 years to come.


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.

Target position

A company that supports people's comfortable lives with the power of science

You may not often see Mitsuboshi Belting's products directly. However, our products continue to quietly play a role in our daily lives, such as in cars, motorcycles, printers and other office equipment, ATMs, cash registers, and various home appliances including washing machines and bread machines.

The Mitsuboshi Belting Group aims to be a company that continues to support people's comfortable lives by creating innovation through our efforts to deepen the power of science and valuing the challenging spirit.



Our promise: the basis of our actions

Motto: 
To act with pride in how we stand today and look forward to the future.

Mitsuboshi Belting believes that it is the source of the realization of the growth of individual employees and the sustainability of the company for our employees “to act with pride in how we stand today and look forward to the future.”



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.
