～Company Profile～
Infinitive belts creating future infinity

Belts that transmit power. This is the origin of Mitsuboshi belts.
Throughout the Japanese industrial development, Mitsuboshi belts have been continuously running powering industries into the future. We have been expanding our expertise into various areas of today's diverse needs, from daily products manufacturing to industrial machine components and ambitious land and artificial reservoir projects.

Mitsuboshi Belting has achieved numerous milestones. In this day and age, we ask ourselves what is really critical for people living in this era. What must we strive to create now for a better tomorrow. It is with this firm belief that we passionately produce belts for the new age and the good of mankind. Belts embracing infinite possibilities. We want to touch human hearts.

Mitsuboshi Belting Ltd. was established in 1919 as a manufacturer of industrial belts and through untiring efforts, has become one of the leading companies in the belt industry.

Now our products include waterproofing sheets and engineering plastics, but we have always adhered to the motto, "produce quality and sell quality" and to earn the trust of customers. Mitsuboshi's high-quality products are essential to daily life as well as progress of the industry.

We have always maintained strict quality assurance and both domestic and overseas factories are obtaining ISO 9001 or ISO/TS 16949, which is considered to be the most stringent international standard for quality management systems. Our main domestic factories and several other overseas factories have been certified by ISO14001, and we are actively engaged in development of environmentally-friendly products.

With the basic management policy, "to contribute to society by supplying goods of high performance, high precision and high quality" and the corporate philosophy, "to give attentive consideration to both humanity and nature", we strive for the prosperous future of the society.
