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.
