Company Profile

Founder, Yoshiaki Mitsui, Introduction

Born in Kumamoto Prefecture in 1921.

Passed away- July 10th, 2008.

Founder of MITSUI MFG. CO., LTD. currently Mitsui High-tec,Inc.

Continuously absorbed in the development of stamping tools and responsible for driving the transition from hand-finished technology to post-heat treatment and full-grinding finishing.

Recipient of the Japanese Emperor's Indigo Ribbon in 1984.

Time and time again, the leadership of Mitsui's tenaciously challenging spirit achieved industry paradigm shifts for technology of high precision tungsten carbide tools, IC leadframe stamping tools, MAC system (Mitsui Automatic Core assembly system), and spot electroplating production equipment. Also, aggressive erection of factories overseas contributed to early successes. In the short span of a single generation, Mitsui High-tec has become a truly global leading-edge technology corporation.

"Roads open up for those who travel a noble path" is the ideology. Not swayed by fashions of the time, employees are constantly asked, "What is the truth?" This simple spirit embodied by the Corporate Motto guides the corporation.
