Company history

In 1966 (Showa 41) Nagano Hiroshi, currently a consultant, with his younger brother, Nagano Shigeru, established the headquarters in Kanda, Chiyoda-ku, Tokyo and set up the Nagasaki branch office in Tsujimachi, Nagasaki city. After that both the headquarters and the branch office continued to develop reliable business, but because of variations in management and available services in 1968 (Showa 43) they split off the Nagasaki branch office as a separate independent company and transferred control as an opportunity to streamline management and expand business. Since then starting with Mitsubishi Heavy Industries, Ltd. Nagasaki Shipyards as well as other local major factories and suppliers we have continued to build up relationships of mutual trust which has led us to make steady progress to the current day. Also during this time a specialty factory for repairing and maintaining cutting tools was established as a service department. While keeping in mind to continuously improve the facilities and training of our high-skilled engineers, we received the high rating of (reliable Kowa) as a unique general trading company for our trading and both technical divisions.
