Company Profile
Message from the President
We started in 1953 with a small town factory that undertakes the assembly of watches. As a cooperating factory of the world watch "SEIKO", we have inherited production + technology and have grown into a company responsible for parts production, mold manufacturing, and stamping. With the proficiency of the watch industry and the transfer to overseas, our business has decided to steer from watches to de-clocking and to develop fine stamping technology for information equipment parts. Since then, the business of information equipment has shrunk due to the overseas production of customers, and due to repeated dangers, the business has been converted to the automobile industry.
Today, the automobile industry is said to be in an era of major transformation of once every 100 years, and our business is also under pressure for further business transformation. However, our microfabrication technology has high expectations in various industries.
We have overcome the crises we have faced many times with our high technology, advanced management, and the human power to support them. We aim to be a company that is useful to the local community and the world with the technology and diverse human resources that have been passed down for 70 years.
