The history of TAMAGAWA SEIKI CO., LTD. can be traced back to March 1938, when the company's founder, Hiroichi Hagimoto, established the company near the Tamagawa River in the south of Tokyo. In 1942, he set up the Iida plant in his hometown, Iida city of Nagano prefecture, to contribute to regional industrialization.

After World War II, we immediately started to develop, produce and sale instrument motors anticipating diverse needs of the age. The business was expanded to automatic control equipments and aerospace instruments with the motto "grow technology and sale technology". The technology is symbolized by our registered trademarks, "MOTORTRONICS", "SPACETRONICS", "Smartcoder" etc.

Tamagawa Seiki continues research and development of three base technologies, the Synchro which detect the angle with high accuracy (2 dimensions), the Gyroscope which is necessary for three dimensional controls and the analog/digital convertor (Smartcoder). We have been working, since the foundation, to improve the accuracy of our angle sensors by just a factor of ten per decade.

We are determined to continually train the strength of product development and sales forces, to flexibly meet customer's requests by our product quality and performance and to grow up as a "Glocal (Global + Local ) Company" which can supply the only /number one products. Your continued patronage and support would be highly appreciated.
