ABOUT US

I hope our products contribute to the safety, security, and convenience of everyone and of society.

Our company was established in 1953. We started out business making spiral and constant force springs for wall clocks and alarm clocks. In the period of rapid economic growth (around the 1960s), we began to manufacture spiral springs and constant force springs for various household items such as time switches for washing machines and toaster ovens, winding cords for vacuum cleaners, and lifting devices for fans.
Nowadays, we mainly manufacture spiral springs for automobile seatbelt retractors, of which we have the top share in Japan.
In this way, our spiral springs silently support the safety and convenience of everyone´s daily life.
We have developed in-house machines to manufacture spiral springs and a proprietary simulator that makes full use of mechanics and material engineering.
We have bases in China, Indonesia, and in Mexico. In order to meet a wide variety of demands apart from high quality, low price, and short time delivery, we also strive not to stop improving technology and developing new capabilities.
