The company was founded by Toshio Mikiya in 1956 as a manufacturing and sales company of Air Micrometer and Quick Connect Couplings in Tokyo, Japan. Over the 60 years of business, the company has expanded its business field but has always remained focused on manufacturing quality products, with a philosophy that emphasizes trust, reliance, and high quality. We design and manufacture high quality products based on the core technologies of fluid mechanics, precision engineering and more recently, electronic engineering.

We hope to contribute to society by focusing on the development of products that meet the needs of the age and manufacturing technologies that are honest and genuine.
