Message from the President of Tochigi Nitto Kohki

Tochigi Nitto Kohki began operation as a manufacturing factory of Nitto Kohki Co., Ltd. in 1977. The company demerged in 2000 to start business as current Tochigi Nitto Kohki Co., Ltd. Our key products are couplings, “CUPLA”, and pumps mainly with linear drive system and applied products, "MEDOMER". We also began production of “HHV CUPLA” used to supply and fuel compressed hydrogen, which is fuel for fuel-cell vehicles that has been attracting attention recently, for the first time in Japan. In 2013, we completed one of the group’s largest factory buildings, the seventh factory building, and added merchandise warehouse. By building our unique production lines that cover from material processing, inspection to shipping, we ensure that our manufacturing process is of the highest quality and reliability to meet our clients’ needs. Tochigi Nitto Kohki is committed to pursuing user- and eco-friendly manufacturing in compliance with the law with a spirit of challenge. We will work as one to keep growing. We appreciate your support.
