Creative development ideas, combined with production technology which gives a high-precision and high-performance shape to these ideas, meet the needs of an expanding market by providing a stable supply of products. The Ujiie, Yamagata and Shirakawa plants, which make up Nitto Kohki group's production base, are uniquely organised with unified automated production lines that begin with the processing of raw materials and end with the inspection of finished products. We have established a production system that promises a stable supply of high-quality, high-performance products.

In order to pursue thorough product quality control, we take measurements and analyse data from test cases that go beyond the realm of possibility. These include rigorous continuous operation tests and checks of basic performance under various working conditions. With this exacting quality control system, Nitto Kohki group will always supply the market with products of superior quality. In every part of the world, in every working environment, our adherence to quality--performance at 100 percent of expectations--has provided us a large reservoir of trust as the top name in the business.

In October 1956, Toshio Mikiya (current honorary chairman), founded Nitto Kohki to manufacture and market the Air Micrometer, a device which measures sizes in units of 0.1 microns.

The company also began development of high-performance fluid couplings, which were marketed under the Cupla brand name. Today, Nitto Kohki's product line numbers over 20,000 different Cupla products that are now recognized throughout the world.

Recognizing that there was a potentially massive demand for a portable drill press, Mikiya next developed the Atra portable drill press, which incorporates an electromagnet that holds the device in place.

The Atra drill press, having undergone continuous updates and improvements over the years, still holds its seat as one of our most popular products.

Toshio Mikiya
Founder


Our founder strove toward the goal of producing energy- and labour-saving technology, developing industrial tools that could be operated with equal ease by a novice or an experienced worker. At the time, Japan had an abundant work force and factories could easily find skilled workers for any operation. However, he realised that someday we would face high wages and labour shortages. In these convictions was born his long-term goal of developing energy- and labor-saving technology.

Today, Mikiya's predictions have become a reality. Worldwide, energy- and labour-saving are the watchwords. Armed with core technologies of fluid control engineering and mechanical engineering, Nitto Kohki continues to develop new products that correspond to market demand. We are currently introducing many unique products in diverse fields such as quick-connecting fluid couplings, machine tools, Linear and Diaphragm pumps, robots and balancers.
