Toa Koki’s Business Activities
-
World-class products
The first small Toa Koki Factory was founded in the former castle town of Kashima City, Saga Prefecture during World War II. The company overcame the hardships of war and the subsequent economic turmoil and finally established itself as a manufacturer of ship components that was able to provide support to the shipping industry both in Japan and overseas. One of its major products is large cylinder liners for diesel engines, which enjoy the largest share of the global market.

Sophisticated technology
The main parts of diesel engine components are made of high-quality cast metal that demands the highest quality and precision. Thus, the manufacture of these products requires sophisticated technology and skill as well as quality management systems such as ISO 9001. The following is a description of some of the technological skills we have developed over the years.
