Kawanaka Group

The Japanese automobile industry continues to change drastically and demonstrate its presence even in an era of global competition. Roughly 30,000 parts are necessary to make one car, and at the heart of these parts is high precision technology. That is to say, cars are the fruit of the Japanese manufacturing spirit and technology.
This is the company profile of the Kawanaka Group, which plays this crucial role in its work alongside the Japanese automobile industry.
