The skill of engineers has been essential to the economic growth of Japan. Many engineers are educated in a department of engineering, and the existence of Technical Colleges is important. Japanese manufacturing companies think more highly of Technical College graduates than university students, but Technical College graduates do not have a degree. This paper describes the expectations to Technical Colleges from Japanese manufacturers, and the contradiction of the Japanese educational system. The present author proposes a method for growth of Japanese economy, where Technical Colleges are authorized formally as a university.
