Since the Company’s establishment, research and testing were conducted at manufacturing sites but more robust development of technology was needed in the face of international competition after the war.
The opening of a research laboratory was announced as part of the 30 th anniversary events and a testing factory in Amagasaki was purchased from Sumitomo Electric Industries. Under the leadership of Tomoyoshi Takahara, director, the factory was modified into a research lab in November 1949. Over the next 20 years, the research lab played an important role in supporting the Company’s technological breakthroughs.
