Endate and K. Watanabe at Kitami. Koichi Nishimura (b. 1943) is the chairman of the telescope manufacturing company that bears his name. Nishimura began manufacturing reflecting telescopes in 1926. Since then, their telescopes,have been installed in science museums and astronomical observatories throughout Japan.
