Nittō Shashin Kōgaku Kōgyōsha (日東写真光学工業社, meaning "Japanese Photographic and Optical Industrial Company") was a Japanese company active in 1940. Its name appears on an advertisement for the Bolex, where it is mentioned as the maker of the camera. The address was in Tokyo, Kyōbashi. It was perhaps succeeded by Teikoku Shashin Kōgaku Kōgyōsha, known as the distributor of the Bolex in 1944.
