Teikoku Shashin Kōgaku Kōgyōsha
Teikoku Shashin Kōgaku Kōgyōsha (帝国写真光学工業社, meaning "Imperial Photographic and Optical Industrial Company") was a Japanese company active in 1944. Its name appears on some advertisements for the Bolex, where it is mentioned as the distributor of the camera. The address was Asakusa-ku Kikuyamachi 2–3 in Tokyo (東京都浅草区菊屋町二ノ三). It was perhaps the successor of Nittō Shashin Kōgaku Kōgyōsha, the manufacturer of the Bolex in 1940.
