Tanaka Kōgaku (田中光学, meaning Tanaka Optical) was a Japanese camera and lens maker.
Tanaka Kōgaku K.K. (田中光学㈱) was initially based in Kawasaki, Kanagawa (a distant suburb of Tokyo). The company started to work on a Leica copy called Tanack 35 in 1952, and released the camera in 1953. It was designed by a former employee of Kōgaku Seiki (predecessor of Nicca), who worked under Kumagai Genji on the Nippon Leica copy. It is not known if this was the company's first product, or if it was already making screw lenses or camera accessories.
In 1954, the company installed its headquarters in Ginza, perhaps to carry out the distribution of the Tanack itself, whereas the factory remained in Kawasaki. The camera was improved the same year as the Tanack IIIS and in 1955 as the Tanack IV-S. The latter model met some success and was produced until 1958. At the same time, Tanaka was making a series of Tanar lenses in Leica mount, to equip the Tanack cameras.
From 1956 onwards, the cameras were advertised by Tanack Camera K.K. (タナックカメラ㈱), new name of the Ginza commercial branch. Documents dated 1956 show the company name "Tanaka Kōgaku Kōgyō K.K." (田中光学工業㈱, meaning Tanaka Optical Industries), but they might be mistaken, and later ones have "Tanaka Kōgaku K.K." (田中光学㈱) again.
In early 1959, the company released the Tanack V3 in an attempt to give a successor to the Tanack IV-S. The camera had a specific bayonet mount, but was only sold with Leica screw mount lenses fitted via an adaptor. Tanaka finally developed the Tanack VP, an evolution of the V3 turning back to the Leica screw mount, but it lacked the resource and time to release the camera before its failure in December 1959, though it seems that a few cameras were assembled and reached the market after that date.
