Fuji Kōgaku

Fuji Kogaku was a Japanese camera maker before the war. Its full name was Fuji Kōgaku Kōgyō K.K. (富士光学工業株式会社, Fuji Optical Industries Co Ltd). It seems that it was related to the other well known Fuji company. Various Japanese websites (see here, here and here) say that the company became Taisei Koki after the war.

The company logo was FUJI KŌGAKU written in a cemented doublet lens scheme (a type of logo used by many other optical companies). There was a protuberance on top of the logo, maybe an allusion to the Mount Fuji. The same type of logo was later used by Taisei Koki. The short name used by the company in some ads was 富士光 (Fujikō).
