Shōwa Kōgaku, later renamed Leotax, was a Japanese camera maker.
It was founded in January 1938 by Nakagawa Kenzō (中川幹三) as Kyōei-sha (共栄社), based in Nippori (日暮里), Tokyo.[1] Nakagawa, a former engineer of Konishiroku, obtained financial support from Minagawa Shōten.[2] The company was renamed Gōshi-gaisha Shōwa Kōgaku (㈾昭和光学) at the end of 1938.[3] It made the Leotax rangefinder cameras until 1961, and it also made the Semi Leotax and Baby Leotax folders as well as the Gemflex subminiature TLR.
