Mars was a Japanese company which sold shutters and accessories in the late 1930s and early 1940s. It was based in Ebara, Tokyo (currently in Shinagawa).[1] According to the original documents found so far, its full name was Mars Shashin Kōgyō-sha (マース写真工業社),[2] but one recent source gives "Mars Kōgaku Kōgyō-sha" (マース光学工業社) instead, and the marking Mars Kogaku Tokyo appears on the shutter of the Baby Balnet camera.

The company made or sold various shutters, including the Lex (T, B, 1–200 or T, B, 5–200) and Patent Mars (T, B, 1–250).

A column in Asahi Camera April 1940 featuring the Mars shutter (T, B, 5–200, #00 size) says that the device was distributed by Mars Shashin Kōgyō-sha, but was actually manufactured by a company called Tōyō Seiki Kenkyūjo (東洋精器研究所), about which nothing else is known.[3]

In addition to its shutter range, the Mars company reportedly marketed an accessory called "Patent Goal Finder" (パテントゴールファインダー), combination of an eye-level and a waist-level finder.[4]
