Mars was a Japanese company making shutters and accessories in the late 1930s and early 1940s. It was based in Ebara, Tokyo (currently in Shinagawa).[1] Its full name was either "Mars Kōgaku Kōgyō-sha" (マース光学工業社) or "Mars Shashin Kōgyō-sha" (マース写真工業社).[2]

The company made various shutters, including the Lex (T, B, 1–200 or T, B, 5–200) and Patent Mars (T, B, 1–250). It reportedly made 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.[3]
