Ōfuna Kōgaku-Kikai Seisakusho (大船光学機械製作所) was a Japanese camera maker, which also used the English name Ofuna Optical Instrument Manufacturing Co., Ltd.[1] It marketed a total of four cameras after the second world war.

History

The company originated during the war, when it started as a factory of Tomioka in Kamakura (the historic city, now effectively a distant southern suburb of Tokyo).[2] The factory was precisely located in the town of Dai, immediately to the north of the main city, in a zone which is commonly known as Ōfuna, hence the name of the company.[3] The factory produced binoculars and other military optics.[4] Tomioka's main factory (in Yukigaya-Ōtsuka, Tokyo) was destroyed by bombing toward the end of the war, and when the war ended Tomioka moved to a western outer suburb of Tokyo. Its Kamakura factory, which had escaped unscathed, raised capital independently and became a separate company.[5]

The newly independent Ōfuna company tried to diversify its activities to various civilian products.[6] It made the Herlight 4×4cm box camera from 1947, and at least one Herlight prototype was made for 24×36mm pictures on 35mm film. This first attempt to enter the camera market was not a success, and the company continued the production of binoculars, making a number of them for the US occupation army.[7]

Some years later, the distributor Kashimura Yōkō, which was already distributing the Ōfuna binoculars, solicited the company to make a line of cameras.[8] These would be the Ofunaflex TLR and the Ofuna Six folder, released in 1953. These cameras sold poorly, and their production was stopped around 1955. At the time, other Ōfuna products included binoculars, opera glasses, enlarging lenses and military products.[9]

The company's last incursion on the camera market was the coupled-rangefinder Ofuna Six, actually a rebadged Mine Six by Takane, ordered by Kashimura for export. The Ōfuna company continued the production of binoculars, then closed its doors in 1963.[10]
