Mori Seisakusho (森製作所, meaning Mori Works) was a Japanese camera active from the mid or late 1930s. It was based in Kamihirai (Tokyo) during World War II. Various cameras are attributed to this company, but little is known for sure.
In the mid-1930s, Mori reportedly made the Semi Dymos 4.5×6cm folder. From 1938, it made the Rollekonter 6×6 TLR. Rebadged versions of the camera were sold by various other companies. The Semi Konter and Konter Six, about which little is known, were perhaps made by Mori Seisakusho as well. An original document says that the Zessan sold by Riken was produced by "Mori Kōjō" (森工場, meaning Mori Plant); it is likely that this was another name for Mori Seisakusho.
After World War II, Mori Seisakusho released the Bikor-Flex, a revised version of the Rollekonter. It was one of the first Japanese TLR cameras available on the market. It is also said that the company made three prototypes of a Morrisflex 6×6 TLR.
Mori was probably absorbed into Bikōdō, distributor of the Bikor-Flex. In late 1949, the company Bikōdō Seisakusho (meaning Bikōdō Works) released a Superflex 6×6cm TLR, again based on the Rollekonter, continuation of Mori's former camera line.
