G.K. Yamamoto Shashinki-ten (合名会社山本写真機店, meaning Yamamoto Camera Shop) was a Japanese distributor in the 1930s, based in Osaka, perhaps with a subsidiary in Tokyo.[1] It distributed a number of cameras and accessories called Weha, and was certainly the owner of the Weha brand.

See also Yamamoto Shashinki Kōsakusho, a camera maker based in Tokyo which is probably not related.
