Yamamoto Shashinki Kōsakusho
Yamamoto was a Japanese company making or selling cameras before World War II. It sold the Semi Kinka, a 4.5×6 folder, copy of the Nettar.
Maybe it was the same company as the distributor Yamamoto Shashinki-ten (山本写真機店, meaning Yamamoto Camera Shop), which sold a 6.5×9 folding plate camera called Weha Light around 1930, the Weha Chrome Six from 1937 and was an authorized dealer of the Wester or Semi Wester 4.5×6 folder by Nishida.
