In 1936, Kuwata released the Mulber (3×4) and Mulber Six cameras. Kuwata was certainly the owner of the "Mulber" brand, and the cameras were certainly made by third-party manufacturers. The name "Mulber Camera Works" appears on the shutter plate of the Mulber (3×4) camera and in original advertising documents, but that was certainly a dummy name, as other names ending in Camera Works.
In 1939, Kuwata released the Semi Mulber, a rebadged version of the Semi Kinka made by Yamamoto Shashinki Kōsakusho; the same camera was also sold by Riken as the Adler B. In 1940, it started distributing the Seica, a 4×4cm camera made by an unknown manufacturer, that was previously distributed by Riken. This might indicate that the company was involved into commercial agreements with Riken.
The Kuwata company used "KKS" initials in the name of various products, or applied a KKS marking. The significance of these initials is unknown.
Kuwata Shōkai survived the war, and it was an authorized dealer of the Shinkoh Rabbit in 1953.
