The Hamada Type Automatic handguns were semi-automatic pistols developed starting in 1941 for use by the Empire of Japan during World War II. Developed by Bunji Hamada, the pistol took its basic design from the Model 1910 Browning. They were produced by the Japanese Firearms Manufacturing Company, as opposed to a state arsenal. Two variants were produced: Type I, chambered in .32 ACP like the Model 1910, and Type II, chambered in 8×22mm Nambu, the standard pistol cartridge of the Japanese military.
