The Hino–Komuro M1908 was a blow-forward operated, semi-automatic pistol of Japanese origin and was patented by Yujiro Komuro.
Most of the records were lost when Hino's home in Tokyo was fire bombed during World War II.
The 8mm chambering was later dropped, as the cartridge proved too powerful for the design.
In December 1992, a cache of 17 Hino–Komuro Pistols chambered in .32 ACP were found in a warehouse that are believed to have been stored for 45 years and seven were retained by Japanese authorities for evaluation when the rest were scheduled for destruction as they were not legally registered.
As there are only a small number of these weapons, they are considered highly collectible firearms.
