Published: May 26, 2025 | Updated: February 17, 2026
The Type 100 was Japan’s only mass-produced submachine gun of WWII, offering select-fire capability and a relatively mild 8mm cartridge.
Curious about how much your Type 100 sub machine gun is worth? Whether you’re looking to sell or simply understand current pricing, we’ll help you assess the market value of your firearm.
The Type 100 submachine gun was introduced late in World War II and is notable as the only Japanese SMG produced in meaningful numbers. Chambered in 8×22mm Nambu and built with a distinctive top-folding bayonet, it was issued primarily to paratroopers and special forces. Surviving transferable examples are exceedingly rare and command high values among collectors.
