The Type 100
Designed and built by the Nambu Arms Manufacturing Company under a low-priority military contract, the Type 100 was a submachine gun that was first delivered to the Imperial Army in 1942. Japan was surprisingly late to introduce the sub-machine gun to its armed forces — a few models of the SIG Bergmann 1920 (a licensed version of the German MP 18) were purchased from Switzerland in the 1920s. These were examined and copied, with significant changes. In 1942 the Type 100 SMG was first delivered for service, used by Japanese marines during the invasion of Southern China.

It is based on a simplified Bergmann MP18, modified for the 8mm Nambu round. It was an automatic-only, air-cooled, blowback weapon firing from an open bolt and feeding from a side-mounted, 30-round detachable box magazine. The barrel was given six-groove, right-hand-twist rifling. Unusually for a submachine gun (but typical of Japanese weapons of the era), a bayonet lug was fixed under the barrel, in this case with a heavy bar and lug. Some of these models featured a bipod, and others featured a complicated muzzle brake.The Type 100 had a chrome-plated bore to help fight corrosion in Asian jungle conditions. Its complex ammunition feed included a feature whereby the firing pin would not operate until the round was fully chambered; frequent stoppages in firing were experienced in the field. The round was the underpowered and relatively ineffective 8 mm pistol round. The curved box magazine extending from the left side made for poor weapon balance when full. The sights were canted to the left.
