The Japanese Type 100 SMG, particularly the simplified 1944 'Late Pattern', was a rare weapon with an estimated 8,000 units produced. Its design incorporated a unique compensator, a side-mounted 30-round magazine, and a bayonet lug, reflecting Japanese martial culture. The 1944 pattern increased the rate of fire to 800 rpm from the 1940 pattern's 450 rpm.
This visual tour provides an in-depth look at the Japanese Type 100 SMG, highlighting its late-war construction features. Key details include the side-mounted magazine, perforated barrel shroud, bayonet lug, and simplified sights. The video emphasizes the welding and machining marks indicative of its production period and showcases the 8mm Nambu caliber and 30-round magazine.
The Japanese Type 100 SMG, developed late in WWII, was a rare firearm chambered in 8mm Nambu. It featured an open-bolt, blowback action and came in standard and paratrooper variants, the latter with a folding stock. Notable features included a bipod, chrome-lined barrel, and bayonet lug, though its 30-round magazine was prone to snagging. The 1944 model saw simplification and a higher rate of fire.
This video provides a book review of William Easterly's "A Comprehensive Study of Japanese Submachine Guns: 1920-1945". The reviewer highlights the scarcity of information on this topic and praises Easterly's work for its inclusion of photos, data, and descriptions of numerous experimental Japanese submachine guns from the interwar period, as well as the officially adopted Type 100 models. Despite its high price and production quality, the reviewer considers it an invaluable resource for those interested in this niche area of firearms history. Purchase information for the 65-page booklet, including contact details for the author, is provided.
