Japan's wartime production of semi-automatic rifles was restricted to experimental and prototype models. Shortly before the war's end, the Imperial Navy produced the Type 5 rifle, a 7.7mm caliber copy of the American M1 Garand which featured a 10-round box magazine rather than the M1's 8-round en bloc clip. These were also manufactured in extremely limited numbers; perhaps as few as one hundred were produced. Limited resources and shortages of suitable arms caused some of the earlier prototypes to be committed to combat. The Japanese Garand can be found in Gallery 11, Ever Vigilant, at the NRA National Firearms Museum in Fairfax, Virginia.
