The Type 4 Rifle, often referred to as the Type 5 Rifle, (Japanese: 四式自動小銃 Yon-shiki jidousyoujyuu) was a Japanese experimental semi-automatic rifle. It was a copy of the American M1 Garand but with an integral 10-round magazine and chambered for the Japanese 7.7×58mm Arisaka cartridge. Where the Garand used an en-bloc clip, the Type 4's integral magazine was charged with two 5-round stripper clips and the rifle also used Japanese style tangent sights. The Type 4 had been developed alongside several other experimental semi-automatic rifles. However, none of the rifles entered into service before the end of World War II, with only 250 being made and many others were never assembled. There were several problems with jamming and feed systems, which also delayed its testing.
During the Second World War, Japanese soldiers relied on high-quality bolt-action type rifles. However, guns were getting scarce and the enemy (Americans and British) had replaced their weapons with modern repeat-fire rifles. Germans and Russians were also developing their own prototypes which would give them great advantage on the battlefield. This pressured Japan to find a quick way to cope with their military disadvantage. Instead of designing and investing in a new weapon from scratch, they opted to copy the American M1 Garand.
Japan had previously developed semi-automatic service rifles but none of them has been viewed as successful or of trustworthy quality. The design work for the Type 4 began in 1944. The rifle was meant to be mass-produced in 1945. Unfortunately, the Japanese defeat in the war in August halted its manufacturing. At the time, only 100 guns were completed out of the 250 in the workshop. Twenty of them were taken by the Allies at the Yokosuka Naval Arsenal on Honshu after the end of the war.
Today, the Japanese Garand is a rarity. An example of this rifle can be found in the US National Firearms Museum, in the World War II section.
