A pretty neat little article on the Japanese attempt to recreate the M1 Garand
By the beginning of 1944, Japan’s situation in the Pacific became more dire as the U.S. pushed closer to the home islands. Japanese designers turned their attention to copying the M1 Garand. At first the Japanese experimented with the M1 Garand rechambered to their 7.7x58mm cartridge, which is dimensionally similar to .30-06.
They found that the M1 could fire the 7.7mm, but encountered feeding issues as a result of the en-bloc clip feeding system. As a result, the en-bloc clip was deleted from their design in favor of a 10-round internal magazine fed by two Arisaka five round stripper clips. This new Japanese adaptation of the M1 was called the Type 4 rifle, but also known as the Type 5, and manufacturing shops for it were set up at the Yokosuka Naval Arsenal in Tokyo Bay.
The Type 4 was intended for mass production by 1945. Some 250 parts sets for these rifles had been produced with little more than 100 rifles completed by the time that Japan surrendered in September 1945. After the war, Allied personal discovered the parts and assembled rifles at Yokosuka Naval Arsenal.
Twenty of these rifles were taken for study or as trophies, with few making their way into the United States and fewer still on display to the public today. Little is known about the performance of the Type 4 other than reported reliability issues — there were no known cases of the rifles being used in combat. Internally and externally, the Type 4 is very similar to the M1 from which it was copied.
