Arisaka (有坂銃 Arisaka-jū) is a family of Japanese military bolt-action rifles, in production from approximately 1898, when it replaced the Murata rifle, until the end of World War II in 1945. The most common specimens include the Type 38 rifle chambered in the 6.5x50mm Arisaka cartridge, and the Type 99 rifle chambered in the 7.7x58mm Japanese cartridge. Many thousands of Type 99s were brought to the United States by GIs during and after World War II.
