The Arisaka rifle (有坂銃 Arisaka-jū) is a family of Japanese military bolt-action service rifles, in production and use since approximately 1897, when it replaced the Murata rifle (村田銃 Murata-jū) family, until the end of World War II in 1945. The most common specimens include the Type 38 chambered for the 6.5×50mmSR Type 38 cartridge, and the Type 99 chambered for the 7.7×58mm Type 99 cartridge, which is comparable in power to a modern .308 Winchester round. Many thousands of Type 99s and other Arisaka variants were brought to the United States by soldiers as war trophies during and after World War II.
