The Japanese Arisaka Type 99 rifle was a rugged bolt-action military rifle developed in the late 1930s as the Imperial Japanese Army’s primary service rifle during World War II. Chambered in the 7.7×58mm Japanese cartridge, commonly referred to as 7.7 Japanese ammo, the Type 99 was designed to deliver greater power, improved range, and reliable battlefield performance. Widely issued throughout the Pacific Theater and across Asia, the Arisaka Type 99 became known for its strong action, durability, and ability to function in harsh combat conditions. Today, rifles chambered in 7.7 Japanese remain popular among collectors and shooters seeking dependable 7.7 Japanese ammunition for historic military rifles.
