The Type I Carcano rifle was produced by Italy for the Japanese Empire prior to World War II. After the invasion of China, all Arisaka production was required for use of the Imperial Army, so the Imperial Navy contracted with Italy for this weapon in 1937. The Type I is based on the Type 38 rifle and uses a Carcano action, but retains the Arisaka/Mauser type 5-round box magazine. The Type I was used primarily by Japanese Imperial Naval Forces and was chambered for the Japanese 6.5×50mm Arisaka cartridge. Approximately 60,000 Type I rifles were produced by Italian arsenals for Japan.
