The Type 97 automatic cannon (九七式自動砲, Kyū-nana-shiki-jidōhō) is a 20-millimeter (0.79 in) Japanese anti-tank rifle that began development in the 1930s. It was used by the Imperial Japanese Army (IJA) during the Second Sino-Japanese War, the Soviet–Japanese border conflicts and the Pacific War. Improvements in armour thicknesses on tanks rendered the Type 97 obsolete by about 1942. This weapon was not related to the Type 97 heavy tank machine gun used in armored vehicles or the Type 97 aircraft machine gun used in Japanese Navy aircraft.
