The Type 1 47mm AT gun was developed following the Japanese encounter with Russian armour and was the first indigenously developed dedicated anti-tank gun. It lacked the performance of other contemporary weapons of similar calibre; but was deemed sufficiently capable against lightly armoured tanks.

By the time it was introduced in 1942; it was therefore already outdated. The same gun was used as the main armament of the Type 97 Chi-Ha Shinhoto tank. It was also used by Japanese paratroops dropped disassembled in separate containers.
