History

The Imperial Japanese Army first issued their requirement for an anti-tank rifle in 1935 due to tension with the Red Army over the Manchurian Border and the Republic of China purchasing Vickers Six-Ton tanks. Kokura Arsenal entered a 20x125 mm design for the competition in 1936 which competed against a design from Nagoya Arsenal based on the Hotchkiss Mle 1929 and was accepted into service in 1938 as the Type 97 Automatic Cannon.

Despite the name, Type 97 was a semi-automatic only rifle that was the heaviest anti-tank rifle of World War II. While it saw some action in the 1938 Battles of Khalkhin Gol against the Soviets and was used for infantry support in China (leading to the development of a new high explosive round), it was obsolete by 1942 due to stronger tank armour.

The Imperial Japanese Army Air Service used the Type 97 in two capacities. The first was as a weapon for the Teishin Shudan Paratroopers. The second capacity was the Ho-1 and Ho-3 aircraft-mounted automatic cannons. Unlike the Type 97, the Ho-1 had a fully automatic mode with a rate of fire of 300-400 rpm and was fed with a larger 15-round detachable box magazine compared to the 12-round magazine used on the Type 97. The Ho-1 served as the defensive armament for the Ki-49 heavy bombers.
