Ho-203 was a Japanese autocannon that saw considerable use during World War II. It was a long-recoil automation of the Year 11 Type direct-fire infantry gun. It was fed by a 15-round closed-loop ammunition belt. It was operationally used only as the nose gun of the Kawasaki Ki-45-KAI heavy fighter, the anti-bomber workhorse of the Imperial Japanese Army, and tried out in the upper fuselage of the III-KAI variant of the Mitsubishi Ki-46 Dinah twin-engined warplane as a Japanese form of the Nazi Luftwaffe's Schräge Musik upwards-aimed armament system for heavy fighters.

L'Ho-203 era un cannone aeronautico automatico Giapponese che vide un uso considerevole durante la Seconda guerra mondiale. Funzionava con un meccanismo di lungo rinculo (per cui la sua cadenza di tiro è relativamente basso in confronto ad altri cannoni dello stesso calibro, per esempio l'Ho-204) ed era dotato di un caricatore a nastro con 15 colpi. Fu montato sul muso del Ki-45, il caccia pesante antibombardiere dell'aviazione militare giapponese, e nella versione III-KAI del Ki-46 come cannone dorsale con orientazione frontale, analogamente al "Schräge Musik" adottato su alcuni caccia pesanti della Luftwaffe.
