The Ki-54 was developed in response to an Imperial Japanese Army requirement for a twin-engine advanced trainer, principally for crew training. The prototype first flew in summer 1940 and, on completing trials, entered production in 1941 as Army Type 1 Advanced Trainer Model A (Ki-54a). The Ki-54a was soon followed by the Ki-54b as Army Type 1 Operations Trainer Model B and Ki-54c as Army Type 1 Transport Model C. The Ki-54b and -c enjoyed successful careers until the end of the war. A few captured aircraft were flown after the war by various users.
