The Mitsubishi L4M1 was the designation given to a small number of Mitsubishi Ki-57-I transport aircraft that were transferred to the Imperial Japanese Navy. They were also known as the Navy Type 0 Transport Model 11. The L4M1 was based on the Ki-21 twin-engined heavy bomber, sharing the same wings, engines and cockpit as the bomber version, but with a new main fuselage and the wings moved down from the middle of the fuselage to the base.
