It was the Imperial Japanese Army Air Service's (IJAAS) first all-metal enclosed cockpit aircraft with retractable landing gear.
Development began in December 1937, headed by the aeronautical engineer Hideo Itokawa, as a successor to the preceding Nakajima Ki-27 monoplane fighter. Twelve months later, the first prototype was completed, performing its maiden flight in January 1939. While satisfying the performance requirements of the IJAAS, test pilots expressed dissatisfaction over the limited improvements over the Ki-27. In response, Nakajima enacted a weight reduction programme, slimmed the fuselage, redesigned both the tail unit and canopy, and adopted Fowler flaps (which improved performance during tight turns).
