The Tokyo Koku Ki-107 was a Japanese military training aircraft for the Imperial Japanese Army Air Force.
The Ki-107 was a wooden-built low-wing two-seat monoplane with an open cockpit.
Powered by a Hitachi Hatsukaze Ha-47 (Ha-11) inline piston engine it first flew in October 1943.
The Japanese Army had ordered 450 as primary trainers as replacement for the Kokusai Ki-86, but production was held up by air raids and only 29 had been delivered by the end of the war.
