The Mitsubishi J8M Shūsui is a Japanese World War II rocket-powered interceptor aircraft closely based on the German Messerschmitt Me 163 Komet. Built as a joint project for both the Navy and the Army Air Services, it was designated J8M (Navy) and Ki-200 (Army).

The Mizuno Shinryū/Jinryū was a late-World War II Japanese rocket-powered interceptor. While the Jinryū was still in development, Mizuno began to develop an interceptor which both the Army and Navy air force were in desperate need of to fend off the Boeing B-29 Superfortress. When Japan surrendered to the Allies on 15 August 1945, all aircraft that were under development were stopped, including the Jinryū & Shinryū II. The Shinryū II was the second aircraft developed in Japan to use a canard design, after the Kyushu J7W Shinden.
