The Mitsubishi Shūsui (秋水, Sharp Sword), naval-designation J8M, army-designation Ki-200, 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.

The name Shūsui literally translates to "Autumn Water", but is used as a poetic term meaning "Sharp Sword" deriving from the swishing sound of a sword.
