The Kyōfū was produced as a floatplane fighter in limited numbers. Production examples dispensed with the counter-rotating propellers of the prototype and the pilots learned to deal with the engine torque on take-off. The Kyōfū served operationally in Balilpapan, Borneo, and finished the war on Lake Biwa defending the Tokyo area. This is the Hasegawa kit built as an example from the Sasebo Kōkūtai. It is fitted with a more conventional engine arrangement and features individual exhaust stacks with a standard propeller spinner.
