The J7W1 was designed as a high speed interceptor fighter with great firepower and high climb rate to intercept the B-29 Superfortresses.
First, the canard concept was tested with three MXY6 gliders, then a designing team with captain Masaoki Tsuruno (Imperial Japanese Navy)
developed the J7W1. Two prototypes were built, the first had its first flight on august, 3rd 1945. The second was never tested.
It was an all-metal construction with a full retractable landing gear and a six-blade-propeller. Quantity production was undertaken,
but no production aircraft had been completed due to end of the war.
The J7W2 version was planned to get a 900kp Ne-130 axial turbojet instead of the radial powerplant.
Two J71W prototypes were completed in the spring of 1945 at the Zasshonokuma plant of Kyushu Hikoki K.K.
