Kyushu J7W Shinden, (Scanned from René J. Francillion "Japanese Aircraft of the Pacific War" - Putnam - 1979),
got from the Imperial Japanese Navy Page

Usually, japanese fighters were small and agile fighters with an extremely long range and no armor.
Since the B-29 Superfortresses began their bombing runs, the necessity for a specialized
interceptor fighter was obvious. Especially great firepower, high climb rate and high speed were essential.
The J7W1 was intended to be such an interceptor fighter.
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.

My comment:
Even if it appeared in early 1944, it would have been without any chance against the
huge bombing armadas the United States were able to produce - and ready to loose (as they demonstrated in europe).
But, as an individual design, with its canard concept, performance and firepower, itīs really remarkable.
In my opinion, the jet version would have been underpowered with 900kp, and a radial turbojet
would have been more suitable for this fuselage.
Itīs a pity that nothing is known about itīs maneuverability and in-flight behaviour.
