The J7W Shinden was a very unique fighter for World War II as it was the only one that was a canard type aircraft with the horizontal tail in front.
The design was originally conceived by Captain Masaoki Tsuruno in 1943. His design was seen by the Dai-Ichi Kaigun Koku Gijitsusho (First Technical Arsenal of Naval Aviation) who then got involved with it.
A glider was built to test the aerodynamics of the canard design. After these tests were conducted Kyushu Hikoki K.K. was asked to manufactured the plane based on the designs.
The tricycle landing gear was completely retractable.
The engine was completely enclosed in the rear of the fuselage and there were vents in the side to provide cooling.
