The Kyūshū J7W1 Shinden (震電, “Magnificent Lightning”) fighter prototype. Only two were finished before the end of the Second World War.

Reminds me of the World War I planes Britain flew, as they were unable to design a sequencer(?) to ensure the bullets from the mounted gun would fire in between the propeller blades and had to move the engine and propeller to the rear. One of the drawbacks of having the engine in the back of the plane is should the pilot crash nose first… they would be crushed.
