Ki-62 fighter was a light fighter plane equipped with an air-cooled engine of which it conceived by the line of investigation which the Japanese army formulated in 1940.
However, the Nakajima airplane which is an order maker of ki-62 fighter was pressed with experimental model modification of the ki-43, and it was difficult to design a new light single seat fighter.
The Hayabusa type2 which was a performance gain type of the ki-43 was interpreted as the ki-62 after all, and the trial production of the ki-62 was stopped.
