maybe it is a KI-115
The Nakajima Ki-115 Tsurugi (Sabre) was an attempt at a simple, easy to build, suicide attack aircraft to help defend the Japanese homeland from invasion in 1945. Designed to be powered by any radial engine in the 800-1,300 horsepower range, its maximum speed was expected to be about 320 mph. This speed was only achieved after the fixed landing gear had been jettisoned, as landing was not required on combat missions. When flight testing began in March 1945, the landing gear gave problems, and ground handling and visibility were very poor. After modifications to the gear, about 100 were produced but the war ended before any saw operational use. In the hands of Japanese pilots with very little training and facing experienced Hellcat and Corsair pilots, the handful of Ki-115s would have had little chance.
