In March 1952, Kayaba Industry began the development of the Heliplane, a Gyrodyne, which combines the advantages of autogyro and helicopter.

Kayaba took advantage of experience producing the Ka-Go Ka-1 and Ka-2 autogyros, intended for reconnaissance, artillery-spotting and anti-submarine use, developed during World War II.

The wing was removed, and a three-blade main rotor with support structure was installed on the upper part of the fuselage.

Ishikawajima had developed the Ne-0 (Japanese: 石川島 ネ-0) ramjet during the war and tested it in flight beneath a Kawasaki Ki-48-II.

One prototype unit was produced and almost completed in March 1954 (Showa 29), but was damaged in July 1954 during tie-down testing.
