The Kawasaki Ki-10 was the best biplane fighter in Japanese service with its maneuverability. When later monoplane designs came along pilots wanted them to be as maneuverable as the Ki-10.
In September 1934 Kawasaki was asked by the Koku Hombu to design a bi-plane fighter and Nakajima (became the Ki-11) was asked to build a monoplane fighter. The Ki-10 was designed by Takeo Doi, Imachi, and Tojo. The Kawasaki Ki-10, though not as fast as the Nakajima Ki-11, it won the contract for production.
The Ki-10's frame was all metal with an alloy and fabric cover.
