The Ki-61 wasn't the only fighter design to be powered by the Ha-40 inline engine. Kawasaki also experimented with an unusual twin-engine design conceived by Takeo Doi in 1939 and approved for prototype development in October 1940 as the Kawasaki "Ki-64".
The Ki-64 had both engines in tandem, straddling the cockpit and driving a single contra-rotating prop system with twin three-bladed props. The combined engine was known as the "Ha-201", and generated 1,755 kW (2,350 HP) take-off power. It featured an unusual steam cooling system with radiators in the wing and flap surfaces. The front engine used the right wing for cooling, while the rear engine used the left wing. The Ki-64 had a vague configurational resemblance to the Hien, though it was larger.
