Since January 1941, the production of an early version of the "Type Lo" at Kawasaki was phased out after the release of 55 copies and the plant completely switched to production of the Ki-56. Production of "Type Lo" at Tachikawa continued until 1942 and ended with the release of only 45 copies, ie. a total of 100 Type Lo aircraft were produced.
Ki-56 Thalia. The production of the aircraft was additionally launched at the Kawasaki company. Takeo Doi took over the improvement of the aircraft on Kawasaki. The weight of the wing structure was reduced, the Fowler flaps were redesigned. The length of the fuselage was increased by 1.5 m with an increase in capacity to 16 passengers or 14 soldiers or 10 paratroopers. A large cargo hatch with a door was installed on the left side, a cargo winch was placed in the cabin, the aircraft could carry up to 2,400 kg of cargo.
