The Tachikawa Ki-72 was a design for an improved version of the Ki-36 Army Type 98 Direct Co-operation Plane. The Ki-72 would have had a fully retractable undercarriage, in place of the fixed wheels of the Ki-36, and would have been powered by a 600hp Hitachi Ha-38 engine instead of the 450hp engine used in the earlier aircraft. The Ki-72 did not progress beyond the design stage.
