History
First flight	1943

The Tachikawa Ki-70 "Clara" was a high speed photo reconnaissance aircraft that was tested for the Japanese Air Force in prototype form but never entered production. The Ki-70 was the intended successor to the Mitsubishi Ki-46 but was difficult to handle and was slower than the Mitsubishi Ki-46. The Ki-70 was first flown in 1943 but was found unsatisfactory and the program was terminated. Three aircraft were built.

In later years the Ki-70 was used to disprove supposed photographic evidence concerning Amelia Earhart's supposed capture by the Japanese before World War II.^{[citation needed]}

Using the familiar layout of aircraft such as the Mitsubishi G3M bomber and its planned predecessor the Mitsubishi Ki-46, the Ki-70 had a twin tail and narrow fuselage, an extensively glazed nose and second cockpit facing aft for the gunner.
