The Kokusai Ki-59 light transport aircraft was an improved version of an unsuccessful civilian design, the Teradakoken TK-3. The Japanese Army substituted more powerful engines than those in the original design, and modified the shape of the nose, undercarriage fairings, and vertical tail surfaces. The aircraft that resulted was acceptable in performance. However, it was soon superseded by a transport version of the Hickory, since the passenger capacity of "Theresa" was inadequate for paratroop drops.

The design was revived in December 1941 as the basis for the Ku-8 "Gander" glider.
