The Hitachi TR.1 was a small airliner developed in Japan in 1938, produced in small numbers as the TR.2. It was a low-wing, cantilever monoplane with retractable tailwheel undercarriage and a fully enclosed cabin. The design strongly resembled the Airspeed Envoy that it was intended to replace in Japanese airline service. Testing of the TR.1 prototype commenced on 8 April 1938 at Haneda Airport, but it suffered a serious accident on 22 June due to a landing in which one of the main undercarriage units failed to extend.

The TR.2 was a revised and strengthened design with a larger wing area, and main undercarriage that only semi-retracted. Twelve examples were built in a small series, but performance was not as good as the TR.1, since the modifications to the design had added 260 kg (570 lb) to the aircraft.
