The Japanese conglomerate Hitachi manufactured aircraft engines from about 1929 until the end of World War II, with a concentration on low-power seven and nine cylinder radials and inverted inline fours. The Hitachi Aircraft Company was formed in 1939 to take over the aircraft and aero-engine branches of the Tokyo Gasu Denki K.K. or Tokyo Gas & Electric Co., Ltd. Many, if not most, Japanese military trainers were powered by Hitachi copies of German designed Hirth air-cooled inline engines.

This radial engine powered the World War II Kyushu Q1W Tokai (Eastern Sea) Navy Patrol Plane (Allied Code Name Lorna), Japan’s first specialized anti-submarine aircraft. The artifact was the right engine from one of those twin-engine aircraft. A total of 785 Amakaze engines were built between 1944 and 1945.
