The Nakajima Homare ("Honor") was an air-cooled 18-cylinder double-row radial engine. It used the same size cylinders as the Sakae (bore of 130mm and a stroke of 150mm.) Though somewhat mechanically unreliable, later models became increasingly important towards the end of the war. The engine was notable for having a relatively small diameter, which reduced drag.
