Design and development

The engine was designed by Nakajima Aircraft Company after acquiring a license for the French Gnome-Rhone 14K. The Imperial Japanese Army Air Force called the first of the series the Ha-25 (ハ25) and later versions were designated Ha35, Ha105 and Ha115, while the Imperial Japanese Navy Air Service designation was Nakajima NK1, with sub-types identified by Model numbers; thus Nakajima NK1 Sakae 10, 20 and 30 series.

A total of 21,166 were made by Nakajima; 9,067 were manufactured by other firms.
