[1] Hatsukaze engines were produced in very large numbers, as the powerplant for the license-built Bücker Bü 131 Jungmann variants that were the standard primary trainers for the Imperial Japanese Navy and Imperial Japanese Army.

The Hatsukaze Model 12 was the power section linked to a compressor to create a primitive jet engine called a motorjet; the resulting Ishikawajima Tsu-11 was intended to power Yokosuka MXY7 Ohka Model 22 flying bombs.

The compressed air was then ducted into a combustion chamber where a liquid fuel was sprayed and burnt.

The heated compressed air then exits through the tailpipe providing static thrust of 180 kgf (397 lbf).

The Tsu-11 was also selected to power the Yokosuka MXY9 Shuka ("Autumn Fire"), a trainer intended to prepare pilots for the Mitsubishi J8M rocket-powered interceptor.
