The planned aircraft The Project Z aircraft was to have six engines; the Nakajima Aircraft Company quickly began developing engines, proposing twinned Nakajima Ha-44 engines (the most powerful aircraft engine available in Japan at the time).
Designs were presented to the Imperial Japanese Army, including the Nakajima G5N Shinzan, with 6 prototypes built; Conversion of the Kawanishi H8K (sometime wrongly designated G9K Gunzan), concept only; Nakajima Fugaku (sometime wrongly designated G10N), project only; Kawasaki Ki-91, scale model only.
None, save for the G5N, developed beyond prototypes or wind tunnel models. Late in the war, Project Z and other heavy bomber projects were cancelled.
