A captured G8N in US colors.

The Nakajima G8N Renzan was a Japanese four engine heavy bomber employed late in the war.


The G8N came about after the failure of the G5N Shinzan. Nakajima was requested to create a new heavy bomber by the Imperial Japanese Navy in February 1943.[1] The first example was completed in late 1944, and first flew on 23 October of that year. 64 were planned to be produced, but only 4 were completed before the project was cancelled due to lack of materials. Captured examples were later tested by the United States and found to have good performance.[1]

As only four G8Ns were built, there were no variants.
