Kei cars originated after WW2.
The Nakajima Aircraft Company produced aircraft up till the end of WW2. Then, since they had no other business and the Allies said 'no more airplanes', they closed up shop. The engineers needed something to do, and since they were prohibited from building airplanes, they turned their hand to building Subaru micro-cars.
