Three Deities from the Heaven

At least, Ame-no-waka-hiko Ninigi-no-mikoto and Nigi-haya-hi-no-mikoto, all of them were said to have descended from the heavenly place, maybe Takama-no-hara, although only Nigi-haya-hi-no-mikoto had piloted the flying ship called Ame-no-iwa-fune. On the other hand, there was no description suggesting that the first Sumera-mikoto was able to fly by himself or to operate flying ships.
