There are many creatures often little known outside Japan that are featured in Japanese folklore. I aim to draw them with my own interpretation of written descriptions, old paintings, sculptures and existing animals.
Yatagarasu apparently have no description of having three legs in the first instance it appears in Japanese mythology. There are, however, three legged crows in other Asian mythologies that represent the sun, which probably are the reason Yatagarasu became known as a three legged crow. In Japanese mythology, Yatagarasu was sent by Takamusubi god to Emperor Jinmu to lead the way from Kumano to Yamato.
Shachihoko is a fish with a tiger face, with its tail always pointing the sky. They are said to be able to call rain. Hence their figures were placed on the roofs of castles, temples and other large buildings in Japan to protect them from fire. "Shachi" (シャチ) also means killer whale, but Shachi-hoko's apparance is very different from it.
