In Japanese mythology, this flying creature is a raven or a Jungle Crow called Yatagarasu and the appearance of the great bird is construed as evidence of the will of Heaven or divine intervention in human affairs.
Although Yatagarasu is mentioned in a number of places in the Shintō canon, the depictions are primarily seen on Edo wood art, dating back to the early 1800s wood-art era. Although not as celebrated current day, the crow is a mark of rebirth and rejuvenation; the animal that has historically cleaned up after great battles symbolized the renaissance after such tragedy.
Yatagarasu the Crow-God himself is symbolic specifically of guidance. This great crow was sent from heaven as a guide for Emperor Jimmu on his initial journey from the region which would become Kumano to what would become Yamato. It is generally accepted that Yatagarasu is an incarnation of Taketsunimi no mikoto, but none of the early surviving documentary records are quite so specific.
In more than one instance, Yatagarasu appears as a three legged crow in Kojiki.
