This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Yatagarasu (Japanese)
In Japanese mythology, this flying creature is a raven or a jungle crow called Yatagarasu ("eight-span crow") 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 Shint?, the depictions are primarily seen on Edo wood art, dating back to the early 1800s wood-art era.
Although not as celebrated today, 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 as a crow-god is a symbol specifically of guidance and in more than one instance, Yatagarasu appears as a three legged crow.
