Yatagarasu

The Nihon Shoki places the episode during Emperor Jimmu's campaign to move his forces from Kyushu to the Yamato plain, a journey the chronicle treats as the founding conquest of the Japanese imperial line. After a costly defeat and the death of his brother, Jimmu lands at Kumano, on the rugged Kii peninsula, where the terrain grows so hostile that his army loses its way entirely among the mountains. At this point heaven intervenes: a great crow with three legs, sent down at Amaterasu's command in some versions and at the high god Takamimusubi's in others, appears to lead the army through the wilderness to Yamato, where Jimmu is eventually able to establish his rule and, by the traditional chronology, ascend as Japan's first emperor in 660 BCE. The bird functions in the narrative purely as an instrument of heavenly favor, confirming that Jimmu's conquest carries divine sanction even when his own military judgment has failed him.

Unlike Susanoo's serpent, Yatagarasu is never a threat to be overcome, only a messenger to be followed, and the myth gives it no independent personality or desire beyond fulfilling its errand. The name itself carries a related motif: yata means eight ata, an old unit of hand span length, so the name describes an enormous crow rather than counting anything eightfold in a literal sense, an echo of the same numerically stylized grandeur that marks Susanoo and the serpent story elsewhere in the same two chronicles.

The Kumano shrines most closely tied to the legend, Kumano Hongu Taisha chief among them, keep Yatagarasu as a living emblem long after Jimmu's campaign passed from history into founding myth, and pilgrims along the Kumano Kodo routes still encounter the three legged crow in shrine talismans and signage. Its clearest modern afterlife, though, is secular: the Japan Football Association adopted Yatagarasu as its crest in 1931, drawing on the bird's role as an unerring guide toward a destination, a natural mascot for a sport played toward a goal, and Japanese national teams are still popularly described as walking Yatagarasu's road.

Comparative mythologists also note that a three legged, sun-associated crow is not unique to Japan; a near identical bird appears in Chinese solar mythology as a resident of the sun disc, and some scholars trace the Japanese figure to continental influence carried across with early Yamato-period contact with China and Korea, though the two traditions developed distinct roles, the Chinese bird as a solar inhabitant and the Japanese one as an earthbound guide. Whether inherited or independently imagined, Yatagarasu remains one of the few creatures from the Kojiki and Nihon Shoki whose image is now more familiar from a football badge than from the scripture that first named it.
