Yatagarasu

The road gave out somewhere in the mountains behind Kumano, and the army stopped where it stood. Ridge folded into ridge. The air was wet and smelled of cedar and rotting leaf litter, and it carried nothing useful: no smoke, no track, no sound of water running anywhere a man could follow it down. Kamu-yamato Iware-biko had already lost a brother to a war he was winning slowly, then lost his whole force to a poisonous vapour breathed out by a local god, and now he had lost the way. He slept badly. In the dream, the sun goddess told him she was sending a crow.

It came down out of nothing the next morning, black against a grey sky, and it was enormous. The Nihon Shoki records the emperor’s reaction almost as a shout. The coming of this crow, he says, is in due accordance with my auspicious dream. How grand. How splendid. Then Hi no Omi no Mikoto and Ōkume set off with their heads tipped back, watching a bird, and walked that way until the mountains let them out into the district of Lower Uda.

The name is a measurement that turns out not to be one. An *ata* is the span from thumb-tip to the tip of the middle finger, roughly eighteen centimetres, so eight of them makes about a metre and a half of crow. But *ya* in old Japanese meant eight and also meant many, in the way that a dozen can mean a lot rather than twelve, so the compound really conveys one thing only. It is a big crow. Neither the Kojiki nor the Nihon Shoki says a single word about its legs.

The third leg turns up about two centuries late. The Wamyō Ruijushō, a Chinese-Japanese vocabulary compiled around the 930s, glosses *yatagarasu* with the Chinese *yang-wu*: the red sun-crow that roosts inside the sun, whose shape people believed they could see in sunspots, and which had been drawn with three claws in China since the Han at the latest. Once the two birds were filed under one heading they never came apart again. Everything that makes the yatagarasu recognisable at a glance now, the extra leg and the solar glare behind it, crossed the sea inside a dictionary entry.

The chronicles cannot even agree who sent it. In the Kojiki the order comes from Takagi no Ōkami, the high god of generative force. In the Nihon Shoki it is Amaterasu herself, speaking straight into the emperor’s sleep, which is why the bird has been read ever since as a thing belonging to the sun rather than to the sky in general.

Its second appearance is stranger and much less flattering. Sent ahead as an envoy to demand the submission of two brothers holding the country in front of the army, it perches and calls out the heavenly summons. In the Kojiki the elder Ukashi brother answers with a whistling arrow, a bulbed head that shrieks in flight, and the bird withdraws. In the Nihon Shoki version the elder Shiki brother is simply disgusted: the Heaven-pressing god has come, he says, he is sick with rage over it, and why does this crow have to caw at him like that. He shoots at it too. The younger brother is frightened enough to pile food onto eight leaf-platters and set them out, and the crow eats, and then flies back to report which of the two can be trusted. A messenger of the sun goddess, driven off with noise, sitting down to a meal of appeasement.

Beyond size, no early source describes it. No plumage, no eyes, no voice beyond the ordinary rasp that made the elder Shiki brother wince. The old images that survive, on tomb walls and shrine seals and the pedestal of a lacquered reliquary, tend to reduce it to a flat black silhouette with three legs planted apart, sometimes inside a sun disc, and leave it there.

In Kumano the crow stopped being one bird and became a profession. Crows at the three Kumano shrines are *misaki*, settled spirits of the dead put into service as divine messengers, and the yatagarasu stands at the head of them, attendant on the Kumano deity. From the medieval period the shrines printed a talisman called the *goō hōin*, on which the characters are not written but built: somewhere between forty-two and seventy-two tiny crows, assembled into a legend in crow-script such as *Nachi taki hōin*, the treasured seal of Nachi Falls. Warriors wrote their oaths on the back of that paper. Princeton holds five such invocation clauses from the Saji, a warrior family of Kōga district, dated between 1556 and 1615, the ink gone brown and the crows still legible. The oath worked on a threat: break it and the gods you had just invoked would come for you, and a Kumano crow would drop dead somewhere for the lie. Near the end of the Edo period Takasugi Shinsaku turned that belief into a love song, offering to kill every crow in the three thousand worlds for the sake of one more morning in bed.

A separate strand of the tradition says the crow was a man. The Shinsen Shōjiroku, an 815 register of clan pedigrees, states plainly that the yatagarasu was the incarnation of Kamo Taketsunumi no Mikoto, who then became the ancestor of the Kamo no Agatanushi; the Yamashiro Fudoki tracks him from Katsuragi in Yamato up to the river confluence in the north of Kyoto where the Shimogamo Shrine stands today. The Nihon Shoki, for its part, has the crow’s own descendants installed as hereditary officials of the palace household. Whatever else the bird is, it is also a title deed.

The modern career is stranger still. In 1931 the Japan Football Association adopted a three-legged crow with a ball, proposed by the classical Chinese scholar Uchino Tairei and drawn by the sculptor Hinago Jitsuzō, and it has been on the national shirt ever since. In 2024 the association asked a textbook publisher to soften a line calling the crest simply the yatagarasu, pointing out that the three legs come from the Huainanzi rather than from anything in Japanese scripture. A football association filing a correction about the provenance of a mythological bird’s leg count is one of the more precise things Japan does.

What it can do is narrow and absolute. It knows the road when nobody else does, it can be dispatched as a herald and understood by the people it is sent to, and it can carry an answer back. Its arrival converts a stalled column into a moving one without a blow being struck, which is the whole of its power and the reason it was worth a place in a founding myth.

What it cannot do is nearly everything else. It carries no weapon and makes no threat; a man with a noisy arrow got rid of it once, and it left. It cannot compel, only precede, and it only works on people willing to tip their heads back and follow a bird into worse country. Nobody summons it either. The dream comes first and the crow comes after, and it goes where it was sent rather than where it is wanted. In the same century that made it divine, Sei Shōnagon put flocks of cawing crows on her list of hateful things.

Frequently Asked Questions

What is the Yatagarasu?

Yatagarasu is a giant crow in Japanese mythology, sent from heaven to guide the future Emperor Jimmu through the Kumano mountains to Yamato. It appears in both the Kojiki (712) and the Nihon Shoki (720) as a divine guide and messenger. In Kumano it is also worshipped as the chief messenger of the Kumano deity, and the Shinsen Shōjiroku identifies it with the clan ancestor Kamo Taketsunumi no Mikoto.

Why does the Yatagarasu have three legs?

The three legs are a later borrowing and appear nowhere in the Kojiki or the Nihon Shoki. The oldest text that gives Yatagarasu three legs is the Wamyō Ruijushō, a Japanese-Chinese vocabulary of about the 930s, which identifies it with the Chinese three-legged sun-crow. Kumano Hongū Taisha now explains the three legs as heaven, earth and humanity.

Who sent the Yatagarasu to Emperor Jimmu?

The two chronicles disagree. The Kojiki says the crow was dispatched by Takagi no Ōkami, while the Nihon Shoki has the sun goddess Amaterasu appear in Jimmu’s dream and promise to send it. Both versions place the crow’s arrival immediately after the army was stranded in the mountains with no passable road.

Why is the Yatagarasu on the Japan national football team’s crest?

The Japan Football Association adopted a three-legged crow holding a ball in 1931, proposed by the scholar Uchino Tairei and designed by the sculptor Hinago Jitsuzō, taking the guiding crow as its motif. In 2024 the association asked a textbook publisher to amend a description of the crest, noting that the three-legged form derives from the Chinese Huainanzi as well as from the Yatagarasu myth.

What does the Yatagarasu look like?

The early sources describe only its size. The name means roughly “eight-span crow”, and since *ya* meant both eight and many, it amounts to saying an unusually large crow. No eighth-century text describes its plumage, face or legs, and the familiar three-legged silhouette comes from later art influenced by Chinese sun-crow imagery.
