Behind many gods, a hidden one

Japan has long been home to a rich variety of spiritual beliefs, and animals have played a crucial part in its myth and religion. Visitors to Nara will have noticed the deer that roam freely there, an enduring sign of their sacred status. Foxes, snakes, horses, and crows have been woven into Shinto myth throughout history, each with its own symbolic meaning and its own regional faith. Among them the crow stands out as an enigmatic figure, tied closely to a hidden side of Japan's monotheistic tradition.

Many will be surprised to hear that Japan harbors a secret monotheism, since it is widely known as a polytheistic culture. Within Shinto, however, an esoteric monotheistic belief exists, one that remains largely unspoken, even among the Japanese. This hidden faith is bound to the crow, and its presence can still be felt today at Shimogamo Shrine in Kyoto, a site believed to continue a form of sun worship.

The Japanese myths recorded in the Kojiki and the Nihon Shoki are full of stories in which animals serve as messengers of the kami, or appear as kami themselves. The crow plays a crucial role in the legendary journey of Emperor Jimmu, Japan's first sovereign. According to the myth, Jimmu came from Hyuga, in present-day Miyazaki Prefecture. Hearing of fertile lands to the east, he set out to conquer the Yamato region (today's southern Nara Prefecture).

When he reached the strategic gateway into Nara by way of present-day Osaka, however, his forces were crushed by the local tribes. Unable to advance, he changed course and withdrew south along the Wakayama coast, reaching Shingu in Wakayama Prefecture. From there he meant to push inland, but a formidable natural barrier stood in his way: the Kii Mountains (紀伊山地).

The Kii Mountains are among the most treacherous terrain in Japan, with peaks of 1,000 to 2,000 meters, and are now known as the sacred pilgrimage route of the Kumano Kodo. At this critical moment a divine guide appeared: a mysterious three-legged crow called Yatagarasu (八咫烏). By legend, this sacred crow was sent from heaven as a messenger, to lead Jimmu safely over the mountain path and ensure his conquest of Yamato.

The crow has long been tied to the sun and is held to be an omen of victory. It remains a prominent symbol even now, adorning the emblem of Japan's national football team. At Kumano Hongu Taisha, the main shrine of the pilgrimage, Yatagarasu is venerated on shrine plaques and sacred banners. Thanks to this guidance, Jimmu crossed the hard terrain, led his forces to victory, and established his rule in what is now Kashihara, in Nara Prefecture, becoming the first emperor of Japan. The bond between the imperial line and the crow has lasted for centuries.

In ancient Shinto, animals were believed to be messengers of the kami, carrying divine will to human beings, and some were seen as manifestations of kami. Through its tie to the imperial line, the crow gained a unique religious standing, which grew stronger after Kyoto became the capital in 794. This is where Shimogamo Shrine comes into focus.

Shimogamo Shrine (下鴨神社) traces its origins to about 90 BCE, when the Kamo clan (賀茂氏), a powerful ancient family, enshrined its ancestral deity as a god of agriculture and fertility. The shrine's formal name, Kamo Mioya Shrine (賀茂御祖神社), means "the shrine of the Kamo ancestors." The deity worshipped there is Kamo Taketsunumi no Mikoto (賀茂建角身命), who, by legend, was the very Yatagarasu that guided Emperor Jimmu.

When crows came to be linked with the sun in Japan is unclear, but the belief is unlikely to be native. It seems that migrants from the Asian continent brought sun worship to ancient Japan and joined their practices to local traditions. The Kamo clan's tie to this belief suggests they may have been a newly arrived immigrant group, a theory supported by a growing body of archaeological evidence.

Many place names in Japan contain "Kamo," and some take them as traces of the clan's migration across the country. Examples include Shimogamo and Kamigamo Shrines in Kyoto, and places in Nara, Hiroshima, Aichi, Gifu, Niigata, Shizuoka, Shimane, Fukuoka, and Tokushima. These markers, scattered so widely, hint at the reach of the clan.

Strong evidence also lies in the legends of Shingu, Wakayama, where Emperor Jimmu is said to have landed before he reached Yamato. A long-lived local legend says that about 2,200 years ago Qin Shi Huang, the first emperor of China, sent 3,000 people across the eastern sea in search of an elixir of immortality (不老長寿の霊薬). The leader of the expedition, Xu Fu (徐福), is believed to have landed at Shingu and settled there with his followers for good.

The story is more than folklore. Xu Fu's voyage is recorded in the Shiji, an ancient Chinese history, and in 1982 a village tied to him was found in Jiangsu Province in China, confirming that he was a historical figure. The three-legged crow, known in China as the "three-legged sun crow" (三足烏), is a major symbol of Chinese solar myth, said to live in the sun itself. The parallels between the Chinese sun crow and Japan's Yatagarasu suggest that the Kamo clan may have come from the continent and brought their sun-worshiping beliefs with them.

The legendary Yatagarasu, a mysterious divine crow, may thus symbolize the arrival of an entirely different people and faith in ancient Japan. From the dawn of Japanese history to the present day its influence has shaped the spiritual landscape. Could the Kamo clan's origins truly be traced to the sun-worshiping traditions of ancient China? The question asks us to look past the myths, to the deeper, hidden roots of Japan's spiritual heritage.

Shimogamo Shrine in Kyoto, then, is more than a tourist stop. It is a place where one of Japan's most profound and secretive traditions still lives.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )
