East Asia before its nations

Was there sun worship in ancient Japan?

It is hard to come close to this question, but from my own sense of it, the Jomon people left few traces of worshiping the sun. There are certainly traces in various places that they watched the movement of the sun, but that belongs to a different dimension from worship, so it cannot simply be called sun worship. Still, this way of seeing rests on my own arbitrary view, and from the sensibility of the Jomon it can be said that the base was a faith in which a spirit dwells in every being of nature.

The Ainu, for example, who seem to carry on the Jomon faith to a fair degree, had at their base a faith that took the divine power of beings in nature to be the dwelling of kamuy. They called the sun Tokapchup Kamuy and the moon Kunne Chup Kamuy, and in Ainu belief the sun is placed as a goddess and the moon as a god. There is, however, much room for argument here. The question is whether the relation of goddess and god in the faith the Ainu held was a lawful inheritance from the faith of the Hokkaido Jomon, the people who mainly lived where the Ainu lived, or whether the faith changed through the complex interbreeding of tribes.

Sun gods around the world divide into male and female, and in the background there are cases where faith changed through interbreeding with other peoples, so nothing can be said flatly. Still, I personally think that the female nature of the sun deity in Ainu faith arose by changing as a result of interbreeding with the tribes of the Honshu side of the archipelago.

To ask whether an ancient tribe like the Jomon had sun worship is itself odd, but it is a fact that from some age the worship of the sun began in an extreme form in the archipelago. And it seems to have been quite alien to Jomon faith, and the ground for that shows plainly in the qualities brought by foreign migrants. It is plain, for example, in how ritual tools never seen in the Jomon period are unearthed one after another from Yayoi sites, and such tools were indispensable instruments of faith in the sun god.

Without a doubt it was migrants who brought sun worship to the ancient archipelago and laid the base of the new religion born with the accession of Himiko, the queen of Yamato. This suggests that the Jomon, with a rich history of over ten thousand years, may not have held such a faith, which is to say that, against the animistic faith of the Jomon, they took up an attitude of separating the sun out clearly and worshiping it. A faith that presupposes such an early separation is not something the Jomon could accept, so it tells of a time when people with new values crossed the sea and began to live in the archipelago.

One legend that carries that old memory remains across the sea, on the Korean Peninsula. The place is near Pohang, on the eastern side of the peninsula. I think that a tribe based on ritual, with its base on this coast, was the group that brought sun worship to the archipelago. Who, then, were they?

The first premise is that in ancient times on the peninsula this tribe belonged to Silla. Silla was a country with a long history, from 57 BC to AD 935, and over that long history it exerted considerable influence on the Japanese side. Silla grew greatly around the fourth century, and in the later seventh century in particular it allied with the Tang, which was rising in China, destroyed Baekje and Goguryeo on the peninsula, and by 676 had unified most of it. This upheaval on the peninsula had an enormous effect on Japanese politics, and in those years countless refugees poured into the archipelago.

Silla was also a region that early on had active traffic with Shimane, Hokuriku, and other places on the Sea of Japan side of the archipelago. Ancient sea traffic tends to be made light of because it leaves no trace, but it is natural that several sea routes between the archipelago and the peninsula had been established since antiquity, and the traces are many, along the coast of the archipelago alone. It is generally thought that the route from the peninsula to the archipelago ran by way of Tsushima and Iki and landed in northern Kyushu, but that was the main route, and it does not mean there was no other.

In the relations between Japan and Korea since the modern age, however, neither side has yet cleared away the debt of heightened nationalism, so such historical facts tend to be ignored on one side, and no fruitful discussion has been reached. On the Japanese side, for example, it is hard to admit Korean influence, and a fact touching the line of the emperors is never admitted at all. In the same way, the Korean side stresses that it made Japan's history. What comes of carrying modern nationalism into ancient history can be grasped from the problem between Japan and Korea, and it is a great pity that there is still no sign of its resolving.

I judge nationalism to be a problem of modernity, and I will think of ancient history as another dimension. Within what was once Silla, the legend handed down on the coast near Pohang becomes important. The memory of antiquity still lies in the place. In this area there is a bay called Yeongil Bay (迎日湾), which means "welcoming the sun," a holy ground for worshiping the sunrise, and it was deeply tied to the sun worship of the Silla powers.

In fact the Samguk Yusa, a history with detailed records of Silla, records a legend that carries this ancient memory: the legend of Yeonorang (延烏郎) and Seonyeo (細烏女). It is set in the reign of Adalla, the eighth king of Silla, and since Adalla's reign was 154–184, it is presumed to overlap with the time of Himiko's accession on the Yamato side. The year of Himiko's accession is not known exactly, but the 170s or 180s are thought likely, and a story is told that during the time of Adalla the Wa queen Himiko sent an envoy to Silla. As I have written, however, interpretation changes greatly depending on which manuscript of the Chinese Records of the Three Kingdoms is taken at which stage, so the reality is hard to make out.

The Samguk Yusa is a privately compiled history edited at the end of the thirteenth century, after the Samguk Sagi, completed in 1145, the oldest surviving history on the Korean side. Its compiler was Iryeon (1206–1289), an eminent Buddhist monk of the Goryeo at the end of the thirteenth century, so we must remember that in speaking of Silla in the late second century there is a gap of more than a thousand years. Behind the compilation was Iryeon's dissatisfaction that the Samguk Sagi, compiled by the Confucian and Goryeo official Kim Busik (1075–1151), had followed Chinese methods of history so faithfully that the traditions, myths, and tales of ancient Korea were ruthlessly excluded. Iryeon dug out many documents on his own and recorded, above all, old Silla traditions, but because he was also a Zen monk and meant to link it to the spread of Buddhism, the old layers are sometimes hard to see. The Samguk Yusa is less a history than something private, compiled by gathering what we would now call folklore. Seen another way, that is exactly why it matters.

In East Asia, histories were basically a state enterprise built on the Chinese method, but at the same time, people outside, not officials or scholars, who were dissatisfied with that monolithic attitude, also made histories of their own as private records. In Japan this appeared at the scale of the state as the Kojiki and the Nihon Shoki. The difference between the Nihon Shoki, faithful to the Chinese method of compiling history, and the Kojiki, built on the traditions, myths, and tales of ancient Japan, is a difference of entirely different worldviews.

And in the Samguk Yusa is recorded a Silla legend that Iryeon unearthed: Yeonorang and Seonyeo. According to the legend, in 157, in the reign of King Adalla of Silla, a husband and wife living at Yeongil Bay rode a rock across to Japan, where they became king and queen. After they left, the sun and the moon of Silla lost their light, but when the silk that Seonyeo had woven was brought back to Silla and a rite was performed, the light returned. A point not to be missed here is that, because the Samguk Yusa was compiled at the end of the thirteenth century, it writes the place the Silla couple crossed to not as 倭国 (Wa) but as 日本国. I do not know how 日本国 (Nippon) was pronounced in the Samguk Yusa then, but it should not be overlooked that thirteenth-century common knowledge is the base.

The point, though, is that it does not say Yeonorang and Seonyeo moved to Wakoku. Wakoku before Himiko's accession was a very limited, scattered union of regions on the archipelago side, and is not the same as the archipelago. So in thinking about where Yeonorang and Seonyeo arrived, we must not take the usual view of history as given, without care, and think of a landing in northern Kyushu. Rather, if they crossed directly from Yeongil Bay to the archipelago, their landing is presumed to have been on the Sea of Japan side, in San'in or thereabouts.

Moreover, Wakoku in 157 is before Himiko's accession, and by the Gishiwajinden, Yamato was in an unstable age, out of control, with a great war among the male kings of the tribes. A tale that in this unstable age a tribe with Silla's sun worship came across to Wakoku and in time became king and queen is very interesting. In fact, judging by all my own research so far, this has a reality of ancient history that cannot be discarded as mere legend.

But as I said, from the standpoint of Japan's modern ideology, the theory that Silla was involved in one line of the Japanese is unacceptable, and conscientious scholars have argued for it many times, but all were wiped out, and in the mainstream of academia it is wholly ignored. Likewise, in the modern ideology of the Korean side, it is flatly asserted that the ancestors of the Japanese emperor were Silla, so it is a problem that must be thought of apart from nationalism. To open the history of East Asia sincerely, the cooperation of people in Japan, Korea, North Korea, and China who can think of this problem of nationalism separately will be needed, and those who carry it will probably be people outside the academy.

It goes without saying that Japanese are not Silla. What we can understand, at the least, is that it is suggested that on the Silla side in the mid-second century, the idea that the royal line of Wakoku was tied to Silla may have been shared in an early form. Of course it is not certain whether it leads to Himiko as the royal line of Wakoku, and since several kings were scattered across Wakoku then, tying it directly to Himiko is hard. But the importance of this legend comes down to the fact that Yeonorang and Seonyeo were an ordinary couple living on the coast, not of Silla's royal line. In other words, we cannot rule out that a tribe not of the royal line on the Silla side flowed into the royal line on the Wakoku side. More important still is that in the legend the one who left Silla first and entered 日本国 was the later king, Yeonorang, and that afterward his wife, Seonyeo, followed him there. What is this legend telling us?

I think Yeonorang and Seonyeo are not individuals but symbols of a tribe. A part of a tribe of ritual character, living in the area overlooking Yeongil Bay, the holy ground of Silla's sun worship, crossed to Japan, where sea traffic was already established, and did not come back, and a part of the worried tribe crossed after them and became king and queen. But the legend does not say where the royal line of Wakoku in which Yeonorang and Seonyeo lived stood, so we must avoid linking it in haste to the sun goddess Amaterasu or to Himiko. If this tribe from near Silla's Yeongil Bay crossed to the archipelago, they would have gone not by the main route, Tsushima to Iki to northern Kyushu, but directly, by way of Izumo or the Oki Islands, toward Hokuriku.

A provisional summary runs as follows. Yeonorang and Seonyeo in this Silla legend were unrelated to the royal line of Silla's Adalla, but for Silla they had the tribal meaning of guardians of the holy ground of sun worship, and a part of them became the main force that brought sun worship to the archipelago. Their base was Yeongil Bay, the holy ground that greets the sunrise, and a part of them, with the sun worship rites developed there, crossed the sea as they were and reached the archipelago. After an interval of time, later groups reached the archipelago, and these tribes of different lines entered into a mythic marriage and laid the base that led to the royal line of Wakoku. A mythic marriage is not the marriage of one person to another. It is symbolized by alliance, cooperation, or submission between tribes.

On this premise, we can see that the Silla legend fits, with reality, the establishment of the new religion founded on sun worship that came with Himiko's accession. That faith was what the Wei envoys took as kido (鬼道), and I take it to have been of foreign origin.

Is this interesting Silla legend, together with the rise of Himiko, queen of Yamato, a medium that carries an old memory of East Asia? Or is it a record that has carved the lost form of East Asia?

When the frame of nationalism that sets China, Korea, and Japan apart is dismantled, a grand history of the ancients that has never been thought of will come to the surface.

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 )

In Takahiro Mitsui's own words: “In a sense it is the most orderly society in the world, yet the Japanese themselves cannot actually explain where that order comes from.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )
