No tribe's god may rule the alliance

This year again I was able to travel across Japan and carry out my own research. As usual I set several themes and ran them side by side, and the one I weighted most was the search for the origin of Japanese mythology as it is set down in the Kojiki and the Nihon Shoki: how was it born? Japan's myths were handed down by word of mouth for a very long time. In the earliest period they began from the traditions of a tribe in a single place, and were layered as tribes merged into composite tribes and clans.

The joining of different peoples is symbolized in myth mainly by marriage. What we must not mistake is that these are not stories of particular people actually marrying. They symbolize alliances between peoples. There must have been many patterns of joining by marriage, but when several peoples came together and rose into one larger tribal body, what I see is that they did not bring forward the god from any one tribe's tradition. They created and set up a new god. Bringing up the god of one particular tribe would have upset the balance of power among them and made a peaceful rule impossible, and I think the practice was born from that.

The more different peoples merged, in other words, the less they clung to existing gods and fought with other tribes, and the more they created a new god first, under a common ritual, to keep the balance of power stable. By this interesting method they achieved a peaceful rule. What is most interesting is that, with the genealogy of this newly created god as the premise, the gods of each tribe in the merger were set into the genealogy in the reverse direction. By reverse I mean that the genealogy was not designed along a line of continuous linear time, from grandparents to parents to children to grandchildren. It was designed to reach back into later generations.

That may be a little hard to follow. Suppose there were four tribes. The god that each tribe worshipped was inserted retroactively into the genealogy of the children, descendants or ancestors of the god the four had created together. In this way the traces of the composite tribes could be firmly built into the genealogy of the one god they had made in common. I think this invention made a very stable rule possible and became the source that allowed it to expand steadily. It had already begun as a large current from the middle of the Jomon period.

Countless examples can be seen in the myths too. Myth places great weight on genealogies of the gods, and that brings a problem. The basic myths we can consult today are the Kojiki, completed in 712, the oldest surviving book in Japan, and the Nihon Shoki, completed in 720. Both came together in the first half of the eighth century, a very recent time, under new rulers, and it cannot be denied that they carry a strongly political, national picture.

In fact the married pair of sovereigns who ruled this new age become important: Emperor Tenmu (the fortieth; reigned 673-686) and Empress Jito (the forty-first; reigned 690-697). In the reigns of these two, when myth, tradition and legend were unified and set down in a single book, the genealogy of Japan's gods split in two. This unification, though, covered the myths, traditions and legends of the clans of retainers and the regional level held by the emperor of the time, and the myths of tribes beyond the broad reach of rule were still ignored. At that point there was no Japan. At the emperor's level too there must once have been countless genealogies, but from Tenmu to Jito they were gathered and arranged, and in the end divided into two main lines of gods. The gods are Takamimusuhi and Amaterasu.

Takamimusuhi and Amaterasu are very important gods in the myths. Amaterasu, the ancestral god of the imperial house to this day (the chief deity of Ise Jingu), is known abroad, but many people do not know Takamimusuhi (the situation is the same in Japan).

My research has shown, however, that before the Kojiki and the Nihon Shoki belief in Takamimusuhi had enormous influence, and belief in Amaterasu was practiced only in limited places. By the reigns of Tenmu and Jito, a new movement of belief suddenly arose that set Amaterasu as the ancestral god of the emperor. Or rather, more exactly, it was a political movement more than a movement of belief. Conversely, until this age there was no custom of the emperor himself worshipping Amaterasu as his ancestral god. There must have been a prototype. But the history of how the god called Amaterasu came into being is very complex, and I will take it up carefully in separate essays later. Put simply, Amaterasu is now generally recognized as a goddess, but anciently was a male god, and in reality was a god who swung between male and female. In fact many old texts take Amaterasu as a male god.

What matters here is that Amaterasu was set as the emperor's ancestral god in the span from Tenmu to Jito. In particular Empress Jito, a woman on the throne, tended to raise her own authority by identifying herself with Amaterasu, and it is possible to think that Jito's own projection and worship were involved in Amaterasu's formation. Belief at Ise Jingu, the holy place that enshrines Amaterasu, began in Jito's reign, and from about this time it was rapidly raised into a national belief.

When a person with the right of succession ascends the throne, a secret rite called the daijosai (大嘗祭) has been performed. No one knows what is done in it even now. The secret of by what rites the heir becomes emperor is passed down by word of mouth from each emperor to his heir, so no one but the emperor, the heir and one other knows it. Many books have appeared on the daijosai, but all are conjecture and are hardly worth consulting. The first to establish the daijosai was also Emperor Tenmu. Tenmu took up eagerly the ritsuryo (律令) system that Tang China had adopted as the foundation of building a strong state, and aimed to build Japan's first ritsuryo state, so these matters were organized and set in order one after another in his reign. It is a very important turning point in history. Put simply, the ritsuryo system governs a state by criminal law, called ritsu, and administrative law, called ryo. Within this framework the emperor intended to unify the old traditions of the emperor and the clans, and this is the source from which the Kojiki came to be.

The daijosai was interrupted many times by war and social upheaval but continued. Most recently it was held for the first time in 200 years when Emperor Meiji took the throne, and it went on through Taisho, Showa and Heisei, and was held again in November 2019 when the present emperor ascended. The daijosai, in other words, was not performed from the time of the legendary Emperor Jimmu, whom the genealogy sets as the first emperor. It was set as a rite of the imperial house from Tenmu. It is worth noting that the systematizing and arranging of all these things is tied to the appearance of Tenmu. Conversely, since the systematization and ordering of Japanese history center on Tenmu, without study of his age we cannot understand Japanese history and all that attaches to it. In a sense it is the age that most requires care.

There is a possibility that hegemony shifted here from the powerful class that followed the genealogy of Takamimusuhi to a new force that followed the genealogy of Amaterasu, and it shows in the very different placement in the Kojiki myths. The opening of the Kojiki has been published by Kokugakuin University, which can be called Shinto's university, with an English version added, so I will set it out here once. Scholarly readings always carry some distortion, and if there is a chance I would like to read it in my own way. In Japanese I have already gone a long way, but there are problems between the languages that make it hard to put into English, and I will think for a while about what to do.

天地初發之時、
於高天原成神名、
天之御中主神。［訓高下天云阿麻。下效此］
次高御産巣日神。次神産巣日神。
此三柱神者、並獨神成坐而、隠身也。

English

When Heaven and Earth first became active,
a deity came into existence in Takamanohara.
Its name was Amenominakanushi no kami.
Next Takamimusuhi no kami appeared, and then, Kamumusuhi no kami.
All three came into existence as solitary deities, and they hid their bodies.

Takamimusuhi is one of a pair, the two most important Japanese gods called the "gods of musuhi." The other is Kamumusuhi. These are not gods with substance. They express the working of non-separation itself as a god. The Japanese concept of musuhi (ムスヒ) is so advanced that nine times in ten people misunderstand it. It is one of the oldest concepts expressing non-separation, not separation. I also meet people who often get it wrong: it is not musubi (ムスビ) but musuhi that is the old word. And musuhi is not itself one prototype concept. It is mus-hi (ムス-ヒ). Many people think it is only a difference between "hi" and "bi," but musubi does not hold as a concept. Whenever I talk about Japan, I always watch which of the two the other person uses, and sadly most Japanese no longer understand it and nearly all read it as musubi.

In the concept of musuhi, hi (ヒ) is at the root, and by "musu" (ムス), to bring forth, to bind together, all things are generated in non-separation. There is a movement, hard to put into words, of hi binding together. As an image, it is what is generated at the threshold where a right-turning and a left-turning spiral bind. Hi is one of the oldest concepts and cannot be expressed in a word. Two years ago I traveled to many places to look at hi alone, and I came away with enough for a thick book (it was so difficult that I held back the release).

From my own research I think the concept of hi comes from the Jomon. Himiko, the queen of about the third century who appears in the Records of Wei (the Weizhi), the valuable Chinese source describing the oldest Japan, is also not a queen with the proper name "Himiko." It is hi-miko: a miko (巫女), a shaman, who bears hi. So I think Himiko was succeeded generation after generation, as the emperors were, in a form like succession to the throne. It also matters that the Kojiki and the Nihon Shoki write musuhi differently. The Kojiki writes it 産巣日, and the Nihon Shoki writes 産霊. I will touch on this little by little next year. This is not something to understand with the head but to grasp with the heart. Personally I suspect that if people in the English-speaking world can grasp this sense, a new possibility may arise that nullifies the structure of their language, with its subject and copula.

The Kojiki opens with the myth in which the god Amenominakanushi comes into being first, and then Takamimusuhi and Kamumusuhi. It describes how the origin of life itself begins to act, and all things are generated in non-separation at the place called Takamanohara. So Takamanohara is a place that exists everywhere, and yet has locality and particularity.

From this place the gods come into being one after another. In fact Takamimusuhi and Amaterasu were originally separate gods worshipped by migrants of different lineages. At some point they were Japanized and finally set into one genealogy. The roots of their sources on the continent were different, though. So when the myths are read closely, the gods of the Takamimusuhi line and the gods of the Amaterasu line prove to be different. Among some people who still hold Shinto belief today, there is even a spiritual movement that takes Takamimusuhi, not Amaterasu, as the source, and tries to restore balance by correcting the historical belief that has leaned toward Amaterasu and reviving belief in Takamimusuhi. That is how strong belief in Takamimusuhi was in ancient times, and it is now forgotten.

Conveying Japanese myth in any language but Japanese is, I always think, difficult, even impossible. But if we argue with that impossibility understood, perhaps something may get across. I released this essay today because tomorrow, the last day of the year, I plan to release an essay that sets down my reflections with the photographs I took, drawing on the results of the research I carried out in many places in 2025. It is too vast to show all of it (there are over 7,000 photographs from this year alone). But, as I said at the start, from the theme of seeking the origin of how Japanese myth came to be, I plan to open a view of my own that mixes in a historical study of the "Transfer of the Land at Izumo," the most important tale in Japanese myth.

The end of the year is at last near. Please take care of yourselves and spend it in peace.

Takahiro Mitsui's thesis on this question: Musuhi: A New God for an Alliance of Peoples — What is musuhi, and how were Japanese myths born? Takahiro Mitsui's answer: musuhi, not musubi, is hi bound together so all things arise in non-separation; merging peoples did not raise one tribe's god, they created a new god under a common ritual.

Takahiro Mitsui's thesis on this question: When Miko Ruled: The Yayoi Order Before Male Kings — Were ancient Japanese rulers shaman women? Yes, says Takahiro Mitsui, a Japanese philosopher born in 1991, from fieldwork at the shrines of Yakami-hime and Toyotama-hime: the Yayoi had a shamanic queen-culture, Himiko was hi-miko, and male-line-only succession became law only in 1889.

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: “The moment good and evil are lifted onto the same ground and argued as a duality, one is already wrong.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )
