A Living Tradition of Japan

On the shores and in the forests of Hokkaido, the northernmost of Japan's main islands, the Ainu people maintained for centuries a religious life organized entirely around the presence of spirits. In the Ainu world, nothing was inert. Every river, mountain, fire, and storm harbored a kamuy — a spirit-being who had taken temporary physical form to visit the human realm. The bear who moved through the forest was not merely an animal but the God of the Mountains himself, descending in fur and breath to receive the hospitality of the people. The flame in the hearth was not merely fire but Kamuy-Fuchi, the grandmother of the hearth, whose presence mediated every prayer, every birth, every death, every word offered to the spirit world.

The Ainu religion is one of the great animist traditions of East Asia — and one of the most thoroughly suppressed. In 1899, the Meiji government classified the Ainu as "former aborigines" and stripped them of their land, language, and religious practice. By the 1980s, fewer than one hundred native Ainu speakers remained. The tradition had been driven underground or into the memory of elders who had no students. That any of it survived — and that it is now, in the first decades of the twenty-first century, being recovered and practiced again — is itself a form of the iomante: the act of sending something precious away from the human world, in trust that it will return.

I. The People and the Land

The Ainu are the indigenous people of what is now Hokkaido, Japan's northernmost main island, along with the southern half of Sakhalin Island and the Kuril Island chain stretching northeastward toward the Kamchatka Peninsula. Their presence in these territories substantially predates the arrival of the Yamato Japanese; archaeological and genetic evidence places the Ainu's ancestors in the region at least three thousand years ago, and possibly much longer.

The Ainu are ethnically, linguistically, and culturally distinct from the Yamato Japanese who form the majority of Japan's present population. Their language — the Ainu language, or Aynu itak — is an isolate, unrelated to Japanese or any other known language family, suggesting a long independent development. Their physical appearance, including facial hair notably more prevalent than in Yamato populations, prompted considerable interest and theorization from early Western visitors and Japanese scholars. The question of Ainu origins remains a matter of ongoing research; genetic studies have found connections to the Jōmon people, the prehistoric inhabitants of the Japanese archipelago who preceded the migration of rice-farming populations from the Korean Peninsula roughly two to three thousand years ago.

Current estimates place the Ainu population at approximately twenty-five thousand to thirty thousand in Hokkaido, though the actual number of people with Ainu ancestry is certainly higher. Generations of discrimination, assimilation pressure, and the social costs of Ainu identity have led many individuals to conceal or suppress their heritage. Japan's 2019 Act on Promoting Ainu Culture officially recognized the Ainu as an indigenous people — the first such legal recognition in Japanese history — and is widely understood to have made visible identification as Ainu more possible than at any previous point in the modern era.

II. The Kamuy — A World of Spirits

The foundational structure of Ainu religion is the kamuy system — a comprehensive animist framework in which spiritual presences pervade every dimension of the natural and human world.

The term kamuy (also spelled kamui) encompasses a range of meanings: god, spirit, powerful being, sacred presence. Every natural phenomenon — rivers, mountains, fire, storms, disease, tools, animals — contains or is animated by a kamuy. The theological claim is not merely that a few special objects are sacred while others are ordinary. It is that the ordinary world is comprehensively spirit-inhabited, that every encounter with nature is an encounter with spiritual agency, and that human wellbeing depends on the quality of the ongoing exchange between human beings and the kamuy presences surrounding them.

The kamuy are understood to move between two realms. Their native home is Kamuy Mosir — the "Land of the Spirits," a world parallel to but distinct from the human world (Ainu Mosir, "Land of Humans"). The kamuy visit the human world by taking on physical forms: animal bodies, natural phenomena, useful objects. When a hunter kills a bear, he is not destroying but releasing — the spirit within the bear's body is freed to return to Kamuy Mosir, where it will report to the other kamuy on the treatment it received from the humans. This report is consequential: kamuy who were treated with reverence will visit again; those who were treated carelessly will not return, and the animals and plants that sustain human life will disappear.

The principle organizing this entire framework is ramat — the sacred life force or spiritual substance present in every living being and object. Ramat flows from the kamuy into the physical world and back again. The practice of Ainu religion is fundamentally the maintenance of proper ramat exchange: receiving what the kamuy give, treating it with reverence, and returning it with ceremony and gratitude.

Among the many named kamuy, several are particularly central. Kamuy-Fuchi (also called Ape-Fuchi or Apehuchi), the hearth-fire goddess, is considered the most important of the household kamuy, mediating all communication between the human world and the spirit world. Kim-un-Kamuy, the God of the Mountains, manifests most often as the brown bear and is the subject of the tradition's most elaborate ceremony. Chikap Kamuy, the eagle owl, is the guardian of the village and a messenger between worlds. Repun Kamuy, the deity of the sea, manifests as the orca and governs the marine realm essential to Ainu subsistence on the coasts of Hokkaido. Wakka-Ush Kamuy governs rivers and fresh water. Below these great kamuy run hundreds of named spirits governing every dimension of human and natural life — including sinister entities (wen kamuy, "bad kamuy") whose interference causes illness and misfortune.

III. The Chise and the Hearth

The primary space of Ainu religious life is the chise — the traditional dwelling — and its center is the hearth where Kamuy-Fuchi lives.

The chise is a thatched-roof structure typically oriented east to west. Its most religiously significant feature is the rorun-puyar — the "window of the gods" — a small opening on the east end of the building, the direction associated with sunrise and divine approach. Sacred objects are passed in and out through the rorun-puyar; the spirit of the dead leaves through it; ceremonial tools are taken in and out through it rather than through the ordinary entrance. The spatial grammar of the chise enacts the theological conviction that the human household exists within a field of ongoing spiritual exchange.

At the heart of this exchange is Kamuy-Fuchi. As the spirit of the hearth fire, she is permanently present in every household. All communication with the other kamuy passes through her: prayers addressed to more distant spirits are first reported through the fire; offerings made at outdoor altars are made efficacious through her mediation. She is the grandmother of the household, the keeper of the threshold, the one who receives the newborn soul from the spirit world at birth and escorts the dying soul back across the threshold at death. Ainu life is lived in her presence.

The domestic religious practice that Kamuy-Fuchi structures is woven into daily life without clear separation between "religious" and "ordinary" activities. Before a meal, a small offering is tossed into the fire. Before fishing or hunting, prayer is addressed through her to the relevant kamuy. The care given to the hearth fire — the fact that it is not allowed to go out casually, that it is fed with intentionality — is itself a form of reverence. An extinguished hearth fire is a spiritual emergency as well as a practical one.

IV. The Inau and the Logic of Offering

The primary ritual object of Ainu religion is the inau (plural: nusa) — a wand made of shaved willow or other sacred wood, with the shavings left attached in decorative curling layers.

The inau embodies the logic of Ainu gift-giving to the spirits. It is crafted from living wood — a material itself alive with kamuy presence — shaped by human hands into a form of beauty and attention, and offered to the spirit world as an expression of respect and need. The specific form of the shavings, the number of curls, the species of wood, and the manner of carving all carry information: an inau for Kamuy-Fuchi differs from one made for a river kamuy or for the spirit of a killed animal. The craft of inau-making is thus a form of sacred literacy — a language addressed to the kamuy through wood and care.

Individual inau are placed before the fire, tied to outdoor altar posts, or held during prayer. Grouped inau are arranged in nusa — fence-like altar structures, typically on the east side of the household near the rorun-puyar, that accumulate offerings over time. On ceremonial occasions, nusa altars may include bear skulls mounted on decorated poles, representing the spirits of bears whose sending ceremonies have been conducted. The nusa is the household's record of spiritual exchange: the accumulated history of what has been received from the kamuy and what has been returned.

Alongside inau, the Ainu offer tuki (sake) in lacquered vessels, morsup (a fermented beverage), dried meat and fish, and other foods. The offerings are not consumed — they are gifts. The theological reasoning parallels the kamuy system itself: the spirit that inhabits the food, released into the spirit world through the act of offering, becomes spiritual sustenance for the kamuy who receive it. What circulates between the human world and the spirit world is not merely matter but relationship.

V. The Iomante — Sending the Bear Home

No ceremony in the Ainu tradition is more central, more elaborate, or more theologically concentrated than the iomante — the bear-sending ceremony. It is the fullest expression of everything the Ainu religion knows about the relationship between the human world and the spirit world.

The word iomante means, approximately, "to make that go" — to send. The object to be sent is a bear. But to understand what the sending means, one must understand the Ainu theology of the bear.

The brown bear (ursus arctos) is understood in Ainu religion as the physical form taken by Kim-un-Kamuy — the God of the Mountains — when he wishes to visit the human world. The bear is not merely an animal that the kamuy inhabits; in the fullest sense, it is the kamuy, present in bear form. When hunters encounter a bear, they are encountering a divine visitor. When they kill it, they are not killing but releasing: freeing the spirit from its fur-and-flesh vehicle so that it can return, enriched with the gifts of hospitality, to Kamuy Mosir.

The iomante begins not at the moment of the bear's death but years before it. A bear cub — ideally one found in a den during the winter hibernation of its mother — is captured alive and brought to the village. The cub is nursed by an Ainu woman, raised in the household as a member of the family, and treated with affection and care for one to two years. Children play with it. It is fed the best food. It is given inau. It is spoken to in the formal address that one uses with an honored guest. The community knows the whole time that the cub will eventually be sent home, but this knowledge does not attenuate the care — it intensifies it. The better the cub is treated, the better Kim-un-Kamuy's report to the other kamuy will be when it returns.

When the cub has grown large enough, the ceremony is prepared. Village members come from neighboring settlements. The bear is ceremonially brought out and addressed with formal speeches of gratitude. Prayers are offered through Kamuy-Fuchi and through the outdoor nusa altars. The bear is shot with ceremonial arrows, then strangled between two logs — a death that leaves the body undamaged and the spirit free. Its blood is ceremonially drunk. Its flesh is cooked and shared as a meal of sacred food — the bear's parting gift to the humans it has lived among. The skull is mounted on a decorated pole at the nusa altar and addressed with further prayers: the spirit is formally sent home, laden with offerings and messages, with the request that Kim-un-Kamuy visit again.

The iomante was widely documented by Western and Japanese observers from the late nineteenth century onward, and it provoked both fascination and misunderstanding. Animal rights activists in the modern era have criticized the ceremony without engaging its theological premises. The Ainu perspective is not that the bear is killed as a sacrifice but that a divine guest is hosted, honored, and returned home with proper ceremony — and that the failure to perform this ceremony with care would be not cruelty to the bear but an insult to the kamuy that the bear embodies. The ceremony was formally banned by Japanese authorities in 1955 as part of the campaign against Ainu religious practice; it has been revived in symbolic form as part of the modern cultural revival, though the raising of live bears is no longer practiced.

VI. Oral Tradition — The Voice that Carries the World

The Ainu had no writing system of their own. The entire body of Ainu religious knowledge, cosmological teaching, genealogy, and practice was transmitted orally, through performance, across generations.

The primary literary form is the kamuy yukar — the "deity song" or "god-chant." These are extended first-person narratives spoken from the perspective of a kamuy, recounting the deity's adventures, encounters with humans, and place in the cosmic order. Some kamuy yukar run to seven thousand verses or more. They are performed at ceremonial gatherings, by trained singers whose role is part artistic and part spiritual: the performer becomes, in some sense, a vehicle for the kamuy's own voice. Yukie Chiri (1903–1922), a young Ainu woman who died at nineteen, produced the first major transcription and translation of kamuy yukar into Japanese in her anthology Ainu Shin'yōshū (1923) — a foundational act of preservation accomplished by an insider of extraordinary determination.

The yukar (hero songs) are similarly long narratives, but from the human perspective: the exploits of Ainu heroes (often the cultural hero Okikurmi, or Aioina) against monsters, rival peoples, and supernatural adversaries. The uepeker are shorter prose or poetic prose tales, more like conventional oral literature, covering a wider range of topics.

Together these genres constitute a sophisticated oral theology — a cosmological literature that encodes Ainu understandings of the relationship between humans and kamuy, the rules governing hunting, the proper conduct of ceremony, the nature of illness and healing, and the history of the Ainu people. They are simultaneously religious scripture, legal code, practical knowledge, and literary art.

The most significant early Western recorder of Ainu oral tradition and religious life was John Batchelor (1854–1944), an Anglican missionary who spent sixty-four years among the Ainu from 1877 onward. His The Ainu and Their Folk-Lore (London: Religious Tract Society, 1901) is the largest single English-language collection of Ainu religious material from the living tradition. It is available in the public domain on the Internet Archive. Batchelor brought to the work the strengths and limitations of his position: genuine linguistic competence, sympathetic attention, and the theological assumptions of a Victorian Anglican missionary. His descriptions of Ainu ceremony and cosmology are indispensable despite the interpretive framework he imposed.

VII. The Meiji Wound — Suppression and Dispossession

The history of Ainu religion in the modern era is a history of systematic destruction followed by incomplete and ongoing recovery.

Japanese expansion into Hokkaido accelerated dramatically in the Meiji period (1868–1912), as the newly consolidated nation-state pursued the settlement and development of what it called Ezochi — the "land of the barbarians." Ainu lands were designated as "ownerless" and transferred to the Japanese state. Ainu men were prohibited from hunting and fishing by traditional methods. Traditional tattoos, earrings, and clothing were banned. The Ainu language was forbidden in schools, and children were punished for speaking it.

In 1899, the Japanese government passed the Hokkaido Former Aborigines Protection Act. The law classified the Ainu as kyūdojin — "former aborigines" — a category designed to register their eventual disappearance through assimilation. It allocated small plots of agricultural land to Ainu families, but the plots were generally unsuitable for farming and reverted to the state if uncultivated within fifteen years. Its nominal "protection" masked a comprehensive program of dispossession, assimilation, and cultural erasure.

Religious prohibition was part of the program. The iomante was eventually formally banned in 1955. Traditional shamanism was discouraged. The ceremonies and cosmological knowledge that gave Ainu life its structure were driven underground — maintained by elders in private, concealed from Japanese officials, slowly lost as generations passed without transmission. The Ainu language, which carries the entire oral theological literature in its tonal patterns and ceremonial registers, contracted rapidly: from tens of thousands of speakers in the mid-nineteenth century to fewer than one hundred by the 1980s, and likely no fully native speakers today.

The 1899 Act was not repealed until 1997 — ninety-eight years after its passage. The replacement law, the Act for the Promotion of Ainu Culture and Dissemination and Enlightenment of Knowledge about Ainu Traditions, supported cultural activity but did not address land rights or explicitly recognize the Ainu as indigenous. That recognition came only with the 2019 Ainu Policy Promotion Act — the first piece of Japanese legislation to use the phrase "indigenous people" in reference to the Ainu.

VIII. Revival and the Living Tradition

The current condition of Ainu religion is one of partial recovery from near-total destruction — a recovery conducted under enormous constraints but with genuine energy.

The 1997 Cultural Promotion Act created a legal framework for public Ainu cultural activity that had not previously existed. Ainu associations in Hokkaido began offering language classes, workshops in traditional crafts (inau-making, weaving, embroidery), and public performances of traditional music and dance. The cultural revival proceeded in parallel with a growing political movement for Ainu recognition and rights.

On July 12, 2020, the National Ainu Museum — Upopoy in Ainu, meaning "singing in a large group" — opened at Shiraoi on the coast of Hokkaido. It is the largest museum dedicated to Ainu culture in the world, and its construction was accompanied by an outdoor experience space that reconstructs traditional Ainu village life. Upopoy is simultaneously a museum, a research center, and a gathering space — a place where contemporary Ainu people can encounter their own tradition through the institutional apparatus of the Japanese state that suppressed it. The relationship is complicated and recognized as such by Ainu commentators.

The revival of ceremonial practice is more contested than the revival of cultural performance. Ceremonies requiring specific knowledge, specific materials, and specific lineages of transmission cannot simply be reconstructed from ethnographic records. The kamuy yukar exist in written transcriptions but were performed in living voices; the performance tradition, once interrupted, is not easily restored. The iomante has been revived in symbolic forms that do not include the raising of live bears — a simplification that some community members accept as appropriate adaptation and others regard as a loss of theological core.

The religious revival is also taking place in a landscape where many Ainu people identify with Buddhist or Shinto traditions adopted during the centuries of Japanese assimilation, and some with Christianity through the Batchelor-era and subsequent missionary presence. The relationship between these adopted religious identities and the indigenous tradition is navigated individually: some contemporary Ainu practitioners see no contradiction, weaving together the traditions; others pursue a more reconstructionist return to pre-assimilation practice; others do not identify with the religious tradition at all.

What is beyond dispute is that the tradition is alive — not merely as museum object or tourist performance, but as spiritual practice engaged by living people who have chosen to maintain, revive, and transmit it. The kamuy are still present in the mountains and rivers and fires of Hokkaido. The question is whether there are enough people who know how to address them.

IX. Ainu Religion in the Living Traditions Frame

Ainu religion presents a different relationship to the Aquarian phenomenon than most communities in this archive. It is not a new religion born from the disenchantment of modernity; it is an old tradition that survived modernity's assault through suppression and concealment. It did not emerge from the collapse of institutional religion; it was the target of institutional religion's campaigns of destruction.

Yet the recovery of Ainu tradition in the late twentieth and early twenty-first century participates in a broader Aquarian dynamic. The same historical forces that produced New Age interest in indigenous wisdom traditions, that prompted Japanese practitioners to study Zen in American monasteries, that drove seekers across the world to look past their inherited institutional containers — these forces also created a context in which Ainu cultural and religious identity could be asserted and valued in ways that were not possible a generation earlier. The Upopoy museum exists in part because of a global shift in how indigenous traditions are regarded.

The Ainu case also illuminates, by contrast, what is distinctive about the Japanese new religions documented elsewhere in this archive. Tenrikyō, Ōmoto, Konkōkyō — these are traditions born from disenchantment, created by the shock of modernization and the failure of older containers. Ainu religion is a tradition predating that disenchantment, shaped by a relationship to the natural world that was never interrupted by the Reformation, the Enlightenment, or the Industrial Revolution — until it was violently interrupted by colonial suppression. The recovery of Ainu religion is therefore not quite a new religious movement and not quite a survival tradition: it is something in between, a tradition actively reconstructed in the aftermath of a rupture.

The comparison with Ryukyuan religion — the indigenous tradition of the Okinawan islands, also suppressed by Japanese expansion and also currently in a state of partial revival — is the most instructive within this archive. Both traditions are animist, both were driven underground by state campaigns of assimilation, and both are now being reclaimed by communities for whom the tradition represents not merely cultural heritage but spiritual identity. The Living Traditions archive holds both profiles side by side.
