Traditional Ainu Religion

The Ainu are the indigenous people of Hokkaido in northern Japan, and of Sakhalin and the Kurile Islands, with a distinct language, culture, and religion that persisted largely outside the mainstream of Japanese civilization until aggressive assimilation policies in the nineteenth and twentieth centuries. Their cosmology is one of the great animist traditions of East Asia, and their afterlife concept is tightly bound to their understanding of the world as populated by kamuy — spirits that inhabit animals, plants, objects, and natural phenomena, each with its own home realm and its own relationship to humans. The Ainu universe is built of three layers. Kanna Kamuy Moshir, the upper world of the sky kamuy. Ainu Moshir, the human world (literally "the world of humans"). Pokna Moshir, the lower world, not a hell but another land, where some kamuy and some of the dead reside. The layers are connected by rivers, by mountains, by specific sacred trees. Travel between them is possible for kamuy, for shamans, and for souls at death. Every significant animal is a kamuy in disguise — a spirit who has taken animal form in order to visit the human world, bringing its flesh and fur as a gift to the humans who hunt it. The central religious obligation of the Ainu is to treat these visiting kamuy with the respect due to guests who have brought gifts. The iyomante, the bear-sending ceremony, is the most famous expression of this. A bear cub is raised by a village for one to two years, treated as a beloved family member, then ritually killed with elaborate reverence, its spirit sent home to the mountains with gifts, messages to the bear kamuy community, and the promise that the village will welcome bears who come again. The ceremony is not barbaric by Ainu understanding; it is precisely the opposite — the respectful conclusion of a visit in which both parties have done what they came to do. At death, the human soul travels to Pokna Moshir. The journey follows a river downward. Proper burial matters — the body is dressed in traveling clothes, personal possessions are placed in the grave broken or with holes punched through them so their spirits can travel with the dead to the underworld, food is provided for the trip. If all is done well, the soul arrives in the kamuy realm, joins its ancestors, and may eventually return to the human world through rebirth in its own lineage. Children born after a beloved elder has died may be recognized as that elder returning. Improperly buried or wronged souls may become tusu, restless spirits, and return to the village to cause illness or misfortune. Shamans (tusu kur) can identify these cases through trance and ritual, and can negotiate the spirit's onward journey. The shaman's work across the three layers — communicating with the kamuy of the upper world, serving the community of the middle world, escorting the dead to the lower world — is central to Ainu religious life. What distinguishes Ainu eschatology is the radical continuity it asserts between humans, animals, spirits, and the landscape. The afterlife is not an elsewhere. It is another part of the same network. A bear sent back to the mountain and a grandmother sent to Pokna Moshir are doing the same thing: returning to their kamuy home, carrying the gifts and messages that their visit to the human world has generated, waiting for the next occasion when the relationship will bring them back again.
