The world rests on the back of a giant fish

In short: For the Ainu people, the world is not a random accident of geology. It is a spiritual landscape where every object, animal, and mountain possesses a soul. From the creator who shaped the earth to the spirits who grant humans survival skills, life is a constant negotiation with the divine.

The Ainu worldview is rooted in animism, specifically the belief that everything in nature contains a 'ramat'—a sacred life force that is an extension of a 'kamuy' (spirit or god). Rather than being remote beings, kamuy opt to manifest within our realm via fleeting bodily shapes. When a vessel—be it a bear, a tool, or a mountain—is broken or dies, the ramat returns to the spiritual realm, leaving the physical remains as a gift for humans. This cycle of reciprocity dictates Ainu life: if humans treat these gifts with deep sincerity and gratitude, the kamuy will return out of delight.

This theology manifests in profound cultural practices like the 'Iyomante' bear-sending ritual. Dating back to 11 CE, the ritual involved raising bear cubs in villages as children, nursing them, and eventually ritually killing them to return their spirits to 'kamuy mosir' (the Land of the Gods). While outlawed in 1955 as animal cruelty, the ritual was exempted in 2007 for its cultural significance and has since evolved into an annual festival featuring torch parades and traditional dances. These dances, often involving large circles and mimicking animal movements, serve to reinforce the connection between the human and religious worlds.

The Ainu also maintain a complex geography of the divine. They view the world as a spherical ocean where the earth rests on the back of a large fish, whose movements cause earthquakes. They identify specific deities for different domains: Kim-un-kamuy (bears and mountains), Rep-un-kamuy (the sea), and Kotan-kar-kamuy (the creator). Furthermore, the goddess Kamuy-huci, associated with the hearth and fire, is central to healing rites. While modern surveys show a majority of Ainu now identify as Buddhist or non-religious, many continue to integrate traditional beliefs into daily life, maintaining a unique religious consciousness where both systems coexist.

Archaeological evidence from the 13th to 17th centuries supports these spiritual orientations, showing house alignments and burials that correspond to specific spiritual beliefs. For instance, at the Tohohata site, 75 burials were found with a southeast orientation near the Winter Solstice sunrise point. These physical remains confirm that Ainu spirituality was not just a collection of myths, but a spatial reality that dictated how they built their homes and laid their dead.
