Iyomante

Iyomante is a central ceremony of Ainu religion, the indigenous religion of the Ainu people of Hokkaido, Sakhalin and the Kuril Islands, built on the belief that certain animals, above all the bear, are kamuy, divine or spiritual beings, who visit the human world temporarily wearing an animal form as a kind of gift, bringing meat, fur and other resources for the community's benefit before their spirit returns to the world of the kamuy.

In the ceremony's traditional pattern, a bear cub was raised within the community, sometimes for a year or more, nursed and cared for as something closer to a family member than livestock, before being ritually killed in a manner and with accompanying prayers, offerings and formal address understood as sending the kamuy's spirit home with honour, gratitude and requests that it return again bearing further gifts, followed by a feast shared among the community. The rite is best understood in the terms Ainu tradition itself uses, as sending home a divine guest rather than as simple hunting or sacrifice in the sense those words carry outside the Ainu religious framework, and the atlas describes here the ceremony's meaning, structure and history rather than its specific ritual procedure, which belongs to Ainu religious knowledge.

Iyomante and Ainu religious and cultural practice more broadly came under sustained pressure during Japan's modern assimilation policies, particularly following the 1899 Hokkaido Former Aborigines Protection Act, which pushed Ainu communities toward Japanese language, agriculture and custom and treated indigenous Ainu practice as an obstacle to be overcome rather than a tradition to be respected, a documented history of state suppression that closely parallels the treatment of indigenous religious practice by settler states elsewhere in the world.

Iyomante in its traditional bear raising form became rare through the twentieth century, and by recent decades is performed only occasionally, chiefly as a deliberate act of cultural preservation and revival by Ainu organisations and communities working to sustain a heritage that came close to being lost outright, rather than as the regular ceremonial practice it once was across Ainu settlements. Japan formally recognised the Ainu as an indigenous people only in 2008, and further legislation in 2019 acknowledged Ainu cultural and linguistic rights more fully, a late and still incomplete national reckoning that Ainu cultural organisations continue to press further, with ceremonies including iyomante, performed in careful, deliberately non-exploitative and community-led settings, forming part of the wider contemporary effort to keep Ainu religious tradition genuinely alive rather than reduced to a museum exhibit.
