Overview of Ainu religion
The Ainu religion is the traditional spiritual system of the Ainu, the Indigenous people of Hokkaido, Sakhalin and the Kuril Islands. It centers on kamuy, divine beings who reside in the world of the gods but visit the human world in forms such as animals, plants, fire, water and natural phenomena. The bear, the owl, the orca and the fire goddess Kamuy Fuchi are among the most honored. Humans and kamuy are bound by relationships of mutual respect and exchange.
In Ainu thought, people show gratitude to kamuy through prayers and offerings, especially inau, wooden sticks carved with curled shavings, and through sake or millet. In return, the kamuy provide food, protection and blessings. Rituals called kamuy nomi involve prayers at the hearth, the center of the home. Rich oral literature, including epic songs called yukar, preserves myths of creation, culture heroes such as Okikurmi and stories told by the kamuy themselves.
Ainu culture suffered greatly from assimilation policies after Japan annexed Hokkaido in the nineteenth century, and many rituals were suppressed. Japan recognized the Ainu as an Indigenous people in 2008 and passed new legislation in 2019. Today revival efforts are strong, and travelers can learn about Ainu spirituality at Upopoy, the National Ainu Museum in Shiraoi, and at Ainu villages such as Akan Ainu Kotan and Nibutani, where artisans and storytellers share their heritage.
