The Ainu are the Indigenous people of Hokkaido, the Kuril Islands, and Sakhalin, with a distinct language, culture, and spiritual traditions separate from mainstream Japanese culture. Upopoy is Japan's first national facility dedicated to preserving and promoting Ainu heritage, opened in 2020 following official government recognition of the Ainu as Indigenous people in 2019. The facility plays a crucial role in cultural revitalization efforts and educating the public about Ainu history and traditions.
