The Namahage Sedo Festival has its roots in the folklore of the Oga Peninsula in Akita Prefecture. The festival centers around the Namahage, demonlike ogres who visit households during winter to punish those who are lazy or disobedient, especially children and young wives. This tradition has been passed down for generations and is closely tied to the Shinto ritual of Saitousai.

Its cultural significance was recognized internationally when the Namahage were added to UNESCO’s Intangible Cultural Heritage of Humanity list in 2018. This recognition highlights the festival’s unique blend of religious ritual, folklore, and community celebration.
Namahage are seen as both gods and ogres: gods because they are linked to Shinto shrines and are believed to bless the community with bountiful harvests, and ogres because their fearsome appearance encourages good behavior. Some legends even suggest that Namahage originated from China, reflecting the long history of cultural exchange in the region.
The Namahage Sedo Festival 2026 will take place from Friday, February 13 to Sunday, February 15 at Shinzan Shrine in Oga, Akita Prefecture. The festival is one of Japan’s most unique winter events, attracting visitors from across the country and abroad.
