Namahage masks are traditionally carved from willow, cedar, or chestnut wood.
The ritual is traditionally performed on New Year's Eve to warn against laziness and pray for a bountiful harvest.
There are over 60 distinct variations of Namahage mask styles found across the Oga Peninsula.
Namahage wear 'mino' (straw capes) that are believed to lose their protective powers if the straw falls off during the visit.
The ritual involves loud, rhythmic shouting of 'Naku ko wa inega' (Are there any crying children?).
The Oga Namahage tradition was designated a UNESCO Intangible Cultural Heritage in 2018.
The Namahage Museum focuses on the cultural heritage of the Namahage, a traditional Oga Peninsula ritual involving masked demons visiting local homes. The main exhibition hall displays over 150 unique wooden masks, each handcrafted by residents of different villages across Oga. Visitors can participate in a simulated Namahage ritual experience that mimics the traditional New Year's Eve custom. The facility is situated adjacent to the Oga Shinzan Folklore Museum, which features a historic thatched-roof farmhouse for authentic reenactments. The Namahage tradition is recognized as an Intangible Cultural Heritage by UNESCO. Exhibits detail the specific variations in mask design and costume materials, such as straw capes, across various regional districts. The museum complex serves as a primary educational hub for understanding the Oga Peninsula's animistic roots and folk beliefs.
