A festival in which locals dress up as demons and scare the bejesus out of young children. There are also bonfires, a dramatic explanation of the reason for the festival, taiko drumming and mochi hurling.
While you’re in town, take a look at the Nahagekan (Namahage museum). The museum is open year round and is dedicated to the festival for which it is named. Inside you can see the various costumes and masks and even try them on. Admission to the museum is ¥500 or ¥800 with a combined ticket to the neighbouring Oga Shinzan Folklore Museum.
