Japanese Oni Exchange Museum

This is one of the world's few demon-themed museums. The museum is located at the foot of the Oe Mountain range, where many legends of Onis remain, including those of Shuten-doji. The giant onigawara (Japanese gargoyle) in front of the museum is the largest in Japan, standing 5 meters tall and weighing 10 tons, and has become the symbol of the museum.

The Mt. Oe is home to three Oni legends: the Oni extermination of Prince Hikoimasu, Emperor Sujin's younger brother; the Oni extermination of Prince Maroko, Shotoku Taishi's younger brother; and the legend of Shuten-doji; and the museum displays materials and masks from these legends. The exhibition "Nihon no Oni" (Japanese Demons) depicts Onis in a variety of contexts, including Onis in shrines, Onis in everyday life, Onis in Setsubun, and Onis in folk performing arts.

In the display of "Onigawara no Utsurikawari," visitors can trace the evolution of people's feelings toward Onis through onigawaras, which keep Onis out of buildings. Masks and other objects that people feared in other countries are introduced in the "Sekai no Oni” (Demons of the World) section. Works by people who have confronted their inner Onis are on display in the "Koryu Hall” (Exchange Hall).
