Furyumen is a mask looking like a demon which a kakeuchi (dancer) wears in “Men Buryu (masked dance)” practiced in Kashima City, Saga Pref. This dance is designated as an important intangible folk cultural asset of the prefecture. “Men Buryu” dance is a kind of ritual performing art that is dedicated to pray for abundant harvest and rainfall. The dancer, wearing Furyumen over the face and Shaguma (a wig of long horse hair usually made of wool or hemp) on the head and dangling a small drum from the neck, dance fiercely to the sounds of Japanese flutes, drums, and gongs. The dancers, bravely raising their arms and legs, look really gallant. There are two kinds of Furyumen masks; a male mask and a female mask. A male mask has large eyes, firmly pursed lips, vertical wrinkles on the forehead, and a pair of long horns on the head. A male mask, on the contrary, has a wide opened mouth with a tongue reached out, slant eyes, and short horns. These horrible looking Furyumen masks are made out of camphor trees, paulownia, Japanese cypress, or a local species of Nogomi cedar, which are carefully selected by a mask carver. The mask carver then uses a traditional chisel and carves the wood with special attention to details.
