A traditional event of the Nishimonai area of Ugo Town, Akita Prefecture. It is said that these dances, which have been handed down from generation to generation for over 700 years, were performed to pray for abundant harvests and commemorate fallen feudal lords. Some dancers wear woven hats and Hanui costumes sewn from many different scraps of silk, while others are clothed in indigo-dyed yukata (summer kimono) with black hikosan-zukin (hoods) to hide their faces.
