The "Gujo Odori” festival is one of the three most famous traditional dance festivals in Japan. The town of Gujo-hachiman (Hachiman is a town in the center of Gujo district in Gifu prefecture) is surrounded by mountains and the Yoshida River. There is no other town where folk music is so popular. From early July to early September, there are many folklore events almost every night. Especially at Obon festival (a traditional summer festival in which the Japanese honor their ancestors) from August 13-16, the people dance all night. The sight of more than 20,000 people dancing together in a trancelike state is a real thrill of folklore.
The people of this region have a special love for horses, and the lords encouraged horsemanship and horse trading among its population. The tradition is still alive today. This dance mimics the movement of horses while riding.
