Morioka Sansa Odori Festival, held from August 1 through 4, is one of the Five Great Festivals of Tohoku. Over 10,000 taiko drummers and dancers parade through the city; Sansa is listed in the Guinness Book of Records as the largest taiko drum festival in the world. Legend has it that Sansa dance began when a wicked demon was punished by the god of Mitsuishi Shrine. The god made the demon swear that he would never do bad deeds again, and as a sign of his pledge, the demon placed his hand on a large rock and left a hand print. The locals rejoiced, dancing around the rock. This story explains the origin of Sansa, as well as the name “Iwate,” which means “rock hand.” The choreography for the main Sansa Odori parade on Chuodori Street is modern and simplified, but you can also see traditional and more dynamic Sansa dances at other venues such as Ekimae Hiroba in front of the station and at various halls.
