The Oi Shrine Grand Festival is also called the "Obi Festival" and is a festival in which the god of Oi Shrine returns to the old shrine site (inn) once every three years. Today, for three days including the second Sunday in October, a gorgeous festival is held in the town of Shimada where dainu, daimyo processions, Kashima odori, street stall dances from 1st Avenue to 5th Avenue, and ground dances are held. Especially on the last day, all of them form a large procession together with the mikoshi procession, and they slowly parade for a whole day for a round trip of about 4 km from Oi Shrine to the inn. Due to the appearance and swing of the dainu at this time, as well as the unique form of Kashima Odori, the obi festival has come to be counted as one of the three strange festival in Japan. In addition, since the Edo period, first-class entertainers from Edo have been invited to choreographed dances in each town, Nagauta, and shamisen, and Nagauta in particular is also called "Nagauta Festival" because the iemoto of each school competed for throat.
