About

Iwashimizu Matsuri is the most important of the more than 100 rites held each year at Iwashimizu Hachimangu, and one of Japan's three great imperial festivals held in the ancient manner, alongside Kyoto's Aoi Matsuri and Nara's Kasuga Matsuri. An envoy of the Emperor attends and presents offerings. The festival began in 863 as a ceremony of releasing living fish and birds, praying for the peace and happiness of all living things. In the dead of night on September 15, three sacred palanquins carrying the deities descend from the main hall on Mt. Otokoyama to the hall at its foot, lit only by torches and lanterns and escorted by about 500 attendants. The offering rite takes place as day begins to break, fish and birds are released at the Hojo River, and the palanquins return to the mountaintop in the evening.
