The Hachidairyu Shrine, located in Onoshimo in Taimei town, is an old shrine that is cherished in the community as 'Hachirosan'. The shrine is said to have been built in 964 by the Lord of Ono, Kunitaka Nori, The Hachidai-Ryuou Shrine in Ounoshimo Town has eight “hokora” (lesser shrines) enshrining 8 different dragon gods. The shrine is known as ‘Hachiros san’ by its parishioners and the ‘Hachidai - Ryuou’ (Eight dragon gods) have long been venerated as rain making deities. An annual dance takes place at the shrine, and this began as a ritual farmers practiced to pray for rain. The origins go back to the beginning of the Edo period (1603-1868) when the Tomoda and Ikusue river valleys were turned into farmland in civil engineering projects attributed to the Daimyo, Kato Kiyomasa. However, the new agricultural land area did not have good access to water, and when there were water shortages farmers held rituals to pray for rain. After WWII, with the construction of reservoirs and waterways, there was much less need to pray for water for agriculture, but in order to preserve the traditional culture of the region the annual event has continued.
