Yoron Castle Ruins

Tradition says the third son of the Hokuzan king crossed to Yoron and began this castle around 1405, and that work stopped when Hokuzan fell to the Chūzan king in 1416, so it was never finished. Islanders call him Ōshan. The west side uses natural cliffs as walls, and stone walls run some 200 m from the north round to the south-east in a line said to trace a crouching dragon. The grounds now hold the Tokonushi and Kotohira shrines and a tomb attributed to Ōshan.

Three times a year, on lunar 15th nights, the Yoron Jugoya Odori dances are performed in the shrine grounds, one set in Yamato style and one in Ryukyu style, a national important intangible folk cultural property. The town designated the site in 1976, and the national government followed on 10 March 2025.
