Furusutobaru Castle

Furusutobaru Castle (J: フルスト原城 Furusutobaru jō, O: フルスト原城 Furusutobaru gushiku) is a Ryūkyūan castle on Ishigaki Island in Ishigaki, Okinawa. It is a prime example of a Yaeyama castle.

History
It is unknown when the castle was built. It was the site of a battle between the forces of Oyake Akahachi and Nakasone Toyomiya during the former's famed 1500 rebellion. It has been debated whether this was Oyake's home, although the castle matches the description given in the Kyūyō, a history of the Ryūkyū Kingdom. In 1978 the site was designated a Prefectural Heritage Site.
