Nakagusuku Castle Okinawa, Japan

View of the first citadel. Nakagusuku was built c. 1450, and destroyed 1458. The lord of the castle, Gosamaru, was falsely accused by the rebel Amawari of complicity in Amawari's rebellion. Gosamaru committed suicide, and his castle - the largest in Okinawa - was destroyed.

Okinawan stonework, as seen in this photo, was more advanced than Japanese at this time.
