Ōzato

Ōzato lies in the southern part of Okinawa, a land once contested by local lords and the kings of Nanzan. Their strongholds, known as gusuku, rose on defensible heights above the surrounding countryside. In 1429 Shō Hashi of Chūzan attacked the Nanzan stronghold of Shimajiri Ōzato and defeated its ruler, Tarumii. The victory brought the island's three rival kingdoms together under the Ryūkyū Kingdom.
