Hokuzan

Hokuzan was the northernmost of Okinawa's three kingdoms, based at Nakijin Castle on the Motobu Peninsula. In 1337 its lord was Haniji, the first Hokuzan ruler named in Chinese records.

After Chūzan entered Ming tribute relations in 1372, Hokuzan gained the same trading status, but sent only nine missions to China in thirty years. In 1416 three anji lords defected to Chūzan; Nakijin fell after a fierce defence, its king killed himself, and Shō Hashi annexed Hokuzan.
