Satto (察度) (1321 – November 17, 1395) was King of Chūzan. He is the first ruler of Okinawa Island who was recorded by contemporary sources. His reign was marked by expansion and development of Chūzan's trade relations with other states, and the beginning of Okinawa's tributary relations with Ming dynasty China, a relationship that continued for roughly five hundred years, almost until the fall of the Qing dynasty.
