Satto

Satto (r. 1350 to 1395) was a 14th-century king of the Okinawan kingdom of Chūzan. The first Okinawan ruler mentioned in Chinese sources, Satto accepted tributary status to Ming China, for which he was given lucrative trade license and declared the King of Ryukyu. He likely controlled only a small portion of central Okinawa, including his capitals of Urasoe and Shuri, and the main port of Naha. In the traditional histories of the Ryukyu Kingdom, he is described as the successor to King Seii, and as a virtuous ruler who later became decadent. He established the temple of Gokoku-ji and may have begun construction on Shuri Castle. His son Bunei took the throne after his death and was later overthrown by the First Shō dynasty.
