Shōsatto

Shōsatto, also read Ufusatu, founded Sannan (Nanzan), the southernmost of Okinawa's Three Kingdoms, in 1337. He had been aji of Ōzato and set his capital at Shimasoe-Ōzato Castle. The Ming Veritable Records record his tribute mission to China in 1383, and in 1385 the Hongwu Emperor invested him as King of Sannan with a gilded silver seal.

His kingdom soon came apart: in 1392 Shō Hashi of Sashiki seized his capital and he withdrew to Shimajiri-Ōzato. One account says that around 1396 his uncle Ō Eishi, allied with Hashi, defeated him and he fled.

Korean records tell of a Sannan king who fled to Korea in 1398; some take him for Shōsatto, though others think him another lord.
