尚巴志王
According to the "Chūzan Seikan" (1650), the unnamed King of Sannan lost popular support. Shō Hashi, then the Aji of Sashiki, overthrew the King of Sannan and became King of Sannan himself. The King of Sannan then replaced Bunei as King of Chūzan in 1421. Shō Hashi finally overthrew the King of Sanhoku in 1422, unifying Okinawa Island. The "Chūzan Seikan" did not date Shō Hashi's overthrow of the King of Sannan. Sai Taku's edition of the "Chūzan Seifu" (1701) generally followed the "Chūzan Seikan".
