Shō Hashi
The king had a "kara-naa" and used it in diplomatic correspondence with China. The royal "shii" Shō (尚) was, according to Ryukyuan records, given to Shō Hashi by the Xuande Emperor of Ming China. This statement is highly questionable because no such record is found in Chinese documents and Shō Hashi used the "shii" even earlier. In 1692, the branch families of the royal house were given the "shii" Shō (向, note the different kanji) and the "nanui-gashira" Chō (朝) no matter how distant from the king.
