尚泰王
A set of "warabi-naa" appeared in the very beginning of recorded history and has not been changed since then. The number of "warabi-naa" pooled in society was extremely small. It was not uncommon for a "warabi-naa" to be shared by more than one person in a household. The first male child was usually named after his paternal grandfather. For example, the last king Shō Tai had the "warabi-naa" Umi-jiraa-gani (思次良金), which was also the name of his grandfather Shō Kō.
