According to legend, Amawari was born to a peasant family in Yara, in Chatan magiri.
Three years later, Shō Hō was named Prince of Nakagusuku and given Nakagusuku magiri as his domain.
So Shō Ken became the Heir apparent of the kingdom, and was given Kume and Nakagusuku magiri as his domain.
In 1645, his domain was changed to that of Nakagusuku magiri, and his title to Prince of Nakagusuku.
