A major figure of the Gushikawa family, he was appointed jitô (steward) of Nakijin magiri at some point between 1488-1505, and came to be known as "Prince Nakijin." For about seven generations from then, he and his descendants served as Hokuzan kanshu ("Warden of the North"); this lasted until 1665, when his descendants moved to Shuri.
Shô Shôi is entombed in the West Chamber of the royal mausoleum, Tamaudun.
