Taromai (他魯毎), read variously as Tarumoi and Tarumī, was a local ruler of Okinawa Island, who was given the title of King of Sannan.
This report was highly unusual because Okinawans routinely deceived the Chinese into thinking that the throne was normally succeeded from the father to the son.
Historian Dana Masayuki raises the possibility that it was a cover story for Taromai's illegitimate seizure of power.
[3] Historian Wada Hisanori notes that the Rekidai Hōan contains diplomatic documents supposedly sent by Taromai, King of Sannan.
Wada speculates that Shō Hashi, the unifier of Okinawa Island, had already kept Sannan under his control.
Shō Hashi finally overthrew the King of Sanhoku in 1422, unifying Okinawa Island.
