- Japanese: 與那覇世頭豊見親 (Yonahasedo Tuyumya)
Yonahasedo Tuyumya was a late 14th to early 15th century Miyako Island elite.
When he traveled to Okinawa Island to bring Miyako's tribute to the Chûzan court in 1390, he encountered difficulties communicating with the Okinawan elites, who did not understand his Miyako language. Thus, he had some twenty Miyako Islanders remain on Okinawa to study Okinawan language.
A stone stele recording these events, and related later events down to the 18th century, long stood at Tomari udun.
