One of the famous historical figures of Miyako is Nakasone-tuyumiya, who unified Miyako and the seven outlying islands during the latter half of the 15th century. His large stone tomb is located on the north side of Hirara Port.

At eighteen years of age, Nakasone-tuyumiya defeated many rival chieftains and brought all the Miyako Islands under his control. The exact date of his birth is not known, but he is believed to have been born between 1458 and 1464 and to have lived more than 70 years. His virtues, adventures, and accomplishments are told in many local stories and songs. He is credited with establishing the formal tributary relationship between the Miyako Islands and the royal court in Shuri, building bridges and warehouses, drilling wells and improving irrigation, and paving the way for a religiously directed community in Miyako.

During his rule, he successfully overcame an uprising led by Oyake Akahachi of Yaeyama in 1500, and 22 years later defeated another rebellion by Onitora of Yonaguni. One of the stories about this legendary ruler describes him as a man of extraordinary bravery and guile, somewhat like Odysseus in the Homerian epic.

His unique tomb has been designated an Important Cultural Asset and has been placed under the custody of the prefectural governmentfs Cultural Property Protection Committee.
