Nakasone Toyomiya

Nakasone Toyomiya Genga (仲宗根豊見親玄雅^?, Okinawan: Nakasone Tuyumya Genga) (active c. 1500-1530) was a Ryūkyūan Chieftain and later Anji of the Miyako Islands credited with repelling an invasion from Ishigaki Island, and expanding Miyako political control over some of the Yaeyama Islands. When the Miyako Islands were attacked by the Ryūkyū Kingdom, Nakasone saved the people of Miyako from harm by agreeing to surrender to annexation by the Kingdom.

Nakasone was the great-great-grandson of Meguro Mori who, in the 14th century, defeated the Yonahabara army under Sata Ubunto to unite the Miyako Islands for the first time.

Toyomiya (or, Tuyumya in Okinawan) was not a name, but rather something akin to a title or honorific. While he passed on the family name Nakasone to his descendants, this lineage, of which he is the founder, is at the same time called the Chūdō family (忠導氏, Chūdō-uji^?). While the exact year of Nakasone's birth is unknown, the family's records indicate that he was born sometime in the Tianshun Chinese Imperial era, i.e. 1457-1464.

At this time, the Ryūkyū Kingdom, based at Shuri on Okinawa Island, did not yet have direct control over the Yaeyama or Miyako Islands, but merely expected tribute to be paid. In 1500, Oyake Akahachi of Ishigaki Island led the people of Ishigaki and the surrounding islands in revolt against paying tribute and against the Kingdom. Nakasone's family was entrenched in a power struggle with their rival the Kaneshigawa family for control of Miyako, and Oyake planned to invade the island during the division. Upon learning this, Nakasone led a preemptive invasion of the Yaeyama Islands, securing his status as leader of Miyako, and seizing Ishigaki, Yonaguni (where he took the daughter of the chieftain Untura as his prize), and a few other neighboring islands in the process.
