At some point late in the 15th century, the nearby Miyako Islands were divided between two influential families, the Nakasone and Kaneshigawa, who were fighting one another for dominance of the area.
However, Nakasone Toyomiya led a counterattack against Akahachi, overwhelming his forces and moving on to attack Yonaguni Island as well.
Akahachi led the people of Ishigaki and the surrounding islands in revolt against the kingdom, refusing to pay taxes or tribute.
After Nakasone conquered Yaeyama, a force of roughly 3,000 Ryukyuan troops was sent by King Shō Shin in 1500, and the rebellion was suppressed with the annexation of the Sakishima Islands.
[3] While official records and histories produced by the Ryukyu Kingdom label Oyake Akahachi as a rebel and a traitor, locally on Ishigaki and the surrounding islands he is known as a hero who sought to secure their freedom and independence.
