It is said that Akahachi was born on
Hateruma Island, and that he was large and physically strong even as a child. He moved to
Ishigaki Island as a young adult, and became the chief of Ōhama Village (today part of Ishigaki City) soon afterward. His influence soon extended over all of Ishigaki Island, and beyond, to other islands in the
Yaeyama Islands group. 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. Seeking to take advantage of the chaos and disunity, Akahachi proposed an invasion of the Miyako Islands. However,
Nakasone Toyomiya led a counterattack against Akahachi, overwhelming his forces and moving on to attack
Yonaguni Island as well. In the late 15th century, the
Ryukyu 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. Akahachi led the people of Ishigaki and the surrounding islands in revolt against the kingdom, refusing to pay taxes or tribute for three years. After Nakasone conquered Yaeyama, a force of roughly 3,000 Ryukyuan troops was sent by King
Shō Shin in 1500. The 46 ships were divided into two units, one attacking Tono Castle and the other attacking Shinkawa. The Ryukyuan army attacked relentlessly and captured Akahachi, who was later executed. Finnaly, the rebellion was suppressed with the annexation of the
Sakishima Islands by Ryukyu. ==Legacy==
