Fusutobaru-tsuku is said to be the residence of Oyake Akahachi, although there is no evidence of this link, and its origins are obscure.

Akahachi was from the neighbouring island of Hateruma, and through strength and charisma, he managed to convince the other chieftains and lords of the Yaeyama Islands to follow him, then declared that Yaeyama would not pay mercilessly heavy tribute to the Ryukyu Kingdom.

[2] When this news came to Naha, the court commanded the ruler of Miyako Island, Nakasone Toyomiya to invade and suppress of Yaeyama.

[2] Akahachi was killed, and Nakasone would go on to conquer the rest of Yaeyama and then submitted them to King Shō Shin.

[3] Finds include local pottery, white porcelain and celadon from China, and the bones of horses and cows.
