Osaki Town, in the eastern Osumi Peninsula, faces Shibushi Bay. It has Yokose Kofun (an ancient burial mound), a national Historic Site, and the area was anciently called Kuni. The coastal pine forest Kuni no Matsubara lines the shore, and waste sorting gives the town a high recycling rate. Its autumn-winter daikon radish production ranks 6th in Japan.
