Irisuna-jima

Irisuna-jima (入砂島), also known as Idesuna-jima (出砂島), is an uninhabited island in Tonaki, Okinawa Prefecture, Japan. It lies approximately four kilometres to the west of Cape Watanjisaki (ワタンジ崎), the northwest tip of Tonaki Island. Ceramics, including kamui ware and celadons, are evidence of human activity on the island over the longue durée. Public access is now prohibited since, under the designation FAC (Facilities Admin Code) 6078, Idesuna Jima Range (出砂島射爆撃場) is a live-fire training area for the United States Forces Japan.
