Irisuna-jima

Irisuna-jima, also known as Idesuna-jima, is an uninhabited island in Tonaki, Okinawa Prefecture, Japan. It lies approximately four kilometres to the west of Cape Watanjisaki, 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 6078, Idesuna Jima Range is a live-fire training area for the United States Forces Japan. ()
