Onna is one of Okinawa’s popular resort destinations, right on the East China Sea. The blue water and white sand beaches make this area great for relaxing resorts like the Renaissance Okinawa Resort, the Rizzan Sea-Park Hotel, Sunmarina Hotel and the ANA InterContinental Manza Hotel & Resort. Onna’s coastline is a great place to see seascapes from Cape Manza and Cape Maeda, as well as offering great snorkeling and diving opportunities at the Blue Cave.
