Okinawa Prefecture consists of more than 150 islands in the East China Sea between Taiwan and Honshu. Known for its tropical climate, vast beaches and coral reefs, and World War II battlefields. Okinawa’s largest island, Okinawa Island, is home to the Okinawa Prefectural Peace Memorial Museum, which was built to convey the 1945 massive invasion of the Allied Forces to the future generations, and the Okinawa Churaumi Aquarium with whale sharks and manta rays.
