Okinawa's largest theme park promotes the region's history, culture, and natural sciences with a variety of attractions, including Gyokusendo Cave, which you can walk through in about 30 minutes along an 890m (2,900-ft.) walkway suspended above water and filled with impressive stalagmite and stalactite formations; a museum devoted to the habu, Okinawa's indigenous poisonous snake; an orchard of 450 tropical fruit trees; an outdoor plaza for performances of the local Eisa dance; and workshops for potters, glass blowers, weavers, and other artisans housed in restored century-old Okinawan homes. Plan on 3 hours to see everything.
