Ocean Expo Park is a massive coastal recreational facility in Motobu, Okinawa, originally constructed to host the 1975 International Ocean Exposition. The park serves as the home of the Okinawa Churaumi Aquarium, which is world-renowned for its massive Kuroshio Sea tank. The grounds include the Tropical Dream Center, featuring greenhouses with thousands of orchids and a 36-meter observation tower. Visitors have access to Emerald Beach, a Y-shaped coral sand beach characterized by its distinct turquoise water. The park hosts the Native Okinawan Village, a collection of reconstructed traditional island dwellings from the 17th to 19th centuries. Botanical offerings include the Tropical & Subtropical Arboretum, which displays native flora of the Ryukyu Islands. The park spans a large coastal area on the Motobu Peninsula, offering integrated pathways between its aquarium, gardens, and seaside zones.
