Churaumi, Okinawa

Water for the ocean exhibits at the Churaumi Aquarium in Okinawa is pumped from the sea to create an authentic environment for the marine inhabitants inside this Ocean Expo Park attraction. The headlining display at Churaumi is the massive, 2-million-gallon Kuroshio Sea tank with manta rays, including a few that have been born in the aquarium, and whale sharks, one of the rarest species aquarium visitors will ever see. Churaumi's Coral Sea exhibit receives direct sunlight so that the coral is able to grow just as it would in the wild.
