30-Second Answer

Japan is world-class for both aquarium count and quality. Churaumi in Okinawa stars whale sharks and giant mantas, Osaka Kaiyukan recreates the Pacific in its central tank, and Yokohama Hakkeijima pairs an aquarium with a theme park. Sumida Aquarium (Tokyo) and Nagoya Port Aquarium are convenient backup plans for rainy days.
