Osaka Aquarium Kaiyukan Complete Visitor Guide 2027: Whale Sharks, Osaka Bay and Tempozan Combo

Osaka Aquarium Kaiyukan — opened in 1990 and still a top-5 global aquarium by annual visitors — is built around a 9-metre-deep central tank holding two Rhincodon typus whale sharks, with 15 Pacific-rim exhibits spiralling from the top floor down. The design means visitors see each tank from both surface and depths.
