Osaka Aquarium Kaiyukan Complete Visitor Guide 2027: Whale Sharks, Osaka Bay and Tempozan Combo
2027-02-27 ยท 9 min read
Kaiyukan is one of the largest public aquariums in the world โ eight stories tall, built around a 5,400-tonne Pacific Ocean tank with two 7-metre whale sharks, and still the only aquarium in Japan where the walkway spirals from the top down.
Osaka Aquarium Kaiyukan โ opened in 1990 and still a top-5 global aquarium by annual visitors โ 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.
