Osaka Aquarium (Kaiyukan)
The focus of Osaka’s Aquarium is some of the world’s largest fish tanks, home to whale sharks, rays and myriad fast-moving other fish.
Only a thin sheet of glass separates visitors from the denizens of the deep, displayed in 15 exhibits focusing on different ocean environments, and in particular the Pan Pacific Volcanic Zone.
From sand-scuttling spider crabs to jellyfish, otters, seals, dolphins and penguins, the aquarium captures the variety and fascination of the big blue.
Osaka Aquarium is in the Tempozan Harbor Village in the west of Osaka, a five-minute walk from Osakako subway station.
