What this place is

The Osaka Aquarium Kaiyukan (海遊館, Kaiyūkan; known as the Kaiyukan) is an aquarium located in the ward of Minato in Osaka, Osaka Prefecture, Japan, near Osaka Bay. When it opened in 1990, it was the largest public aquarium in the world. The aquarium is a member of the Japanese Association of Zoos and Aquariums and is accredited as a Museum-equivalent facilities by the Museum Act from Ministry of Education, Culture, Sports, Science and Technology. The aquarium is about a five-minute walk from Osakako Station on the Osaka Municipal Subway Chūō Line, and is next to the Tempozan Ferris Wheel.

Why it is worth the trip

  • A main tank large enough to show schooling fish and big pelagics moving naturally.
  • Species collected from the surrounding sea, so the line-up differs from other Japanese aquariums.
  • Feeding times and training sessions where staff explain what the animals are doing and why.

What you can do here

  • Check the daily schedule on arrival and plan around feeding and show times.
  • Sit at the big tank for ten minutes — it is the one exhibit that rewards patience.
  • Visit the touch pool for starfish, urchins and rays, especially good with children.
  • Watch a dolphin or sea lion session; front rows may get wet, which is part of the fun.
