🐡About the Aquarium 🦈

The Osaka Aquarium Kaiyukan features 15 exhibits that simulate different aquatic animals and habitats from around the world. Some of these exhibits include the Pacific Ocean, the Great Barrier Reef, the Aleutian Islands, and the Japan Forest. Each exhibit is designed to provide visitors with an immersive experience of various marine environments.

The aquarium is home to a diverse range of marine life, including various species of fish, sharks, rays, jelly fish, sea otters, penguins, and more. The number of fish species may vary, but at the time of my last update, the Osaka Aquarium Kaiyukan was known to house over 30,000 marine creatures representing around 620 species.

The aquarium has many tanks, each showing animals from a different part of the Pacific Ocean. The biggest tank is in the center, representing the Pacific Ocean itself. The main tank is 9 meters or about 30 feet deep with 5,400 cubic meters of water and it’s where you can see the main attraction – a whale shark!

When you start your visit on the eighth floor, you go down one floor at a time in a spiral around one of the world’s big central tanks. Some tanks even go across a few floors, so you can watch the animals from different levels and angles.🐙

🐠 Other stand-out sealife include manta rays in the central tank and dozens of jellyfish species. 🦑

Suggested Time 🐬

1.5 – 2 hours is plenty of time.

It was a great experience, and you certainly do not need the whole day here. You can easily spend 2-4 hours here to check off a few bucket list things in the area like the observatory Cosmo tower or Ferris wheel.

Suggestions before you go 🐠

You do not need to buy tickets ahead of time but you can online.

Take a blank notebook for stamps! In Japan, stamps are in many places for tourists to have as a souvenir and it is fun to collect. I forgot my book, and there were tons of stamps throughout the aquarium such as whale sharks, penguins, and seals.

Hours of Operation and Ticket costs


The time differs on the day. Typically 10:00 to 20:00 (entry until 19:00).

Admission Fees

¥2,700 for adults aged 16 and over
¥2,300 for seniors
¥1,400 for children aged 7-15
¥700 for children aged 3-6
FREE for children under 2 years old


After entering the huge fish tank tunnel, you begin making your way up the escalator or elevator to the 8th floor where you start at the Japan Forest Zone which is amazing, and where you meet the otters! Then you make your way down each floor by ramp taking you through various and intelligently placed exhibits.

  • Shark Species from the Pacific Ocean

  • Jellyfish exhibit with dozens of species

  • Vocal penguins species from Antarctica

  • Curious Dolphins

  • Two Whale sharks

You get to be face-to-face with the world’s biggest shark, the whale shark, at different depths of the tank as you circle down the Pacific Rim exhibit from many floors.

The hammerhead sharks and stingrays are memorable because of how big they are and how intrigued they are by spectators.
