The Kaiyukan in Osaka is the largest aquarium in Japan and at the same time one of the largest in the world. It is located in the Minato district near the port area of Osaka. Opened in 1990, it is one of the largest indoor aquariums with a total water volume of more than 11,000 tons is home to around 620 animal and plant species.
Timed tickets are required for entry currently in order to limit the number of guests per hour.
The main theme of the aquarium is the "Ring of Life" or the "Ring of Fire" and is represented by the arrangement of the more than 15 different pools. Each of the pools represents a specific region on the Pacific Ring of Fire and visitors can experience themed worlds on a tour from the Japanese forests to the Antarctic to the heart of the aquarium, the Pacific Ocean. In the latter, for example, there is a whale shark, the largest fish on earth.
In addition to these permanent exhibitions, the Kaiyukan also offers some interactive highlights, where you can get close to different animal species and sometimes stroke and even feed them. The aquarium has a souvenir shop and is located directly at Tempozan Harbor Village, a shopping and entertainment complex with many restaurants and shops.
Travel from the 8th floor down to the 4th all while gazing as these majestic and serene creatures swim alongside other marine life in their collosal tank. The Kaiyukan has one of the world’s largest manmade habitats for whale sharks and the cylindrical tank ensures that you’ll see their every angle.
In the Maldives area of the Osaka Kaiyukan you can experience touching some incredible species of sharks and rays. Compare the texture of the rough sharkskin to that of the smooth ray. Will you be brave enough to reach down and touch these majestic animals?
Experience a new whole of marine life and romance during the mysterious night aquarium. Every night from 5 pm until close the lights are dimmed and the aquarium takes on an otherworldly quality as the animals show their nighttime behavior and begin to fall asleep. Let their sleepy world lull you into a calm unlike any other.
At the nearby Tempozan Harbor Village right outside of Kaiyukan, you can see even more interesting things, like Legoland Discovery Center Osaka; the Tempozan Marketplace with its various shops; or Naniwa Kuishinbo Yokocho, an eatery with local specialties as well as well-loved staples. Then take a 15-minute ride on the Tempozan Giant Ferris Wheel, one of the largest in the world.
