Osaka Aquarium Kaiyukan

Kaiyukan is a world-class urban aquarium located in Minato Ward, Osaka, and is known for its exhibits that faithfully recreate the natural environments of the world’s largest ocean, the Pacific, and its surrounding regions. The core themes of the aquarium are the “Pacific Ring of Fire” and the “Ring of Life,” allowing visitors to feel the interconnectedness of life on Earth and the preciousness of living things.

Exhibit Features
The aquarium is designed as if visitors were traveling around the Pacific Ocean, with 14 major tanks and several special exhibit tanks arranged in geographical order. Guests begin in the “Japanese Forest,” then move around the “Pacific” tank as the centerpiece, experiencing environments from North America, South America, Australia, Antarctica, Southeast Asia, and more in sequence.

Pacific Tank
At the center of the facility is the विशाल “Pacific” tank, which is 9 meters deep, up to 34 meters long, and holds approximately 5,400 tons of water. Here, whale sharks (subject to change depending on exhibit status), manta rays, hammerhead sharks, bigeye trevally, and other species swim gracefully, captivating many visitors with their impressive presence.

Japanese Forest
This area recreates a lush natural environment with flowing waterfalls and moss-covered scenery, introducing creatures that live in mountain streams. It also depicts a hypothetical scene of “what if otters still lived in Japan,” creating a space that evokes both the beauty and fragility of Japanese nature.

Jellyfish Galaxy
A fantastical area focused on the beauty of jellyfish, where visitors can watch them drift gently as if floating through a galaxy. Thoughtful lighting and presentation create a serene and mysterious atmosphere.

Concept and Philosophy
Kaiyukan’s guiding philosophy is based on the idea that:

“The Earth and all living things on it form a single living organism that interacts with one another.”

Whether plants or animals, all life coexists within the Earth’s vast ecosystem, and the sea plays an especially important role in it. Based on this理念, Kaiyukan conveys to visitors the importance of “loving the sea, cherishing it, and passing it on to the future.”

Facilities and Access
Kaiyukan is conveniently located about a 5-minute walk from Osakako Station on the Osaka Metro Chuo Line. The facility is barrier-free and accessible for wheelchairs and strollers. It is popular with a wide range of visitors, from families with small children to couples and people interested in nature and living creatures.

Kaiyukan is not simply a place to “see” animals; it is a valuable place where visitors can deeply experience the origins of the Earth and the preciousness of life. Through its realistically recreated environments of the Pacific Rim and the sight of more than 620 species and over 30,000 animals, visitors can reflect on the mystery of life and the richness of our planet.
