Largest aquarium in Japan
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. The number of visitors reached 50 million on February 26, 2008. Achievement in 6317 days (about 18 years) is the fastest among aquariums in Japan, and about 60% of the visitors are repeaters. In 2014, the total number of visitors exceeded 65 million. A ceremony was held in 2024 to celebrate the achievement of 85 million total visitors.

Visitors will go up to the eighth floor on the escalator, passing through the Aqua Gate, a tunnel tank with various tropical fish. After exiting the escalator is the Japan Forest, which recreates a Japanese forest and holds Asian small clawed otters, Japanese giant salamanders, black crowned night herons and many other native freshwater animals. The walk through aquarium displays marine life in several habitats comprising 27 tanks in 16 main exhibits with a total volume of 10,941 tons of water. The habitats are from the Ring of Fire area of the Pacific Ocean and these include the Aleutian Islands (tufted puffins), Monterey Bay (California sea lions and largha seals), Gulf of Panama (ring tailed coati, long spine porcupinefish and blotcheye soldierfish), Ecuador Rain Forest (arapaima, red bellied piranhas, capybara & green iguanas), Antarctica (Adélie, gentoo & king penguins), Tasman Sea (Pacific white sided dolphins) and Great Barrier Reef (palette surgeonfish, pennant coralfish & threadfin butterflyfish), Seto Inland Sea (common octopus, Japanese spiny lobster & red seabream), Coast of Chile (Japanese anchovies and South American pilchards), Cook Sea Strait (loggerhead sea turtles, deepwater burrfish & scarlet wrasse), Japan Deeps (Japanese spider crabs, elephant fish & Hilgendorf's saucord) and a jellyfish gallery (moon jellyfish & northern sea nettle). The Aqua Gate at the entrance and the Jellyfish corner are new facilities built in 1998. The "New Interactive Area" that opened in 2013 allows visitors to see the animals up close and possibly touch them. In the "New Interactive Area", 3 zones are constructed, the Arctic Zone, in which visitors see ringed seals, Falkland Islands Zone, where they can see southern rockhopper penguins, and the Maldives Zone, in which they can directly touch stingrays and small sharks like brownbanded bamboo sharks and coral catsharks. In 2020, the museum shop was reopened on February 22 after renewal work was carried out to coincide with the 30th anniversary of its opening. The music used at Kaiyukan changes with the time of day, but these are all from the "Acoustic Cafe Underwater Walk" album.

Osaka Aquarium are focusing on research on sharks and Rays. In addition, the past eight surveys of tagging whale sharks have revealed that they can migrate to the Philippines and dive to a depth of

The aquarium has been breeding and studying Giant Devil Rays since 2008. We are very focused on giant devil ray research and are conducting captive research with the cooperation of local fishermen at our Research center "OBIC" devil rays were trained for health management for transportation to the Pacific Tank, and a large 8 meter diameter tank was set up on the deck of the ship,
The giant devil rays were transported over a long distance from Kochi Prefecture to Osaka under conditions that allowed them to swim freely. At the aquarium, giant devil rays became pregnant in 2022. It was the first time in the world that a giant devil ray was conceived in captivity. After the pregnancy was discovered, regular ultrasound examinations were used to check the growth of the fetus and to record changes in the mother's abdomen bulge and behavior. In addition, to protect the baby after birth, a partition net was set up in the tank in preparation for the birth. The baby was born on the morning of May 16, and although the birth was celebrated with great fanfare, the puppies soon died. They swam unsteadily and weakly and died at 16:18. Based on the results of the pathological autopsy and blood tests, the cause of death was considered to be. It was due to an imbalance of blood due to physical exhaustion from not being able to swim. In addition, since the opening of the Osaka Aquarium, it has succeeded in breeding Spotted Seal, Pelagic stingray, California Sealion, Sea otter, etc., and received the breeding award from the Japanese Association of Zoos and Aquariums.

Osaka Aquarium Kaiyukan has a research center "Osaka Aquarium Biological Research Institute of Iburi Center (OBIC)" in Iburi, Kochi Prefecture, where fish swimming tests and animals to be brought in are carried out in tanks with a water volume of and a water volume of although it was not exhibited at the aquarium, they succeeded in captivity of Pelagic thresher for 26 days at the offshore fish farms in Iburi, Kochi Prefecture.

The Osaka Aquarium Kaiyukan's conceptual design, architecture, and exhibit design was led by Peter Chermayeff of Peter Chermayeff LLC while at Cambridge Seven Associates. Visitors first take an escalator up to the 8th floor, and then go down a corridor to the 4th floor. The first three floors are machine rooms containing filtration equipment and are not open to the public.
