The Osaka Kaiyukan Aquarium is one of the world’s greatest aquariums. It is home to some of the world’s rarest species, not rare as in endangered, just very difficult to spot due to their habitat. Marine animals such as Whale Sharks, the Japanese Salamander, snow crabs and so much more. 

The main exhibits at the Kaiyukan all come from around the Pacific Ring of Fire. In total, over 600 species, and some 30,000 animals call the Osaka Kaiyukan their home.   

The Aquarium is outfitted with pretty much everything, from a Japanese forest exhibit with otters, an entire room full of dozens of different jelly fish species, a great barrier reef area, a touch tank with nurse sharks and rays, penguins, seals, crabs, eels and so much more. We purposely left out pictures of actual exhibits so that you will be thoroughly impressed when you visit for yourself.

The Pacific Ocean enclosure is without a doubt the main attraction, which has a 9m depth, with a length of 34 meters.  The viewing area for the pacific ocean exhibit extends roughly 3 stories in height, all with large glass windows that provide perfect viewing into the enclosure which hosts some 30 unique species and a couple whale sharks. The glass to this enclosure his enormous, with a thickness of 30cm, preventing over 5400 tons of water from spilling out.
