Osaka Aquarium Kaiyukan (海遊館) is one of the largest public aquariums in the world. The aquarium is home to a large variety of aquatic life, including manta rays and whale sharks. The habitats are from the Ring of Fire.
After entering the building, there is a large “Aqua Gate” water tank to greet visitors as they enter the aquarium. Guests then proceed up the escalators to the “Japan Forest,” which focuses on sea otters and other land and sea based creatures. From there, if tourists proceed down the recommended pathway, they head down a spiral slope passing all of the main tanks on the path. Some of the tanks include seals, penguins, dolphins, tortoises, jelly fish, and in the largest tank houses the aquariums prized whale shark and manta rays. For tourists who cannot read Japanese, there are also audio guides available for rent to hear details about all the exhibits as you walk through.
The aquarium also hosts an ocean-view restaurant and gift shop. The hours are usually from 10 AM to 8 PM. The cost of entry for an adult is 2,300 yen and the aquarium is about a five-minute walk from the Osakako Subway station.
