Osaka Aquarium Kaiyukan is located in Tempozan Harbor Village which is close by Osaka Bay. It is one of the world’s largest aquariums, and certainly the most impressive aquarium in Japan. Because the Osaka Aquarium Kaiyukan is so big, you should give yourself at least two hours to walk through the many marine habitats that house charismatic animals like manta rays, otters, penguins and sharks!

Enter the aquarium through the underwater tunnel of the Aqua Gate!
The aquarium is organized into 15 zones which represent different environments around the Pacific Rim and houses 30,000 animals representing 620 different species. The 15 zones are arranged in a descending spiral that starts with the “Japan Forest” area and descends down to the “Pacific Ocean” level where you can view a huge 9 meter deep, and 34 meter long fish tank which is home to a variety of species including the world’s largest fish, the whale shark.

In general the aquarium does a very good job in recreating environments in which the animals can feel comfortable and this makes for a very educational experience for visitors of all ages.
