The extremely modern area around the port boasts many attractions, one of which is the Osaka Aquarium Kaiyukan. An armada of uniformed hostesses greets you at the entrance of the aquarium, which is dedicated to the marine world of the Pacific. The colossal whale shark steals the show, but there are also sea otters, a huge moonfish and emperor penguins, to name but a few. Kaiyukan is one of the world's largest aquariums, with a main pool of 5 400m³, a capacity of 11 000t of water, and a collection of around 580 aquatic species.
