This is been the best aquarium I've ever visited. There is an impressive 4-story main pool with a whale shark (the star of the aquarium), jellyfish and giant crabs from Japan. As a sort of curious note, there's a section dedicated to sharks with a life-sized artificial great white with its cage and all, just for a laugh. The store is very Japanese of course, with stuffed animals of all the animals in the aquarium! It's really worth seeing!
