The most impressive aquarium I've ever been to. Way better than Sydney or Kuala Lumpur anyway. However, the whale shark is a pelagic species, and having 2 of them in a tank, does not sit well with me. Their tank here is absolutely huge in our terms, but not for these gentle giants. This fish can live to over 100 years in their own habitat but don't last long in the few tanks scattered around the world. The record is one living 26 years (Okinawa) in captivity, so it's obviously not good for them. It's a dream of mine to dive with these docile creatures, but I never thought I would see these in a tank first. The rest of the aquarium is really top notch and a great day out. The way it's structured, so some tanks traverse multiple floors, is class. Its great watching seals and dolphins rapidly torpedo down through the depths. There were many species from the Sea of Japan and more tropical Pacific waters, that I would never have had the opportunity to see before. Such as the white sided dolphins and Japanese tufted puffins, which are more quirkier than their cousins from Ireland. There were also many species of sharks and rays here, too numerous to count. I could have watched the manta rays and great scalloped hammerhead sharks all day long. The mola mola (ocean sunfish) is a big attraction here because you don't really see them in many aquariums. I saw one while diving in Australia before and they leave a lasting impression on you because they look so bizarre. We felt sorry for it here, because it looked so lonely. The specialist penguin and jellyfish exhibits here were also brilliant. It's not only Japanese marine life here but they have exhibits from many regions of the world. I would advise buying a ticket online in advance because it gets quite busy here. There is a large gift shop at the end, ideal from bringing stuff home. Aside from the whale sharks, I absolutely loved it here!
