Come to see the penguins waddle around the outside deck.
The first shallow aquarium in Japan(about 7㎡), a part of it is only 5cm deep. You can watch the penguins walking above your head.
The biggest overhead aquarium（about 80㎡） in Japan. Most of the indoor ceiling of the 1st floor is a underwater window, so many people can watch the penguins swmming and diving into the water at the same time. Since there is no roof on the pool，you can see the sky trough the water. When it‘s a nice weather, you can see the penguins just like flying in the sky!
