The different views from the 7 viewing spots, which faithfully recreate the changing facets of the sea, are sure to arouse visitors’ curiosity.


Recreating an undersea sanctuary with around 500 tons of water
The Main Pool is filled with highly unique marine life including the white-spotted eagle ray, thornhead, green sea turtle, and pitted stingray. Seven viewing spots have been set up to fully capture the individuality of each species and the biodiversity of Japan’s seas. Enjoy the kaleidoscopic appearance of the sea from various locations. Filled with an immense amount of water—around 500 tons—the Main Pool gives visitors the illusion of being surrounded by pristine waters in an undersea sanctuary, providing peace of mind.
