"Arch tank" that reproduces a state closer to the natural sea.
The sunlight shines in, the scenery of coral reefs is reproduced in the blue sea and white sand, and dolphins and colorful fish swim.
You can feel as if you are taking a walk under the sea, watching dolphins swimming, jumping, and swarms of fish swimming from the sea.
In addition, there is no roof above the aquarium, and on a clear day the shimmering sunshine sways,
Countless ripples spread on the water surface on a rainy day, and the water surface sways on a windy day, allowing you to enjoy various fantastic scenes of nature.
