Kaiyukan is a large aquarium in Tempozan Harbor Village.
It is at the mouth of Aji River and is located about 1 km south of Universal Studios Japan.

"U" in the word is pronounced long, so it is read as "Kaiyûkan".

This aquarium was opened in 1990.

This is one of the largest aquariums in the world.
Especially, the largest fish tank holds 5,400 cubic meters.
