There is an aquarium in Kagoshima.
It is called Io World.
Io means fish in Kagoshima direct.
A Whale Shark is there.
At outside of the aquarium, there is a Dolphin canal and you can watch where dolphins are swimming and a mini show is free.
It was nice.
But it is closed now for maintenance work on the Dolphin canal.
I think it will open again soon.
