This elementary school closed and was remodeled into an aquarium! Since this fantastic idea came to be in April of last year, a hundred thousand visitors came to see the closed-school-turned-aquarium in the first six months! The students of the old school once used the pool where there are now sharks, the vaulting horse with goldfish inside, the fountains where there are now "petting pools" where you can touch the sea cucumber, starfish, shrimp, and more. It's funny to see how they use expressions like "attendance" and "class dismissed" around the aquarium.
The information about all the creatures isn't just written in simple English translations. It was translated by students studying Japanese at a university in Hawaii so that even children can easily understand everything. They've really put a lot of thought into accommodating their foreign guests. https://visitkochijapan.com/en/see-and-do/10005
