There is a small, small aquarium in the Tokyo Tower, actually.
You may not find it because in the first place you will never thought about going aquarium while you are at Tokyo Tower.
However, I don’ t know why but there is also an aquarium at SKY TREE….
Anyways, this samll aquarium could be the hiding place from the commotion. And there are not so many people even on weekends. Good place to take your kids or kill time!
