Sumida Aquarium is an indoor aquarium in Tokyo Skytree Town Solamachi that can be visited together with Tokyo Skytree, where visitors see penguins, jellyfish, and fur seals. The jellyfish exhibit stands out, and the layout lets visitors view penguins up close. It has tanks for penguins and tanks for sharks and rays, and it can be viewed comfortably indoors. The interior is small and the number of displayed creatures is low, so the visit can be finished in 30 minutes.
