SUMIDA, Acquarium

The Aquarium, inaugurated in May 2012, is one of the main attractions in Sumida. Although of modest size, it is home to over 10,000 sea creatures, and is located on floors 5 and 6 of the Tokyo Solamachi, a shopping complex at the base of the Tokyo SkyTree.

There is no standard visitor route, and you can make your way around the aquarium as you please.

The central feature of the Sumida Aquarium is the 350,000-liter tank, the largest indoor tank in Japan, which is home to dozens of penguins and seals. The glass walls are so thick that they require no additional supports, so that visitors can admire the creatures from virtually any angle. The design of the tank allows you to get right up close to them, thanks to the walkways and other structures positioned above the surface of the water.

The various areas of the aquarium include The Shimmering Water, which recreates a natural marine environment: here you can even observe the tiny bubbles of oxygen that form on the surface of the aquatic plants, thanks to photosynthesis, which allow the fish, shrimps and micro-organisms to breathe....
