The main feature of the aquarium is that its inhabitants live in ultra-pure water that has passed through the center's filtration systems. In four display tanks, you can see typical representatives of the Tama River fauna: minnows, grayling, and sculpins swim here. This allows visitors to see in detail the creatures that are often difficult to spot in their natural environment due to the current.
In addition to meeting the fish, guests can head up to the observation deck, which offers a panoramic view of the surrounding area. Tamagawa-Fureai Aquarium is an intimate and educational spot, perfect for a family visit or for anyone interested in ecology and environmental protection.
