Shinagawa Aquarium offers full-scale displays of more than 450 species throughout its 25 areas. Its giant tanks with see-through undersea tunnels is a must-see attraction. Walking through the glass tunnels, you can get a close look at 1,500 fish and more. It makes you feel like you’re walking on the ocean floor as you see countless species swim past you, such as groupers, sea breams, sharks, turtles, giant rays and seals. It is an amazing and surreal experience!
