Uozu Aquarium
A municipal aquarium in Uozu City, Toyama Prefecture, founded in 1913. It is known as the oldest existing aquarium in Japan. Inside, the exhibits focus on creatures that live in the rivers and seas of Toyama Prefecture, with more than 10,000 animals from Approx. 330 species on display. The highlight is the 4-meter-deep large Toyama Bay tank, where you can watch schools of large fish from Toyama Bay, including yellowtail and longtooth grouper, swimming together.
It’s a small, cute aquarium, not one of those huge, super dramatic ones. The place isn’t very big, so you can probably see everything in a little over an hour. Great for a casual stop if you’re already in the area.
