Uozu Aquarium, Public aquarium in Uozu, Japan.
Uozu Aquarium is a public facility in Uozu featuring around 200 marine species with interactive displays. Its signature feature is an acrylic tunnel where visitors walk through while observing fish swimming around them.
The facility opened in 1913 as Japan's first aquarium on the Sea of Japan coast, marking a major achievement in aquarium history. Subsequent renovations modernized the displays and expanded its collections over the decades.
The facility focuses on studying deep-sea creatures and bioluminescent organisms that live in local waters, helping visitors understand the special marine life of the Pacific region.
The aquarium sits within a city park and is easy to reach by car or bus, with ample parking for both vehicles and groups. Plan to spend at least two to three hours here to see the exhibits without rushing.
The facility pioneered an innovative tunnel design with acrylic walls that let visitors walk surrounded by water and fish. This concept later inspired similar designs in aquariums around the world.
