Otaru Aquarium

Otaru Aquarium is a public aquarium on Hokkaido's coast that houses around 250 marine species in tanks filled with natural seawater from the Sea of Japan. The facility features specialized areas for different marine creatures and offers a comprehensive look at the local ocean environment.

This aquarium was founded in 1959 as one of the first public facilities of its kind in Hokkaido. Over the decades, it has steadily grown its collection and become a major institution for marine education in the region.

Daily performances with seals, dolphins, and penguins showcase a Japanese tradition of careful animal training and entertainment. These shows form a central part of the visitor experience and reflect local values that emphasize precision and connection with marine life.

A dedicated bus service runs from Otaru Station directly to the aquarium, with combination tickets available that bundle transportation and entry. Visit during quieter times to enjoy the exhibits without crowds.

This facility houses Japan's only captive harbor porpoise, kept in a specialized tank with natural seawater conditions. This rare animal makes it a special place where visitors can observe a species that normally stays far offshore and out of view.
