Otaru Aquarium is located in Shukutsu, Otaru City, Hokkaido, and specializes in showcasing the marine life of the Hokkaido region. The aquarium focuses on fish and marine organisms that thrive in cold-water environments. With its expansive grounds and naturalistic exhibit design, visitors can experience a deep connection to the sea.
The facility is operated by the Otaru Aquarium Public Corporation. For many years, it has played a vital role in communicating the charm and importance of Hokkaido's oceans. The institution is dedicated to the management of biological species and ongoing activities to educate the public about the local natural environment.

The main building features 62 tanks filled with fish native to Hokkaido and other cold-water regions. Notable exhibits include sea turtles and the famous 'sea angel' (Clione). There are also specialized areas featuring large tanks with sharks and rays. The main building is a reinforced concrete structure consisting of one basement level and two floors above ground.
The aquarium typically operates from mid-March to late November. Because the behavior of the animals and the surrounding environment changes with the seasons, you can experience different facets of the marine world depending on when you visit. Since operating hours and seasonal schedules can fluctuate, we highly recommend checking the official website before your visit.

Visitors can observe the natural behaviors of various marine species throughout the facility. In addition to the main building, the complex includes the Kaiju Park and the Seal Stadium, where different types of animals are showcased. Exploring these various areas provides a comprehensive understanding of the biodiversity found in Hokkaido's seas.
The facility offers ample parking with space for approximately 1,000 vehicles. Within the premises, you will find rest areas, souvenir shops, and restaurants, making it easy to enjoy a meal during your stay. Nearby, you can also find other local attractions such as the Otaru Shukutsu Marine Land amusement area.
Temperatures inside the aquarium can vary depending on the season and weather outside, so please dress comfortably for your visit. For accessibility, the facility offers rental services for strollers and wheelchairs. While service dogs and guide dogs are permitted, please note that general pets are not allowed inside the premises.
