Asamushi Aquarium is the home of over 10,000 aquatic animals with around 400 rare species from Aomori and around the world. One of the main attractions is the large saltwater tank featuring a 15-meter (49 feet) long viewing tunnel (15 meters wide, 4 meters deep). Walking through the tunnel gives visitors the feeling of walking under the ocean as schools of fish swim above and around. In addition to the dolphin show which runs all year round, visitors can enjoy watching sea lions, penguins, and seals up close in the Kaijukan (Marine Animal Hall). In the Petting Area, visitors can also experience touching various marine animals.
