Aqua World Oarai is a large aquarium located in Oarai, Ibaraki Prefecture, that takes advantage of its location facing the Pacific Ocean to offer attractive marine life exhibits and hands-on programs. It is particularly known for the large number and variety of shark exhibits it houses, and also serves as a marine education center for the region through its educational commentary and efforts in raising and breeding sharks. The aquarium is home to a wide variety of ecological exhibits, centered around a large aquarium, and can be enjoyed by a wide range of people, from families to animal lovers and groups looking to learn about nature.
