Aqua World Oarai, the aquarium at Oarai, displays roughly 580 species of marine life across its exhibits, with a particular focus that has made it one of Japan’s leading facilities for shark and ocean sunfish (mola mola) displays. Large tanks recreate the Pacific and Kashima-nada ecosystems found just offshore, and the aquarium’s oceanfront location, a short distance from the iconic Oarai torii gate, makes it easy to combine with the area’s other coastal sights.
