The main attraction of the Notojima Aquarium is the whale shark. Despite being the largest fish in the world, this gentle giant is popular for its calm and relaxed swimming style. As soon as you enter the aquarium, you'll be greeted by the main exhibit, the "World of Blue," a huge tank where the whale shark resides. The exhibit is unique in that it features a gentle slope that allows you to slowly descend into the fantastical blue water and observe the swimming fish from various angles. Starting from a position where you can peek into the water's surface, you may be lucky enough to see the whale shark swimming just below. You can enjoy the sensation of diving into the blue world while observing the powerful whale shark from different angles.
