Sorakin, the Sky Aquarium of Gold Tower

Sorakin, the Sky Aquarium atop Gold Tower in Utazu, combines panoramic views of the Seto Inland Sea with a surprisingly charming collection of fish tanks housed inside the 158-meter-high observation tower. The upper floors feature themed aquarium displays with tropical fish, jellyfish, and local Seto Inland Sea species, while the glass-walled observation deck offers sweeping views across the islands and the Great Seto Bridge. Lower floors cater to families with arcades, bowling lanes, and play areas, making it a full day's entertainment for children. The combination of aquarium, observation deck, and amusement facilities in a single tower is uniquely Shikoku, and sunset views from the upper floors are particularly striking.
