Ashizuri Underwater Observation Tower

The tower, located inside Ashizuri-Uwakai National Park, is a huge 24-meter-tall observation tower standing in the water which is one of the clearest offshore areas in Shikoku. Inside the tower are an observation room above sea level and an underwater observation chamber from which visitors can see tropical fish gathering near the 7-meter-deep ocean floor and schools of fish that change in variety from season to season. Girella, porcupine fish and butterfly fish can be seen from the underwater observation room throughout the year. Visitors may be able to observe mass migrations of sardines and horse mackerels in winter through spring and a migration of barracudas in autumn as well as sea turtles and rays.
