At the Katsuura Underwater Park Center, you can enjoy a realistic underwater world as if you were in an aquarium from the underwater observation tower. The view from the 24.4m height is a must-see, overlooking the mysterious scenery of creatures and beautiful white sandy bottoms that change depending on the season and transparency. There is also a unique system where the fee varies depending on the transparency. It's worth visiting even if you have to go up and down 96 steps!
