Tokyo Sea Life Park opens its doors for a special Free Admission Day, offering a chance to explore one of Tokyo’s most thoughtfully designed aquariums at no cost. Located beside Tokyo Bay in Kasai Rinkai Park, the facility is known for its iconic glass dome and its massive circular tuna tank, where bluefin tuna swim continuously in a powerful current.

Visitors can also see one of Japan’s largest penguin enclosures, featuring multiple species in a naturalistic coastal habitat, along with jellyfish, coral reef fish and deep-sea creatures. With a strong focus on marine conservation and education, it is an ideal outing for families, ocean enthusiasts and anyone curious about life beneath the waves.
