Kasai Rinkai Aquarium Free Entrance Day

Celebrating the 26th anniversary of its opening back in 1989, the Kasai Rinkai Aquarium again invites you to experience the world of sea creatures free of charge. Hit hard by the mysterious mass deaths of its tuna population earlier this year, the facility, which is also known as Tokyo Sea Life Park, is surely looking to use this special occasion as a turning point for the better. October 10 is also 'Tuna Day', so be sure to check out the giant tuna tank and its new inhabitants, in addition to the over 600 other marine species featured here.
