Tokyo Sea Life Park (Kasai Rinkai Suizokukan) is a massive aquarium in the south east of Tokyo notable for its doughnut shaped main tank featuring blue fin tuna that encircles the whole main complex. It is family-orientated, which is reflected in its very reasonable entry fees.
Tokyo Sea Life Park presents a huge variety of global sealife in natural settings. However the superstars of the show are tuna – blue fin tuna – which for most people probably conjure up nothing more dramatic than tin cans on supermarket shelves. But far from it. These fish are majestic, silver, perfectly streamlined machines on a mission.
They swim with powerful, effortless sways of the tail, each completely self-contained, uncurious about any other, but in an eerie unison, round and round – and fast! The blue fin tuna is a big fish with lines that evolution has honed to efficient perfection. They are impossible to simply glance at in passing. (You will be hooked.)
Besides the giant doughnut tank, the rest of the aquarium comprises scores of different shapes and sizes of tanks from “living room size” for tiny seahorses and other marine minutiae up to tanks big and comfortable enough for sharks.
Sea life is represented from all over the globe: the Pacific, the Atlantic, the Indian Ocean, the Caribbean, and the polar oceans – as well as fish that migrate across and between oceans, like tuna, hammerheads and rays.
There are also exhibits based on microenvironment, such as the deep sea, the shore line (feel free to touch), kelp forests, around Tokyo, and fresh water. Even water birds are represented (including puffins).
Having said that the blue fin tuna are the stars of the show, they get serious competition from the penguins in their outside pool, especially at feeding time.
