Maxell Aqua Park Shinagawa

Maxell Aqua Park Shinagawa is one of Tokyo's most visually spectacular aquariums, combining traditional marine exhibits with cutting-edge LED light art installations. Located inside the Shinagawa Prince Hotel, it is fully indoors and climate-controlled, making it a great choice rain or shine. The park is divided into themed zones — from a serene jellyfish section with floor-to-ceiling tanks to a lively performance pool where dolphins and sea lions put on dazzling shows with synchronized music and lights.

Kids are captivated by the manta ray touch pool, the walk-through shark tunnel, and a magical carousel surrounded by glowing sea creatures. At night, the entire park transforms with immersive projection mapping across the water tanks, turning fish into living art. The aquarium also has a Ferris wheel-style sea sphere and interactive zones where children can learn about ocean ecosystems through touchscreens and hands-on exhibits.

Stroller access throughout, nursing rooms, and multiple dining spots inside the hotel make logistics smooth for families. Plan to arrive early on weekends — the dolphin show fills up fast. The evening light show is worth staying for if you have tweens or teens who might find a daytime-only visit too short.
