About

Yokohama Hakkeijima Sea Paradise is one of the greater Tokyo area's most beloved family destinations, blending a spectacular marine-life aquarium with an amusement park on its own private island in Yokohama. Opened in 1993, the resort has grown into a full-day experience that easily keeps families entertained from morning to evening, with enough variety to satisfy toddlers and teens alike.

The aquarium (Aqua Museum) is the crown jewel, housing thousands of sea creatures including dolphins, beluga whales, sharks, and penguins. Live shows run throughout the day, and the interactive touch tanks let younger kids get hands-on with starfish and rays. For families who want more speed, the amusement park side delivers roller coasters, a massive Ferris wheel, and water rides that soak riders — bring a change of clothes.

The island setting makes the whole experience feel like a resort escape, with waterfront views at every turn. Combination passports covering both the aquarium and rides offer the best value, and weekday visits dramatically reduce wait times. With nursing facilities, family restrooms, and multiple dining options, Hakkeijima Sea Paradise handles the logistics of a family day trip with ease.

It is about 40 minutes from Yokohama Station by the Seaside Line monorail.
