About Sea Paradise

Covering an entire island, one of Japan’s biggest theme parks!
Yokohama Hakkeijima Sea Paradise, located in the city of Yokohama’s Kanazawa Ward area of Yokohama Bay, covers an entire island of approx. 24 hectares. The sea, island and living creatures that characterize the ocean leisure park come together in the only park of its kind in the metropolitan area—one that covers an entire island. The park combines aquariums, a theme park, a shopping area, restaurants and a hotel. Since its opening on May 8, 1993, local people, people from the metropolitan area, and more recently foreign visitors, have flocked to Yokohama Hakkeijima Sea Paradise.
Easy access from Tokyo and local tourist spots.
It only takes around an hour from Tokyo tourist destinations like Asakusa, Shinjuku and the Tokyo Station area, and only around half an hour from the Yokohama Bay Area, Kamakura or Enoshima. Yokohama Hakkeijima Sea Paradise is the only leisure island that allows visitors to experience the seas of Japan, an island, and various living creatures so close to the heart of the city.
