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.

Enjoy Sea Paradise by night!

Enjoy Sea Paradise by night!

In the evening-only show, “The Color of Love”, projection mapping and the synchronized acrobatics of our dolphins come together for a magical performance. With the concept of the color of love, the show presents the subtlety of blues, the passion of reds, and the elegance of yellows before weaving them all together through the fantastical moves of the dolphins as messengers of love.

There is also the popular seasonal fireworks show, “Fireworks Symphony”. Gorgeous, colorful fireworks displays that match both the season and the accompanying music light up the night. As the fireworks are launched from the island’s wave breakers, this is a firework display where you can get a perfect, up-close view. Come and enjoy Japanese fireworks at Sea Paradise.
