Hakkeijima is an artificial island off the Kanazawa district of southern Yokohama, joined to the mainland by a bridge. The island itself is free to walk around, and on a sunny day the promenade, lawns and sea views are enough for a cheap afternoon. You only pay for what you go into.

The aquariums are the main draw. Aqua Museum, the largest, holds around 700 species and 120,000 animals, with a school of about 50,000 sardines and the Animal Life Live! dolphin and sea-animal show. Dolphin Fantasy, Fureai Lagoon and Umi Farm are smaller and more hands-on. In the Pleasure Land ride area, the Surf Coaster Leviathan swings out over the sea, and part of the area reopened on 1 August 2026 as OTO-RACTION PARK, where SONIC TUNE! and ROCKY EAGLE pick music with AI based on your mood.

The One Day Pass covers the four aquariums and the rides; the Aqua Resorts Pass is aquariums only. Weekends in summer are crowded, and the island is exposed, so bring a layer on windy days.
