The themes of the aquarium are Sagami Bay and the Pacific Ocean, the multitude of creatures that live there, and the interconnectedness of life. Visitors can have fun in the aquarium while learning about the ocean and its surroundings.

Upon entering Enoshima Aquarium, visitors will see exhibits focusing on Sagami Bay, followed by the deep sea, jellyfish, and marine animals. The aquarium also offers various explanations, shows, and programs that allow visitors to interact with marine creatures. Visitors are encouraged to experience “surprise and excitement” and “healing” through these activities. In addition, attractive seasonal exhibits and temporary events are also held.
