Hakone-en Aquarium

Western Area2h


This aquarium opened in 1979 is the second highest aquarium in Japan. Hakone-en Aquarium consists of both fresh-water and salt water sections, and “Baikal Seal Square” displays over 32,000 sea and fresh-water creatures from 450 species. You can’t underestimate an aquarium on a mountain-top, as it features a sunken vessel in the massive 7 meter-deep tank with 1,255 tons of water, large sharks and penguins among other creatures. It takes advantage of the cool climate of the high elevation to keep many Baikal seals in an outside pool. Visitors can enjoy a unique charm that is different from other aquariums.
