Take a plunge into the wonders of the underwater world at Hakone-en Aquarium. Let playful Baikal seals and over 30,000 other graceful and fascinating marine animals keep you enraptured for hours!
Experience life underwater on the shores of Lake Ashinoko! Home to more than 32,000 sea and freshwater creatures of 450 species, Hakone-en Aquarium will take you on a magical tour through the world’s oceans and rivers. Its exhibits are split into three main zones: the Baikal Seal Plaza, the Seawater Pavilion, and the Freshwater Pavilion. At Baikal Seal Plaza, you can observe Baikal seals — one of the world’s smallest seals, and the only one to live completely freshwater — from an observation deck. As the highest aquarium in Japan, its elevation allows it to take advantage of the cool climate to house the seals in an outdoor pool. Watch the impish seals entertain with amusing impressions of vacationers, such as bathers in an onsen — complete with a wooden bucket, a bottle of sake, and a towel on their heads. At the Seawater Pavillion, said to be Japan’s highest saltwater aquarium, marvel at a seven-meter-tall tank housing a sunken vessel and schools of colorful saltwater fish within. Look out for rare fish from the Amazon River, and appearances by divers who enter the tank for the daily feeding. You’ll also get to see other fascinating creatures such as Japanese spider crabs, sharks, jellyfish in an atmospheric illuminated tank, penguins, a beluga whale, and the African lungfish — a prehistoric fish sometimes referred to as “living fossils.” Book now to discover the wonders of life beneath the sea at Hakone!
