Right on the Shonan coast facing Enoshima island, the Enoshima Aquarium — affectionately known as “Enosui” — is one of the Tokyo area’s most beloved aquariums, blending marine science with a stunning seaside setting. Its star exhibits showcase Sagami Bay, the deep, biodiverse waters just offshore, in a giant tank teeming with sardines, plus a dreamy jellyfish hall, playful dolphin and sea-lion shows staged against a backdrop of the real ocean and Mt. Fuji. With penguins, sea otters and hands-on touch pools, it’s a perfect family stop that pairs beautifully with a day on the Shonan beaches.
This guide covers the highlights, shows, tickets, the best time and access.
