The aquarium features specialized exhibition areas that recreate the rich biodiversity of the Pacific Ocean. You can observe charming marine creatures such as otters, seals, and garden eels, often accompanied by engaging video displays. The exhibits are designed to be visually captivating, and during certain seasons, you can enjoy traditional Japanese decorations like 'tsurushi-kazari' (hanging ornaments), adding a touch of local culture to your visit.
There are different ways to enjoy Aquamarine Fukushima depending on when you visit. For example, in the spring, you might see special decorations related to the Hina Matsuri festival.
