Aquamarine Fukushima (アクアマリンふくしま) is an aquarium located in the city of Iwaki, along the coast facing the Pacific Ocean. It has an extensive collection of various fish species, and does a wonderful job in demonstrating ecosystems in the waters of Fukushima Prefecture and different parts of the world. The aquarium was damaged by the March 2011 tsunami but was reopened in July 2011.
In one section, the natural aquatic environment of Fukushima Prefecture is recreated, from the rivers and lakes in the mountainous interior to the shores along the Pacific Coast, exhibiting the diverse animal and plant life. A large triangular tank demonstrates the current rip where the Kuroshio Current from the south and the Oyashio Current from the north meet off the coast of Fukushima.
Among the various other displays at Aquamarine Fukushima, the "Waters of Tropical Asia" attraction recreates the waterside nature of tropical Asia in a greenhouse, and the "Okhotsk Sea" tank puts on display the assortment of creatures that live in the Sea of Okhotsk, north of Hokkaido.
The aquarium further keeps a fascinating selection of rarely seen fishes and sea creatures, as well as a large collection of different types of goldfish. In addition, there is a pool where visitors can try touching starfishes, and a marine mammals section where visitors can view seals and walruses.
A further 25 minute walk takes you to the 60 meter tall Iwaki Marine Tower, a landmark within Misaki Park. Visitors are able to ascend the tower for a good view of the Pacific Ocean. Misaki Park is a big area with lots of open space designed for families to have a good time together outdoors. There are playgrounds for children, including a maze and a long slide. There is also an interesting platform protruding out above the sea, providing a scenic vantage point.
