Aquamarine Fukushima

Aquamarine Fukushima is a 4,000-ton capacity aquarium located in Iwaki City, approximately 180 kilometers northeast of Tokyo. Opened in 2000, this marine science museum was designed to showcase the diverse aquatic life of the Shiome no Umi, the local coastal waters where the warm Kuroshio Current meets the cold Oyashio Current. The facility gained international attention as a symbol of resilience after successfully reopening in July 2011, just four months after suffering significant damage during the Great East Japan Earthquake and tsunami.

The aquarium's centerpiece is the 2,050-ton triangular main tank, one of Japan's largest, which recreates the Shiome no Umi ecosystem with over 25,000 fish representing 800 species. Visitors can observe this massive display from multiple levels, including an underwater tunnel that provides 360-degree views. The facility houses specialized exhibits featuring Fukushima's freshwater environments, including displays of local river fish, and maintains breeding programs for endangered species native to the region.

The aquarium operates dolphin and sea lion shows performed four to six times daily, depending on the season. The Eureka pavilion features interactive educational exhibits about marine conservation and ocean science. Children particularly enjoy the Beach Life exhibit, which recreates a tidal pool environment where they can safely touch starfish, sea urchins, and small rays under staff supervision.

Summer months (July through September) offer extended operating hours and special evening illumination events, while winter provides a more intimate experience with smaller crowds and clearer views of the main exhibits. The facility remains comfortable year-round with climate control, making it an ideal destination regardless of weather conditions.

Aquamarine Fukushima is accessible via JR Joban Line to Izumi Station, followed by a 15-minute bus ride on the Iwaki Kotsu bus to the aquarium stop. Alternatively, visitors can take the JR Joban Line to Yumoto Station and transfer to a 20-minute taxi ride. The facility is located within Iwaki Lalamew, a waterfront complex that includes restaurants and shops. Adult admission costs ¥1,850, with children's tickets priced at ¥900. The aquarium opens at 9:00 AM and closes between 5:00 PM and 5:30 PM depending on the season. Free parking is available for 800 vehicles.
