Marine World Uminonakamichi

Marine World Uminonakamichi is an aquarium located within National Uminonakamichi Seaside Park in Higashi Ward, Fukuoka City, Fukuoka Prefecture. Its official name is the “Marine Ecological Science Museum.” Opened in 1989, the aquarium features approximately 350 species and 30,000 aquatic animals under the theme of “The Seas of Kyushu.” It introduces the distinctive marine environments found throughout Kyushu, which is surrounded by the East China Sea, Pacific Ocean, Sea of Japan, and Seto Inland Sea, as well as the creatures that inhabit them. As visitors learn about the diversity of marine environments and ecosystems, they can also enjoy one of Kyushu’s leading aquariums.

In April 2017, the entire aquarium underwent renovation, and many of its tanks and exhibits were renewed. The facility was transformed into a place where natural habitats are represented more realistically, allowing visitors to experience the richness of “The Seas of Kyushu” at close range. In July 2022, “Kyushu Forest of Water” opened, introducing creatures that inhabit Kyushu’s rivers, ponds, watersides, rural areas, and satoyama landscapes. Visitors can learn not only about the sea but also about Kyushu’s abundant freshwater environments and waterside ecosystems.

The aquarium’s largest attraction is the “Pelagic Ocean Tank,” which is approximately 7 meters deep and holds about 1,400 tons of water. Extending across two stories, this impressive tank is home to a wide variety of fish, including sand tiger sharks, other sharks, rays, and huge schools of sardines. It recreates the warm waters of southern Kyushu, where the Kuroshio Current flows. The sight of large fish and schools of small fish moving through the same tank is truly spectacular.

The Pelagic Ocean Tank hosts programs such as “Diver Fish Watching” and shows featuring schools of sardines, depending on the schedule. During “Diver Fish Watching,” a diver uses an underwater camera to explain the characteristics and behavior of the creatures in an easy-to-understand way. Since the content and times of the shows may vary from day to day, visitors are advised to check the schedule on the official website before visiting.

The aquarium also offers a wide range of popular shows. At the open-air show pool overlooking Hakata Bay, dolphins and sea lions perform dynamic routines. From the dolphins’ graceful jumps and speedy swimming to the sea lions’ charming movements and perfectly synchronized performances with their trainers, the shows are enjoyable for visitors of all ages. Set against the blue sky and sea, these performances are one of Marine World Uminonakamichi’s signature attractions.

The outdoor area features numerous exhibits that allow visitors to feel closer to the animals. At “Penguin Beach,” visitors can observe Cape penguins up close as they live in an environment resembling their natural habitat, complete with sandy beaches and rocky areas. The penguins’ adorable behavior as they walk, swim, and spend time at their leisure is beloved by many visitors.

At “Island Stage,” visitors can enjoy seal performances from various angles around the stage. They can observe not only the seals swimming underwater but also their calls, facial expressions, and humorous movements up close, creating a strong sense of intimacy with the animals.

Another unique attraction at Marine World Uminonakamichi is the opportunity to observe finless porpoises, small cetaceans that also inhabit the coastal waters of northern Kyushu. They are characterized by their rounded bodies and gentle expressions, and visitors can enjoy watching them glide peacefully through the water. On certain days, paid feeding experiences with dolphins, seals, and sea lions may also be available, allowing visitors to feel even closer to the animals.

The aquarium displays a wide variety of marine life, including jellyfish and sea turtles. In the enchanting jellyfish exhibit, visitors can watch the creatures drift slowly through the water as they are illuminated by light, providing a peaceful and relaxing experience. There are also many exhibits where visitors can observe the unique characteristics and lifestyles of sea turtles, vividly colored fish, and other creatures.

“Kyushu Forest of Water” recreates environments ranging from the upper reaches to the lower reaches of Kyushu’s rivers, as well as ponds, watersides, rural areas, and satoyama landscapes. In addition to freshwater fish, the exhibit features aquatic insects, amphibians, reptiles, and more. Visitors can learn about the water cycle that connects these environments to the sea and the richness of Kyushu’s natural surroundings. The opportunity to discover the appeal of freshwater creatures, which differ from marine life, is another distinctive feature of this aquarium.

On designated days, mainly during the summer, the “Night Aquarium” event is held. On event days, the aquarium remains open until 9:00 p.m., and from 6:00 p.m., the lighting throughout the facility and its tanks is switched to nighttime illumination. In the darkened tanks, visitors can observe animal behavior that differs from what they see during the day, while the entire aquarium is enveloped in a magical atmosphere.

At night, special programs may also be offered, including sardine shows featuring sound and light. With different presentations and the quiet atmosphere of the illuminated tanks, visitors can enjoy an experience unlike that of regular operating hours. Since the event dates and show content vary depending on the year and schedule, it is recommended that visitors check the official website in advance.

The restaurant on the first floor offers the opportunity to dine while watching dolphins swim in the show pool. It serves aquarium-themed dishes and desserts, as well as menus for children, providing a relaxing place to take a break during a visit. Being able to watch dolphins swimming past the windows while enjoying a meal is one of the restaurant’s unique attractions.

The aquarium shop offers a wide selection of goods, including original Marine World Uminonakamichi merchandise, stuffed animals, stationery, sweets, and miscellaneous items featuring marine creatures. It is also a fun place to look for merchandise of favorite animals or souvenirs to remember a trip to Fukuoka.

Marine World Uminonakamichi places emphasis not only on exhibits and shows but also on educational and research activities. Through exhibit explanations and hands-on learning programs, it provides opportunities to study animal behavior, ecosystems, and the marine environment. The aquarium also conducts surveys and research on creatures including sand tiger sharks and finless porpoises, working to deepen understanding of marine life and the natural environment.

Set in a nature-rich location overlooking Hakata Bay, Marine World Uminonakamichi offers visitors an extensive experience of the appeal of Kyushu’s seas. From the spectacular Pelagic Ocean Tank and dolphin and sea lion shows to exhibits featuring finless porpoises and penguins, nighttime events, and hands-on programs, the aquarium offers something for everyone. It is one of Fukuoka’s most popular tourist attractions, welcoming families, couples, and groups of friends while providing visitors of all ages with opportunities for both learning and inspiration.
