Kujukushima Aquarium Sea Kirara is a unique facility themed around the beautiful waters surrounding the Kujukushima islands in Sasebo, Nagasaki Prefecture. The aquarium expresses the rich natural environment of the region, showcasing approximately 1,000 species of organisms found in the local waters and the unique topography of the area. With the concept of the 'sparkle of the sea,' the exhibits use beautiful lighting and displays to convey the power of life and the mysteries of the ocean.
The Kujukushima area, with its complex terrain and abundant natural resources, has been a cradle for diverse marine life for centuries. The local culture is deeply rooted in living alongside the sea, which has historically provided sustenance and life to the community. Sea Kirara serves as a bridge to the next generation, preserving the local connection to the sea and educating visitors about the importance of natural habitats, such as seagrass beds (amamo), and the eternal cycle of nature.

The interior features exhibits that faithfully reproduce the natural environment of Kujukushima. For instance, the large tanks designed to mimic the waters of the outer sea of Kujukushima and the Goto Islands highlight the unique water movements and marine life specific to this region. Visitors can also observe rare creatures, such as horseshoe crabs, in environments that closely resemble their natural habitats. The jellyfish exhibition area is particularly enchanting, offering a dreamlike space where light and water movement create a mesmerizing atmosphere.
While the aquarium is enjoyable year-round, we recommend visiting during daylight hours to fully appreciate the light effects. Certain areas utilize light-based displays that change the way marine life appears depending on the time of day. Please note that operating hours vary by season: from March to October, the facility is open until 18:00, and from November to February, it closes at 17:00. Enjoying the tranquil atmosphere of the illuminated tanks in the late afternoon is a luxurious way to experience the aquarium.
Beyond simple observation, the aquarium offers rich educational content, including exhibits themed around the seas of the Goto Islands and sections where you can learn about the ecology of various species. Programs such as the pearl extraction experience allow visitors to engage with the local culture and natural wonders. The layout is designed to help visitors visually understand how marine life survives and coexists with the natural environment.
The area around Sasebo City, where the aquarium is located, is filled with spots perfect for nature observation and island cruising. After exploring the marine life at the aquarium, we recommend combining your visit with a cruise around the islands or a walk along the scenic coastlines. This makes for a highly satisfying travel itinerary centered around the beautiful themes of the sea and the Kujukushima islands.
