The museum name 'Gobius' is derived from the scientific name of the goby, a fish family that characterizes the lake's brackish environment.
The water circulation system is engineered to mimic the salinity gradients found in the actual Lake Shinji-Nakaumi basin.
It is one of the few aquariums in Japan dedicated entirely to regional freshwater and brackish species rather than exotic marine life.
The facility is integrated into a larger prefectural park, allowing for seamless transition between the museum exhibits and the natural habitat of the lake shore.
It maintains a focus on the specific transition zone where freshwater species from the Hiikawa River meet saltwater influences from the Sea of Japan.
Shimane Prefectural Lake Shinji Nature Museum Gobius is a specialized aquarium located within Shimane Prefectural Shinjiko Nature Park that focuses exclusively on the freshwater and brackish aquatic life of the Lake Shinji and Nakaumi lagoon systems. The facility houses approximately 200 species and 20,000 individual organisms, emphasizing the unique ecosystem where river water meets the sea. Exhibits are arranged to replicate the natural flow from mountain headwaters through rivers and into the brackish lake basin. It functions as a research-oriented nature museum rather than a traditional entertainment aquarium, highlighting local biodiversity. The center features large panoramic tanks and hands-on touch pools designed to provide an intimate look at species like the Japanese eel and various goby fish. It serves as a hub for environmental education regarding the protection of the brackish water environment.

Combine your visit with a walk through the surrounding Shinjiko Nature Park trails.
Check the daily feeding schedule upon arrival to see local species active in their tanks.
Utilize the provided information placards which offer detailed biological data on endemic brackish water organisms.
Do not treat this as a high-octane aquarium; expect a quiet, educational facility focused on regional ecology rather than large marine mammals.
Closed on Tuesdays or the following day if Tuesday is a public holiday.
