Shinjiko Nature Museum Gobius is an interactive nature museum and aquarium located on the shores of Lake Shinji in Izumo City, Shimane Prefecture. The museum introduces the diverse aquatic life found in freshwater and brackish-water environments, with a particular focus on the unique ecosystems of Shimane.
With the theme “Discover the Nature of Our Home and Get Close to the Life of the Water,” Gobius offers visitors an opportunity to learn about the local environment while enjoying close encounters with its fascinating creatures.
One of Gobius’s greatest attractions is its focus on creatures that live in brackish water. Brackish water is created when freshwater and seawater mix, producing an environment with a salinity level between that of rivers and the ocean.
Lake Shinji and nearby Lake Nakaumi are well-known brackish lakes in Japan. Their changing salinity creates a distinctive environment where aquatic creatures have adapted to a wide range of conditions.
Inside the museum, visitors can see carefully recreated environments representing Lake Shinji, Lake Nakaumi, and rivers throughout Shimane. The exhibits make it possible to understand these ecosystems while feeling as though you are exploring the natural environment itself.
Gobius features a wide variety of aquariums and exhibits displaying approximately 200 species and 10,000 individual creatures.
The collection includes not only fish but also amphibians, crustaceans, insects, and other aquatic life. Together, the exhibits provide a broad introduction to the interconnected ecosystems found around Shimane’s rivers, lakes, and coastal waters.
Among the most impressive displays are a large diorama aquarium recreating the landscape of Lake Shinji and a river exhibit stretching approximately 20 meters.
The river exhibit allows visitors to follow the changing environment from the upper reaches of a river to its lower reaches. It also demonstrates how the plants and animals living there change according to differences in water conditions and habitat.
One of the most popular exhibits at Gobius is the “Helmet Aquarium.” The aquarium is designed so that visitors can place their heads inside an opening and look directly into the underwater world.
Fish swim surprisingly close to the viewer, creating the feeling of actually being underwater. The immersive design makes this exhibit particularly enjoyable for children and adults alike.
Gobius is designed not simply as a place to look at animals but as a place where visitors can learn through direct experience.
At the “Dandan Touch Pool,” visitors can safely interact with creatures such as freshwater crabs and small fish. The touch pool is designed at three different heights so that young children, older children, and adults can all enjoy the experience comfortably.
On weekends and public holidays, aquarium staff also hold educational programs that explain the behavior and characteristics of the animals.
During the popular “Let’s Watch the Fish Eat!” program, visitors can observe feeding time while learning about the animals’ natural habits and lifestyles. The explanations provided by knowledgeable staff make the experience both entertaining and educational.
Another distinctive feature of Gobius is its year-round display of shira-uo, or whitebait.
Whitebait are small, delicate fish with translucent bodies. Because they are normally available for viewing only during certain seasons, seeing them throughout the year is unusual.
Gobius has successfully developed techniques for their artificial breeding and captive rearing, allowing visitors to observe these fascinating fish throughout the year.
This work is also connected with efforts to protect and preserve the region’s aquatic biodiversity, making the exhibit valuable not only as a visitor attraction but also as part of local conservation activities.
Gobius serves an important role beyond displaying aquatic creatures. It is also a center for environmental education, research, and conservation.
Museum staff regularly conduct field surveys to monitor the condition of local habitats and observe changes in populations of aquatic organisms. These activities help build a better understanding of the region’s rivers, lakes, and wetlands.
The museum also works to protect and breed rare and endangered species. Through these efforts, Gobius contributes to preserving Shimane’s natural resources and passing them on to future generations.
One of the first sights visitors encounter after entering the museum is a pond where turtles swim in a natural-looking environment.
If you visit at the right time of year, you may even have the opportunity to see turtles laying eggs or young turtles hatching, offering a memorable glimpse into their life cycle.
From the turtle pond, visitors can explore the exhibits in sequence, beginning with the brackish-water zone and continuing to the river zone.
This layout makes it easy to understand how aquatic environments differ and how animals have adapted to each habitat.
Along the way, video displays and quiz areas provide additional opportunities to learn. These interactive features are especially appealing to children, allowing them to discover the natural world through play and exploration.
The museum’s nickname, “Gobius,” comes from Latin and refers to small fish, particularly fish belonging to the goby family.
Goby species are commonly found in the waters of Shimane, including its rivers, lakes, and brackish environments. The name therefore reflects the museum’s close connection with the local aquatic ecosystem.
Shinjiko Nature Museum Gobius is easily accessible by public transportation. It is approximately a 10-minute walk from Koyukan-Shin Station on the Ichibata Railway.
For travelers arriving by car, the museum is approximately 10 minutes from Izumo Airport, making it a convenient stop before or after a flight.
The museum is also surrounded by the beautiful scenery of Lake Shinji. Visitors can combine their aquarium visit with a leisurely walk along the lakeshore and enjoy the changing landscape of the lake.
