The aquarium uses a 'river-profile' layout that mimics the flow of the Sagami River from the mountains down to the sea.
It houses the Ayu (sweetfish), which is considered the representative fish of the Sagami River.
The facility acts as a research center for studying the endangered species found within the local river system.
The building features glass-walled observation areas that allow visitors to see the aquatic life from multiple depth levels.
Sagamihara Aquarium, formally known as the Sagamigawa Fureai Science Museum, focuses exclusively on the freshwater ecosystems of the Sagami River. The facility features a large central tank designed to replicate the river's longitudinal profile from headwaters to the estuary. Visitors can observe various native fish species, including the Japanese dace and large carp, within habitats mimicking their natural environment. Interactive elements include a touch tank where visitors can engage with aquatic life directly. The museum emphasizes environmental education, detailing the geological and biological history of the Sagami River basin. Rotating seasonal displays highlight specific life cycles and river-related phenomena. It serves as a research hub for regional freshwater biodiversity and conservation efforts.
The large panoramic glass tank that provides a view of the river's cross-section is the premier photo opportunity.
Check the event board at the entrance for daily feeding times, as these are the most interactive periods.
The outdoor park area surrounding the museum is excellent for picnics and walks along the riverbank.
Visit on a weekday to avoid crowds, as local school groups frequently visit on weekends.
Do not assume the aquarium features saltwater or tropical marine exhibits; this is strictly a local freshwater facility.
Closed on Mondays, unless the Monday is a public holiday, in which case it remains open and closes the following Tuesday.
Avoid flash photography near the tanks to protect the fish; maintain a quiet voice to keep the environment calm.
