Guided river access is the normal setup because flow and local rules are part of the dive.
Nagaragawa River is a clear freshwater dive site in Gifu where the river itself is the main terrain. The shallow-to-moderate water, drift-style current, and guided river-bank entry create a very different kind of dive around ayu, catfish, trout, eels, crabs, and giant-salamander habitat. It is a controlled freshwater outing, not a static lake dive.
Safety Notes
River flow, water level, and localized current changes can affect entry, exit, and drift behavior. Stay with the guide and respect local rules.
