The Kiso River flows down from the Kiso Valley of the Central Alps to sweep past Inuyama in a broad, green corridor that a Meiji-era geographer famously nicknamed the ‘Japanese Rhine’ — like the German river, it pairs castle-crowned bluffs with vine-green gorges and long gravel shoals. The Inuyama reach is the scenic heart: National Treasure Inuyama Castle rises directly above the water, sightseeing boats and seasonal cormorant-fishing cruises work the current, and riverside paths make for easy cycling and strolling, while upstream the river threads toward the old Nakasendo post towns of Tsumago and Magome on the Gifu-Nagano border.

Tips
The single best view is from the top floor of Inuyama Castle looking down the river’s sweep — or, reversed, from the Twin Bridge area at dusk when the keep is lit above the water. If the landscape hooks you, the upper Kiso Valley’s preserved post towns of Tsumago and Magome make a superb onward day by JR from Nagoya.
