The Shinano River, Japan’s longest at roughly 367 km, rises in the mountains of Nagano prefecture (where it’s known as the Chikuma River) before flowing north through Niigata and emptying into the Sea of Japan at Niigata City. The river and its extensive floodplain have shaped the region for centuries, its fertile silt deposits creating some of Japan’s most productive rice-growing plains, and its lower reaches near Niigata City offer pleasant riverside walking paths, historic bridges and views that shift with the seasons.
