Kurobe Gorge

Kurobe Gorge is the deepest V-shaped gorge in Japan, carved by the Kurobe River through the rugged Northern Alps of Toyama Prefecture. The main attraction is the Kurobe Gorge Railway, a scenic trolley train that runs along a 20-kilometer route from Unazuki Station deep into the mountains, crossing numerous bridges and passing through tunnels while offering spectacular views of the emerald-green river below. Several hot spring stops along the route allow visitors to soak in riverside open-air baths surrounded by pristine nature. The gorge is particularly stunning during autumn when the steep valley walls are painted in vivid shades of red, orange, and gold. The railway operates from late April to late November, with autumn colors typically peaking in late October to early November.
