What to know
The Kurobe Gorge (黒部峡谷, Kurobe Kyōkoku) is a stunning forested ravine in the rugged Northern Japan Alps. Carved by the Kurobe River, it ranks among Japan's deepest gorges. Its steep cliffs, pristine forests, and outdoor hot springs make it a celebrated destination for natural beauty. Note: it is distinct from the nearby Tateyama-Kurobe Alpine Route, which is accessed from a different direction.
The highlight is the Kurobe Gorge Railway, a sightseeing train originally built for constructing the Kurobe Dam. Today, small trains run along a winding 20-kilometer stretch between Unazuki and Keyakidaira stations. The thrilling 80-minute ride crosses over 20 bridges and passes through over 40 tunnels, offering panoramic views of the gorge below. Passengers can alight at several stations to explore.
Trains operate seasonally from late April to November, peaking in autumn when the forested slopes blaze with bright orange and red fall colors. Thanks to the wide elevation range, the gorge enjoys a long foliage season, typically from mid-October to mid-November.
Most trains have two types of cars: open-sided cars with 4-person bench seats (no backrests) and enclosed cars with more comfortable seating for an extra fee. When you buy a ticket, you get a car number, but seats within the car are unnumbered. For the best views, sit on the right side heading into the gorge.
Unazuki Station, the departure point, is in Unazuki Onsen, a small hot spring town at the gorge entrance. The town offers several hot spring baths, hotels, ryokan, museums, and walking trails leading into the gorge.
