Kurobe Gorge Railway – Toyama

Overview

The Kurobe Gorge Railway is a narrow-gauge sightseeing railway running deep into Kurobe Gorge in Toyama Prefecture, northern Japan. Famous for its open-air trolley cars, steep mountain scenery, emerald-green rivers, and dramatic seasonal landscapes, it is widely regarded as Japan’s most spectacular mountain railway.

Originally built for hydroelectric power development, the railway is now one of Japan’s premier scenic attractions, offering visitors access to otherwise unreachable alpine wilderness.

Geographical Setting

Kurobe Gorge lies within the Northern Japan Alps, carved by the fast-flowing Kurobe River over millions of years. The gorge is characterized by:

The railway follows the river upstream, revealing landscapes that change dramatically with altitude.

History of the Railway

The Kurobe Gorge Railway was originally constructed in the early 20th century to support:

• Hydroelectric dam construction

• Transport of materials and workers into remote mountain areas

Over time, parts of the line were opened to the public, transforming a purely industrial railway into a scenic tourist route. Despite this transition, the railway still maintains its rugged, utilitarian character.
