The route is particularly famous for the high snow walls that line some of its roads in spring.
The route was carefully built so that the surrounding environment is not damaged.
Consequently, three lines go entirely under tunnels; among them, two are trolleybus lines.
The route goes through Tateyama in the Hida Mountains with a lot of scenic sites, including Kurobe dam.
Currently, the route is purely a sightseeing one, only used by tourists.
