JR Hokuriku Main Line Railway

The JR Hokuriku Main Line started operations between Tsuruga and Fukui in 1896, starting services running between Maibara and Fukui. The section between Tsuruga and Imajo is marked by mountainous terrain, and the initial rail tracks ran up a steep slope. After World War II, in order to increase logistical flows and boost transportation capacity, works were carried out to reduce the incline of the slope between Tsuruga and Imajo, as well as track doubling and electrification. For this purpose, the Hokuriku Tunnel, which was the longest tunnel in Japan at the time of its construction at 13.87km, was constructed, and remains till this day.
