Etsumi-Nan Line

The line began as the southern half of a never-completed trunk route, the Etsumi Line, intended to link the Mino region of Gifu Prefecture with the Echizen region of Fukui Prefecture and reach the Sea of Japan coast by way of the Nagara River valley. Construction started from the Mino-Ōta end, and the first section, from Mino-Ōta to Mino-machi (today's Minoshi), opened on 5 October 1923. The Railway Ministry then extended the line steadily northward over the following years.

The railway was pushed up the valley in a series of short segments through the 1920s and early 1930s — reaching Itadoriguchi (today's Yunohora-Onsen-guchi) in 1926, Gujō-Hachiman in 1929, and Mino-Shirotori in 1933 — until the final stretch from Mino-Shirotori to Hokunō opened on 16 August 1934, completing the present Etsumi-Nan Line. Although a short length of track was laid beyond Hokunō, no further construction was carried out, and the planned junction with the Etsumi-Hoku Line ("Etsumi North Line"), the corresponding line built from the Fukui side, was never realized; the two lines remain unconnected to this day.

Under JNR the route filled in over the following decades. A number of intermediate stations were added in the 1950s — among them the stations later renamed Yasaka, Fukuno and Akaike, together with Kamono and Sekiguchi, in 1952, and Tokunaga, Mamba and Ōshima in 1955 — and the station later renamed Suhara opened in 1957. Mileposts were converted from miles to kilometres in 1930. From 1966 the line carried a Nagoya-bound express, the "Okumino," coupled to a Takayama Main Line express between Nagoya and Mino-Ōta; it was downgraded to a local train within the Etsumi-Nan Line in 1969 and lost its Nagoya through service in 1982. Freight operations over the whole line ended on 1 October 1974.

With the impending breakup and privatisation of JNR, the Etsumi-Nan Line was designated a Specified Local Line — a route slated for closure or conversion because of low traffic — and its abolition was approved on 22 June 1984 as part of the second batch of such lines. Rather than close it, local authorities decided to keep the line running under a new third-sector company. The Nagaragawa Railway was incorporated on 28 August 1986, and on 11 December 1986 the JNR Etsumi-Nan Line (72.2 km) was abolished and reopened the same day as the Nagaragawa Railway Etsumi-Nan Line (72.1 km), the slight reduction coming from a re-measurement of the Futsukamachi–Hokunō section.

The transfer brought a wave of renamings and new stations. Six stations, including Maehira-Kōen, Seki-Tomioka and Shizenen-mae, opened on the day of conversion, and many existing stations were given their present names. Infill stations continued to be added under Nagaragawa Railway — Umeyama and Kami-Mamba in 1987, Hakusan-Nagataki in 1988, Seki-Shiyakusho-mae and Matsumori in 1999, and Minami-Kodakara-Onsen in 2002 — so that the station count rose from 26 at the time of transfer to 38. After the parallel Meitetsu Mino-machi Line lost its Shin-Seki–Mino section in 1999, the Etsumi-Nan Line added stations on the Seki–Minoshi stretch to take over some of that line's local role.

The scenic line along the Nagara River has become popular with tourists. An open-sided trolley train ran from 1992 until 2003, when it was withdrawn after the locomotive hauling it derailed. From 27 April 2016 the railway has run the "Nagara" sightseeing train, with interiors designed by Eiji Mitooka, offering meals made from local ingredients on services between Mino-Ōta and Hokunō. Today the line carries more than twenty-four round trips a day when short-turn services are counted — more than in the JNR era — and remains the lifeline rail link through the upper Nagara valley.
