Kishū Railway Line

The line was conceived to connect the Kisei Main Line's Gobō Station, which sits on the edge of town, with the centre of Gobō. Local promoters led by Eijirō Tabuchi, a major Gobō landowner, applied to the Railway Minister for a construction licence in November 1927. The licence was granted in March 1928, and the Gobō Rinkō Railway (御坊臨港鉄道, "Gobō Portside Railway") was incorporated on 13 December 1928, with Tabuchi as its first president.

Construction was meant to coincide with the opening of the national Kisei West Line (now the Kisei Main Line) to Gobō in 1929, but land-acquisition disputes — including a year-long compensation wrangle with tenant farmers in Yukawa village — delayed the work. The first section, from Gobō to Gobō-machi (now Kii-Gobō), a distance of 1.74 km, finally opened on 15 June 1931. Further extension was slowed by the financial slump and land-expropriation procedures: the line reached Matsubaraguchi (now Nishi-Gobō) on 10 April 1932, and was completed through to Hidakagawa on 10 August 1934, when freight service also began.

Business was weak from the outset and the company posted losses almost every year. To boost revenue it built a freight siding and courted day-trippers along a designated hiking course, and from 1937 it received a government subsidy, yet by late 1941 accumulated losses were substantial. During the Second World War, the conversion of nearby Daiwabō textile mills into an aircraft-parts factory caused passenger numbers to surge, but fuel rationing forced the railcars onto underpowered charcoal-gas generators, and an air raid in June 1945 destroyed two railcars when the engine shed took a direct hit.

Recovery came with secondhand stock bought or borrowed from the national railways and the Yawata steelworks. In July 1953 the Kishū great flood caused the Hidaka River to overflow, submerging the entire line and forcing a two-month suspension before the Gobō–Nishi-Gobō section reopened on 15 September. Ridership nonetheless recovered, reaching about a million passengers a year by the mid-1960s before entering a long decline. On 1 January 1973 the railway business was sold to a Tokyo property company and renamed the Kishū Railway; the new owner, which was not previously a railway operator, took the line over largely for the prestige and public trust that came with running a railway.

From 1955 to 1984 a 0.85 km private siding ran west of Nishi-Gobō to a Daiwabō textile mill, carrying freight. Stations were added and removed over the decades: three halts were closed in December 1941, Shiyakusho-mae opened in 1967, and Gakumon opened in 1979. As Japan's national railways rationalised freight, the line ended freight operations on 1 February 1984 and closed the Daiwabō siding that June.

On 1 April 1989 the lightly used 0.7 km section from Nishi-Gobō to Hidakagawa was closed, leaving the line at its present length of 2.7 km, and one-man operation began the same day. A derailment on 22 January 2017 between Gobō and Gakumon, attributed to ageing wooden sleepers, suspended services for a month until trains resumed on 23 February; the line then undertook a long-running programme to replace its sleepers with prestressed concrete. In September 2023 the line and the abandoned Gobō Rinkō Railway formation were recognised as a Selected Civil Engineering Heritage by the Japan Society of Civil Engineers.

After the Kishū Railway itself was bought by a Chinese property and resort developer in December 2022, the parent company moved in 2024 to abolish the line, and through 2025 and 2026 the railway sought a successor operator amid the threat of closure. The line carries roughly fifteen round trips a day, timed mainly to connect with JR Kisei Main Line local trains at Gobō, and its future remains uncertain.
