Tsugaru Railway Line

The railway grew directly out of the nationalisation of a neighbouring line. The Mutsu Railway had run the Kawabe–Goshogawara line (today part of the JR Gonō Line), and when the state bought it out its shareholders received twice the sum they had originally invested. Looking for the next railway venture in the Tsugaru region, they planned a line from Goshogawara north to Nakasato and established the Tsugaru Railway to build and operate it. The promoters held a founding conference on 28 June 1927 and a founders' meeting on 4 July 1927; a railway construction licence for the Goshogawara–Nakasato route was granted on 13 February 1928, and the company was incorporated on 24 February 1928 with capital of one million yen.

Construction began on 10 November 1928, and the line opened in three stages during 1930. The first section, from Goshogawara Station (today's Tsugaru-Goshogawara) to Kanagi, a distance of 12.8 km, opened on 15 July 1930; the inaugural service was train No. 101, which left Goshogawara at 6:18 in the morning for Kanagi, and the opening timetable offered seven round trips a day — three in the morning and four in the afternoon. The line was extended from Kanagi to Ōzawanai (4.9 km) on 4 October 1930, and the final section from Ōzawanai to Tsugaru-Nakasato (3.0 km) opened on 13 November 1930, completing the through line of 20.7 km; freight service between Kanagi and Nakasato began the same day. A ceremony marking the opening of the full line was held on 5 July 1931.

The young company struggled financially in the aftermath of the Shōwa financial crisis. To raise revenue it diversified into the bus business, beginning in 1934 with the purchase of the Kanagi–Nakasato route of the Kanagi Motorcar partnership and steadily buying up neighbouring bus operators; by the wartime years bus fares accounted for a large share of its income. The bus operation was eventually handed over to Kōnan Bus in March 1955. On the railway itself, petrol-engine traction was introduced alongside steam on 24 April 1932 and heavy-oil traction on 14 April 1933, and on 10 July 1956 the starting station, Goshogawara, was renamed Tsugaru-Goshogawara to distinguish it from the adjacent government station of the same name.

In the post-war decades the line settled into the role of a rural feeder serving Goshogawara, the town of Kanagi and the communities of the central Tsugaru Peninsula. Passenger traffic peaked in the mid-1970s and declined steadily thereafter as the local population fell and car ownership spread. Freight, which had been carried since the 1930 opening, was discontinued entirely on 1 February 1984. To contain costs the railway introduced one-man operation on some trains on 1 April 1992, and in November 2004 a winter timetable revision sharply cut the number of services and simplified signalling, operating the Tsugaru-Goshogawara–Kanagi section as a single block and converting the Kanagi–Tsugaru-Nakasato section to staff-token working.

It is the line's seasonal trains, rather than its commuter role, that have given it a national profile. In winter, from 1 December to 31 March, a 'Stove Train' is run, formed of traditional passenger carriages heated by a coal-burning potbelly (daruma) stove; a supplementary 'Stove Train' fare is required to ride the heated cars. The fee was first introduced on 1 December 2007 at 300 yen to help meet the rising cost of running the train, and was raised to 400 yen on 1 December 2014 and to 500 yen on 1 December 2020. In summer, from 1 July to 31 August, locally made wind chimes and haiku strips are hung in the carriages to run them as 'Fūrin' (wind-chime) trains, and from 1 September to mid-October cages of singing 'Suzumushi' bell crickets are placed aboard to make the 'Suzumushi' trains. The line's everyday railcars, named 'Run, Melos!' after a work by the writer Osamu Dazai, who was born in Kanagi along the line, underscore its strong literary and tourist associations.

The Tsugaru Railway Line remains a rare survivor of its kind. After the closure of the Shimokita Kōtsū Ōhata Line in April 2001 it became the only non-electrified private railway left in Aomori Prefecture, and — leaving aside lines converted from the former Japanese National Railways and JR — the only such line in the entire Tōhoku region. As of 2019 it was also the only operating railway in Japan still using semaphore (mechanical arm) signals in regular service, at Tsugaru-Goshogawara and Kanagi, though only as home signals. Faced with a shortage of qualified drivers, the company carried out a timetable revision on 1 June 2025 that cut two up and three down services while preserving the trains used by commuting students, underlining the financial pressures that the small, much-loved line continues to face.
