Gonô-sen 五能線
MI Mutsu Iwasaki KK Kita Kanegasawa
S Shirakami Sanchi (Shirakami Mountain Range)
A Iwakisan volcano
This line runs along the partly very desolate north-west coast of Honshû, almost all the way closely following the Japan Sea (Nihon-kai) coastline. It starts at Higashi Noshiro, where the main West-coast line to northern Japan (the Ô'u Honsen) turns sharply away inland to Ôdate, Hirosaki and Aomori. By contrast, the Gonô-sen continues straight on, first to the town of Noshiro in northern Akita Prefecture. After Mutsu Iwasaki (50, 9 km from Higashi Noshiro) it crosses the border into Aomori Prefecture. To the east of the line rises the vast Shirakami Mountain Range, famous for its natural beauty and its beech forests, the highest peaks in the region reaching to 1250 m above sea level.
After leaving the fishing village Fukaura (66, 9 km from Higashi Noshiro) the train, first continuing northwards, rounds the tip of the peninsula shortly before reaching Kita Kanegasawa (90, 6 km from Higashi Noshiro), where the dominating Iwakisan volcano comes into view. On this section of the line tragedy struck in the early morning of December 2, 1972, when, after a bridge had been torn away, a train fell into the ravine and the locomotive (steam locomotive class 8620 no.28688) was swept out into the raging sea.
From Kita Kanegasawa the line runs eastward through more inhabited land to Ajigasawa (103, 8 km from Higashi Noshiro) and from here inland through farming settlements to Goshogawara (125, 7 km). Goshogawara is the starting point of the Tsugaru Tetsudô, which runs up northwards through the Tsugaru plain. At Goshogawara the Gonô-sen turns south through vast orchards – mainly apple orchards – to reach Kawabe on the Ô'u Honsen, 147, 2 km from Higashi Noshiro. All trains continue from here over the 6, 3 km stretch to the city of Hirosaki.
The timetable is quite complicated, with a few local trains over parts of the line but no indicated through-running services, although in one or two cases the same coaches will continue after a while up or down the line. The full journey using local trains takes about 4 1/2 hours. Moreover, according to the season, comfortable tourist trains cover the full Gonô-sen on specific days.
The first sections of the line were built in 1908 (from Higashi Noshiro to Noshiro) and 1918 (first as a private railway) from Kawabe in the north to Goshogawara. The full line was completed between 1924 and 1936. In 1983 it was interrupted for a time after the serious Japan Sea Earthquake of May 26. Freight services ended in 1983 (1984 on the section Kawabe – Goshogawara).
The name of the line Gonô-sen 五能線 derives from the towns of Goshogawara 五所川原 in the north and Noshiro 能代in the south。
