Tempoku Line

The Tempoku Line (天北線:Tempoku-sen) was a Japanese railway line operated by the Hokkaidō Railway Company (JR Hokkaidō).

The line connects Otoineppu Station in the Sōya Main Line, then passes through the Hamatombetsu Village at Hama-Tombetsu Station, and goes north to Wakkanai City at Minami-Wakkanai Station.

The line was discontinued in 1989 after JR Hokkaidō took control of the railway.

The line got its name to the two former provinces that it went through: Teshio (天塩) and Kitami (北見). The first character of Teshio (天) can also be read as "ten", and the first character of Kitami (北) can also be read as "hoku". By Japanese orthography, putting "ten" and "hoku" together makes "Tempoku".
