The Tsugaru-Kaikyō Line (津軽海峡線, Tsugaru-Kaikyō-sen) was a railway line in northern Japan that linked Aomori Station in Aomori Prefecture and Hakodate Station in Hokkaido.
The name was created following the opening of the Kaikyō Line and Seikan Tunnel on 13 March 1988.
The section of line between Naka-Oguni and Kikonai Station ceased operation for conventional line passenger trains like Hakuchō and Super Hakuchō and sleeper trains like Hokutosei, Cassiopeia, Twilight Express and Hamanasu by the 21 March 2015.
[1] Today this section is only operated by the Hokkaido Shinkansen, conventional line freight trains and the tourist train Shikishima.
