The Kaikyō Line (海峡線, Kaikyō-sen) is an 87.8 km (54.6 mi) railway line operated by Hokkaido Railway Company (JR Hokkaido). The line connects Naka-Oguni Station in Sotogahama, Aomori, through the Seikan Tunnel connecting Honshu and Hokkaido, to Kikonai Station in Kikonai, Hokkaido.
The line was opened on 13 March 1988 in conjunction with the opening of the Seikan Tunnel. In addition to passenger trains, freight services operated by Japan Freight Railway Company (JR Freight) operated on the line.
The Hokkaido Shinkansen commenced operation on 26 May 2016 replacing all conventional line passenger services, with the Kaikyō Line now only used by freight trains (and from May 2017 the luxury cruise train Train Suite Shikishima).
