History
The line was opened on 13 March 1988 in conjunction with the opening of the Seikan Tunnel. Originally the line ran both freight and passenger trains; the latter included daytime limited express ''
Hakuchō'' and night train ''
Hokutosei''.
Three of the stations on the Kaikyō Line, Tappi-Kaitei, Yoshioka-Kaitei, and Shiriuchi, were closed on 15 March 2014 due to construction work connected with the
Hokkaido Shinkansen, which opened on 26 March 2016.
From that time, this line has largely re-designed as a freight-only route, except for the ''
Train Suite Shikishima'' cruise train.
