Seto-Ōhashi Line

The Seto-Ōhashi Line (瀬戸大橋線, Seto-Ōhashi-sen) is a railway line operated by West Japan Railway Company (JR West) and Shikoku Railway Company (JR Shikoku) in Japan which links Okayama Station in Okayama Prefecture with Takamatsu Station in Kagawa Prefecture via the Great Seto Bridge. It is not a distinct railway line, but an official nickname given to a composite section formed of three different lines. Service commenced along with the opening of the Great Seto Bridge in 1988.
