The Jōban Line (Japanese: 常磐線, Japanese pronunciation: [Jōban-sen]) is a railway line in Japan operated by the East Japan Railway Company (JR East). The line officially begins at Nippori Station in Arakawa, Tokyo before the line officially ends at Iwanuma Station in Iwanuma, Miyagi. However, following the opening of the Ueno–Tokyo Line, Jōban Line train services originate at Shinagawa or Ueno; likewise, Jōban Line trains continue past Iwanuma onto the Tōhoku Main Line tracks to Sendai. The line approximately parallels the Pacific coasts of Chiba, Ibaraki, and Fukushima Prefectures.
