The Jōban Line is a railway line in Japan operated by the East Japan Railway Company. 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.

Ueno Station is a major railway station in Tokyo's Taitō ward. It is the station used to reach the Ueno district and Ueno Park—which contains Tokyo National Museum, The National Museum of Western Art, Ueno Zoo, Tokyo University of the Arts and other famous cultural facilities. A major commuter hub, it is also the traditional terminus for long-distance trains from northern Japan, although with the extension of the Shinkansen lines to Tokyo Station this role has diminished in recent years. A similar extension of conventional lines extended Takasaki Line, Utsunomiya Line and Jōban Line services to Tokyo Station via the Ueno-Tokyo Line in March 2015, using existing little-used tracks and a new viaduct; the Ueno-Tokyo Line connects these lines with the Tōkaidō Main Line, allowing through services to Shinagawa, Yokohama, Odawara and Atami stations.
