The Tōhoku Main Line (東北本線 Tōhoku-honsen) is a 575.7 km long railway line in Japan operated by the East Japan Railway Company (JR East). Although officially the line starts from Tokyo Station in Chiyoda, Tokyo, most of the long-distance trains actually begin at Ueno Station in Taitō, Tokyo, and pass through such cities as Saitama, Utsunomiya, Fukushima, and Sendai, before reaching the end of the line in Morioka. The line originally extended to Aomori, but was truncated upon the extension of the Tōhoku Shinkansen beyond Morioka, which mostly parallels the Tōhoku Main Line.
