The is a railway line in Japan operated by the East Japan Railway Company (JR East). The line runs from Ueno Station in Ueno, Tokyo through major cities including Saitama, Utsunomiya, Fukushima, and Sendai, terminating at Morioka in Iwate Prefecture. The line originally extended to Aomori, but was truncated following the extension of the TÃ Âhoku Shinkansen beyond Morioka, which largely parallels the former route.
A portion of the Tà Âhoku Main Line is shared with the KeihinâÂÂTà Âhoku Line (between Ueno and à Âmiya Station in à Âmiya-ku, Saitama) and the Saikyà  Line (between Akabane Station in the Kita ward of Tokyo and à Âmiya Station).
In regular service, JR East applies different service names to sections of the TÃ Âhoku Main Line. The section between Tokyo Station and Kuroiso Station in Nasushiobara, Tochigi Prefecture is referred to as the Utsunomiya Line, while the remaining northern portion is referred to as the TÃ Âhoku Line. This distinction reflects a change in electrification from south of Kuroiso to north of the station; as a result, there are no regularly scheduled passenger services operating through Kuroiso Station.
These lists are separated by service patterns provided on the TÃ Âhoku Main Line.
The section between and is known as the Utsunomiya Line.
All stations are located in Fukushima Prefecture.
Legends:
All stations are located in Iwate Prefecture.

From March 2013, a fleet of eight refurbished 4-car 205-600 series EMUs was phased in on Utsunomiya Line services between Koganei and Kuroiso, replacing 211 series sets.
The construction of the Tà Âhoku Main Line began in the Kantà  region and extended to the north end of Honshu, and the city of Aomori. It is one of oldest railway lines in Japan, with construction beginning in the late 19th century. Until 1 November 1906, the current Tà Âhoku Main Line was run by a private company Nippon Railway.
In 1883, the first segment between Ueno and Kumagaya opened. In 1885, it was extended to Utsunomiya, but the Tone River had to be crossed by boat. Following construction of the Tone River Bridge in 1886, Utsunomiya and Ueno were directly connected. The line gradually extended further to the north; to KÃ Âriyama, Sendai, Ichinoseki and Morioka. In 1891, the segment between Morioka and Aomori opened, creating the longest continuous railway line in Japan.
After 1906, the line was nationalized and became the Tà Âhoku Main Line operated by the Ministry of Railways. When Tokyo Station opened in 1925, the Tà Âhoku Main Line was extended from Ueno to the new station. Until the 1950s, this segment was used and many trains ran through both the Tà Âkaidà  Main Line and Tà Âhoku Main Line. However, when the Tà Âhoku Shinkansen opened, it occupied land previously used for the tracks of mid and long-distance Tà Âhoku Main Line trains. As a result, only a small number of commuter lines (such as the KeihinâÂÂTà Âhoku Line) operated from Ueno to Tokyo, making Tokyo Station's status as part of the Tà Âhoku Main Line somewhat circumspect, until the UenoâÂÂTokyo Line opened in 2015, connecting the two stations (with the exception of the occasional train that terminates at Ueno Station).
In 2002, the TÃ Âhoku Shinkansen was extended from Morioka to Hachinohe and the operations of the local track segment between those two cities was turned over to Iwate Ginga Railway (IGR) and Aoimori Railway. With the extension of the TÃ Âhoku Shinkansen to Shin-Aomori station in 2010, the segment between Hachinohe and Aomori was delegated to the Aoimori Railway Company. The shortened TÃ Âhoku Main Line is now the second-longest line in Japan, after the Sanin Main Line.
The Tokyo to Omiya section was double-tracked between 1892 and 1896, extended to Koga in 1908, Oyama the following year, and to Utsunomiya in 1913.
The Iwanuma - Sendai - Iwakiri section was double-tracked between 1920 & 1923 and the Utsunomiya - Iwanuma section between 1959 and 1964. The Iwakiri - Morioka - Aomori section was double-tracked between 1951 and 1968, including the realigned section between Iwakiri and Atago in 1962.
The Tokyo to Tabata section was electrified at 1,500 V DC in 1909, extended to Akabane in 1928, Omiya in 1932 and Kuroiso in 1959. Electrification was then continued north at 20 kV AC, reaching Fukushima in 1960, Sendai in 1961, Morioka in 1965, and Aomori in 1968.
