Yamanote Line

Trains run from 04:26 to 01:04 the next day at intervals as short as 2 minutes during peak periods and four minutes at other times. A complete loop takes 59 to 65 minutes. All trains stop at each station. Trains are put into and taken out of service at (which for timetabling purposes is the line's start and terminus) and sometimes . Certain trains also start from Tamachi in the mornings and end at in the evenings. Trains which run clockwise are known as and those counter-clockwise as . (Trains travel on the left in Japan, as with road traffic.) The line also acts as a fare zone destination for JR tickets from locations outside Tokyo, permitting travel to any JR station on or within the loop. This refers to stations on the Yamanote Line as well as the Chūō-Sōbu and Chūō Rapid Lines and between and . The Yamanote Line colour used on all rolling stock, station signs and diagrams is JNR Yellow Green No.6 (■, Munsell code 7.5GY 6.5/7.8), known in Japanese as . == Ridership and overcrowding ==

Due to the Yamanote Line's central location connecting most of Tokyo's major commuter hubs and commercial areas, the line is very heavily used. Sections of the line were running over 250% capacity in the 1990s, and remained above 200% for most of the 2000s with most sections dropping below 150% in 2018. As of 2023, the congestion has dropped further to 125% on the outer loop and 131% on the inner loop. This is due to larger and more frequent trains being introduced to the Yamanote Line and the opening of parallel relief lines such as the Tokyo Metro and Ueno–Tokyo Line. The ridership intensity of the Yamanote Line in 2018 was 1,134,963 passengers - km / km of route. However, in both cases "Yamanote Line" refers to JR East's internal definition of the entire rail corridor between Shinagawa and Tabata stations via Shinjuku which includes the ridership of the Saikyō and Shōnan–Shinjuku Lines on the parallel Yamanote freight line. Meanwhile, the ridership of the Yamanote Line services between Tabata and Shinagawa Station via Tokyo are excluded and counted as part of the Tōhoku and Tōkaidō Main Lines. == Name ==

"Yamanote" literally refers to inland, hillier districts or foothills (as distinct from areas close to the sea). In Tokyo, "Yamanote" lies along the western side of the Yamanote Line loop. The word consists of the Japanese morphemes yama, meaning 'mountain', the genitive suffix no, and te, meaning 'hand', thus literally translating as "mountain's hand", analogous to the English term "foothills". Yamanote-sen is officially written in Japanese without the kana , which makes its pronunciation ambiguous in print. The characters may also be pronounced yamate, as in Yamate-dōri (Yamate Street), which runs parallel to the west side of the Yamanote Line. The Seishin-Yamate Line in Kobe and the Yamate area of Yokohama also use this pronunciation. After World War II, SCAP ordered all train placards to be romanized, and the Yamanote Line was romanized as "Yamate Line" due to a mistake made by one of the workers at JNR. It was thus alternatively known as "Yamanote" and "Yamate" until 1971, when the Japanese National Railways changed the pronunciation back to "Yamanote", as people started riding trains heading for Yamate thinking it goes to the Yamate Station located in Yokohama. Some older people still refer to the line as the "Yamate Line". == Station list ==

, the line's services are operated exclusively by a fleet of 50 11-car E235 series EMUs, the first of which was introduced on the line on 30 November 2015. However, a number of technical faults, including problems with door close indicators, resulted in the train being taken out of service the same day. The E235 series returned to service on the Yamanote Line on 7 March 2016. All Yamanote Line rolling stock are stored and maintained at near Ōsaki Station. to January 20, 2020. These trains originally each included two "six-door cars" with six pairs of doors per side and bench seats that were folded up to provide standing room only during the morning peak until 10 a.m. From February 22, 2010, the seats were no longer folded up during the morning peak, and all trains were standardized with newly built four-door cars by 31 August 2011. This was due to reduced congestion on the line as well as preparation for the installation of platform doors on all stations by 2017. The E231 series supported a new type of traffic control system, called digital Automatic Train Control (D-ATC). The series also had a more modern design and has two 15-inch LCD monitors above each door, one of which is used for displaying silent commercials, news and weather; and another which is used for displaying information on the next stop (in Japanese, English, Korean and more) along with notification of delays on Shinkansen and other railway lines in the greater Tokyo area. and on the tracks near Ebisu Station, 2023 • DeHo 6100 series (from 1909 until unknown date) • MoHa 10 • 63 series • 72 series • 101 series ("Canary" yellow livery, from September 1961 until circa 1968) • 205 series (from March 25, 1985 until April 17, 2005) • E231-500 series (from April 21, 2002 until January 20, 2020) File:JNR EC TYPE63 Prototype.jpg|63 series File:JRE-EC-101-Tsurumi-Line.jpg|A yellow (Tsurumi Line) 101 series train File:JNR EC Tc103-347.jpg|A Yamanote Line 103 series train in March 1985 File:Yamanote Line 205 series set 30 Tabata Station 20030202.JPG|A Yamanote Line 205 series train in February 2003 File:Series-E231-500 550 Yamanote-Line.jpg|A Yamanote Line E231-500 series set in August 2018 Timeline ==History==

The predecessor of the present-day Yamanote Line was opened on 1 March 1885 by the Nippon Railway Company, operating between Shinagawa Station in the south and Akabane Station in the north. The top part of the loop between and (a distance of ) opened on 1 April 1903, and both lines were merged to become the Yamanote Line on 12 October 1909. A parallel freight line, also completed in 1925, ran along the inner side of the loop between Shinagawa and Tabata. During the prewar era, the Ministry of Railways did not issue permits to private suburban railway companies for new lines to cross the Yamanote Line from their terminal stations to the central districts of Tokyo, forcing the companies to terminate services at stations on the line. This policy led to the development of around major transfer points on the Yamanote Line, most notably at and (which are now the two busiest passenger railway stations in the world). The contemporary Yamanote Line came into being on 19 November 1956 when it was separated from the Keihin-Tōhoku Line and given its own set of tracks along the eastern side of the loop between Shinagawa and . A new station, Takanawa Gateway Station, opened on 14 March 2020. This station was built on the Yamanote Line and Keihin-Tohoku Line between Shinagawa and Tamachi stations, becoming the first new station on the line since Nishi-Nippori was built in 1971. The distance between Shinagawa and Tamachi stations was , making it the longest stretch of track between stations on the Yamanote Line. In August 2025, JR East announced that it obtained government approval to raise fare by an average 7.1% from March 2026, which was the first blanket fare hike since 1987. On 16 September 2025, JR East announced that it would be operating a pair of E235 series trainsets with a special design commemorating 100 years since the opening of the existing Yamanote Line loop route. The design will pay tribute to former 103 series and 205 series that formerly operated on the line. ==See also==
