The Yamanote Line (山手線 Yamanote-sen?) is a railway loop line in Tokyo, Japan, operated by East Japan Railway Company (JR East). It is one of Tokyo's busiest and most important lines, connecting most of Tokyo's major stations and urban centres, including the Yūrakuchō/Ginza area, Shibuya, Shinjuku, and Ikebukuro, with all but two of its 29 stations connecting to other railway or underground (subway) lines.

The "Yamanote Line" as an official line name indicates the tracks between Shinagawa and Tabata that is used by local trains on their own tracks as well as the parallel Yamanote Freight Line which is used by Saikyō Line and Shōnan-Shinjuku Line trains, some limited express services, and freight trains. However, in everyday usage the "Yamanote Line" refers to the entire 34.5 km loop line served by local trains. (This article uses the same definition.)

Service[edit]

Trains run from 04:26 to 01:18 the next day at intervals as short as 2.5 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 Ōsaki (which for timetabling purposes is the line's start and terminus) and sometimes Ikebukuro. Certain trains also start from Tamachi in the mornings and end at Shinagawa in the evenings. Trains which run clockwise are known as sotomawari (外回り?, "outer circle") and those counter-clockwise as uchi-mawari (内回り?, "inner circle"). (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 Line between Sendagaya and Ochanomizu.

The 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 "Japanese Bush Warbler green" (ウグイス色 uguisu-iro?).

Ridership[edit]

An estimated 3.68 million passengers [2] ride every day on Tokyo's Yamanote Line, with its 29 stations. For comparison, the New York City Subway carries 5.08 million passengers per day on 26 lines serving 468 stations,[3] and the London Underground carries 2.7 million passengers per day on 12 lines serving 275 stations.[4]

Name[edit]

"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 'mountain', no genitive suffix, and te 'hand', thus "mountain's hand" (means Hillside).

Yamanote-sen is officially written in Japanese without the kana no (の、ノ?), which makes its pronunciation ambiguous in print. The characters 山手 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." It was thus alternatively known as "Yamanote" and "Yamate" until 1971, when the Japanese National Railways changed the pronunciation back to "Yamanote." Some older people still refer to the line as the "Yamate Line".

In 1971, JNR changed all train line signage to specify the pronunciation of line names. This change is attributed to the opening of the Agatsuma Line, which could be incorrectly pronounced "Azuma" as the kana ga (が、ガ?) is omitted in its written name. As part of this change, JNR decided to adopt the Yamanote pronunciation, one reason being that there is a Yamate Station on the Negishi Line in nearby Yokohama.[citation needed]

History[edit]

The construction of the Yamanote Line and current JR lines
Yamanote Line in 1925

The Yamanote Line originated in 1885 with the construction of the Shinagawa Line (品川線 -sen?) between Shinagawa and Akabane, bypassing the then built up areas and providing the first north-south rail link through Tokyo. The top part of the loop between Ikebukuro and Tabata was completed in 1903 (known as the Toshima Line (豊島線 -sen?)) and following electrification in 1909 both lines were merged to become the Yamanote Line. The loop was not complete at this time, so trains generally inter-operated with the Chūō and Keihin-Tōhoku lines, traveling from Nakano to Tokyo Station, south to Shinagawa, then clockwise around the Yamanote Line to Tabata.

The loop was completed in 1925 with the opening of the section of track between Kanda and Ueno, providing a north-south link via Tokyo Station through the city's business centre. 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 from their terminal stations to the central districts of Tokyo, forcing to terminate services at stations on the line. This policy led to the development of new urban centers (新都心、副都心 shintoshin, fukutoshin?) around major transfer points on the Yamanote Line, most notably at Shinjuku and Ikebukuro (which are now the two busiest passenger railway stations in the world).

The contemporary Yamanote Line came into being in 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 Tabata. However, Yamanote Line trains continued to periodically use the Keihin-Tōhoku tracks, particularly on holidays and during off-peak hours, until rapid service trains were introduced on the Keihin-Tōhoku Line in 1988.

A major explosion on the Yamanote Freight Line in Shinjuku in 1967 led to the diversion of freight traffic to the more distant Musashino Line. To address severe undercapacity, the freight line was repurposed for use by Saikyō Line and Shōnan-Shinjuku Line trains, as well as certain limited express trains such as the Narita Express and some liner services. Likewise, there are currently plans to extend the Tōhoku Main Line to Tokyo Station to provide further relief on the busiest portion of the Yamanote Line today, the southbound segment between Ueno and Okachimachi.

Future[edit]

In January 2012, it was announced that the Yamanote line would get a new station, the first new station in 40 years. The distance between Shinagawa and Tamachi stations is 2.2 km, making it the longest stretch of track on the Yamanote Line by both distance and time (3 minutes). The new station will be constructed on top of the current 20-hectare railyard which is undergoing redevelopment by JR-East. The Yamanote Line and the Keihin Tohoku Line will be moved a bit to the east to be lined closer to the Shinkansen tracks. The area on the west side of the yard that will become available will be redeveloped with high-rise office buildings, creating an international business center with good connections to the Shinkansen and Haneda Airport. The construction of the new station is expected to start in fiscal 2014. This will bring the Yamanote line's total number of stations to 30 from 29.[5][6]

Rolling stock[edit]

Current[edit]

The line's services are operated exclusively by a fleet of 52 11-car E231-500 series EMUs, which were phased in from April 21, 2002.[7] 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,[8] and all trains were standardized with newly built four-door cars by 31 August 2011.[9] This was due to reduced congestion on the line as well as preparation for the installation of platform doors on all stations by 2017.[10]

The E231 series supports a new type of traffic control system, called digital Automatic Train Control (D-ATC), which will help reduce one round trip to a very short 58 minutes. The series also has 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 both Japanese and English) along with notification of delays on Shinkansen and other railway lines in the greater Tokyo area. The E231-500 series trains are based at Tokyo General Rolling Stock Centre near Ōsaki Station.
