The Toei Asakusa Line (都営地下鉄浅草線, Toei Chikatetsu Asakusa-sen) is a subway line in Tokyo, Japan, operated by the municipal subway operator Toei Subway. The line runs between Nishi-magome in Ōta and Oshiage in Sumida. The line is named after the Asakusa district, a cultural center of Tokyo, under which it passes.

The Asakusa Line was the first subway line in Japan to offer through services with a private railway. Today, it has more through services to other lines than any other subway line in Tokyo. Keikyu operates through trains on the Keikyu Main Line to Misakiguchi and the Keikyu Airport Line to Haneda Airport Domestic Terminal. The Keisei Electric Railway operates through trains on the Keisei Oshiage Line to Inba-Nihon-Idai and the Keisei Main Line to Narita Airport Terminal 1, and the Shibayama Railway runs trains via the Keisei Main Line and the Shibayama Railway Line to Shibayama-Chiyoda. Via its through services with Keisei and Keikyu, the Asakusa line is the only train line that offers a direct connection between Tokyo's two main airports.

The Asakusa Line is often split into two routes: Oshiage–Sengakuji and Sengakuji–Nishi-magome; only some trains make all station stops on the line, as many trains travel on the Keikyu Main Line south of Sengakuji.

On maps and signboards, the line is shown in the color rose. Stations carry the letter "A" followed by a two-digit number inside a more reddish vermilion circle.

Services

Local (普通 futsū) trains operate between Nishi-Magome and Sengakuji approximately every ten minutes and are timed to connect to Keikyu through service trains at Sengakuji.
Rapid service (快速 kaisoku) trains operate between Nishi-Magome and Keisei Sakura Station approximately every twenty minutes. They make all station stops on the Asakusa Line.
Limited Express (快特 kaitoku) trains operate approximately every twenty minutes. They generally use Keikyu rolling stock and have a southern terminus at Misakiguchi Station or Keikyu Kurihama Station. They operate as Limited Express trains only on the Keikyu line, and provide local service on the Asakusa Line and Keisei Oshiage Line. Their northern terminus is generally either Aoto Station or Keisei Takasago Station, but select trains operate to Narita International Airport.
Limited Express (快特 kaitoku) trains operate approximately every twenty minutes and make all stops (local service) on the Asakusa Line, providing Limited Express service on the Keikyu line between Sengakuji and Haneda Airport Domestic Terminal. Their northern terminus is usually either Inzai-Makinohara Station or Inba-Nihon-Idai Station on the Hokuso Railway.
Airport Limited Express (エアポート快特 eapōto kaitoku) trains operate approximately every twenty minutes, and skip certain stations while operating on the Asakusa Line. Their northern terminus alternates between "Access Express" (アクセス特急 akusesu tokkyū) service to Narita International Airport and Limited Express service to either Aoto or Takasago. The total travel time from Haneda Airport to Narita Airport on this train is approximately one hour and 46 minutes.

Rolling stock

A variety of rolling stock is in use due to the large number of through service operators on the line, all of which use standard gauge tracks and 1,500 V DC electrification via overhead lines. Currently, six operators run trains onto the Asakusa Line, the most of any Tokyo subway line, and the line is unique as the only subway line in Tokyo with through services onto standard gauge railways (all other through services are with narrow gauge lines).

History

The Toei Asakusa Line was the first subway line constructed by the Tokyo Metropolitan Government. The line number is Line 1, because it was technically the first subway line in Tokyo to be planned in the 1920s as an underground route connecting the Keikyu and Keisei Electric Railway via Shinagawa, eventually allowing for through trains between these two railways. In its original plan form, the line would have actually bypassed Asakusa Station entirely. However, the plan was changed to take advantage of the existing Tobu Isesaki Line (section now named as the Tobu Skytree Line) and Tokyo Metro Ginza Line connections at Asakusa.

Construction of this line began on 27 August 1956 after years of delays, and the initial 3.2 km (2.0 mi) segment between Oshiage and Asakusabashi opened on 4 December 1960. The line then opened in stages from north to south:

May 1962: Asakusabashi to Higashi-Nihombashi
September 1962: Higashi-Nihombashi to Ningyōchō
February 1963: Ningyōchō to Higashi-Ginza
December 1963: Higashi-Ginza to Shimbashi
October 1964: Shimbashi to Daimon
June 1968: Daimon to Sengakuji (Through service with Keikyū begins)
15 November 1968: Sengakuji to Nishi-Magome

The line was named Asakusa Line on 1 July 1978.^[3]

From 1998 to 2002, the Asakusa Line was used as part of a rail connection between Tokyo's two major airports, Haneda and Narita. While a few trains still run between the airports, the service has greatly diminished in frequency since 2002.^{[citation needed]}

In 2005, a research group of government, metropolitan and railway company officials proposed that the Asakusa Line be connected to Tokyo Station via a spur to the north of Takarachō Station. This would provide Tokyo Station's first direct connection to the Toei subway network. It would also make it possible to reach Haneda Airport in 25 minutes (versus 35 minutes today) and Narita Airport in 40 minutes (versus 57 minutes today).^[4] This plan has yet to be finalized or formally adopted. Authorities are re-considering a similar plan as part of the infrastructure improvements for the 2020 Summer Olympics; the proposed line would cut travel time to Haneda from 30 minutes to 18 minutes, and to Narita from 55 minutes to 36 minutes, at a total cost of around 400 billion yen.^[5]
