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.

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).
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:
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.

The Tokyo Metro is a major rapid transit system in Tokyo, Japan, operated by the Tokyo Metro Co. With an average daily ridership of 6.84 million passengers, the Tokyo Metro is the larger of the two subway operators in the city; the other being the Toei Subway, with 2.85 million average daily rides.
The Keisei Electric Railway Company, Ltd. is a major private railway in Chiba Prefecture and Tokyo, Japan. The name Keisei is the combination of the kanji 京 from Tokyo and 成 from Narita, which the railway's main line connects. The combination uses different readings than the ones used in the city names. The railway's main line runs from Tokyo to Narita and the eastern suburb cities of Funabashi, Narashino, Yachiyo, and Sakura. Keisei runs an airport limited express train called the Skyliner from Ueno and Nippori to Narita International Airport.
Keikyu Corporation, also known as Keihin Kyūkō (京浜急行) or, more recently, Keikyū (京急), is a private railroad that connects inner Tokyo to Kawasaki, Yokohama, Yokosuka and other points on the Miura Peninsula in Kanagawa Prefecture. It also provides rail access to Haneda Airport in Tokyo. Keihin (京浜) means the Tokyo (東京) - Yokohama (横浜) area. The company's railroad origins date back to 1898, but the current company dates to 1948. The railway pioneered Kantō region's first electric train and the nation's third, after Hanshin Electric Railway and Nagoya Electric Railway (Meitetsu) with the opening of a short 2 km (1.2 mi) long section of what later became the Daishi Line in January 1899.
