The Tokyo Metro Marunouchi Line (東京地下鉄丸ノ内線, Tōkyō Chikatetsu Marunouchi-sen^?) is a subway line of the Tokyo Metro system in Tokyo, Japan. The line runs in a U-shape between Ogikubo Station in Suginami and Ikebukuro Station in Toshima, with a branch line between Nakano-Sakaue Station and Hōnanchō Station. The official name is Line 4 Marunouchi Line (4号線丸ノ内線, Yon-gōsen Marunouchi-sen^?).

Overview

The Marunouchi Line is the second line to be built in the city, and the first one constructed after the Second World War. The route is U-shaped, running from Ogikubo Station in the west of the city via the commercial and administrative district of Shinjuku through to the Marunouchi commercial center around Tokyo Station, before turning back and heading to Ikebukuro.

The Marunouchi Line is served by Tokyo Metro 02 series rolling stock in six-car trains on the main line, and three-car trains on the Hōnanchō branch. The main line is the most frequent subway line in Tokyo, with trains running at intervals of 1 minute 50 seconds during peak hours. In spite of such high-frequency service, according to a 2008 survey by the Ministry of Land, Infrastructure, Transport and Tourism the Marunouchi Line is one of the most crowded railway lines in Tokyo, running at 157% capacity between Shin-ōtsuka and Myōgadani stations.^[1] Its age and relatively short train length has made it one of the most crowded lines in Tokyo, although the 2000 opening of the Toei Ōedo Line has relieved the problem somewhat. In response to crowding, Tokyo Metro upgraded all stations with chest-high platform doors and began driver-only operation on March 28, 2009. The Hōnanchō branch switched to driver-only operation in July 2004.^[2]

Due to the age of the Marunouchi Line and the relative shallowness at which it runs, at several points in central Tokyo trains run at or above ground level. These include Yotsuya Station, the Kanda River near Ochanomizu Station (see image), and between Kōrakuen and Myōgadani stations.

On maps, diagrams and signboards, the line is shown using the color "red" (▉). Its stations are given numbers using the letter M; Hōnanchō branch line stations carry a lowercase m.

History

The Marunouchi Line is the second subway line to be built in the city, and the first to be constructed after the Second World War. Its design similar to that of the Ginza Line, the oldest subway line in Tokyo. Both lines are standard gauge and utilize third-rail power, unlike most Tokyo subway lines.

The first section was opened between Ikebukuro and Ochanomizu on 20 January 1954. The subsequent progress of the line is as follows:

• Ochanomizu to Awajichō: March 1956
• Awajichō to Tokyo: July 1956
• Tokyo to Nishi-Ginza (now Ginza): December 1957
• Nishi-Ginza to Kasumigaseki: October 1958
• Kasumigaseki to Shinjuku: March 1959
• Shinjuku to Shin-Nakano/Nakano-Fujumichō (not Nishi-Shinjuku): February 1961
• Shin-Nakano to Minami-Asagaya (not Higashi-Kōenji): November 1961
• Minami-Asagaya to Ogikubo: January 23, 1962
• Nakano-Fujimichō to Hōnachō: March 23, 1962
• Nishi-Ginza becomes part of Ginza when Hibiya Line reaches there: August 1964
• Higashi-Kōenji opens (between Shin-Nakano and Shin-Kōenji) : September 1964
• Prior to April 1, 1972 the section west of Shinjuku was known as the Ogikubo Line. The Marunouchi Line name applied to the whole line after that date.
• Nishi-Shinjuku opens (between Shinjuku and Nakano-Sakaue) May 1996.
