Route map

The Namboku Line (南北線, Nanboku-sen^?) is a subway line owned and operated by Tokyo Metro in Tokyo, Japan. Its name literally means South-North Line. The line runs between Meguro in Shinagawa and Akabane-Iwabuchi in Kita. The Namboku Line was referred to as Line 7 during the planning stages, thus the seldom-used official name is Line 7 Namboku Line (7号線南北線, Nana-gō-sen Namboku-sen^?).

Overview [edit]

Trains run through onto the Tokyu Corporation's Meguro Line for Hiyoshi and the Saitama Railway's Saitama Rapid Railway Line for Urawa-Misono. The portion between Shirokane-Takanawa and Meguro is shared with the Tokyo Metropolitan Bureau of Transportation (Toei) Mita Line.

The right-of-way and stations between Shirokane-Takanawa and Meguro are shared with the Toei Mita Line. Under an agreement between Tokyo Metro and the Tokyo Metropolitan Government, the fare for this section is calculated on the Toei fare system for passengers traveling to stations on the Mita Line past Shirokane-Takanawa, on the Metro fare system for passengers traveling to stations on the Namboku Line past Shirokane-Takanawa, and on the system "most beneficial to the passenger" (presently the Metro schedule) for travel solely on the shared sector.

On maps, diagrams and signboards, the Namboku Line is shown using the color "emerald" (▉), and its stations are given numbers using the letter "N".

History [edit]

The 21.3 km Namboku Line is one of Tokyo Metro's newest lines, featuring advanced technology including full automatic train operation and platform screen doors. Although the line was originally proposed in 1968, construction did not begin until the 1980s, partly due to the right-of-way to Meguro with Tokyo Metropolitan Bureau of Transportation's Mita Line. The first segment from Komagome to Akabane-Iwabuchi opened on November 29, 1991.

The line initially operated with four-car EMUs. Upon its extension to Yotsuya in March 1996, the formations were extended to six cars. All stations are able to accommodate eight-car trains, but this length is not yet used.

The extension to Tameike-Sannō was completed in September 1997, and the last stretch from Tameike-Sanno to Meguro was completed on September 26, 2000, when through service to the Tōkyū Meguro Line started. Through service with the Saitama Rapid Railway line commenced when it opened in March 2001 and accommodated traffic to and from Saitama Stadium during the 2002 World Cup.
