Tokyo Metro Ginza Line

On maps, diagrams and signboards, the line is shown using the color orange, and its stations are given numbers using the letter "G".

[4] Upon its opening, the line was so popular that passengers often had to wait more than two hours to ride a train for a five-minute trip.

The Great Depression slowed down construction, but the line finally reached its originally planned terminus of Shimbashi on June 21, 1934.

The two lines began through-service interoperation in 1939 and were formally merged as the Teito Rapid Transit Authority ("Eidan Subway" or "TRTA") in July 1941 in accordance with the Land Transport Business Coordination Law [ja], related to the State General Mobilization Law.

The line, station facilities, rolling stock, and related assets were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.

Since April 2012,[10] the Ginza Line uses a fleet of 40 six-car Tokyo Metro 1000 series EMUs which have a maximum speed of 80 km/h (50 mph).

Cars are stored and inspected at Shibuya Depot located after Shibuya Station and at Ueno Inspection Division (上野検車区, Ueno-kensha-ku), a facility located northeast of Ueno Station with both above-ground and underground tracks.
