Tokyo Metro
El metro de Tokio
Tokyo Metro and Toei Subway operate the subways in Tokyo. At the entrance to each station, you will see the subway sign and the name of the subway station. Be sure to remember the station name, number and line color (circular colored outline) of the subway line you want to ride. You will see the combination of a letter (representing the line) and a number (representing the station) within a circular colored outline (representing the color of the line), which is called a station number.

Train fares range from ¥170 to ¥310 depending on how far you travel. A one day pass for unlimited use of Tokyo Metro on one calendar day is available for ¥710, but note that special passes for visitors are sold at Narita Airport and Haneda Airport for only ¥600 for a 1-day version and ¥980 for a 2-day version.
