Oedo Line Tokyo Subway 都営地下鉄大江戸線
Oedo Line Tokyo Subway
The Oedo Line operated by Toei is a large subway loop line around Tokyo that also has a long branch line to its north-west.
The Toei Ōedo Line is a Tokyo subway line that encircles the center of the metropolis, and with a branch from Tochōmae station extending north-west.
The above-ground JR Yamanote Line is Tokyo's other loop line. The western-most station for both lines is Shinjuku (ignoring the Ōedo Line's branch line). However, while the Yamanote Line's loop is stretched along its north-south axis, going all the way south to Shinagawa, the Ōedo Line's is stretched east-west, going all the way east to Kiyosumi-Shirakawa.
"Great Edo" Line
"Ōedo" means "Great Edo," Edo being the former name for Tokyo (in spite of the line's hub, Tochomae Station in Shinjuku, being well outside the city boundaries of old Edo).
The "Toei" indicates that it is operated by the Tokyo Metropolitan Bureau of Transportation, as opposed to "Metro" lines, run by Tokyo Metro Co., Ltd. (which, however is jointly owned by the Ministry of Finance and the Tokyo metropolitan government).
The Ōedo Line is the only Tokyo subway line with all stations underground. Being the last subway station to be completed, it is considerably deeper than the other lines, involving lots of stairs, escalators and elevators.
The Oedo Line is subway line no.12, its station numbers are prefixed with the letter E, and its color on subway maps is magenta.
Work began on the Oedo Line in 1986 (on the branch section, from Hikarigaoka), and was completed in 2000.
At 43.58 km long, the Oedo Line is the longest subway line in Japan. It was also Japan's most expensive subway line to build by far, costing approximately JPY 1.3 trillion - or over USD 12 billion as of the year 2000.

Tips for Riding the Ōedo Line
Here are some useful tips for using the Ōedo Line (and all other trains in Japan).
1. First buy a pre-paid smartcard, such as a Suica or Pasmo (if purchased in Tokyo, different if purchased elsewhere). They require a refundable 500 yen initial charge, but make subway use much easier than having to buy a paper ticket at a station whenever you ride a train. Simply touch the card for a second on the sensor at the ticket wicket as you pass through.
2. Identify in advance the number of the exit you will need to take at the destination station and ...
3. having identified that exit, board the car closest to that destination exit. You will save time (and be less likely to get lost) if you can board the car that will stop closest to the destination station exit you will leave from. There are charts for that purpose on the station wall, telling you the appropriate cars for each exit at each station, or you can ask a station attendant. "[Station name] no deguchi ni oriru no de, dono sharyō ni noreba ii desu ka".
4. Mind your manners. Don't eat or drink on the train, remove your backpack if you're standing, don't put luggage on the seat beside you, don't talk on your cell phone, and if you're talking to people, try and keep it subdued.
