The Toei Oedo Line (都営地下鉄大江戸線 Toei Chikatetsu Ōedo-sen) is a subway line in Tokyo, Japan operated by the Tokyo Metropolitan Bureau of Transportation (Toei). The Oedo Line was first proposed in 1968 as an incomplete loop line from Shinjuku around northern and eastern Tokyo to Azabu. Oedo line commenced full operations on December 12, 2000; using the Japanese calendar this reads "12/12/12" as the year 2000 equals Heisei 12. The Oedo line is completely underground, making it the second-longest railway tunnel in Japan after the Seikan Tunnel. On Oedo line map and signboards, the line is shown in "magenta" (O). Stations carry the letter E followed by a two-digit number.
The Oedo Line is Tokyo first linear motor metro line (and the second in Japan after the Nagahori Tsurumi-ryokuchi Line in Osaka), which allows Oedo line to use smaller cars and smaller tunnels. These putative cost savings were, however, offset by the need to build the line very deep (as low as 48 meters below ground at points) through central Tokyo, including three underground crossings of the Sumida River as its mentioned in Oedo line map. Originally budgeted at ¥682.6 billion and 6 years, the construction ended up taking nearly 10 years and estimates of the final cost of construction range from the official ¥988.6 billion to over ¥1,400 billion yen, making Oedo line the most expensive subway line ever built. (Yokohama Minato Mirai Line, however, was even costlier if measured per kilometer.)
The Oedo Line runs in a loop around central Tokyo before branching out towards Nerima in the western suburbs, meaning the line is shaped like a figure of 6 lying on its side as you can see in Oedo line map. Oedo line is not a true loop line: trains from the western Hikarigaoka terminus run anticlockwise around the loop and terminate at the intermediate Tochōmae Station facing towards Hikarigaoka, and vice-versa. The full 40.7 km trip from Tochōmae around the loop and onward to Hikarigaoka takes 81 minutes. Oedo line trains operate once every three to five minutes during rush hours, and once every six minutes during off-peak weekday hours, weekends and holidays.
