The Tokyo subway is an integral part of the world's most extensive rapid transit system in a single metropolitan area, Greater Tokyo. While the subway system itself is largely within the city center, the lines extend far out via extensive through services onto suburban railway lines.
NetworksAs of June 2008, the entire network of Tokyo Metro, Tokyo Metropolitan Bureau of Transportation and Tokyo Waterfront Area Rapid Transit has 282 stations and 14 lines. The Tokyo Metro and Toei networks together carry a combined average of close to eight million passengers daily[1]. Despite being ranked first in worldwide subway usage, subways make up a small fraction of heavy rail rapid transit in Tokyo alone--only 282 out of 882 railway stations, as of 2007.[2] There are two primary subway operators in Tokyo:
In addition, the Tokyo Waterfront Area Rapid Transit (TWR) operates a single mostly-underground line with eight stations. The Yamanote Line is not a subway, but an above-ground commuter line operated by JR East. It acts as a key transportation artery in downtown Tokyo; therefore, it is often marked on Tokyo subway maps. Many above-ground and underground lines in the Greater Tokyo Area operate through services with the Tokyo Metro and Toei lines so that in a broader meaning they consist a part of the Tokyo subway network. The Yokohama Subway (and the planned Kawasaki Subway) also operate in the Greater Tokyo Area, but they are not directly linked to the Tokyo subway network. However, on special occasions (typically holiday weekends), the Tokyo Metro Hibiya Line and Namboku Line operate special Minato Mirai (みなとみらい号 Minatomirai-gō?) direct through services onto Yokohama's fully underground Minatomirai Line via the Tōkyū Tōyoko Line railway. From 2012, the Tokyo Metro Fukutoshin Line will also have regular through service to the Minatomirai Line. System administrationAll three subway systems are closely integrated with a unified system of line colors, line codes and station numbers. However, the separate administration of metro systems has these ramifications:
1995 Sarin AttackIn 1995, Aum Shinri Kyo, a doomsday cult, attacked the subway system with sarin nerve gas at Kasumigaseki Station and a few others, leading to 12 deaths and 1,034 people injured. See alsoReferences
