HOME ＞ Subways in Japan
Japan's first subway line, a part of present Ginza Line of Tokyo Metro between Asakusa and Ueno, was opened in December 1927 with a distance of only 2.2km. Today, after 86 years Japan's subway network total is almost 750 kilometers in 9 cities and subways have become a core means of transport in these cities. There are two subway operators in Tokyo, One is Tokyo Metro and the other Toei (Tokyo Metropolitan Government).
The history of subway in Japan can roughly be divided into four stages; 1) an introduction era for some 25 years up to 1950, during which one line each was opened in Tokyo and Osaka. 2) an era of rapid growth in the next 20 years up to 1970 when subway networks expanded in these two cities and also in Nagoya, 3) an era of nationwide introduction over the next 20 years up to 1990, when subway appeared also in other major cities, from Sapporo in the north to Fukuoka in the south and then 4) the last decade an era of maturity, in which some existing lines received overall renovation and linear-induction motor system was chosen for some new lines.
