The Marunouchi Line is the second-oldest subway Line in Tokyo. Construction began before World War II, but the line opened after the war, in 1954. Near Myogadani, Korakuen, Ochanomizu, and Yotsuya, the line briefly runs above ground before returning underground. Compared with the Ginza Line, it uses slightly larger rolling stock, although the two lines are electrically compatible.
