142 JR East stations inside Tokyo Metropolis. Stations served by several lines, such as Tokyo and Shinjuku, count once.
The Yamanote, Keihin-Tohoku, Chuo Rapid, Chuo-Sobu Local, Sobu Rapid, Yokosuka, Tokaido, Saikyo, Keiyo, Joban, Utsunomiya/Takasaki, Ome, Itsukaichi, Hachiko, Nambu, Musashino and Yokohama lines: 18 in all.
They are left out: lines leaving Tokyo are cut at the border. The Yokohama Line, for example, splits into Naruse–Machida and Aihara–Hachioji.
