The low level is served by the Sōbu, Tōzai and Tōyō Rapid Railway Lines.

Platform 6 is mainly used for terminating Tōzai Line trains (to Toyocho, Nihombashi, Otemachi and Nakano), although it is used for through services in peak hours.

The high-level station opened on October 2, 1978, when platforms 9 and 10 (presentday 11 and 12) started being used as the terminus of the Musashino Line.

[citation needed] The next part of the Keiyō Line (Shin-Kiba to Nishi-Funabashi and Minami-Funabashi) opened on December 1, 1988.

The station facilities of the Tozai Line were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.
