Every train on the Toyo Rapid Railway (other then depot workings between Yachiyo-Midorigaoka and Toyo-Katsutadai) operates a through service with the Tokyo Metro Tōzai Line.

As such, the service type only refers to the stops made on the Tokyo Metro Tōzai Line.

Operates between Tōyō-Katsutadai and Nakano (the western terminus of the Tōzai Line), with some services extending to Mitaka.

Due to congestion on tracks, on March 14, 2009, the timetable changed to have 4 evening "up" bound Tōyō Rapid trains, thus the "down" service towards Tōyō-Katsutadai was abolished.

[1] Limited-stop "Toyo Rapid" (東葉快速, Tōyō Kaisoku) services were introduced on the line from the start of the 4 December 1999 timetable revision.
