From the revised timetable on the 4 December 1999, the "Toyo Rapid" service was created. It stopped at Nishi-Funabashi, Kita-Narashino, Yachiyo-Midorigaoka and Tōyō-Katsutadai. 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. Due to passenger counts increasing on stops that the Tōyō Rapid did not stop at, the Tōyō Rapid service was completely abolished on the March 14 2014 timetable change.
