The Keiyo Line, which opened in 1990, is a relatively young line within JR East, connecting Chiyoda-ku, Tokyo, with Chiba City, Chiba Prefecture. Except for the underground section between Tokyo Station and Etchujima Station, the entire line is characterized by running on elevated tracks along Tokyo Bay. The area along the line is being redeveloped as reclaimed land on Tokyo Bay, and in addition to new towns, theme parks, large shopping malls, and offices are towering above the area.A delta line (connecting line) is provided from Nishi Funabashi Station on the Musashino Line to Ichikawa Shiohama Station and Minami Funabashi Station on the Keiyo Line, and Musashino Line trains operate directly to the Keiyo Line.
