The Chūō Line (Rapid) is the name given to rapid services on the eastern section of the Chūō Main Line operated by the East Japan Railway Company between Tokyo and Takao stations. Some services continue to Otsuki.

Tōkyō Station is a major railway station in Chiyoda, Tokyo, Japan. The original station is located in Chiyoda's Marunouchi business district near the Imperial Palace grounds. The newer Eastern extension is not far from the Ginza commercial district. Due to the large area covered by the station, it is divided into the Marunouchi (west) and Yaesu (east) sides in its directional signage.
