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.

Marunouchi (丸の内) is a commercial district located in Chiyoda, Tokyo, Japan. Situated between Tokyo Station and the Imperial Palace, the name, meaning "inside the circle", derives from its location within the palace's outer moat. It is also Tokyo's financial district and the country's three largest banks are headquartered there.
