Tokyo Station (東京駅, Tōkyō-eki) is a railway station in the Marunouchi business district of Chiyoda, Tokyo, Japan, near the Imperial Palace grounds and the Ginza commercial district. It is the main intercity rail terminal in Tokyo, the busiest station in Japan in terms of number of trains per day (over 3,000), and the fifth-busiest in Eastern Japan in terms of passenger throughput. It is the starting point and terminus for most of Japan's Shinkansen high-speed rail lines, and is served by many local and regional commuter lines of Japan Railways, as well as the Tokyo Metro network.
The station is linked by underground passageways to the Ōtemachi underground (subway) station complex served by the Tōzai, Chiyoda, Hanzōmon, and Mita subway lines. It is also possible to walk to the Nijūbashimae, Hibiya, Yūrakuchō, Ginza, and Higashi-ginza Stations completely underground (the last a distance of over 2 km), but these stations can usually be reached more quickly by train. Tokyo Station is also a major intercity bus terminal, with regular midday service to several cities in the Kantō region and overnight service to the Kansai and Tōhoku regions.
