Ichigaya Station (JB 15 / Y 14 / N 09 / S 04) is a major interchange in central Tokyo straddling Chiyoda and Shinjuku wards, served by JR East's Chūō-Sōbu Line, Tokyo Metro's Yūrakuchō and Namboku Lines, and the Toei Shinjuku Line. JR East and Tokyo Metro use the spelling 市ケ谷 (large カ), while Toei uses 市ヶ谷 (small ヶ). The JR side opened on 6 March 1895 as a Kōbu Railway station and was nationalised on 1 October 1906; under the line-naming ordinance of 12 October 1909 it became part of the Chūō East Line, which was renamed the Chūō Main Line in 1911. The Eidan Yūrakuchō Line opened here on 30 October 1974, the Toei Shinjuku Line on 16 March 1980, and the Eidan Namboku Line on 26 March 1996; the two Eidan stations passed to Tokyo Metro when the authority was privatised on 1 April 2004. It is the only station in Japan with direct interchange ticket gates between three different railway operators — JR, Tokyo Metro and Toei.

Ichigaya is the only station in Japan with direct transfer ticket gates between all three of its operators — JR East, Tokyo Metro and Toei — each fitted with automatic transfer fare-adjustment machines, the Toei–Tokyo Metro gate here being the first in the country to receive one. The Namboku Line concourse holds an "Edo History Walking Corner" displaying stonework from the site of the Edo Castle outer moat together with Edo-period maps and archaeological exhibits.
