Four train lines meet by the fishing pond at the outer moat, with the Nihon Ki-in head office right outside the station
The JR platforms at Ichigaya Station run right alongside the outer moat of Edo Castle, which still has a fishing pond in it. This station serves four lines—JR, two Tokyo Metro lines, and the Toei Shinjuku Line—and the ticket gates of all three operators connect with each other; Ichigaya is the only station in Japan where this is the case. Gobancho, in front of the JR station, is home to the head office of the Nihon Ki-in, the governing body of the go world, which moved here in 1971. Cross the outer moat and head up the slope into Shinjuku Ward, and the Ichigaya Sadoharacho area is mostly low-rise apartments; the further into 3-chome you go, the more detached houses there are.
3-chome, along with neighboring Ichigaya Funagawaracho and Haraikatamachi, was originally daimyo estates, and the area is still considered an upscale residential district. Down the slope, Ichigaya Tamachi has campus buildings for Hosei University, Chuo University, and Musashino Art University. Based on our street photos, this neighborhood ranks 9th out of 219 Tokyo neighborhoods for cleanliness and 21st for street environment, both near the top. With four lines meeting at the same station, public transit also ranks 67th, in the top part.
On the Chiyoda Ward side, there are more offices than homes. Gobancho has about 1,000 residents, and in 2021 about 6,500 people worked there; Sanbancho has about 4,200 residents, and about 9,700 people worked there. The large site to the west occupied by the Ministry of Defense's Ichigaya district is not included in the neighborhood. Almost no water flows into the outer moat, and when summer temperatures rise and the water sits still for a long time, blue-green algae can grow in large quantities.
In 1479, Ota Dokan built Edo Castle and invited a divided spirit from Tsurugaoka Hachimangu in Kamakura to guard the western side; this was the origin of Ichigaya Kamegaoka Hachimangu. In the early Edo period, the hatamoto guard unit called the Obangumi, responsible for protecting the shogun, lived in this area, which is where the name Bancho comes from. Around 1636, once the outer moat was dug, the shrine was moved to its present location. In 1874, the Imperial Japanese Army Academy opened on Ichigaya-dai, to the west, outside the neighborhood, and after the war its old main lecture hall became the courtroom for the Tokyo Trials. In 1895, Ichigaya Station on the Kobu Railway opened.
In March 2026, the Tokyo Metropolitan Government drew up an implementation plan to clean up the outer moat, connecting Tamagawa Josui to the outer moat, with water expected to start flowing in from the mid-2030s. Under the 2022 basic plan, water will be channeled into Ichigaya-bori, Shinmitsuke-bori, and Ushigome-bori, replacing the moat water about once every 5 days.

Hospitals with inpatient beds (2020 data), public elementary and junior high schools whose catchment covers this area, high schools and universities within 1 km, stations, parks of 1 ha or more, and large shopping malls and department stores. Many Tokyo junior high students attend private schools, so junior high catchments are only a guide.
