Five lines meet at a station straddling three wards; up Kudanzaka, a famed cherry-blossom spot
Iidabashi Station sits at the junction of three wards: the JR and Tozai lines are in Chiyoda Ward, the Yurakucho and Namboku lines are in Shinjuku Ward, and the Toei Oedo Line is in Bunkyo Ward. Five lines meet here, and public transit ranks 25th out of Tokyo's 193 neighborhoods, putting it near the top. The new JR west exit, opened in 2020, was built within the historic site area of the ruins of Edo Castle's outer moat; its eaves curve upward in the style of Japanese architecture, and the 2F level has a deck for viewing the outer moat. Right outside the west exit is Fujimi, an area where universities, high schools, and vocational schools cluster, and 2-chome also has several large hospitals.
South of Fujimi, at the top of Kudanzaka is Yasukuni Shrine, which was called Tokyo Shokonsha when it was founded in 1869; its grounds are a famous spot for cherry blossom viewing. Down the slope, next to Kudanshita Station is Kudan Kaikan, which was called Gunjin Kaikan when completed in 1934; now part of its exterior wall has been preserved and it has been rebuilt into a 17-storey mixed-use building. From our street photos, this neighborhood ranks 10th for cleanliness and 12th for sidewalks, both near the top in Tokyo.
Most of Kudan-kita 2-chome and 3-chome consists of the approach and grounds of Yasukuni Shrine, plus schools and Hosei University, so there aren't many homes there. In 1966, Kudan was split into north and south halves by Yasukuni-dori; the neighborhood association is still run jointly by both sides, but the festivals are split: 1-chome and 2-chome belong to Tsukudo Shrine, while 3-chome and 4-chome belong to Hie Shrine. Kudan-kita 4-chome and Kudan-minami 3-chome and 4-chome, on the Ichigaya side, are not included in this neighborhood.
Tsukudo Shrine, which enshrines Taira no Masakado, is said to have been founded in 940, originally near the Masakado-zuka mound in Otemachi. In 1881, a new bridge was built over the outer moat, and since it led to Iidamachi, it was named Iidabashi. In 1928, the Railway Ministry discontinued passenger service at Ushigome Station and Iidamachi Station, and set up a new station between the two, keeping the bridge's name. The town name "Kudan" first appeared in 1933, and the following year Gunjin Kaikan (later Kudan Kaikan) was completed. Tsukudo Shrine burned down entirely in the air raids of 1945, and in 1954 it was relocated to its current site on Kudan-nakazaka.
The Tokyo Metropolitan Government approved the formation of a redevelopment association on November 10, 2025, for the roughly 0.6-hectare area of Kudan-minami 1-chome next to Kudanshita Station. The plan includes a station-front plaza directly connected to Kudanshita Station. The rights conversion plan is scheduled to be approved in fiscal year 2026, with construction starting in fiscal year 2028 and completion in fiscal year 2033; the actual schedule will depend on future announcements.
