Public housing built on top of a train depot, with hillside residential lanes on the plateau to the south
The closest neighborhoods in the same city.
The large area next to the east exit of Nishidai Station is the Shimura Rolling Stock Depot for the Mita Line, about 137,000 square meters. In 1970, the Tokyo Metropolitan Government built an artificial deck over the depot, then built the Toei Nishidai Apartments on top of it—so the trains park right beneath the homes.
Heading south into Nishidai, the slopes increase, and it's mostly residential. One theory is that the place name comes from the westernmost plateau as seen looking west from Shimura Castle.
This neighborhood covers Takashimadaira 9-chome, where the station is located, Takashimadaira 1-chome just outside the west exit, and Nishidai 1- and 2-chome further south. In 2020, about 25,000 people lived here, roughly 169 per hectare.
For everyday shopping, this neighborhood ranks 125th out of 395 neighborhoods in Tokyo, in the upper range—the highest-ranked item for this neighborhood. There's a supermarket south of the station, and Takashimadaira Chuo General Hospital is right outside the west exit.
The Mita Line runs south through Sugamo to connect with the Yamanote Line, then on to Otemachi and Hibiya, all without a transfer.
Nishidai Park, south of the station, has been known since the 1970s for its forest exercise equipment.
From our street photos, buildings rank 370th out of 395 neighborhoods in Tokyo, in the lower range—the weakest item for this neighborhood. Sidewalks rank 274th, also in the lower range.
Itabashi City's Arakawa flood scenario assumes 632 mm of rain falling over 72 hours across the Arakawa river basin. Based on our own calculations using points taken roughly every 40 meters across the neighborhood on the Geospatial Information Authority's flood map, about 75 percent of the points fall within the expected flood zone.
The whole of Takashimadaira 1- and 9-chome lies within the neighborhood, mostly at depths of 3 meters or more. Further south, about half of Nishidai 2-chome is affected, mostly at depths of 0.5 to 3 meters; on the plateau, less than 10 percent of Nishidai 1-chome is affected.
The City's flood handbook says you should only consider staying home if your house is sturdy, has floors above the flood level, and the water will drain within 3 days. Otherwise, go to friends or relatives' homes or an evacuation shelter before the trains stop running. The City's web-based hazard map lets you look up flood depth by town and chome.
In 1961, Daito Bunka University moved from Ikebukuro to this area, then still called Shimura Nishidai-cho. In 1968, Line 6, the predecessor of the Mita Line, opened, and the depot and Nishidai Station both opened that same year.
The station took its name from the old place name, but after later redistricting, the area around the station was renamed Takashimadaira. The town now called Nishidai actually lies about 500 meters south of the station.
In 1973, the Toei public housing built on the artificial deck above the depot was completed.

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.
Maps show the shops and the sights. What a street is like, you only know by walking it. TidyMap uses AI street imagery analysis and public facility data to turn each area's street environment and everyday convenience into something you can compare. Search an address and look at the street outside first.
How to read it: yellow = poor, blue = good; grey = not enough data
TidyMap rates the street environment and everyday convenience. It does not assess the home itself, safety, noise or actual living experience. Street environment scores use AI assessments of imagery; convenience scores use public facility data.
