A residential area where only Keikyu Local trains stop, with a shopping street running from the station to Toho-Idai-dori
The closest neighborhoods in the same city.
Omorimachi Station is an elevated station on the Keikyu Main Line, served only by Local trains. Walking from the station toward Toho-Idai-dori (Auxiliary Road No. 27), you'll find a shopping street between the station and this street. Both the Keikyu Main Line and Toho-Idai-dori run north-south through Omori-Nishi, with most of the area on both sides being residential.
Omori-Higashi to the east and Omori-Naka to the south are likewise mainly residential. This neighborhood covers Omori-Nishi 3-, 4-, and 5-chome, Omori-Naka 1-chome, Omori-Higashi 2- through 4-chome, and Chuo 3-chome, with a population of about 36,000 in 2020, or about 239 people per hectare.
Daily shopping ranks 114th out of 395 neighborhoods in Tokyo, near the top, with a shopping street right between the station and Toho-Idai-dori. Medical care and pharmacies rank 133rd, in the middle of the pack.
The station has two side platforms, with Heiwajima and Umeyashiki as neighboring stations. In fiscal 2024, the average daily ridership (boarding and alighting) was 21,817.
Public transit ranks 296th, and greenery ranks 381st, both toward the bottom.
TidyMap ran its own estimate, taking points roughly every 40 meters within the neighborhood on the Geospatial Information Authority of Japan's flood inundation hazard map (maximum assumed scale). Over 90% of the points fall within the projected flood zone, mostly in the 0.5 to 3 meter range; all sample points in Chuo 3-chome fall in the 0.5 to 3 meter range.
In the Tokyo Metropolitan Government's regional earthquake risk survey published in 2022, Chuo 3-chome's fire risk and overall risk were both rated at level 5, the highest of the five levels. To check the flood depth at your own location, please use Ota City's hazard map.
When the station opened in 1901, it was called Sanya Station, later renamed Omori-Sanya Station. It was suspended after war damage in 1945, and abolished in 1949 on the grounds that the area had no prospect of recovery, not reopening under the name Omorimachi Station until 1952.
Construction to elevate the line began in 2001 and was completed in 2012. The name of Omori-Naka, to the southeast of the station, comes from the former Omori Ward Office, which once stood near what is now the Omori Police Station.

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.
