Nori wholesalers once lined the old Tokaido here; today it's the Mihara-dori shopping street
The closest neighborhoods in the same city.
Omori-Honcho, next to the station, was originally a shopping street along the old Tokaido (now Mihara-dori), with many nori wholesalers, which is how the town got its name. The Mihara-dori shopping street is still there today. Further south in Omori-Higashi, the Uchikawa River flows east-west, and the area is mainly residential.
Heiwajima Station is in Omori-Kita 6-chome; the station name comes from Heiwajima, the reclaimed island to the east, though the station itself is not on the island. The island is mainly logistics centers and warehouses, with only 241 residents in 2024; the homes in this neighborhood are all on the Omori side of the station.
This neighborhood covers Omori-Kita 6-chome, Omori-Honcho 2-chome, Omori-Higashi 1-chome, and Omori-Nishi 1- and 2-chome. In 2020, about 28,000 people lived here, roughly 253 per hectare.
Public transit ranks 208th out of 395 neighborhoods in Tokyo, and daily shopping ranks 221st; both fall in the middle of the pack.
The station is an elevated station on the Keikyu Main Line, with 2 island platforms and 4 tracks; Kaitoku Limited Express trains don't stop here, but Tokkyu Limited Express, Express and Local trains do. Local trains let faster trains pass here, and also connect with them here.
In fiscal 2025, average daily boardings and alightings were 46,335, the highest among Keikyu stations where the Kaitoku Limited Express doesn't stop.
Based on our street photos, greenery ranks 336th and street cleanliness ranks 374th, 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 at 0.5 to 3 meters, with the rest under 0.5 meters; only in Omori-Higashi 1-chome are about 20% of the points outside the zone.

When the station opened in 1901, it was called Sawada Station; Sawada was the name of the local aza (subdivision) at the time, and Sawada-dori and the Sawada intersection still remain nearby today. In 1939, the Tokyo government obtained permission for land reclamation, creating the Keihin District 2 reclaimed land; after completion in 1967, the town was officially named Heiwajima.
The station was renamed Heiwajima Station in 1961, taking the common name of this reclaimed land. In 1970, the down platform was elevated, making this a fully elevated 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.
