Houses and small factories packed together, and a hot-spring bathhouse that opens at 6am
The closest neighborhoods in the same city.
Nishi-Kojiya is densely packed with houses and small factories (machikoba). Near Kojiya Station there's a bathhouse called Sachinoyu, which opens at 6am and uses natural hot spring water. On the east side of the station there's also a shopping street that crosses the railway tracks, occasionally used as a location for TV dramas and commercials.
Another shopping street, the Kojiya shopping street, extends south from Nishi-Kojiya to Haginaka 1- and 2-chome, where it crosses the Haginaka shopping street, forming this neighborhood's commercial area. Further south in Motohaneda, houses and factories are mixed together, and in recent years, as factories have closed, more and more apartment buildings have been built.
This neighborhood covers Nishi-Kojiya 1- and 4-chome, Haginaka 1- and 2-chome, Motohaneda 1- and 2-chome, and Minami-Kamata 3-chome; around 31,000 people lived here in 2020, about 250 per hectare.
From our street photos, daily shopping ranks 122nd out of 395 neighborhoods in Tokyo, near the top, and the strongest category for this neighborhood. There's a supermarket, a wholesale supermarket, and a home center within the neighborhood. Medical care and pharmacies rank 163rd, in the middle of the pack.
Kojiya Station is an elevated station, with the ticket gate at the Haneda Airport end; once inside, you can switch platforms within the station. Trains to Shinagawa and Yokohama depart from platform 2, and the next stop is Keikyu Kamata.
Cleanliness ranks 388th out of 395 neighborhoods in Tokyo, toward the bottom, and the weakest category for this neighborhood. Greenery ranks 383rd, also toward the bottom.
Motohaneda has no station of its own; it's about a 15-minute walk to Kojiya, Otorii, Anamori-inari, or Zoshiki.
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. About 99% of the points fall in the 0.5 to 3 meter range, with only 3 scattered points above 3 meters.
In Nishi-Kojiya, widespread flooding from a storm surge is expected to last at least 1 day but less than 3 days. Check Ota City's hazard map for your specific address.
The name Kojiya comes from the place name at the time the station opened: Oaza Kojiya, Haneda-machi, Ebara-gun. Oaza Kojiya roughly corresponds to today's Kita-Kojiya, Higashi-Kojiya, and Nishi-Kojiya; the town name "Kojiya" itself no longer exists, surviving only in the station, shopping street, and school names.
Today's Nishi-Kojiya was formed in 1964, when the residential address system (jukyo hyoji) was implemented, by merging parts of several towns including Kita-Kojiya-cho and Kojiya-cho. Haginaka was also renamed Haginaka 1- to 3-chome in the same year; Haginaka village itself split off from Haneda village much earlier, around 1693.

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.
