Since the 2000s, Indian engineers have moved in, and Indian restaurants and grocery stores have opened on the streets
The closest neighborhoods in the same city.
After the 2000s, Indians working mainly as IT engineers moved into this area — Japan had brought in Indian engineers to deal with the Y2K problem. As the Indian population grew, Indian restaurants and grocery stores opened in the neighborhood; at the India International School, founded in 2006, Japanese students make up about 40%.
Around 2000, the UR Urban Renaissance Agency also relaxed the move-in requirements for the danchi housing complexes in this area. In 2025, Edogawa City was home to 7,702 Indian residents, the second-largest foreign nationality in the City.
This neighborhood had a population of about 61,000 in 2020.
Nishi-Kasai has many vocational schools, so it's also a student town. South of the neighborhood is Kasai Rinkai Park, opened in 1989.
From our street photos, the neighborhood environment ranks 43rd out of 395 neighborhoods in Tokyo, putting it in the top tier. It ranks 199th for everyday shopping, in the middle tier.
The land readjustment left wide roads and a neat grid of blocks. The danchi complexes and parks in the former Kasai-oki area to the south (now Seishincho and Rinkaicho) were planned together and were selected for the "100 Selections of Japanese Townscapes"; Seishincho is within this neighborhood.
The station is an elevated station on the Tozai Line; public transit ranks 338th out of 395 neighborhoods in Tokyo. During morning and evening rush hours, it occasionally gets so crowded that you can't get on the train.
The next station toward central Tokyo is Minami-sunamachi, 2.7 km away — the longest stretch on the Tokyo Metro. Nishi-Kasai sits in a zero-meter zone, kept dry by levees.
Nishi-Kasai faced Tokyo Bay up until the latter half of the 20th century. When the Tozai Line opened in 1969, this area hadn't yet been developed, so no station was built here.
The Kasai-oki development project began in 1972, filling in the shallow waters offshore to create land, and from then on Nishi-Kasai was no longer on the coast. Land readjustment followed, giving us today's wide roads and neat grid of blocks.
Anticipating population growth, Nishi-Kasai Station opened in October 1979. Later, the widest part of the platform was widened from 6.25 meters to 8.5 meters.
The crowding problem is still being addressed: the next station, Minami-sunamachi, is being rebuilt with two platforms and three tracks; Tokyo Metro says the work will be completed in fiscal year 2031. Once it's done, a delay on one train should be less likely to drag down the ones behind it.
After the Yurakucho Line extension in the mid-2030s, the most crowded stretch of the Tozai Line is expected to ease up somewhat. South of the neighborhood, Tokyo Sea Life Park is being rebuilt, with a target opening in 2028.
Compared with the 395 Tokyo neighborhoods in this guide (scores 0–10)
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.
