Katsushika City's first arcaded shopping street, running from the south exit straight across the boundary into Edogawa City
The closest neighborhoods in the same city.
In front of the station's south exit is the Lumiere shopping street, with about 140 shops.
The shopping street runs 420 meters long, and is the first shopping street in Katsushika City to have an arcade. It extends from Shin-Koiwa 1-chome in Katsushika City all the way to Matsushima 3-chome in Edogawa City, and the streets around the south exit blend into Matsushima as well.
On the north exit side is the campus of Tokyo Seiei College, and along "Daigaku-dori," the street leading to Kuramaebashi-dori, there are mostly restaurants.
Both the Sobu Rapid Line and the Local trains on the Chuo-Sobu Line stop at this station. In fiscal 2024, average daily boardings were over 73,000, the highest among stations in Katsushika City that have no other lines to transfer to.
The station is also a bus hub: from the south exit, buses run to Nishi-Kasai and Kasai; from the north exit, buses run to Ayase, Kameari, and Ichikawa.
For daily shopping, this neighborhood ranks 156th out of 395 neighborhoods in Tokyo, and for healthcare it ranks 218th — the two highest-ranked categories for this neighborhood, both in the middle of the pack.
This neighborhood has only this one JR station, and for public transit it ranks 369th out of 395 neighborhoods, in the lower range. Based on our street photos, greenery ranks 361st, also in the lower range.
This area is alluvial lowland on the east bank of the Arakawa and Nakagawa rivers, and Katsushika City has large areas at zero meters above sea level. A heavy rainstorm in September 2014 nearly flooded the area around the station.
The station's predecessor was the Shin-Koiwa signal station, set up in 1926, which was only upgraded to a full station in July 1928. At the time, the local place name was Komatsu, and residents wanted the station to be named "Shimofusa-Komatsu," but the tickets and station signs had already been printed, so it was never changed.
Later, even the name of the town followed the station and became Shin-Koiwa; before the residential address system was introduced, this area was called Shimo-Komatsu-cho and Hirai-Nakamachi.
Redevelopment of the south exit area received final urban planning approval in August 2021, covering two blocks of Shin-Koiwa 1-chome plus the south exit station plaza, about 1.5 hectares. The tallest building will be about 160 meters tall, with 39 floors above ground and about 543 units, scheduled for completion in fiscal 2032.
As for the shopping street's arcade, the section within the station plaza is being torn down; Katsushika City's fiscal 2024 subsidy records already include this demolition project.

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.

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.
