About 50,000 Japanese irises bloom on the Edogawa riverbank, with Chiba just across the water
The closest neighborhoods in the same city.
Walk 5 minutes from Keisei's Edogawa Station toward the river, and you're up on the Edogawa riverbed. That's where the Koiwa Iris Garden is, with about 50,000 Japanese irises blooming from May to June.
The station's actual name is just Edogawa; the "Keisei" in the neighborhood name is something we added, to avoid confusion with Edogawa City. It's the last station within Tokyo on the Keisei Main Line before it enters Chiba, and from the platform you can see Konodai Station across the river.
This neighborhood covers most of Kita-Koiwa 1-chome, Kita-Koiwa 3 and 4-chome, and Higashi-Koiwa 3-chome, with a population of about 12,000 in 2020.
From our street photos, greenery ranks 251st out of 395 neighborhoods in Tokyo, in the middle of the pack, which is this neighborhood's highest-ranking category.
Public transit ranks 271st, toward the bottom: Edogawa Station is served only by Local trains, with Limited Express and Rapid trains passing through without stopping.
The street in front of the station is one-way, with no bus stop; the nearest bus service to Edogawa Station is the Keisei Bus Shinko 52 route, bound for Shin-Koiwa Station and Ichikawa Station.
This neighborhood is a low-density residential area, with about 90 people per hectare, and it also includes the Edogawa River's embankment and riverbank.
Sidewalks rank 385th out of 395 neighborhoods in Tokyo, and medical/pharmacy access ranks 379th, both toward the bottom.
Of the 49 street photo grid squares, 42 are in Kita-Koiwa 3 and 4-chome, with only 2 in Higashi-Koiwa 3-chome, so the score mainly reflects the former.
Based on the Geospatial Information Authority of Japan's flood inundation hazard maps, we took sample points roughly every 40 meters within the neighborhood: excluding the river surface, riverbed, and embankment, the residential area almost entirely falls within the projected flood zone, mostly at depths of 0.5 to 3 meters, with about 30% exceeding 3 meters.
Edogawa City anticipates that in a large-scale flood disaster, flooding would persist for 1 to 2 weeks or more, so its policy is that all residents should, in principle, evacuate outside the City in advance.
During the Edo period, the Edogawa river crossing here served as a checkpoint: the shogunate set up a guard post (bansho) in 1616, which was upgraded to a checkpoint (sekisho) during the Manji era, to monitor people and boats crossing the river. The checkpoint was abolished in 1869, while the ferry crossing continued operating until 1904.
In 1912, Keisei opened a station by the river, initially called Ichikawa Station, which was renamed Edogawa Station in 1914.
In April 2022, the project to grade-separate the railway from Keisei-Takasago Station to the area near Edogawa Station was placed on the Ministry of Land, Infrastructure, Transport and Tourism's list for new construction preparation, meaning the preparatory stage before construction begins. The railway will be elevated or placed underground, eliminating 13 railway crossings along the line.

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.
