A reclaimed artificial island, where large apartment blocks rose beside a station that wasn't in the original plan
The closest neighborhoods in the same city.
The entire town of Shiomi is a man-made island created by landfill. Shiomi Station on the JR Keiyo Line opened in 1990; when this rail line was originally planned, this station wasn't actually part of it. Large apartment buildings were later built around the station.
The island has Shiomi Sports Park and the SENKO Shiomi Tennis Court, and for everyday shopping there's the Maruetsu Shiomi store. Shiomi's population grew from 931 in 1995 to 6,097 in 2020.
This neighborhood covers Shiomi 1-chome and 2-chome, plus Edagawa 3-chome at the southern end, with about 137 people per hectare.
Commuting relies on the Keiyo Line: Shiomi Station is an elevated station; Rapid trains don't stop there, but trains that run through to the Musashino Line do stop. For public transit, it ranks 176th out of 395 neighborhoods in Tokyo, in the middle.
Based on our street photos, sidewalks rank 75th and buildings rank 50th, both near the top. For schools, both Shiomi 1-chome and Edagawa 3-chome are in the school zone for Edagawa Elementary School and Fukagawa Daihachi Junior High School.
The bus stop in front of Shiomi Station has very few departures, so when the Keiyo Line is suspended, you often have to walk about 10 minutes to a different stop. For healthcare, it ranks 319th out of 395 neighborhoods in Tokyo, toward the bottom.
The street photo grid used for scoring has 32 squares in total, but Edagawa 3-chome only has 5, so the score mainly reflects Shiomi 1-chome and 2-chome.
Based on the Geospatial Information Authority of Japan's flood inundation hazard map (maximum assumed scale), TidyMap sampled points roughly every 40 meters within the neighborhood and calculated the figures itself; about 55% fall within the flood hazard area, mostly under 0.5 meters, followed by 0.5 to 3 meters. Nearly 90% of Edagawa 3-chome falls within the hazard area. For your own address, please check Koto City's flood and storm surge hazard map.
From the late Meiji era, Tokyo used soil and sand dredged from rivers within the city to create landfill; Landfill Site No. 8, where construction began in 1924, roughly corresponds to what is now the Shiomi 2-chome area. Before this land was completed, it had long served as a disposal site for Tokyo's waste, and the landfill was completed in 1967. When it was incorporated into Koto City the following year, it was named Shiomi because the land carried the scent of the sea tide.
Subway Line No. 8 (the Yurakucho Line) is planned to extend from Toyosu to Sumiyoshi, with a (tentatively named) Edagawa Station in between, targeting opening in the mid-2030s. In March 2025, Koto City established neighborhood development guidelines for the area around the (tentatively named) Edagawa Station; a council made up of residents had previously submitted a proposal.
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.
