Oimachi: lantern-lit eating alleys by the east exit, residential streets west of the line
The closest neighborhoods in the same city.
Coming out of the east exit of Oimachi Station, you'll find the arch of the Higashi-koji dining street right there. Pass through it and you're in a narrow alley barely wide enough for two people to pass each other, lined on both sides with small restaurants.
Along the alley are long-established small restaurants, Western-style diners, and ramen shops, and in recent years bars have also increased. This stretch of alleys is said to have its roots in the black markets of the postwar period, and when dusk falls, red lanterns light up everywhere.
Back at the station heading west, this side of the tracks is mostly Oi 1-chome through 4-chome. Aside from the buildings in front of the station and the shops along Ikegami-dori, the rest is residential. In 2020, six out of ten households in this neighborhood were single-person households, and people in their twenties and thirties made up about three out of ten, both slightly higher than Shinagawa City as a whole.
The area around the station is one of the top commercial districts in Shinagawa City, and Atre Oimachi is right inside the station. JR's TRACKS exit connects directly to OIMACHI TRACKS in Hiromachi 2-chome next to the station, which has 81 shops and a movie theater. For everyday convenience, this neighborhood ranks 97th out of 395 neighborhoods in Tokyo, and even higher for healthcare, ranking 42nd.
The JR Keihin-Tohoku Line, the Tokyu Oimachi Line, and the Rinkai Line all meet here. In front of the station there are also Tokyu buses running direct to Shibuya, as well as airport limousine buses to Haneda Airport.
In 2020, this neighborhood had about 219 people per hectare. Buildings and storefronts in front of the station are densely packed. Based on our street photos, cleanliness ranks 320th out of 395 neighborhoods, while greenery ranks only 326th.
The new Shinagawa City office building next to the station is scheduled for completion in June 2029, and the surrounding land readjustment project will continue until March 2034.
One theory holds that the place name Oi comes from an old well at Kofuku-ji temple called the Well of Oi. However, the Engishiki, compiled in the 10th century, already recorded the name Oi, so the dates don't match up, and the origin isn't certain.
In 1908 this area was reorganized into Oimachi, and the name stayed on as the station name. The station opened in 1914, the Tokyu Oimachi Line connected to it in 1927, and the Rinkai Line didn't arrive until 2002. In March 2026, JR East opened OIMACHI TRACKS next to the station, with a central plaza of about 4,600 square meters.
The new Shinagawa City office building next to TRACKS will have 14 floors above ground, replacing the old main office building built in 1968. In the event of a disaster, JR's Block A and the new office building together can accommodate about 3,250 commuters unable to get home. The land readjustment project also includes part of Oi 1-chome.

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.

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.
