01First impressions

Nikon built a factory in Nishi-Oi in 1918, the year after the company was founded, and it remained a production site for cameras until 1988. In July 2024, Nikon's head office also moved in; walking from the station along Kogaku-dori, you'll see it before long. The street's name comes from the company's former name, Nippon Kogaku Kogyo.

The building's double-height lobby connects to the Nikon Museum, which is open to the public too; the shiny fragments embedded in the floor are scrap from optical glass that failed quality inspection. Nishi-Oi Station is built directly beneath the elevated tracks of the Tokaido Shinkansen.

02What works

Some Shonan-Shinjuku Line trains stop here, running through to Shinjuku to the north. The station is also served by Yokosuka Line trains and through trains from Sagami Railway, and Shinagawa is the next stop on the Yokosuka Line. For transit, it ranks 129th out of 395 neighborhoods in Tokyo, around the middle.

There's the Core Stare Nishi-Oi shopping center in front of the station, and Nishi-Oi Plaza Park near the station as well. Outside the neighborhood, in Futaba 4-chome, there's Hebikubo Shrine, where a small shrine beside the main hall enshrines a white snake.

03Heads-up

Only JR lines run through the station; to take other lines you'll need to walk to Oimachi, Shimo-Shinmei, or Nakanobu, and just walking to Oimachi takes about 20 minutes. Based on our street photos, the neighborhood environment ranks 357th out of 395 neighborhoods, toward the lower end. Greenery ranks 363rd.

04A bit of history

Ito Hirobumi had a villa here in his later years, and after his death in 1909 he was buried on the site of the villa; the grave is in Nishi-Oi 6-chome and is now a historic site designated by Shinagawa City. In 1932, the area around 5- and 6-chome was still called Oi-Ito-cho; the name Nishi-Oi didn't come into use until the address reorganization of 1964.

The station's construction was disputed for years; a 1980 court ruling blocked Shinagawa City from spending public funds on it, and the station didn't open until 1986.

How are these measured?

Compared against the Tokyo neighborhoods in this guide; metrics without enough data are not ranked. Shopping counts convenience stores plus the nearer of a supermarket or a traditional market (public and private retail markets); night markets, vendor zones and shopping-street shops are not counted. Transit is rail-first with a lower weight for buses.

TidyMap rates the street environment and everyday convenience. It does not assess the home itself, safety, noise or actual living experience. About data limits
