A dyeing town named alongside Kyoto and Kanazawa in the Showa era, where dyed cloth hangs over the river in February
The closest neighborhoods in the same city.
On the slope in Nakai, the slopes from Ichi-no-saka to Hachi-no-saka (Slope 1 through Slope 8) line up side by side; some are flanked by Oya stone walls and hedges, others curve left and right surrounded by bamboo groves. Kami-Ochiai, meanwhile, sits on the low ground along the Myoshoji River, with houses packed closely together; the lanes are full of greenery and have a strong sense of everyday life. From the early Showa era into the Showa 30s, more than 300 dyeing-related businesses gathered along the Kanda River and Myoshoji River basins, making the area one of Japan's three major dyeing centers alongside Kyoto and Kanazawa, and artisans and dyers who have inherited these techniques still gather in this area today.
In recent years, this history returns to the river's surface every February. Some no Komichi runs for three days, during which dyed cloth is hung across the Myoshoji River, and shops around Nakai Station also hang dyer-made noren curtains at their entrances. What it recreates is the sight, from before the Showa 30s, of dyed cloth being rinsed in the river.
On an ordinary day, Kami-Ochiai is mostly residential; its three chome are home to about 15,000 people, while only about 3,500 people work there. Along the old road Arai Yakushi-do, small shops line up to form a shopping street.
On the slope, the Hayashi Fumiko Memorial Hall sits right next to Yon-no-saka (Slope 4). This was the new home that Hayashi Fumiko, author of Horoki (Diary of a Vagabond), moved into in 1941; she lived there until she died in 1951, and the garden has wild mountain flowers blooming through all four seasons.
Nakai Station is served by the Seibu Shinjuku Line and the Oedo Line, and together with the Tozai Line at Ochiai Station, that makes three lines in total. For public transit, it ranks 87th among Tokyo's 395 neighborhoods, and for everyday convenience it ranks 90th. The Oedo Line runs directly to central Tokyo, so many nearby residents especially rely on Nakai Station.
Judging from our street photos, cleanliness ranks 357th among Tokyo's 395 neighborhoods, and sidewalks rank 367th — the two lowest-ranked items for this neighborhood. Kami-Ochiai's housing is dense, and with major roads running along its east and south sides, the tall buildings along those roads affect the look of the back lanes. Seibu's Nakai Station and the Oedo Line's Nakai Station are separated by the Myoshoji River with no passage connecting them, so transferring means exiting the station and walking a stretch first.
In 1927, Nakai Station on the Seibu Shinjuku Line opened. From the early Showa era onward, houses were gradually built on the slopes of Nakai, and the slope roads were cut through one by one as the residential land was developed.
In 1930, the year Horoki was published, Hayashi Fumiko moved to Ochiai, and it wasn't until 1939 that she bought this plot of land in Nakai. Nearly forty years after the Seibu Line opened, Ochiai Station on the Tozai Line finally opened in 1966, and in 1997 the Oedo Line also reached Nakai.

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.

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.
