01First impressions

Between Ohanajaya and Shiratori, there used to flow the Hikifune, a canal dug during the Edo period. After the sewer system was completed in 1989, the waterway was filled in and turned into Hikifune-dori and a waterside park along the old riverbed. The park stretches about 3 km from Kameari to Yotsugi, with a water play area, a watercourse, and lawns, about an 8-minute walk from Ohanajaya Station.

Shiratori, on the east side of the park, is mostly residential; Shiratori 3-chome also has the City's local history and astronomy museum, which holds stargazing events every Friday and Saturday.

As of 2020, this neighborhood had a population of about 39,000, or about 172 people per hectare.

02What works

Healthcare (medical and pharmacy) ranks 109th out of 395 neighborhoods in Tokyo, near the top, the strongest category for this neighborhood. Daily shopping ranks 115th, also near the top, with three supermarkets right around the station.

Ohanajaya Station is served only by Local trains, with no transfer needed to Nippori or Keisei Ueno; there are also buses from the station to Kameari Station and Ayase Station.

03Heads-up

From our street photos, street cleanliness ranks 374th out of 395 neighborhoods in Tokyo, the weakest category for this neighborhood.

These scores mainly reflect Takaramachi, Shiratori, and Ohanajaya 1- and 2-chome. In the northern half of the neighborhood, Ohanajaya 3-chome, Higashihorikiri 2- and 3-chome, and Nishi-Kameari 1-chome have no street photos available to score.

Public transit ranks 234th, in the middle. Nishi-Kameari 1-chome, at the northern end, is far from any station; the nearest stations listed for a few apartment buildings there are a 14- to 17-minute walk.

Based on the largest-scale flood hazard map from the Geospatial Information Authority of Japan, we sampled points roughly every 40 meters across the neighborhood and calculated them ourselves; every point falls within the area expected to flood, and all are expected to flood 3 meters or more.

In the event of storm surge from a major typhoon, or simultaneous flooding of the Arakawa and Edogawa rivers, the City office's policy is to evacuate in advance to higher ground outside the City that will not flood.

04A bit of history

The station's name comes from a legend: the eighth shogun, Tokugawa Yoshimune, got a stomachache while hawking in this area, and a girl named Ohana from a teahouse nursed him back to health, so the place name stuck.

Takaramachi, south of the station, took its name in 1961 from one character of its old name, Hokizuka, and is also the birthplace of the toy company Takara.

During the period of rapid economic growth, the Hikifune was polluted by household wastewater and wastewater from a nearby plating factory, giving off a foul smell. After the sewer system was completed and the waterway filled in, the waterside park opened in 1990.

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
