Suginami杉並区

People first. About 590,000 people live here — 8th largest of 48. Compared with the 48, what stands out is the low share of couple with children (18.3% vs a median of 24.1%) and the high share of one-person households (58.6% vs a median of 47.7%). The table adds the range across census tracts.

Next, what gets built. Residential-only zoning — the designation that keeps shops, offices and workshops from going up next door — covers 80% of the zoned land here, against a median of 39% across the 48. Homes are built in commercial and industrial-type zones too, so this is not a measure of how much housing there is — it says what can be built beside you.

A 70 m² home here, levelled to 20 years old and today's prices, costs ¥90M — high for the 48 (what actually sold: median 40 m², 22 years old). The same figure runs ¥71M–¥109M across towns, so one number cannot decide it — the next section has the town-by-town table.

What comes up for sale is 35% 2LDK+ and 48% studio/1K — the mix of homes traded, not of who lives here (the median 2LDK+ share across the 48 is 62%). Homes sold here have a median age of 22 years (median of the 48: 23 years).

Renting? The going rates are about ¥108K/mo for a studio/1K, ¥182K/mo for a 1LDK and ¥254K/mo for a 2LDK (2LDK is high for the 48) — model estimates of asking rents derived from the town's sale prices.

Price and the headline rate are medians levelled to 70 m², 20 years old and the latest quarter; size is the median of what actually sold — a different yardstick, so price ÷ size is not the rate.

Of the 35 towns with a median, the priciest — Nishiogikita — runs about ¥1.56M/m², roughly 1.5× the cheapest, Zenpukuji at ¥1.01M/m². A single ward-wide figure hides that.

“Sample” counts all resale trades in the town (every layout). The price column is the market price levelled to the latest quarter, 20 years old and 70 m². 1 more town had trades but fewer than four, so they have no median and do not appear here (36 towns had trades in total). A small number means the figure is a rough indication. On narrow screens the “Age” column is hidden.

36% of the ward's inhabited land sits inside an assumed river-flood area.

Storm surge is assessed separately, and no assumed storm-surge area reaches the ward.

The assumed depth over that land is 0.5–3m for 14% (a first floor) and under 0.5m for 22%.

These maps cover river flooding and storm surge. They do not cover inland flooding — when drains and sewers cannot keep up with intense rain. Water pooling in low spots and underground floors happens outside the assumed areas too.

Median elevation is 44.5m, and 10% of it is on a steep slope (5% grade or more) — mid-range for the 48.

Ground: 0% of that land falls in the two most liquefaction-prone of the five bands — more resistant than most of the 48, and a further 11% falls in the next band down ("somewhat prone"). Liquefaction damages roads and buried utilities more than it topples buildings, so the risk shows up as how long water, gas and sewerage take to come back.

This is the assumed maximum scale — how deep water could get. Always check the official hazard map for your exact address.

Residential street crime in the ward runs at 20 incidents per km² of land a year — 23rd lowest of 48. Across its neighbourhoods it runs 5–54 (middle 80%), a wider spread than the gap between municipalities.

Over 90% of this figure is bicycle theft (94% in Tokyo, 93% in the neighbouring prefectures); the rest is theft from vehicles. Snatching runs to about 420 cases a year in all of Tokyo. So it is closer to “how easily bikes get stolen here” than to violent crime.

Rates run higher around stations and busy streets, where many of the bikes belong to people passing through. It also varies between neighbourhoods inside one ward, so check the map at town level.

Shinjuku is the nearest hub: a median of 23 minutes door-to-door, ranging from 12 to 42 minutes depending on where in the ward you are. The nearest station is 447m away at the median (straight-line). The table below lists station-level prices, ordered by number of trades — top 8 of the 19 with data; the rest can be expanded below it.

Across all 48 municipalities, the median distance to shops, clinics, schools, nurseries and parks falls between roughly 1 and 8 minutes on foot (straight-line distance at 80 m/min). It barely varies between areas, so it is no way to choose one; within any single area it varies a lot, so check the specific address.

Prices first: over the past decade, town medians here rose +3.9% a year — slower side (computed for 33 of 35 towns). Past growth is no guarantee of future prices.

Redevelopment districts — where the city government intends to encourage redevelopment — number 3 here: 成田東四丁目地区, 荻窪駅北口, 新高円寺駅前.

Looking ahead, the typical block here is projected at +2.2% population by 2050 vs 2020 — roughly flat of the 48 (median across the ward's reference points, reading the 250m-grid projection; not a ward-total forecast).
