Adachi足立区

People first. About 700,000 people live here — 5th largest of 48. On all five measures below, the mix of residents here sits close to the median of the 48. 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 34% 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. Industrial-type zoning covers 27%, including zones where factories and warehouses can stand beside homes — how quiet a street is varies block by block.

A typical resale trade (2LDK+) here is 60m² at ¥33M — affordable side. The same figure runs ¥18M–¥69M across towns, so one number cannot decide it — the next section has the town-by-town table.

What comes up for sale is 62% 2LDK+ and 27% studio/1K — the mix of homes traded, not of who lives here (the median 2LDK+ share across the 48 is 63%). Homes sold here have a median age of 23 years (median of the 48: 24 years).

Renting? The going rates are about ¥85K/mo for a studio/1K, ¥134K/mo for a 1LDK and ¥179K/mo for a 2LDK (2LDK is mid-range) — model estimates of asking rents derived from the town's sale prices.

Size, price and the headline rate are each their own median — taken across different trades, so the division will not match exactly. 2LDK+ has fewer than four trades in 6 of 52 towns, so the median of all layouts stands in there.

Of the 52 towns with a median, the priciest — Hinodechō — runs about ¥1.30M/m², roughly 4.3× the cheapest, Hanahata at ¥300K/m². A single ward-wide figure hides that.

“Sample” counts all resale trades in the town (every layout). The price column is the median of 2LDK+ trades, but in 6 towns with fewer than four such trades we fall back to the median of all layouts. 15 more towns had trades but fewer than four, so they have no median and do not appear here (67 towns had trades in total). A small number means the figure is a rough indication. On narrow screens the “Age” column is hidden.

93% of the ward's inhabited land sits inside an assumed river-flood area.

Storm surge is a separate assessment: 42% of that same land sits inside an assumed storm-surge area. River flooding and storm surge are different hazards with different maps, so check both for a specific address.

Taking flood and storm surge together, the assumed depth over that land is 3m or more for 52% (deep enough to reach a second floor), 0.5–3m for 40% (a first floor), and under 0.5m for 1%.

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 2.0m, and 5.6% of it is on a steep slope (5% grade or more) — flatter than most of the 48. 10% of it sits below sea level. It is protected by levees and pumping, but it cannot drain by gravity, so water stays longer once it gets in.

Ground: 76% of that land falls in the two most liquefaction-prone of the five bands — more susceptible than most of the 48, and a further 24% 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 22 incidents per km² of land a year — 26th lowest of 48. Across its neighbourhoods it runs 0–55 (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.

Tokyo is the nearest hub: a median of 36 minutes door-to-door, ranging from 20 to 56 minutes depending on where in the ward you are. The nearest station is 630m away at the median (straight-line). 9 of the 108 survey points have no station within 1.5km and are excluded from the median and the range above. The table below lists station-level prices, ordered by number of trades — top 8 of the 22 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 +5.2% a year — high for the 48 (computed for 46 of 52 towns). Past growth is no guarantee of future prices.

Redevelopment districts — where the city government intends to encourage redevelopment — number 6 here: 千住大川端地区, 北千住駅西口, 竹ノ塚駅西口南, 綾瀬一丁目 and 2 more.

Looking ahead, the typical block here is projected at +2.1% population by 2050 vs 2020 — roughly flat of the 48 (median across the ward's survey points, reading the 250m-grid projection; not a ward-total forecast).
