Market Intelligence Map
Most property mistakes are market mistakes: the right building in a shrinking town is still the wrong investment. The Market Intelligence Map lets you compare markets across Japan — every prefecture and municipality, colored by hard government data — so you can decide where to invest before deciding what to buy.
Open it from Market Intelligence Map in the main navigation.
Why Start with the Market
Japan's regions are on very different demographic and price trajectories. A property's long-term rental demand depends on how many households its area will have over your holding period — and its price justification depends on what buyers actually paid nearby, not on asking prices. The map puts those signals side by side for the whole country, quantified and comparable.
The Three Metrics
Use the metric selector to switch what the map colors show:
| Metric | Unit | What it tells you |
|---|---|---|
| Household CAGR 2025–2050 | % p.a. | Projected household growth or decline — the demand tailwind (or headwind) over a long holding period |
| Median Transaction Price / m² | ¥/m² | What buyers actually paid, from reported real transactions — an anchor for judging asking prices |
| Land Price Change YoY | % YoY | Direction and speed of official land values — market momentum |
Land Price Change is a diverging metric: the color scale is anchored at zero, so gaining and declining areas are visually distinct at a glance.
Reading the Map
The national view shows all 47 prefectures as a choropleth — darker means higher for the selected metric.
- The legend (bottom of the map) shows the active metric with its unit, plus minimum, median, and maximum value ticks so colors translate to numbers.
- Grey areas mean "No data" — no published figures for that area, not a zero.
- Data sources — expand the toggle in the legend for the official attributions.
- Map controls let you zoom in and out and reset the view at any time.
Hover any region for a quick reading; click it to select.
Drilling into Municipalities
Click a prefecture to drill into its municipalities — the same metrics, computed per city, town, and village. The breadcrumb (Japan › Prefecture) tracks where you are, and Back to prefectures returns to the national view.
When you select a region, the map keeps you oriented: the selection is highlighted and labeled on the map itself, centered in view, with surrounding regions dimmed.
The Region Panel
Selecting a region opens a details panel docked beside the map (it never covers the legend). The panel shows all metrics for the region:
- The metric currently displayed on the map carries an "On map" badge.
- Each value comes with context — whether it sits above, below, or about the prefecture median, so a number like ¥36,000/m² immediately means something.
- Yen values are shown whole; percentage changes are sign-colored so declines read as declines.
- Where the underlying sample is thin — common in small rural municipalities — you'll see a "Low sample · figures indicative" badge: treat those numbers as directional, not precise.
- Missing figures show "No data" rather than a misleading zero.
From Insight to Properties
Found a market you like? Click "View properties in {region}" in the panel to jump to your property list filtered to that area — connecting the market view directly to the properties you've imported there.
The reverse workflow works too: when a property's AI analysis mentions demographic or price context, the map is where you can see that context spatially and compare it against neighboring markets.
Where the Data Comes From
Every layer is built from official Japanese government data:
- Household projections — National Institute of Population and Social Security Research (IPSS) prefectural household projections through 2050
- Transaction prices — MLIT buyer-reported real estate transaction records
- Land prices — MLIT official land price survey points
- Administrative boundaries — MLIT National Land Numerical Information (国土数値情報)
Full attributions are available under the Data sources toggle in the map legend.
