From subjective assessment to reproducible numbers

Checking hazard maps one by one, and architect eyeballing — replaced by a single API call.

Single-property PML

Probable maximum loss as a % of replacement cost for a 475-year return-period quake (10% exceedance in 50 years). The metric J-REIT risk policies reference directly.

Continuous scores from measured intensity

J-SHIS 475-year instrumental intensity (surface amplification included), mapped through a continuous function anchored at official JMA class boundaries. A reference to public data — not an AI estimate.

Real polygon lookup

Point-in-polygon against MLIT max-scale flood depth ranks and landslide warning zones. Real data, not a formula stub.

Source & granularity, always visible

Every response carries its sources (J-SHIS, MLIT, PLATEAU) and score granularity (1 km mesh, 475-year return period, data versions). No black boxes.
