Field notes
The site says it derives neighborhood areas from e-Stat’s small-area boundary data for the 2020 census and processes public hazard data from national agencies and municipalities. Its stated policy is to label uninvestigated hazards as “not investigated” rather than leave them blank, and it disclaims use as a replacement for official maps or evacuation guidance.
