Landing page captured for the 2026-08-27 issue.

Field notes

The site compares stations rather than individual properties, grouping its analysis into six axes that range from flood, earthquake, and crime indicators to schools, medical access, land-price trends, and zoning. Results are calculated within an 800-metre radius, with point size representing walking-zone population. Coverage spans 1,924 stations across the Tokyo metropolitan region, and the source list includes national geospatial data, J-SHIS, e-Stat, and prefectural police statistics.
