Descriptions are the notes of licensed real-estate appraisers (不動産鑑定士) who assess each survey point for Japan's official land-price surveys — the national Land Price Publication and the prefectural Land Price Survey — translated from Japanese. The price level is that point's official land value relative to the median of all survey points in Iruma City (= 100) — a relative index, not a price. Some blocks are represented by a single survey point, and commercial points can sit far above the all-use median. MLIT publishes individual sold records only to district (大字) level, so block-level sold prices are not available; appraisal values are not sale prices and are not shown. Chome without an official survey point are not listed.
