The SUUMO Japan Real Estate API provides structured, real-time access to rental and buy/sell listings, station data, commute-based discovery, and agency information from SUUMO, one of Japan’s largest property portals. Japanese property search depends heavily on railway access and commute time, and this API is built around those real-world requirements.
What You Can Access
Search rentals or sale listings (condos, houses, and land) with rich filters, or use the unified matching engine for cross-type search. Count-based endpoints return per-ward and per-station match counts for a prefecture, ideal for filter previews and market sizing. Retrieve full detail for rentals, buy/sell listings, and new-condo projects, or resolve any SUUMO URL into structured detail with /property-by-url and /parse-url.
Station and commute search is a core strength. Pull railway line and station master data for a prefecture, and use /commute-search to find stations reachable within a chosen travel time and transfer count, powering relocation and apartment-search tools. City, ward, address master, and postal-code lookups round out the geographic reference data, and /nearby-facilities returns POI points in a bounding box as GeoJSON.
Recommendation endpoints surface similar rentals and similar buy/used-house properties, /popularity returns inquiry counts, and /agency returns real estate company and shop profiles by company code.
