Property Price Mirror

Learn the real market price of Japanese property from actual transaction data. Advertised prices are ASKING prices — they differ from the price a property actually sold at. This app taps into the Real Estate Information Library published by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) to show area market prices and a reference valuation of your property, based on real transaction records. ■ Area Market (free) - Pick an area by address, postal code, or a tap on the map - Transaction median, price range, and distribution (histogram) - Toggle between per-square-meter, per-Tsubo, and total price - Quarterly market trend chart - Counts and unit prices by decade of build and by area band - List of recent transactions - Zoning (building coverage, floor area ratio) - Hazard info (flood, landslide, tsunami, storm surge, liquefaction) - Divergence between published land prices and actual transactions - Area Market PDF export - Search history (revisit without re-fetching) ■ Property Valuation (one-time purchase) Enter address and area, and we compute a reference valuation of your property from nearby transactions. - Time-of-sale adjustment, building-age standardization, frontage / road-width / land-shape corrections - AI commentary that explains the reasoning in plain language - Valuation report PDF (useful for family discussion or broker negotiation) - Estimates for property tax and city planning tax - Valuation history saving ■ Zero sales calls Unlike bulk-valuation-request services offered by real estate companies, this app does NOT require your name or phone number. Check the market yourself without handing personal info to brokers. ■ Before you use this app The valuation is a reference market price based on the "sales comparison approach" of Japan's real estate appraisal standards. It is NOT a formal appraisal by a licensed real estate appraiser. Transaction data reflects past records and does not guarantee actual sale prices. Individual factors such as sunlight, view, and interior condition are not reflected. For formal price decisions or a decision to sell, please consult a real estate agent or licensed appraiser.
