Urbalytics

Urbalytics is aimed at people who make money decisions about Japanese property: individual investors, brokers and owners. Its central premise is that the visible asking price hides most of what matters, so the platform assembles and visualizes the record behind a listing — every price revision, relisting, withdrawn listing and recorded sale, plus how the current price sits against comparable deals nearby. The site reports roughly 5.77 million tracked properties and over 19.8 million sale and price-history records, and it currently covers the four prefectures of the greater Tokyo area.

Functionally the product splits into free and paid layers. Free includes sale-history search, an undervaluation checker that scores a property against past transactions for its area and type, a self-service price estimate that accepts a listing URL, manual entry or photos and requires no sales follow-up, a 30-year cash flow and IRR simulation, an investment map of average yields by area, and favourite-property watching with alerts for price changes and relistings. The paid Plus tier adds neighbouring sale history, price-change and completed-deal records, market rent versus actual rent upside analysis, rental appraisal and undervaluation amounts.

An unusual feature of the platform is its editorial layer. Urbalytics publishes market reports broken down by developer brand, municipality, station and postcode, plus a 'price cut watch' section that aggregates the median reduction for apartments, single buildings, houses and land, alongside a blog with market analysis. The company is explicit that it is not an investment advisory or financial instrument sales service — the information is presented as reference material for the user's own judgement.
