Japan First: Free Condo Price Index Built on AI Appraisals of 146,000 BuildingsA · FULL TRANSLATION
- Fintech-proptech firm MFS released the CAPS Index free to the public
- Billed as Japan's first condo price index built on AI appraisals of 146,000 buildings
- The index runs on the engine behind CAPS, the AI valuation service launched July 13
- High-frequency pricing data narrows the information gap official statistics leave
With asking and contracted prices decoupling across Japan's used condo market, this tool arrives on cue. MFS, which began as a mortgage comparison platform, has converted the engine of its July 13 AI valuation service CAPS into a public index: AI appraisals across 146,000 buildings nationwide, aggregated and published free as the CAPS Index—billed as Japan's first.
Its value shows against existing gaps: official property indices lag months, REINS transaction data serves only licensed agents, and ordinary buyers navigate in fog. A reliable high-frequency index hands retail buyers a thermometer—how far does this asking price stray from market—quantified free for the first time. Caveats apply: AI appraisal error widens where transactions thin out, so treat it as a compass rather than a precision instrument. It also illustrates the PropTech playbook: free valuation data as the traffic funnel, monetized through mortgage and brokerage referrals. Details per the company release.
MFS Inc. (headquartered in Chiyoda-ku, Tokyo; CEO Akira Nakayamada), a fintech and proptech company, announced the free public release of the CAPS Index, a condominium price index built by indexing AI appraisal results across 146,000 buildings nationwide, powered by the valuation engine of CAPS, its real estate AI appraisal service launched on July 13. The company bills it as the first index of its kind in Japan.
The index presents condominium price trends through aggregated AI valuations, aiming to fill the information gap left by lagging official statistics and industry-only transaction data, making market pricing more accessible to ordinary consumers.
