Japan startup uses satellite, AI to identify abandoned houses

Japanese companies are using satellite imagery and AI to identify abandoned houses for potential sale as the country faces a rise in vacant properties.

Where Inc., a startup based in Tokyo, offers an AI service that analyzes satellite photos to spot signs of aging roofs, such as rust and discoloration, marking houses likely left empty.

According to government data, about 9 million houses in Japan were abandoned in 2023.

Where Inc. has gained around 50 client companies since launching the service in 2024.

The AI draws on technology initially developed for lunar crater analysis by a group linked to the Japan Aerospace Exploration Agency.

The service can also help locate land suitable for parking lots and solar panel installations.

A house rental company in Gifu used Where Inc.’s platform to find and purchase a neglected two-story home for 1 yen after contacting its owner through public records.

🧠 Food for thought

Implications, context, and why it matters.

Ownership clarity blocks AI-found homes; inheritance registration gaps persist

  • Japan counts 9 million abandoned homes yet 3.8 million akiya (long-vacant houses) list owner or market status as “unknown” and 330,000 were for sale in 2023 1.
  • Heirs were not required to register inherited titles, which left records outdated and kept properties in the names of the deceased 2.
  • In 2014, 63% of municipalities had trouble identifying landowners, with 16% tied to unregistered inheritances where Japanese tax offices had not investigated heirs 2.
  • AI vacancy scans only help if legal changes turn owner-unknown lots into listings. Heir searches can be slow and costly, especially when people live overseas or cannot be reached 2.

Real estate sites pairing akiya search with renovation financing can serve foreign and domestic demand

  • Hospitality founders plus property technology (proptech) startups see demand for rental akiya from city residents moving to rural areas, while supply is thin and many homes need work 3.
  • Public programs include akiya banks (municipal marketplaces listing vacant homes) plus renovation subsidies and grants 4. They also offer tax incentives and startup visas (residency pathways for entrepreneurs) 4. Cities like Imabari invite founders to invest in local businesses 4.
  • A weak yen fueled a tourism surge with a record 3 million overseas visitors in March 2024, which lifted interest in traditional stays 1.
  • A cross-regional marketplace that pairs AI discovery with help for subsidies plus renovation financing can grow faster by focusing on high-vacancy prefectures 5. Examples include Wakayama, Tokushima, and Yamanashi 5.
