Japanese Real Estate Due Diligence: Official Checks Before Purchase

更新日: 2026-09-02 / 最終確認日: 2026-09-02

Real estate due diligence should examine not only price but also title, legal restrictions, building condition, management, disaster exposure and the local market using multiple primary sources.

Core checks

  • Registered ownership and rights
  • Zoning and legal restrictions
  • Building condition, repairs and condominium management documents
  • Flood and other hazard information
  • Nearby transactions and official land values

The statutory important-matters explanation is essential, but it does not replace every investment check. Identify missing documents and unresolved issues before contract.

Verification date

Based on primary Japanese government sources checked as of September 2, 2026. Confirm current rules and property-specific documents for each transaction.
