Japanese Real Estate Due Diligence: Price, Title, Management and Hazard Checks
Real-estate due diligence starts before the site visit
Due diligence is not limited to institutional buyers. Individuals and smaller investors can perform substantial desktop checks before signing. MLIT’s Real Estate Information Library combines transaction and closed-price information, official land values, hazard information, planning data and nearby facilities. A useful framework is to separate the review into seven areas: price, regulation, hazards, building condition, management, tenancy and title.
Separate value analysis from legal constraints
Compare price with nearby transactions and official land data. For land, review road access, zoning, building coverage and floor-area ratios, fire regulations and planned roads. Public map data has timing and scale limitations, so final legal conclusions should be confirmed against municipal, road and building records. The registry should be checked for ownership, mortgages, attachments and other rights, then compared with the sales materials.
Condominium management documents can determine value
For a unit, review the bylaws, owners’ meeting minutes, long-term repair plan, management and reserve fees, arrears and major-repair history. A low reserve contribution is not only a low monthly cost; it may indicate future increases or special assessments. For a tenanted property, review the lease, deposit, renewal terms, arrears and remittance history.
Evaluate hazards on a separate axis
Flood, landslide, storm-surge, inland flooding and earthquake risk should be assessed beyond a simple in-or-out map classification. Consider expected depth, evacuation, equipment location, insurability and future leasing or resale impact. Use the site visit to verify level differences, retaining walls, encroachments, noise, odors and nearby development. The purpose of due diligence is not to find faults; it is to convert unknown risk into price, contract terms and a clear investment decision.
