This technical document serves as practical guidance for real estate brokerage companies and licensed real estate agents leading land and housing transactions. It aims to identify legal risks associated with important matters explanations (known as "juusetsu") and contracts by examining past registration histories, ensuring the avoidance of disclosure obligation violations and post-transfer defect disputes. Even if the current status is a typical residential land, scrutinizing the past "land category change history" from closed registration records is a decisive risk management measure to discover contamination risks from specific harmful substances lurking underground and the presence of buried objects before transactions. In particular, it explains a rigorous method for verifying land history that objectively identifies actual usage by utilizing chronological aerial photographs and administrative ledgers, focusing on the historical "mixed-use land risk," which is prone to claims for damages due to disclosure omissions. Additionally, it covers procedures for utilizing "land sale sampling" to perfectly complement the descriptions in important matters explanations and accelerate buyer agreement, as well as methods for obtaining reliable public evidence from designated investigation agencies. This specialized document aims to protect the social credibility of brokerage companies and promise clean and safe land transactions.
