Protect the social credibility of the company. Rigorously examine past land category change histories and mixed-use land risks, and completely visualize potential underground contamination through residential land transaction sampling.

This technical document is a specialized resource for corporate CSR (Corporate Social Responsibility) departments, legal risk management personnel, and general affairs managers overseeing real estate assets. It rigorously evaluates environmental risks associated with land transactions and the operation of owned assets based on historical land registration categories, aiming to strengthen compliance. Even if the current status is generally residential land, tracing back the historical "land category change records" beyond forests and wilderness becomes a decisive defense measure to identify past facility usage that may have caused soil contamination. In particular, it details the rigorous historical verification process that identifies the duration of "mixed land risk," which is prone to the improper handling of hazardous substances and waste abandonment, by cross-referencing aerial photographs and public registries. Furthermore, it covers the procedures for "residential land transaction sampling" that substantiate safety with objective data, as well as reliable evidence acquisition methods by designated investigation agencies. This document effectively prevents the loss of social credibility and disputes over damages due to environmental contamination discovered after handover, strongly supporting sincere land transactions and the maintenance of corporate value.

Applications/Examples of results

This survey will be used for a comprehensive assessment of environmental risks associated with company-owned land as part of CSR activities, risk disclosure related to the sale of factory sites and company housing sites, and governance audits during new land acquisitions. Before contract signing, it is optimal for practices that identify potential risks of hazardous substances from past mixed-use land through land use change tracking and scientifically confirm the safety of the underground environment through sampling. This will be utilized to ensure compliance with laws and regulations, provide public proof of integrity to business partners, and mitigate risks to protect corporate value.
