Soil contamination investigation eliminates transaction risks through historical research.
Soil contamination survey, historical investigation
Eliminating transaction risks through due diligence investigations.
In the real estate appraisal standards, the presence or absence of soil contamination is clearly defined as an important individual factor in residential, commercial, and industrial areas, and it is one of the price formation factors that determine the utility and economic value of real estate. To make proper price assessments and judgments on the highest and best use, it is essential to clearly understand and analyze this risk from the perspective of market participants. Therefore, conducting a historical investigation (Phase 1) at an early stage before purchasing or transferring land is extremely beneficial in preventing unexpected declines in asset value and avoiding troubles during land transactions. Even if the land currently appears to have no issues, researching the history of past factories or similar establishments through residential maps or registries can help control the risks associated with the transfer in advance.

basic information
Our Phase 1 environmental site assessment will be provided as a designated investigation agency under the Soil Contamination Countermeasures Act, offering reliable technical specifications directly related to the foundational data for real estate appraisal and legal obligations. The assessment will comprehensively collect and organize objective information regarding the subject site, including residential maps, registries, and public documents, and will analyze the historical changes in land use from the past to the present to evaluate the potential for soil contamination. In particular, we can also handle cases where the development area exceeds 3,000 m², triggering legal investigation obligations. The reference price is set from 130,000 yen (depending on the size of the land), and we will prepare and deliver a survey report as documentation to understand and estimate the impact on objective price formation within the scope of our own investigation and analysis capabilities.

■ Specific Procedures 1. Confirmation and Consultation of Purpose and Conditions: We will confirm the scope of investigation and conditions according to the purpose of the request, such as land sales, handovers, and legal obligations for development areas exceeding 3,000m2, from the perspective of specialized technicians. 2. Collection and Organization of Materials (Planning according to Land Scale): To ensure a reliable understanding of the target real estate, we will systematically collect registration certificates (land registries), maps related to the location, and historical materials. 3. Investigation of Past Land Use History (Phase 1): Based on residential maps and registration information, we will thoroughly investigate the history of past factories and hazardous substance usage that may be hidden in land that currently appears to be problem-free, and assess the potential risks. 4. Analysis and Evaluation of Price Formation Factors (Individual Factors): Based on the collected historical data, we will analyze and examine from multiple perspectives the presence and condition of soil contamination risks as indicated by appraisal evaluation standards for residential, commercial, and industrial land. 5. Preparation of Investigation Report and Planning of Countermeasure Costs (Reference Price: 130,000 yen and up): We will create a report that logically organizes the analysis results and determines the possibility of soil contamination. If risks are identified, we will link this to budgeting for countermeasure costs in preparation for future sales.
