Designated Investigation Agency | Pre-contract Investigation of Soil Contamination Risk | Geotech

To prevent defects liability troubles and court disputes after land transactions, we propose a buyer-led historical land investigation and sampling as a preventive measure before the contract.

This is a pre-contractual self-investigation solution designed to thoroughly protect the buyer's rights and assets from "hidden defects such as soil contamination," which is the most likely source of disputes in land sale contracts. If contamination is discovered after the transaction is completed, there is a high risk of escalating into a protracted legal battle over damages and contract termination, which can significantly impact a company's management. Our service conducts a "buyer-side historical investigation" during the due diligence period before contract signing to objectively verify the authenticity of the seller's information disclosure. Furthermore, if there are suspicions of contamination, we proceed to a "voluntary Phase 2 sampling investigation" that has legal evidentiary value, establishing solid numerical evidence based on official analysis. Based on this scientific data, we clearly define the burden-sharing of remediation costs and special clauses regarding defect liability within the sales contract, completely eliminating the development risk of the buyer incurring unexpected cleanup costs. This is a strategic solution to maximize the safety of land transactions from a legal and contractual perspective.

Designated Investigation Agency | Voluntary Soil Contamination Survey to Prevent Defects in Land Sales | Geotech

To eliminate liability for contractual nonconformity and defect risks after the sale of the land, a voluntary land history investigation is conducted before the sale to demonstrate safety, ensuring reliable soil contamination measures.

The "contractual non-conformity liability" and "sales defect risk" associated with land sales can lead to significant management troubles after the transfer. In particular, soil contamination is impossible to assess visually, so if harmful substances are detected from land sold unknowingly, there is a risk of being charged substantial purification costs or damages. This technical document explains the importance and specific process of "voluntary soil investigation," which is extremely effective for sellers to avoid these legal sales defect risks. First, by conducting a "voluntary historical investigation" that thoroughly examines past usage history, the risk of underground infiltration of specific harmful substances is visualized. Then, if necessary, accurate sampling and high-precision analysis are performed to establish objective evidence proving the safety of the land. Investigations by Geotech, a designated investigation agency by the Ministry of the Environment, enhance transaction transparency through reliable data and neutral reports, supporting smooth land transactions and complete dispute prevention after the sale. It is an essential measure to protect corporate value and peace of mind.

Designated Investigation Agency | Self-management of Potential Contamination Risks on Land Without Legal Obligations

In voluntary land transactions without legal investigation obligations, the potential contamination risks of the ground are visualized through reliable self-history and sampling analysis by designated investigation agencies.

Even in land transactions that do not meet the specific requirements set forth by the Soil Contamination Countermeasures Act and do not trigger statutory obligations such as investigation orders from authorities, the risk of harmful substances being present in the ground cannot be completely denied. If a company neglects to take measures on the grounds that there is no obligation, and contamination is revealed after the transfer, it may face severe disadvantages such as social penalties beyond the legal framework, enormous environmental liabilities, and long-term legal disputes. This service is a voluntary investigation solution designed to proactively maintain corporate compliance and social responsibility, free from legal constraints. Leveraging advanced expertise as a designated investigation agency, we voluntarily conduct everything from self-initiated historical land use investigation reports that objectively substantiate the land's usage history to precise sampling analyses that demonstrate the presence or absence of contamination. By ensuring reliable scientific data is available before the transaction, we can completely visualize and eliminate often-overlooked ground risks, strongly supporting advanced governance appeals to stakeholders and ensuring safe and secure real estate transactions.

Designated Investigation Agency | Avoiding Residential Land Risks in Important Matters Explanation Based on Past Land Use History

Avoid legal risks in re-explanation. Thoroughly examine past land category change histories and mixed-use land risks in advance, and ensure the cleanliness of the underground through sampling in residential land transactions.

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.

Soil contamination investigation in the case of land transactions for printing factories.

Know the risks of cleaning agents and plating solutions in printing factories in advance to facilitate land transactions.

In transactions and redevelopment of former printing factories and binding shops, early detection of invisible soil contamination risks is essential. The harmful substances handled on-site vary greatly depending on the printing method and process, such as organic chlorine solvents widely used for offset blanket cleaning, hexavalent chromium as gravure cylinder plating solution, cyanide for undercoating, and lead derived from letterpress type. In particular, the drainage routes of organic chlorine solvents that were consumed and disposed of in large quantities during daily roller cleaning and plate development, as well as the risk of penetration into the floor, are the most critical points to focus on. The advantage of conducting early investigations lies in scientifically identifying these specific contamination risks, which can completely eliminate future risks of land value decline, construction delays, and legal setbacks considered illegal dumping, thereby enabling safe and rational land asset management and redevelopment planning.

Construction Soil Acceptance Standards Compliance Law for Addressing Strict Additional Regulations in the Metropolitan Area

Law for Clearing Construction Soil Acceptance Standards in Response to Strict Additional Regulations in the Metropolitan Area

The disposal of construction soil in the metropolitan area (Tokyo, Chiba, Saitama, etc.) is subject to very strict local ordinances and additional regulations due to concerns about inflow from other prefectures and inadequate soil filling measures. This service provides a comprehensive pre-compliance analysis that fully covers the significantly different acceptance standards and sampling specifications for each region. For example, it selects the most suitable acceptance sites for each location, such as the "5-point mixing method" for every 5000m3 in Chiba Prefecture, and the "mixing prohibition and sea reclamation standards" for every 2500m3 at Tokyo Port. Based on Geotech's expertise, it accurately screens the analysis items specified by the ordinances (including more than 45 items such as dioxins, oil content, and fluorine), thereby reducing excessive investigation costs while fully complying with regulations.

Pre-contract investigations to prevent stagnation in investment and development. Supporting rapid decision-making with accurate soil contamination sampling and early assessment.

In the practice of land acquisition by real estate developers and institutional investors, early identification of soil contamination risks is a decisive factor that can determine the success or failure of investment decisions. This service is an ideal self-investigation solution prior to the sales contract, tailored for buyer-led due diligence (DD). Leveraging our expertise as a designated investigation agency, we meticulously analyze the historical operational records of the target site within a limited negotiation period. We swiftly conduct optimal soil contamination sampling based on the degree of risk, tailored to the local conditions, and make early determinations regarding the presence and extent of contamination. This completely prevents prolonged negotiations and transaction stagnation caused by uncertainties in the underground environment, enabling an overall acceleration of the process. Based on objective evidence, we can pre-calculate remediation costs and accurately reflect them in purchase price negotiations and warranty clauses in contracts, thereby avoiding legal disputes after handover and robustly supporting safe and profitable real estate investment and development businesses.

Designated Investigation Agency | Strongly Facilitating Land Sales through Early Detection of Soil Contamination

Proving asset value in advance through seller-led voluntary surveys. Early determination through accurate soil contamination sampling accelerates transaction speed.

In the sale of corporate assets and factory sites, the risk of underground soil contamination becomes the biggest barrier that can lead to the breakdown of negotiations or unjustified price reductions. This service is a proactive self-investigation solution conducted by the seller before the sales contract, allowing them to take the initiative. It involves a rigorous historical investigation and soil contamination sampling by a designated investigation agency, serving as a health check for the land, to determine the presence of contamination at an early stage. This enables reliable information disclosure to the buyer, alleviating concerns about environmental risks and dramatically accelerating the transaction speed. By preparing clear evidence in advance, the asset value of the land can be justifiably demonstrated, deterring excessive depreciation demands from potential buyers and facilitating agreement under favorable conditions. Even if contamination is confirmed, the company can calculate optimal countermeasures and costs under its own leadership before public disclosure, allowing for budget planning in line with management strategies and control over handover conditions, thus supporting strategic asset liquidity without stagnating real estate transactions.

Designated Investigation Agency | Avoiding the Risk of Stagnation in Real Estate Transactions through Early Detection of Soil Contamination

Voluntary investigation conducted at any timing before legal obligations. Early determination through accurate soil contamination sampling to accelerate transaction speed.

In real estate transactions, investigations conducted at the stage when statutory obligations arise under the Soil Contamination Countermeasures Act can cause the progress of the sale to be halted for an extended period due to reporting to authorities and the designation procedures for areas requiring measures. This service is a voluntary pre-sale investigation solution implemented at any stage before statutory obligations arise, aimed at completely avoiding such procedural delays. While applying the neutral and strict standards of designated investigation agencies, we conduct flexible investigation designs that match the speed of private transactions, enabling early determination of contamination through accurate soil contamination sampling. Since we can quantify the risks of the underground environment at a stage where there is no immediate reporting obligation to authorities, it allows companies to fully grasp the cost of countermeasures and negotiation strategies internally. This helps prevent unnecessary reputational damage and transaction cancellations, supporting the formation of rational and smooth agreements that both sellers and buyers can agree upon based on objective environmental evidence, thereby leading to faster transaction speeds.
