FAQs
If a soil survey based on laws and regulations is required, please ask a designated research organization (outside site). The designated research organization first determines the risk of contamination by investigating the land history, and, if necessary, conducts soil gas surveys and soil collection surveys. After that, land owners should submit a soil contamination status survey report to Yokohama City.
The soil contamination status survey report must be submitted in the name of the landowner, but since there is no provision for the cost burden, it can be freely determined with the lessee.
If soil contamination is confirmed as a result of a survey based on laws and regulations, it will be designated as an area, but there is no restriction on buying and selling land.
