The law concerning reporting, etc. of the release to the environment of specific chemical substances and promoting improvement in their management ("Law for PRTR and Promotion of Chemical Management" or "PRTR Law") was enacted in 1999. The purpose of this law is to promote businesses' voluntary improvements in the management of specified chemical substances and to prevent any environmental protection impediments. This law requires businesses to report the release and transfer of chemical substances of concern(PRTR reporting) under the PRTR System and to provide information on them under the SDS System.

Only businesses in the published types of industries are obliged to confirm and notify the release amounts of chemical substances in the environment.
