Agricultural Chemicals Regulation Law (Law No. 82 of 1948).

The purpose of this Act is to ensure the safety and other qualities of agricultural chemicals, and their safe and proper use, by establishing a registration system of agricultural chemicals and regulating their sale and use, and thereby to contribute to the stability of agricultural production and the protection of the people's health and to contribute to the conservation of the people's living environment.
The term agricultural chemicals as used in this Act means bactericides, insecticides, herbicides and other chemicals to be used for controlling bacteria, nematodes, mites, insects, rats, weeds, or other animals or plants or viruses that harm crops, and growth stimulants, germination inhibitors and other chemicals (excluding the fertilizers provided in the Fertilizer Regulation Act (Act No. 127 of 1950)) that are used for enhancing or inhibiting the physiology of crops, etc. Manufacturers or importers must not manufacture, process or import agricultural chemicals unless those agricultural chemicals are registered by the Minister of Agriculture, Forestry and Fisheries. A person engaged in the business of manufacturing or processing agricultural chemicals in a foreign country which are exported to Japan, and selling them may have the relevant agricultural chemicals registered by the Minister of Agriculture, Forestry and Fisheries. In order to ensure the safe and proper use of agricultural chemicals, the Minister of Agriculture, Forestry and Fisheries, and the Minister of the Environment must establish the standards which users of agricultural chemicals must comply with.
Further the Law sets out rules for the registration such as its application, validity, succession, etc. In addition, the Law provides for the rules for the sales, advertisement, packing and labelling of agricultural chemicals, and the measures for inspection, offences and penalties.
