Japanese Agricultural Standards
From Wikipedia, the free encyclopedia
Japanese Agricultural Standards (日本農林規格 (Nihon Nōrin Kikaku?)) are industrial standards for the agriculture industry maintained by the Japanese Government. They are comparable to Japanese Industrial Standards but for food and agricultural products. Also included is the grading of lumber for import into Japan. JAS #1 lumber or often called J lumber is of the highest quality dimensional lumber, with very few knots or blemishes, very straight. Lumber that is rarely seen in our own domestic lumber yards or home buildings.
International organizations that can certify to these standards include the Organic Crop Improvement Association.
