1. Why Only Products With the Organic JAS Mark Can Be Called "Organic"
The Organic JAS mark is a symbol designed to represent the sun, clouds, and plants. It signifies food produced using the power of nature, based on the principle of not relying on chemical substances such as pesticides and chemical fertilizers. This mark can be applied not only to agricultural products but also to processed foods, animal feed, livestock products, and algae products [1]. Since April 2001, it has been illegal to put the Japanese word for "organic" (in kanji or katakana), or confusingly similar wording, on products that do not have this mark [1]. This rule exists to standardize the conditions for using the word "organic," preventing it from having vague or varying meanings depending on who uses it. So, who decides which products are allowed to carry the mark? Does the government visit every single field to check?
2. Who Sets the Organic Standards and Who Inspects Farms and Factories
The government is responsible for setting the standards and specifications. However, the actual work of certification—checking whether these standards are met—is carried out by third-party organizations registered by the government, known as registered certification bodies [2]. Separating the people who make the rules from those who check compliance is intended to help inspectors act fairly. These certification bodies do not just review applicants; they continue to check if certified producers meet the standards after certification is granted. If standards are not met, they can issue improvement notices, suspend operations, or revoke certification [2]. Each body is registered for specific geographic areas and types of agricultural and forestry products. Producers must apply to a body that covers their location and product type, and fees, services, and the scope of certification can vary between bodies [1]. But what exactly do these bodies check in the field?
3. What Inspectors Check in the Field: The Two-Year Rule for Fertilizers and Pesticides
For organic agricultural products, the standards generally require that chemical fertilizers and chemically synthesized pesticides have not been used for at least two years before sowing seeds or planting seedlings. For perennial crops, this period is at least three years before harvest [3]. The use of genetically modified seeds or seedlings is also prohibited. Additionally, producers must take measures to prevent prohibited materials from drifting or flowing in from neighboring fields [3]. Registered certification bodies verify that the fields and processing facilities meet these production standards and that proper production management records are being kept. These records allow inspectors to trace back "how many years" have passed, which cannot be seen just by looking at the field today [4]. However, this does not guarantee that no pesticide residue at all remains. It is a standard that defines a specific period and the methods used during that time. Once a producer is approved, who applies the mark, and how?
4. Why Certified Farmers and Factories Apply the Organic JAS Mark Themselves
The act of applying the mark is called "grading" and is performed by the certified producer themselves [2]. It is not the certification body staff who stick the labels on one by one; instead, the producer takes responsibility for applying them. To prevent misuse, the stickers or printed packaging for the mark are kept under the control of the person in charge of grading. The number of labels used is tracked in an inventory ledger. This is an example of management practices found in the organic feed handbook [2]. Verification continues even after products reach the store. Sampling inspections at markets, on-site investigations of business premises, and accepting reports from consumers are all part of ensuring proper labeling [5]. The government sets the standards, agencies inspect, producers apply the mark, and the market is also monitored. This system also applies to organic food coming from abroad.
5. How Japan Treats Organic Foods Imported From Other Countries
There are international guidelines for organic food worldwide. The Codex Alimentarius Commission adopted guidelines for the production, processing, labeling, and marketing of organic food in 1999 and revised them in 2001, 2003, 2004, and 2007. These guidelines describe organic agriculture as a "holistic production management system" that enhances biodiversity and soil activity [6]. They also state that genetically modified organisms and their derivatives do not align with the principles of organic production [6]. This aligns with Japan’s standard, which prohibits the use of genetically modified seeds and seedlings. When selling organic food from overseas in Japan, the labeling rules of the Organic JAS system still apply. The product must either be certified in Japan or come from a country or region whose certification system Japan has recognized as "equivalent." "Equivalence" is a system where countries agree to treat each other’s organic certification systems as equal to their own [7]. The scope of this "equivalence" varies by country and product type. For example, according to a document dated May 18, 2025, organic agricultural products, livestock products, and processed foods (including alcohol, but excluding processed algae products) that are produced and processed in Japan and graded can be exported to the EU, and organic agricultural products and other eligible products produced and processed in the EU and certified there can be imported to Japan. Conditions such as the issuance of certificates must also be met [8].
6. How to Investigate Organic JAS Marks on Food at Home
If you want to try investigating this yourself, there are simple steps you can take today. Look through the food items in your home and find those with the Organic JAS mark. Read the labels near the mark to see if the business operator’s name and the name of the registered certification body that certified the product are listed. When you go out, compare the same type of food in a store. Look at items with the Organic JAS mark and those without it to see how the labeling differs. For official information, the Ministry of Agriculture, Forestry and Fisheries has an "Organic JAS" page with explanations of the system and the latest updates.
