Food Labeling in Japan

When shopping for food, many people want to check the product labels before purchasing. Here we introduce information about labeling of food products containing processed ingredients and allergens.

Labeling on Processed Foods

Information shown on processed food products packaged in packs, cans or bags usually include the product name, ingredients, additives, included quantities, best-before date, storage method, the name of the manufacturer, and other information. In addition to these, some items are displayed that are particular to specific foods.

Food Labels (products produced in Japan)

  • The common name for the contained item.
  • Ingredients.
  • For clarity, additives may be shown separately from the ingredients in the ingredients section.
  • The amount of the contents is displayed, specified in grams, milliliters or the number of items.
  • The best-before date and storage method.
    1. The name and address of the person or corporation that produced the product. As a general rule, the name of the manufacturer is displayed, but the name of the seller may also be displayed if an agreement to do so has been made with the manufacturer.
    2. The alphabet letters or symbols listed in the beginning with “+” alongside the supplier’s name are known as the factory mark; this is registered with the Consumer Affairs Agency as a unique symbol representing the manufacturing site where the manufacturer actually produced the product.

Time Limit Labels

Expiration Date

This date indicates the time limit within which the quality of the contained item(s) will remain in good condition if unopened and stored according to the recommended storage method. This date is displayed on foods whose quality deteriorates quickly, such as boxed lunches and delicatessen dishes. Since the quality of these types of products deteriorates relatively rapidly, the possibility of damage to consumers’ health is increased if this time limit has passed.

Best-Before Date

This date indicates the time limit within which all the expected quality of the contained item(s) is deemed sufficiently likely to be preserved if unopened and stored according to the suggested storage method. This date is displayed on foods whose quality can be maintained for a relatively long period of time, such as canned food and snacks. Since the rate of deterioration in product quality is slow, the relevant product may not necessarily become unsafe to eat even if the best-before date has recently passed.

  • The expiration date and best-before date apply when products are unopened and stored according to the recommended storage method. Therefore, the quality of the contained item(s) may deteriorate even before the time limit has passed if already opened or if not stored in the way indicated.
