Food Labeling Act in Japan

Overview

The Food Labeling Act in Japan is the basic law that governs food labeling. Its purpose is to help ensure the safety of food consumption and enable consumers to make appropriate food choices by providing necessary information through food labels.

Food labeling in Japan covers information such as product name, ingredients, additives, net content, date labeling, storage method, country of origin, allergens and nutrition information. These items must be shown appropriately according to the nature of the product and the applicable labeling rules.

The Food Labeling Act provides the legal framework, while the Japanese Food Labeling Standards set out the detailed practical rules on what must be shown, where it must be shown and how it must be displayed.

Scope of Food Labeling

The Food Labeling Act broadly applies to food labeling for products sold to general consumers in Japan. Processed foods, fresh foods and additives are subject to different labeling requirements depending on their category.

For processed foods, important practical label items include ingredients, additives, ingredient country of origin, net content, best-before date or use-by date, storage method, manufacturer or importer information and nutrition labeling.

Depending on the product, additional checks may be needed for allergen labeling, country of origin, genetically modified food labeling, foods with health-related claims and other product-specific requirements.

Practical Points for Imported Foods

For imported foods, information shown on overseas labels, invoices, product specifications or manufacturer documents cannot always be used directly for the Japanese market. If the product is sold in Japan, the label must be reviewed under Japanese food labeling rules.

Common problem areas include ingredient names, additive treatment, allergen information, country of origin, ingredient origin, date labeling, storage method and importer information. These issues often become visible only at the domestic sales stage if they are not checked before importation.

Even if customs clearance has been completed, a product with an incorrect or insufficient Japanese label may face sales suspension, label correction, retailer objections or recall risk. Therefore, Japanese label preparation should be handled from the import planning stage, not only after the goods arrive.

Relationship with the Food Labeling Standards

The Food Labeling Act is the basic law, but the Food Labeling Standards are the central practical rules used when preparing actual package labels. In practice, business operators must check both the legal framework and the detailed standards.

For example, when preparing a Japanese label, it is not enough to know that ingredients or allergens must be shown. The business operator must also check the required wording, display order, units, date format, character size, applicable exemptions and supporting documents under the Food Labeling Standards.

This distinction is important for overseas suppliers and export-side freight forwarders because Japanese importers may request detailed ingredient, additive, nutrition, manufacturing and origin information that is not normally required on the overseas label.

Relationship with Advertising and Sales Descriptions

The Food Labeling Act mainly concerns food labels on packages and containers. However, product pages, brochures, advertisements and sales materials may also create legal issues under other Japanese laws.

For example, expressions that make a product appear significantly better than it actually is, health claims without sufficient evidence, excessive functionality claims for health foods, or drug-like expressions may need to be reviewed under the Premiums and Representations Act, Health Promotion Act or PMD Act.

For imported foods, overseas marketing materials should not be translated automatically for the Japanese market. The Japanese label, e-commerce page, advertising copy, social media posts and in-store displays should be checked together for consistency.

Practical Checklist

When reviewing matters related to the Food Labeling Act, the first step is to classify the product as a processed food, fresh food, additive or food with health-related claims. After that, the applicable labeling obligations and the related Food Labeling Standards should be checked.

For imported foods, it is important to check not only customs-related documents but also the Japanese label, product page and advertising expressions before domestic sales begin. Labeling defects may lead to sales suspension, label correction, recall risk, administrative guidance or disputes with retailers.

In practice, the following points should be checked:

• whether the product is a processed food, fresh food, additive or food with health-related claims;
• which mandatory labeling items apply to the product;
• whether ingredients, additives, allergens, net content and date labeling are properly shown;
• whether country of origin and ingredient country of origin labeling are required;
• whether nutrition labeling is mandatory, voluntary or eligible for omission;
• whether storage method and importer information are properly shown;
• whether overseas labels and specifications contain enough information for the Japanese label;
• whether the detailed display method should be checked under the Food Labeling Standards;
• whether package labels, e-commerce pages, advertisements, social media posts and in-store displays are consistent;
• whether advertising expressions require review under the Premiums and Representations Act, Health Promotion Act or PMD Act.

Why This Matters for Overseas Suppliers and Export-Side Freight Forwarders

For overseas suppliers, exporters, customs brokers and export-side freight forwarders, Japanese food labeling may appear to be an issue handled only by the Japanese importer. In practice, however, the importer often cannot prepare a compliant Japanese label without detailed information from the overseas side.

The practical issue is not only whether the product has a label in the exporting country. Japan may require different ingredient names, additive classification, allergen checks, origin information, date labeling, nutrition labeling and importer details. Early document preparation helps prevent label corrections, sales delays, retailer objections, recall risk and repeated requests from Japanese business partners.
