Nutrition Labeling — Japanese Food Labeling Standards and Imported Food Practice
Interlink編集部What is Nutrition Labeling
Nutrition labeling is a system that displays the amount of nutritional components and calories contained in food on containers, packaging, etc. It allows consumers to check the nutritional content when selecting food products.
Under the Food Labeling Standards, nutrition labeling is mandatory for packaged general processed foods and general additives sold to consumers. When selling imported foods domestically in Japan, confirmation in accordance with Japanese labeling rules is also required.
Nutrition labeling basically includes calories, protein, fat, carbohydrates, and salt equivalent. Depending on the product, sugar, dietary fiber, vitamins, minerals, and other components may also be displayed additionally.
This article organizes the scope of foods subject to nutrition labeling, labeling obligations, cases where omission is allowed, labeling items, considerations for imported foods, nutrition claims, and the relationship with advertising and sales labeling, from the perspective of food labeling and import practice.

Purpose and Background of the System
Nutrition labeling is a system intended to allow consumers to check calories and amounts of nutritional components when choosing foods. It plays a role in enabling comparisons of products not only by taste, price, and place of origin but also from a nutritional perspective.
The food labeling system requires certain nutrition labeling for packaged general processed foods and general additives sold to consumers. As a result, consumers can check calories, protein, fat, carbohydrates, and salt equivalent as basic information.
For imported foods, even if the overseas label includes Nutrition Facts or a nutritional table, it does not necessarily mean it can be used as it is for Japanese labeling. Confirmation is needed to match the Japanese Food Labeling Standards for ingredient names, labeling order, units, conversion, rounding, and labeling units.
Situations Where Nutrition Labeling Applies
| Situation | Items to Check | Common Issues | Practical Notes |
|---|---|---|---|
| Selling general processed foods | Packaged processed foods | Whether nutrition labeling is mandatory | Check sales form and food category. |
| Selling general additives | Additives sold to consumers | Whether nutrition labeling is required | Check if they are for general or business use. |
| Selling imported foods in Japan | Overseas label, ingredient table, specifications, Japanese label draft | Mismatch between overseas labeling and Japanese labeling units or ingredient names | Reorganize for labeling intended for Japan. |
| Selling fresh foods | Agricultural, livestock, fishery products, etc. | Judgment of mandatory or voluntary labeling | Even for voluntary labeling, compliance with standards is necessary. |
| Handling business-use foods | Business-use raw materials and processed foods | Difference in treatment from consumer sales items | Confirm whether final sales form is for general consumers. |
| Making nutrition claims | Labels such as low calorie, reduced sugar, reduced salt, high protein, etc. | Claiming without meeting standard values | Confirm standard values and supporting documents before labeling. |
| Making nutrition claims on e-commerce pages or advertisements | Product pages, landing pages, SNS, advertisements, in-store POP | Claims of health effects beyond the label display | Check not only Food Labeling Standards but also the Act against Unjustifiable Premiums and Misleading Representations, Health Promotion Act, and Pharmaceutical Affairs Law. |
Application Requirements and Items Often Excluded
| Category | Content | Points to Confirm | Precautions |
|---|---|---|---|
| Items likely to require mandatory labeling | General processed foods and general additives in container packaging sold to consumers. | Confirm whether the item is general use, processed food, additive, and if it is in container packaging. | Even for imported foods, confirmation is necessary if sold domestically in Japan. |
| Items likely to have voluntary labeling | Fresh foods, commercial-use foods, etc. Labeling may be voluntary depending on product category. | Confirm food category, buyer, purpose, and final sales form. | If nutritional components are labeled voluntarily, the labeling must comply with standards. |
| Cases where labeling can be omitted | Foods sold by small-scale businesses and similar cases where omission is permitted under certain conditions. | Confirm seller, manufacturer, business scale, and sales form. | Whether omission is allowed should be checked according to individual conditions. |
| Imported foods with overseas labeling | Foods that have Nutrition Facts on their overseas label. | Check labeling units, ingredient names, Sodium, Serving size, and rounding methods. | Simply translating overseas labeling into Japanese is insufficient. |
| Foods with nutrition claims | Foods labeled as low-carb, reduced salt, high protein, calcium-fortified, etc. | Confirm standard values, comparative targets, reduction rates, content amounts, and supporting documents. | Separate confirmation of standards is needed for emphasized nutrition labeling apart from regular nutrition facts. |
| Foods promoting nutrition only through advertising | When nutrition or health benefits are promoted on e-commerce pages or SNS without labeling on the package. | Check advertising text, in-image wording, supporting documents, and the impression received by consumers. | Advertising labeling may still fall under the Act against Unjustifiable Premiums and Misleading Representations or the Health Promotion Act. |
| Items difficult to exclude from labeling requirements immediately | Samples, trial products, commercial-use, internal use by importers, event sales items, etc. | Confirm who receives the product, in what form, and for what purpose. | Labeling requirements may vary depending on actual sales conditions. |
Main Labeling Items
In nutrition labeling, energy, protein, fat, carbohydrates, and salt equivalent are the basic labeling items. Depending on the product, sugar, dietary fiber, vitamins, minerals, and other components may be additionally displayed.
The values displayed are set based on analytical data, calculated values, reference values, etc. For imported foods, it is necessary to check the composition tables and specifications obtained from overseas manufacturers and organize them into a form suitable for Japanese labeling.
| Labeling Item | Meaning | Documents to Confirm for Imported Foods | Practical Points |
|---|---|---|---|
| Energy | The amount of energy obtained from the food. | Composition tables, analysis certificates, manufacturer specifications | Confirm the labeling units and calculation basis. |
| Protein | One of the main nutritional components. | Analytical values, specifications, Nutrition Facts | Check overseas labeling and Japanese labeling units. |
| Fat | The amount of fat contained in the food. | Composition tables, analysis certificates | If emphasizing this component in labeling, standard values should be confirmed. |
| Carbohydrates | A nutritional component category including sugars and dietary fiber. | Composition tables, calculation basis, analysis data | If sugars and dietary fiber are labeled separately, confirm consistency. |
| Salt Equivalent | Salt equivalent value calculated from sodium content. | Sodium labeling, analytical values, conversion calculation data | Do not use overseas Sodium values as-is; convert to salt equivalent. |
| Voluntary Labeling Components | Sugars, dietary fiber, vitamins, minerals, etc. | Analysis certificates, specifications, supporting documents for emphasis labeling | Even for voluntary labeling, confirm according to applicable standards. |
Comparison Table: Mandatory Labeling, Voluntary Labeling, and Possible Omission
| Category | Main Targets | Judgment Criteria | Practical Precautions |
|---|---|---|---|
| Mandatory Labeling | General processed foods and general additives in container packaging for consumer use. | Confirm whether sold to general consumers, if the product is processed food/additive, and if it is container-packaged. | Confirmation is necessary even for imported foods sold to consumers within Japan. |
| Voluntary Labeling | Fresh foods, commercial-use foods, etc., may be voluntary depending on category. | Check food category, purpose, buyer, and final sales form. | Even when voluntarily labeled, labeling methods must comply with standards. |
| Possible Omission | Foods sold by small businesses fitting certain conditions. | Confirm business scale, sales form, target foods, and applicable conditions. | Avoid easy assumptions; check conditions precisely for omission eligibility. |
| When Emphasized Labeling is Performed | Foods labeled as low-calorie, low-carb, reduced salt, high protein, etc. | Confirm standard values, content amounts, comparison targets, and basis for labeling. | Separate verification of emphasized labeling standards is required apart from mandatory or voluntary labeling. |
Comparison with Other Systems
| System | Main Purpose | Main Items to Check | Difference from Nutrition Facts Labeling | Practical Points of Caution |
|---|---|---|---|---|
| Nutrition Facts Labeling | Clearly shows calories and nutrient amounts of food to consumers. | Calories, protein, fat, carbohydrates, salt equivalent, etc. | Check the amount of nutrients and labeling format. | For imported foods, adjust overseas labeling to Japanese standards. |
| Food Labeling Act / Food Labeling Standards | A system that sets the basic rules for overall food labeling. | Name, ingredients, additives, allergens, expiration dates, storage methods, nutrition facts labeling, etc. | Nutrition facts labeling is one area within the Food Labeling Standards. | Confirm overall consistency of the entire label. |
| Nutrition Claim Labeling | A system for labeling when nutrients are indicated as high, low, none, or reduced. | Expressions such as low sugar, reduced salt, high protein, calcium-fortified, etc. | In addition to standard nutrition facts labeling, compliance with criteria values is required. | Check criteria for each type of claim expression. |
| Act against Unjustifiable Premiums and Misleading Representations | A system to prevent misleading representations that cause consumer misunderstanding. | Advertising, sales pages, price displays, comparative claims, quality claims, etc. | Confirm not only numerical values but also overall impression perceived by consumers. | Check that nutrition and health-related expressions do not create an exaggerated impression. |
| Health Promotion Act | A system to prevent false or exaggerated claims regarding health maintenance and improvement effects. | Health foods, supplements, advertisements claiming health effects, etc. | The issue focuses on how health effects are promoted rather than nutrient amounts. | Pay attention to expressions such as "improve," "prevent," or "become healthy." |
| Pharmaceutical and Medical Device Act | A system regulating quality, efficacy, and safety of pharmaceuticals, quasi-drugs, cosmetics, and medical devices. | Efficacy claims, disease prevention/treatment expressions, advertisements indicating bodily effects, etc. | Becomes an issue when foods claim pharmaceutical efficacy. | Confirm that claims do not go beyond nutritional labeling to efficacy or therapeutic effects. |
Points of Caution in Imported Food Operations
For imported foods, even if nutrition facts are shown on overseas labels, these cannot always be used directly as Japanese nutrition facts labeling. Unit of measure, nutrient names, rounding methods, conversion to salt equivalent, and other aspects need to be checked to comply with Japanese standards.
In particular, when “Sodium” is stated in overseas labeling, it should be converted and displayed as salt equivalent in Japan, so this conversion needs to be confirmed. Also, discrepancies between serving size labeling common overseas and Japanese labeling units may exist.
Even when the nutrition facts from overseas manufacturers are used, the Japanese label should be verified to ensure that the food unit, display order, nutrient names, units, and rounding methods conform to Japanese Food Labeling Standards.
Relationship with Nutrition Claim Labeling
When making nutrient-related claims such as “low calorie,” “low sugar,” “reduced salt,” “high protein,” or “calcium-fortified,” it is necessary not only to display the nutrients but also to verify that the claim meets the criteria set by the Food Labeling Standards.
Nutrition claims include expressions indicating high content, low content, absence, or reduction. The applicable criteria vary by expression, so it is necessary to check the relevant tables or related notifications in the Food Labeling Standards.
Advertising claims related to nutrients may also fall under the Act against Unjustifiable Premiums and Misleading Representations as well as the Health Promotion Act regarding misleading claims. Special caution is required for expressions that strongly imply health benefits.
Relationship with Advertising and Sales Displays
Nutrition facts labeling applies not only to container or package labels but also extends to sales pages, advertisements, social media, and in-store POP displays.
For example, even if the label contains only standard nutrition facts, if EC pages or advertisements include expressions like “ideal for maintaining health” or “improvement by just drinking daily,” issues under the Act against Unjustifiable Premiums and Misleading Representations, Health Promotion Act, or Pharmaceutical and Medical Device Act may arise.
In the case of imported foods, directly translating overseas sales materials or advertising text could be considered excessive health claims in Japan. It is important to separately verify label content and advertising expressions for sales in Japan.
Application Flow of the System
- Confirm whether the product falls under food, additives, fresh food, processed food, or commercial-use food.
- Confirm whether it is a general-use processed food or general-use additive sold to consumers in packaged form.
- Check if nutrition facts labeling is mandatory, voluntary, or can be omitted.
- Confirm that required items—calories, protein, fat, carbohydrates, salt equivalent—are all displayed.
- Confirm that display units, order, nutrient names, units, and rounding comply with Japanese Food Labeling Standards.
- For imported foods, convert and organize overseas labeling Sodium, Serving Size, Nutrition Facts to Japanese labeling.
- Confirm if source documents such as composition tables, product specifications, or lab certificates supporting the numeric values exist.
- Confirm whether any nutrition claim labeling such as low calorie, low sugar, reduced salt, or high protein is used.
- Check that nutrition and health claims on advertising, EC pages, social media, or in-store POP are not excessively promoted.
- If issues are found, take corrective action before sales start, including label revision, obtaining evidence documentation, and expert verification.
Common Practical Problem Cases
| Case | Issues | Points to Confirm | Practical Response |
|---|---|---|---|
| Directly translating overseas Nutrition Facts labels | Display units, order, ingredient names, and rounding may not align with Japanese standards. | Overseas label, Japanese label draft, display units, display order, ingredient names | Reorganize for nutrition labeling suitable for the Japanese market. |
| Not converting Sodium to salt equivalent | Showing sodium values from overseas labels as-is may not match Japanese labeling standards. | Sodium values, conversion formula, salt equivalent, display units, rounding | Convert to salt equivalent and retain documentation supporting the conversion. |
| Relying only on Serving size labeling | Serving size on overseas labels may not correspond with the display units required in Japan. | Serving size, per 100g, per package, net content | Confirm the display units required for the Japanese market. |
| Labeling as low-carb or reduced sugar | Additional verification of criteria and comparison conditions is needed for nutrition claims. | Carbohydrate amount, total carbs, dietary fiber, comparison targets, supporting documents | Check criteria and evidence for the claim, and avoid ambiguous expressions. |
| Labeling as reduced salt | Claims indicating reduction must address comparative products and reduction levels. | Salt equivalent, comparison products, reduction rate, documentation of standard products | Clarify comparison conditions and keep supporting documents. |
| Labeling as high protein | Claims of high content must meet defined criteria. | Protein amount, labeling standards, analytical data, amount per package | Confirm standards and display units before labeling. |
| Strong health claims in advertising | Claims beyond nutrition labeling may raise issues under the Act against Unjustifiable Premiums and Misleading Representations, Health Promotion Act, and Pharmaceutical Affairs Law. | Advertising text, EC page, SNS posts, supporting documents, efficacy expressions | Separately verify food labeling and advertising expressions. |
| Displaying without ingredient table or analysis certificate | Inability to substantiate displayed values. | Ingredient table, specifications, analysis certificates, calculation basis, manufacturer documents | Obtain and retain supporting documents before import. |
Practical Scenario 1: Using Overseas Nutrition Facts on Japanese Labels
For example, when importing snacks from overseas manufacturers that have Nutrition Facts displayed, importers may attempt to directly transcribe that information onto Japanese labels.
In such cases, it is necessary to check whether items such as Serving size, Calories, Sodium, and Total Carbohydrate on the overseas label correspond with the required display items, order, units, and ingredient names in Japanese nutrition labeling. Even if the overseas label shows values per serving, different display units may be required for the Japanese market.
In particular, Sodium needs to be confirmed as salt equivalent for Japan. Instead of directly translating overseas values, it is important to convert them into figures suitable for Japanese labels and keep documentation supporting this conversion.
Practical Scenario 2: Promoting Low-Carb on Sales Pages
When displaying terms such as “Low-Carb,” “Reduced Sugar,” or “Recommended for Dieting” on e-commerce pages for imported foods, simply appearing to have low sugar content is not sufficient.
Claims related to low-carb or reduced sugar need to be reviewed as nutrition claims or advertising claims. This requires confirmation of carbohydrate, sugar, dietary fiber values, comparison targets, reduction rates, display units, and supporting documentation.
Furthermore, if expressions such as “lose weight just by drinking” or “improves body constitution” are used alongside such claims, issues under the Act against Unjustifiable Premiums and Misleading Representations, Health Promotion Act, and Pharmaceutical Affairs Law could arise. It is important to separately verify the nutrition values and advertising expressions.
Practical Scenario 3: Making Reduced Salt Claims
When labeling imported soups or seasonings as “Reduced Salt,” it is necessary to review the relationship with the comparable standard or conventional product.
Simply feeling that the salt equivalent is lower is insufficient as a basis for reduced salt claims. Confirmation of the comparative product, salt equivalence of the standard product, reduction percentage, display units, analytical data, and specifications is required.
Additionally, an overseas manufacturer’s “Low Sodium” label does not necessarily mean it can directly be labeled as “Reduced Salt” for the Japanese market. Japanese labeling standards, conversions, and comparison conditions must be confirmed, and supporting documents kept before making the labeling decision.
4-Column Judgment Checklist
| Verification Stage | Party to Confirm With | Items to Confirm | Actions if Issues Are Found |
|---|---|---|---|
| Before selling imported food products | Importer, Overseas Manufacturer, Labeling Person | Food category, general-use or commercial-use, processed food or fresh food | Check whether the product is subject to labeling obligations or if labeling may be omitted. |
| When checking overseas labels | Overseas Manufacturer, Importer, Labeling Person | Nutrition Facts, Serving size, Sodium, Calories, Ingredient names, Units | Do not use as-is for Japanese labeling; convert and reorganize accordingly. |
| When creating nutrition fact labels | Labeling Person, Quality Control, Manufacturer | Calories, Protein, Fat, Carbohydrates, Salt equivalent, Display order, Units | If there are missing items or unit discrepancies, obtain additional documentation. |
| When deciding the numeric values to display | Manufacturer, Testing Laboratory, Quality Control | Analysis values, calculated values, reference values, specifications, certificates of analysis, calculation basis | Keep underlying documents and confirm consistency with displayed values. |
| When Sodium is displayed | Overseas Manufacturer, Labeling Person, Quality Control | Sodium values, conversion to salt equivalent, labeling units, rounding method | Organize as salt equivalent value for Japanese labeling. |
| When making nutrition claims | Importer, Labeling Person, Advertising Person, Expert | Criteria and supporting documents for claims such as low calorie, reduced sugar, reduced salt, high protein | If criteria are not met, revise or remove such claims. |
| When creating advertisements or e-commerce pages | Sales Person, Advertising Person, Importer, Expert | Health benefits, diet claims, improvement claims, relation to Act against Unjustifiable Premiums and Misleading Representations, Health Promotion Act, Pharmaceutical and Medical Device Act | Avoid excessive health claims and cross-check claims with supporting evidence. |
| Final check before starting sales | Importer, Labeling Person, Quality Control, Sales Person | Consistency of labeling on the package, e-commerce pages, advertisements, SNS, and in-store POP | Correct discrepancies between media and keep evidence for labeling claims. |
Common Misunderstandings
| Misunderstanding | Correct Understanding | Practical Notes |
|---|---|---|
| If a Nutrition Facts panel exists on the overseas label, it can be used as-is in Japan | Overseas labeling items, order, units, conversions, and rounding methods may differ from Japanese standards. | Nutrition facts should be reorganized according to Japanese labeling standards. |
| Sodium can be labeled as sodium directly | In Japan, the salt equivalent must be checked and displayed. | Keep the conversion basis documentation. |
| Small imported food products do not require nutritional labeling | Whether labeling is mandatory or can be omitted depends on food category, sales format, and business conditions. | Check conditions for small-scale operators and omission rules. |
| Voluntary display means free choice of labeling content | Even for voluntary nutrition facts, labeling must comply with standards. | Verify labeling items, units, and supporting documentation. |
| Claims such as "reduced sugar" or "low salt" as advertising expressions don’t require standard confirmation | If these are nutrition claims, criteria and comparison conditions must be confirmed. | Check standards and supporting evidence before labeling. |
| If there is an ingredient list, a certificate of analysis is unnecessary | Ingredient lists, specifications, certificates of analysis, and calculation bases are all needed to verify displayed values. | Keep a record of which documents were used as evidence for the labeling. |
| If the label is correct, advertising expressions are also acceptable | Excessive health claims in advertisements, e-commerce, or SNS may have issues under different regulations. | Check labeling and advertising separately. |
Practical Notes
When verifying nutrition labeling, confirm whether the product is subject to labeling obligations, whether required items are present, whether units are appropriate, and if supporting documents for numeric values exist.
For imported foods, it is important to obtain ingredient lists, specifications, and certificates of analysis from overseas manufacturers before import, and organize necessary information for Japanese label creation. Nutrition labeling should be reviewed at the early stage of sales preparation rather than after customs clearance.
When making nutrition claims, in addition to regular nutrition labeling, confirm criteria, comparison targets, reduction rates, and supporting documents separately. When emphasizing health benefits in advertising or sales pages, also verify compliance with the Act against Unjustifiable Premiums and Misleading Representations, the Health Promotion Act, and the Pharmaceutical and Medical Device Act.
Importance of Record Keeping
For nutrition labeling, it is essential to preserve supporting documentation for the displayed values. If asked after sales begin, one must be able to explain which documents were the basis for calculations, conversions, and final values.
Documents to keep include overseas manufacturers’ ingredient lists, specifications, certificates of analysis, Nutrition Facts panels, sodium conversion documents, calculation sheets, label drafts, records of labeling revisions, verification documents for nutrition claims, and records of advertising expression reviews.
Having records makes it easier to explain and amend labeling if needed. Conversely, if evidence is lacking, it may be difficult to justify the displayed values even if they are accurate.
Summary
Nutrition labeling is a system to clearly inform consumers of the calorie and nutrient content in food products.
Nutrition labeling confirmation is generally required for general-use processed foods and general-use additives. For imported foods, overseas labels and Nutrition Facts panels should not be directly translated; instead, labeling items, units, conversions, and rounding should be adjusted to comply with Japanese food labeling standards.
When making nutrition claims, it is important to check the standard values and reference materials for each expression, such as low-calorie, reduced sugar, low sodium, and high protein. Additionally, if health benefits are strongly emphasized in advertisements or e-commerce pages, attention should be paid to compliance with the Act against Unjustifiable Premiums and Misleading Representations, the Health Promotion Act, and the Pharmaceuticals and Medical Devices Act.
In importing food practical work, it is crucial to organize the ingredient list, specifications, certificates of analysis, sodium conversion data, labeling drafts, and advertising expressions before starting sales, and to verify them from both the perspectives of nutrition labeling and sales representation.
