Misleading Quality Representation

Overview

Misleading quality representation refers to a display or advertisement that may cause general consumers to misunderstand that the quality, standard, content, origin, production method, function or safety of a product or service is significantly better than it actually is.

In Japan, this is one type of unjustifiable representation regulated under the Act against Unjustifiable Premiums and Misleading Representations. It is especially important in food, health food, supplement, natural product and imported product advertising.

For imported foods, the risk is not limited to the product label. Product pages, online advertisements, social media posts, brochures, in-store POP displays, ranking claims, comparison charts, images and translated overseas marketing materials may also be reviewed.

Why This Matters for Imported Foods

Imported food products often come with marketing materials prepared by overseas manufacturers. These materials may include claims about quality, origin, ingredients, health benefits, manufacturing methods, safety or natural characteristics.

However, claims that are acceptable or common in the exporting country may create problems under Japanese rules when used for consumers in Japan.

Importers, distributors and sellers should not simply translate overseas product descriptions into Japanese or English for the Japanese market. They need to check how consumers in Japan may understand the overall impression of the claim.

Food Advertising Claims That Often Create Risk

The following types of expressions may require careful review in food advertising:

• “Highest quality”
• “Completely additive-free”
• “Made only from natural ingredients”
• “Doctor recommended”
• “Scientifically proven”
• “Industry-leading standard”
• “Japan’s only product of this kind”
• “No. 1” or ranking-based claims
• “Better than conventional products”

These expressions are not always prohibited. However, the advertiser must be able to explain what the claim means, what evidence supports it, and whether the evidence matches the actual wording and consumer impression.

Health and Function Claims

Food advertising becomes more sensitive when the claim suggests a health effect, functional benefit or disease-related effect.

Expressions such as “you can become healthy just by drinking this,” “improves your constitution in a short period,” “prevents illness,” or “improves the internal body environment” may raise issues not only under fair labeling rules, but also under the Health Promotion Act and the PMD Act.

For foods, care is needed to avoid expressions that may be viewed as false or exaggerated health claims, or as drug-like efficacy claims.

This is particularly important for supplements, health foods, functional foods, natural foods and products marketed with wellness-related messaging.

Origin, Ingredient and Manufacturing Claims

Misleading quality representation may also arise from claims about origin, ingredients, manufacturing method, nutritional characteristics or product quality.

For example, an advertisement may give consumers the impression that the product uses a special ingredient, comes from a particular region, follows a superior manufacturing process, or has a higher quality grade than is actually supported by the product specifications.

Even if each individual word is technically true, the overall impression created by photographs, layout, emphasis, icons, comparison tables or slogans may still be questioned.

Substantiation Requirement

For claims about effect, performance or quality, reasonable supporting evidence is important.

Under Japan’s substantiation system for advertising claims, the Consumer Affairs Agency may request the business operator to submit materials that provide reasonable grounds supporting the representation.

If the operator cannot submit the requested materials, or if the submitted materials are not considered reasonable grounds for the claim, the representation may be treated unfavorably in enforcement procedures.

Possible supporting materials may include analysis certificates, test results, product specifications, manufacturing process documents, origin certificates, third-party evaluations, research data or sales records. However, simply having documents is not enough. The scope of the documents must match the actual claim being made.

Comparative Advertising

Comparative advertising is not automatically prohibited in Japan. However, comparison claims must be carefully supported.

Claims such as “better than other products,” “industry-leading,” “Japan’s first,” “only product in Japan,” or “significantly improved compared with the previous product” require clear comparison targets, comparison conditions, research methods and supporting evidence.

If the comparison basis is unclear, or if similar products exist despite a “unique” or “only” claim, the display may create a misleading impression.

Difference From Misleading Advantageous Representation

Misleading quality representation concerns the quality, standard, content or characteristics of a product or service.

Misleading advantageous representation concerns price, discount rate, transaction terms, campaign conditions or other commercial advantages.

In food sales, quality, ingredients, origin, manufacturing method, function and health-related claims are usually reviewed as quality-related issues. Price, discount, limited quantity, limited period and campaign conditions are usually reviewed as transaction-condition issues.

Practical Points for Imported Food Businesses

When checking imported food advertisements, businesses should review not only the wording but also the overall consumer impression.

Photographs, charts, rankings, customer testimonials, expert comments, comparison tables, icons, package design, image text and social media captions may all affect the impression given to consumers.

Imported food businesses should avoid using overseas manufacturer materials without local review for Japan. Product labels, e-commerce pages, advertisements, social media posts, campaign pages and in-store displays should be checked together before sale.

Checklist Before Use

Before using a food-related quality or function claim in Japan, check the following points:

• Does the claim match the actual product content, quality, standard, ingredients, origin and manufacturing method?
• Is there reasonable supporting evidence for health, function or performance claims?
• Does the claim avoid drug-like efficacy expressions under the PMD Act?
• Does the claim avoid false or exaggerated health-related expressions?
• If comparison is used, are the comparison target, condition and research method clear?
• Is the claim merely a translation of overseas marketing material without Japanese legal review?
• Are the label, EC page, advertisement, social media post and in-store POP consistent?
• Can the business explain the claim if questioned by a regulator, customer or trading partner?

Practical Points for Overseas Suppliers

Overseas suppliers exporting food products to Japan should understand that Japanese importers may ask for evidence behind marketing claims.

This may include specifications, certificates, test results, production records, origin documents, ingredient information and explanations of how advertising claims were prepared.

A claim that sounds attractive in the exporting country may need to be softened, clarified or removed for the Japanese market.

For Japan-bound products, suppliers should cooperate with the importer before finalizing labels, product pages, advertisements or social media materials.

Common Mistakes

Common mistakes include using overseas advertising copy without review, translating health claims too directly, using “No. 1” or “only” claims without reliable support, and relying on vague certificates that do not match the actual advertising wording.

Another common mistake is focusing only on the package label while ignoring the product page, social media content, influencer posts, sales campaign pages and in-store display materials.

In practice, the overall impression of the advertisement is important. Businesses should check how an ordinary consumer would understand the entire display, not only whether each sentence is technically defensible.

Key Takeaway

Misleading quality representation is an important advertising risk for food products in Japan.

Imported foods, health foods, supplements, natural products and premium foods are especially vulnerable because overseas marketing expressions may not fit Japanese advertising and labeling rules.

Before selling or promoting food products in Japan, importers and overseas suppliers should check whether claims about quality, origin, ingredients, manufacturing method, function, safety or health benefits are accurate, supported by evidence and consistent across all sales channels.
