Japan · Advertising framework
Search advertising for food supplements in Japan
General market orientation, not campaign clearance. Research scope and dates
Product and service rules
Notification of a functional food is not government approval
Regulator guidance
Foods with Function Claims use a notification route in which the operator is responsible for the scientific basis. This differs from FOSHU individual review. Identify the actual food category, permitted or notified statement and applicable conditions; do not advertise a notified product as government-approved medicine.

Check the post-transition FFC dossier
Regulator guidance
FFC reforms phase in adverse-event reporting from September 2024 and revised notification arrangements from April 2025. The transition for revised labelling and GMP requirements for specified natural-extract tablet/capsule products ended on 31 August 2026. Check whether the actual product falls within those requirements.
Verify the current notification, evidence, label and withdrawal status. Notification is not government approval of efficacy or safety; do not turn a function claim into a disease-treatment claim.

Channel rules
Check the complete consumer-facing message
Regulator guidance
The misleading-representations regime covers goods and services, including misleading impressions about quality or price advantages. Review the full presentation and offer conditions. A truthful individual detail does not justify a deceptive overall claim.

Control short copy and dynamic assets
Editorial recommendation
Approve keywords, responsive assets, sitelinks and destinations together. Disable combinations that would lose a required qualification. A landing page is not an automatic substitute for information required in the ad itself.
Campaign workflow
Food Supplements: prepare the review
Editorial recommendation
Determine whether the local category is food, natural health product, medicine or another regulated class. Match each claim to the local permitted or notified wording and its composition and use conditions. Assess captions, testimonials and images for an implied treatment or prevention claim.
Keep a traceable campaign decision
Editorial recommendation
Keep one review record linking the offer, local market status, claim evidence, exact creative, media settings and any regulatory or professional clearance. Record who checked each condition. Reopen the review when the offer, claim, source rule or execution changes.
Pre-publication checklist
- Determine whether the local category is food, natural health product, medicine or another regulated class.
- Match each claim to the local permitted or notified wording and its composition and use conditions.
- Assess captions, testimonials and images for an implied treatment or prevention claim.
- Record product or provider eligibility before approving claims.
- Archive the final creative and its evidence, permissions and review decisions.
- Assign an owner for source updates, complaints and prompt withdrawal of inaccurate material.
Scope and unresolved questions
- March 2026 sixth-edition medical advertising examples, website exemption conditions and FFC transitions have been checked. Remaining checks concern prefectural implementation, practitioner-specific and pharmacy requirements, actual product notifications and treatment disclosures, personal-information processing and each messaging technology. This pack does not supply every Japanese mandatory warning text.
- This national baseline does not review every broadcaster rule, platform policy, regional licensing condition, promotion mechanic or data-transfer arrangement. No format-specific warning dimensions or durations should be inferred where none are supplied.
Research scope, introduction and dates
Food-supplement promotion in search ads in Japan begins with local classification. A product sold as a supplement elsewhere may follow a different health-product route here; check the applicable claim conditions before adapting testimonials or benefit statements.
Search advertisements leave little space for qualifications. Review the visible copy, extensions and dynamic assets together with the destination, and establish whether the format can carry the information the advertisement requires.
General market orientation, not legal, regulatory or medical advice, a complete compliance plan or clearance of an advertisement. Actual requirements depend on the specific offer and campaign.
How to use this national baseline
Editorial overview
This framework combines researched national rules with editorial review steps. Japanese product and medical-service advertising baseline; local and product-specific implementation requires review. A visible channel workflow does not establish that the selected product or service may be advertised there. Read the category restrictions first.
The review date identifies when the cited provisions or regulator excerpts were checked. It does not mean that every local rule, exception, professional standard or platform policy has been reviewed.
