Questions businesses ask
- Is there a supplement law in Japan?
- No separate one. Supplements are food under the Food Sanitation Act and the Food Labelling Act. A product that reads as a medicine falls under the Pharmaceuticals and Medical Devices Act instead.
- Can a supplement make a health claim in Japan?
- Only as a Food for Specified Health Uses (FOSHU), a Food with Nutrient Function Claims or a Food with Function Claims. Other foods may not show effects or functions.
- What is a Food with Function Claims?
- A food whose business notifies the CAA Commissioner, before sale, of the scientific evidence for its safety and function. The State does not review it; the business is responsible for the claim.
- How far ahead must a function claim be notified?
- At least 60 days before the planned start of sale, not counting administrative holidays, through the CAA's notification database.
- Does FOSHU need approval?
- FOSHU needs the State's review of effectiveness and safety and permission for each product under Article 43(1) of the Health Promotion Act.
- Do Foods with Nutrient Function Claims need a licence?
- No. They are self-certified, but the daily intake must sit within set upper and lower limits and the label must show the set function and precautions.
- Is GMP required for supplements in Japan?
- For Foods with Function Claims in tablet, capsule and similar forms made from natural extracts, a manufacturing standard set by Cabinet Office Notice No. 108 of 2024 applies.
- Are function-claim notifications public?
- Yes. What a business notifies, including the evidence for safety and function and the production and quality control information, is published on the CAA's website.
- Do supplements need an import notification?
- Yes. They are food, so each import for sale is notified to an MHLW quarantine station under Article 27 of the Food Sanitation Act.
- Can a supplement advert promise health effects?
- Not where the representation is significantly contrary to fact or misleading (Health Promotion Act, Article 65), and the CAA has warned against adverts that go beyond what was notified.
- How does Compliant Always help with selling in Japan?
- Our team reads the rules for the markets you sell in, including the Japanese-language sources. Compliant Always shows which apply to your product, keeps the documents behind each one ready, and watches the sources for changes. It shows what the requirements say and what your documents show; you decide.
