Organic cosmetics are a global market, but Japan has no certification scheme for organic cosmetics, so the label is close to self-declared. This article sets out how the situation differs from the certifications you may know from home, and what to look for on a Japanese shelf.
| Item | Japan | Overseas (examples) |
|---|---|---|
| Definition of organic cosmetics | No official definition or certification | COSMOS (EU, private): sets the share of organic ingredients, etc. ／ USDA Organic (US Department of Agriculture; applies its food standard to cosmetics) ／ ECOCERT, NATRUE and others |
| "Organic JAS" (有機JAS, Japan's organic food mark) | Food and agricultural products only. Cannot be used on cosmetics | — |
| "Natural", "nature-based" (自然派), "plant-derived" | No definition | ISO 16128 (a method for calculating a natural-origin index; not a certification) |
| Regulation of claims | The Act against Unjustifiable Premiums and Misleading Representations (景表法, Japan's consumer advertising law) — unsupported claims of superiority are prohibited; the Japan Cosmetic Industry Association's advertising guidelines | Each country's advertising rules |
| Safety | Organic or natural origin has no link to mildness. Allergy to essential oils and plant extracts is well known to dermatologists | The same |
[Verify] Check the scope of Organic JAS with the Ministry of Agriculture, Forestry and Fisheries, the content of ISO 16128 in the Japan Cosmetic Industry Association explanation, and the approach of the Premiums and Representations Act with the Consumer Affairs Agency.
Japan has no organic certification for cosmetics. Without an overseas certification mark (COSMOS etc.) it is self-declared.
Natural ingredients (essential oils, plant extracts) are among the main causes of allergy. "Gentle" and "natural" are unrelated, and synthetic ingredients are sometimes less irritating.
It is a figure calculated under ISO 16128, and water counts as natural-origin. The remaining 5% does not mean "dangerous"; it is usually necessary ingredients such as preservatives.
Without preservatives, microbes multiply more easily and the product keeps for less time after opening. They assume small sizes, refrigeration and quick use (see the additive-free article).
A cosmetic may claim only the 56 permitted items, organic or not. It cannot claim to "heal" or to "work", and price and efficacy are separate things.
