A formula that clears every ingredient check in your home market can still stall in Japan, because Japan’s additive system is not a translation of the EU’s or the US’s — it is a separate legal structure with its own list, its own labelling rules and its own use-limit standards. Two additives can look identical on paper and still sit on opposite sides of what a Japanese factory can put in a product.
This guide sets out Japan’s four food additive categories, the rule that every additive must be declared on the label, how use-limit standards work, and where Japan, the EU and the US genuinely diverge — so a brand can see early which parts of a formula need rechecking for a Japan-made product.

Japan’s four additive categories
Japan places every food additive into one of four legal categories, and which category an additive sits in decides how it was approved and how it must be labelled.
| Category | What it covers | How it got there |
|---|---|---|
| Designated additives (指定添加物) | Chemically synthesised and some natural substances individually approved | Reviewed and designated one by one by the health ministry, based on a safety assessment by the Food Safety Commission of Japan |
| Existing food additives (既存添加物) | Natural substances with a long history of use in Japan | Grandfathered onto a fixed list when the category was created in the 1995 revision of the Food Sanitation Act; no new substances are added to this list |
| Natural flavourings (天然香料) | Natural substances extracted from plants or animals to add fragrance, used at minimal levels | Listed by source material on the Natural Flavouring Original Substance List (over 600 entries) |
| General food additives (一般飲食物添加物) | Ordinary foods also used for an additive function, such as strawberry juice used as a colourant | Covered by their status as recognised foods, not through individual designation |
An ingredient must sit in one of these four categories, or have a specific exemption, before a Japan-made product can contain it. There is no general “permitted unless banned” default the way some export markets work.
The rule that additives must be labelled
Japan’s Food Labelling Standards require essentially every added food additive to appear in the ingredient list, and eight specific functions must also carry a use-category word in front of the substance name.
Additives used as a sweetener, colourant, preservative, thickener/stabiliser/gelling agent, antioxidant, colour fixative, bleaching agent or fungicide must be written as “(use-category) (substance name)” — for example, “sweetener (sucralose)”. Every other additive is written by substance name alone. There is no blanket exemption for substances that serve only a processing role, the way some other markets treat processing aids.
Use-limit standards
Some additives may be used in any amount needed for the intended effect, while others carry a specific use standard naming the target foods and the maximum permitted level.
Japan’s official compilation, “Specifications and Standards for Food Additives,” sets compositional specifications for individual additives plus manufacturing and use standards where they apply. Only a subset of designated additives carry a formal use standard (a maximum level tied to specific food categories); the rest may be used according to good manufacturing practice, without a numeric ceiling. Designating a new additive, or revising a use standard, requires a risk assessment by the Food Safety Commission of Japan followed by review by the health ministry — the same two-step process used for the original designation.

How this differs from the EU and the US
The EU authorises additives individually under a positive list with an E-number, and the US relies mainly on a GRAS determination rather than case-by-case designation — neither system maps directly onto Japan’s four categories.
| System | How an additive gets approved | What that means in practice |
|---|---|---|
| Japan | Assigned to one of four categories; new synthetic or novel substances go through individual designation reviewed by the Food Safety Commission of Japan and the health ministry | An additive with no Japanese designation, and no existing-additive or general-food-additive status, cannot be used, regardless of its status elsewhere |
| EU | Positive list under Regulation (EC) No 1333/2008; new additives are evaluated by the European Food Safety Authority and authorised under Regulation (EC) No 1331/2008, then assigned an E-number | An additive not on the EU list cannot be used even if it is permitted in Japan or the US |
| US | Substances are either individually approved as food additives through an FDA petition, or self-determined (or FDA-notified) as Generally Recognized as Safe (GRAS) based on a documented expert consensus | GRAS status can be reached without the multi-year premarket petition process that a formal food additive approval requires |
The three systems do not always agree even on long-established substances. Titanium dioxide, for example, is still permitted as a food additive in Japan and the US, but has been banned in the EU since 2022 after the European Food Safety Authority could not rule out a genotoxicity risk. Erythrosine (also known as FD&C Red No. 3) has long been restricted in Japan and the EU, and the US FDA revoked its authorisation for food use in January 2025, with compliance required by January 2027. A colourant, preservative or processing aid chosen for one market’s rules can be the wrong choice, or simply unavailable, in another.
Why one formula may need to change for a second market
A formula legal in your home market is not automatically legal in Japan, or vice versa, so the additive line of the specification has to be rechecked market by market, not assumed to travel.
The gap shows up in three places: an additive permitted in one market but not designated, existing, or general-food in Japan; a use-limit standard in Japan that is stricter (or looser) than your home market’s limit for the same food category; and a labelling difference, such as Japan’s eight use-category words, that changes how the ingredient list must read even when the substance itself is fine everywhere. None of these is usually a reason to abandon a formula — it is a reason to build the specification with the destination market named from the start, so the substitution (if one is needed) happens on paper before it happens on the production line.
Before you ask for a quotation
- Full list of additives in the formula, by substance name (not just function)
- Countries you will sell the finished product into
- Whether any additive in the current formula is chosen for a reason specific to your home market’s rules (an E-number equivalent, a GRAS status, a particular colour)
- Any use-category labelling already used on your current label, to compare with Japan’s eight-function rule
- The food category the product will be labelled under, since some Japanese use standards are food-category specific

Frequently asked questions
1. What are Japan’s four food additive categories?
Designated additives (individually approved), existing food additives (grandfathered natural substances), natural flavourings, and general food additives (ordinary foods also used as additives). Every additive in a Japan-made product must fall into one of these.
2. Do all food additives have to appear on a Japanese label?
Yes. Essentially every added food additive must appear in the ingredient list by substance name, and eight specific functions — sweeteners, colourants, preservatives, thickener/stabiliser/gelling agents, antioxidants, colour fixatives, bleaching agents and fungicides — must also carry a use-category word.
3. Does every additive in Japan have a maximum use level?
No. Only a subset of designated additives carry a formal use standard tying them to specific food categories and maximum levels; others are used according to good manufacturing practice without a numeric ceiling.
4. Is the EU’s E-number system the same as Japan’s additive list?
No. They are separate legal systems with separate lists. An additive with an E-number in the EU is not automatically permitted in Japan, and a Japanese-designated or existing additive is not automatically on the EU’s positive list.
5. Is US GRAS status the same as a Japanese additive approval?
No. GRAS is a US determination, often reached without the multi-year petition process a formal US food additive approval requires, and it has no bearing on whether the same substance is designated, existing, or otherwise permitted in Japan.
