Selling supplements in Japan: FOSHU, FFC and the food model

Japan is a large, sophisticated market with a distinctive system of food-with-health-claims categories. For a manufacturer, the opportunity lies in understanding which claims framework fits the product — a structure with no direct EU equivalent.

How supplements are classified

In Japan, supplements are generally sold as foods, with several routes for health claims: Foods for Specified Health Uses (FOSHU), Foods with Function Claims (FFC), and Foods with Nutrient Function Claims. Each has its own evidence and notification requirements, and ordinary 'health foods' without these designations may not carry function claims.

The regulator

In Japan, the competent authority is the Consumer Affairs Agency (CAA) and the Ministry of Health, Labour and Welfare (MHLW). Knowing the regulator is the starting point: it determines how a product enters the market, who enforces the rules, and where to look for authoritative guidance.

Getting to market

Plain supplements sold as foods do not require pre-market approval, but to make function claims a product typically uses the FFC route (notification with supporting evidence to the CAA) or FOSHU (a more demanding individual approval). Choosing the right claims route is the central strategic decision.

What makes Japan distinct

The defining feature is the claims architecture: FOSHU (approved), FFC (notified with evidence), and nutrient function claims each unlock different wording. Japanese-language labelling and local importer arrangements are required. The system rewards a clear decision on which claims framework the product will use before launch.

Labelling and language

The label must be in Japanese and follow the requirements of the chosen claims route. Beyond language, the label has to carry the market-specific mandatory information — the right claim wording, the correct nutrition or supplement format, and any registration or licence identifiers the regime requires.

Because national requirements, registration procedures and permitted ingredients change and differ in detail, confirm the current rules for Japan with the competent authority or a local regulatory expert rather than relying on a general summary.

One formula, many markets — the software argument

The deeper point is that Japan is not the EU, and a market like this is exactly where a single source-of-truth formula proves its worth. The same underlying formula has to be expressed in a completely different way here — a different claims framework, a different label format, a different registration dossier, a different language — while still tracing back to the same recipe that serves Europe and every other market. Managing that as one structured formula with market-specific outputs, rather than rebuilding the product from scratch for each country, is what makes genuinely global expansion sustainable.

Where Lemoniq fits

Lemoniq holds each product as one structured formula and generates the market-specific outputs a Japanese launch needs — the right label format and language, the ingredients and levels checked against local rules, and the documentation a registration or notification expects — from the same source that serves every other market. Expanding into Japan becomes a configuration of an existing formula, not a fresh product.

The takeaway

Selling supplements in Japan means working within its own classification, its own regulator and its own market-entry route — which look nothing like a simple copy of an EU launch. The manufacturers who expand globally without drowning in duplicated work are the ones whose one formula generates each market's label, ingredients check and documentation automatically.

Lemoniq turns one formula into compliant outputs for Japan and markets worldwide at once. We solve this exact problem. See how it works
