Japan remains a highly attractive market.
However, in practice, the most common hurdle is not ingredients—but claims.
Claims that are commonly used in Korea may be restricted in Japan,
and in some cases, the same product may even need to be reclassified as a
quasi-drug.
In the Japanese market, category selection itself becomes a strategic
decision.
|
point 1
|
Is There No "Brightening" Category in Japan?
|
|
Strictkly speaking, there is no "Brightening" category within cosmetics in Japan.
These are defined as quasi-drug claims.
Inhibition of melanin production
Prevention of spots and freckles
Cosmetics, on the other hand, are designed based on appearance and physical effects,
such as:
Preventing spots and freckles caused by sun exposure (via UV
protection)
In other words, even with the same formula,
the development strategy changes depending on how the claim is expressed.
|
point 2
Cosmetics or Quasi-drugs?
|
|
Cosmetics are products designed to provide overall, gentle benefits such as
moisturizing and cleansing the skin. They can be launched relatively quickly, but
claims about efficacy are limited.
Quasi-drugs are formulated based on active ingredients to deliver specific functions
such as acne prevention, brightening, or wrinkle improvement. While functional
claims are allowed, they require pre-approval.
The key point is,
Quasi-drugs are not always the better
option.
Due to:
Restrictions on active ingredients and formula
Longer development timelines
Additional regulatory costs and approval processes
They may become a constraint, especially for projects where speed and flexibility
are critical.
|
point 3
|
Where Do Sunscreens Fall?
|
|
In Japan, UV filters are not recognized as 'active ingredients' in quasi-drugs.
They are classified as additives. This means, a product that only claims UV
protection can be marketed as a cosmetic without pre-approval. However, if
additional functional claims are made—such as anti-acne and brightening, the product
must be approved as a quasi-drug, based on active ingredients.
Therefore, standalone sunscreen products can be efficiently developed as cosmetics,
allowing faster market entry without the burden of approval processes.

point 4
|
Regulation-Driven Formulation & Claim Design
|
|
A common issue in Japan-bound projects is straightforward.
The product is developed as a cosmetic, but the claims align with quasi-drug-level
efficacy.
This mismatch often leads to reclassification of the product category, claim
revisions and changes in development direction resulting in delays and additional
costs.
The key is simple.
Formulation, ingredients, and claims must be designed as one integrated
structure.
In the Japanese market, both category selection and claim scope must
be defined at
the early development stage to avoid unnecessary rework.
Japan is a market where products are ultimately defined by how they are claimed
and categorized.
At OTCM, we support Japan market entry by integrating formula development with
regulatory and claim strategy from the outset.
