How to Find a Cosmetics OEM Manufacturer in Japan (Guide)

1. Know what you need: OEM or ODM

OEM means the manufacturer produces a product to your specification under your brand. ODM means they also develop the formula for you — useful if you don't have a chemist. In Japan the two usually come together: 132 of the 133 companies in our dataset offer OEM, and 123 explicitly offer formulation or product development. Ask whether they have existing ("stock") formulas you can adapt — starting from one is usually the fastest and cheapest way to a first product.

2. Check licenses before anything else

Japan has two separate cosmetics licenses, and they tell you different things:

Cosmetics Manufacturing License (化粧品製造業許可) — the company may manufacture cosmetics. 60 of the 133 list it on their website.
Cosmetics Marketing License (化粧品製造販売業許可) — the company may put products on the Japanese market and takes legal responsibility for them. 54 list it. If you also want to sell in Japan, someone must hold this license for your product; an OEM that holds it can take that role for you.

A company that shows a Marketing License but no Manufacturing License is often a planning company that subcontracts production — not necessarily a problem, but ask where the factory is. For medicated products (quasi-drugs, 医薬部外品 — e.g. whitening, anti-acne, deodorant) you need a maker with a Quasi-drug Manufacturing License; 35 list one. 41 state ISO 22716 (cosmetics GMP) certification.

3. What minimum orders really look like

74 of the 133 publish a minimum order quantity in units. Across those, the median stated minimum is 1,000 units; 54 start at 1,000 units or fewer, 35 at 500 or fewer, and 22 at 100 or fewer. 16 require 3,000 units or more.

Stated minimums are per item (per formula and container), and many makers add that the real number depends on the container and packaging you choose. Smaller runs usually mean a higher unit price. 104 of the 133 either say they accept small lots or publish a minimum of 1,000 units or fewer.

4. Plan for export early

A formula that is legal in Japan may not be legal where you sell — ingredient rules differ between the US, the EU, China and Southeast Asia. 63 of the 133 state overseas sales or export support (for example preparing export documents or adapting formulas to destination-country rules). Tell the manufacturer your target markets in the first message; it changes which formulas they will suggest.

5. Write a first message that gets answered

Only 30 of the 133 have an English website or state that they handle English inquiries, but many Japanese contact forms accept English if the message is short and concrete. Include:

What you want to make (product type, one line on the concept)
Target quantity for the first run and your timeline
Whether you need formulation (ODM) or have your own formula
Destination countries and sales channels
Your company name and website

Example
Subject: OEM inquiry — facial serum, 1,000 units, export to the US

Hello, we are [brand], a skincare brand selling online in the US. We are looking for an OEM partner in Japan for a facial serum (ODM — we would like to start from one of your existing formulas). Our first order would be about 1,000 units, with launch planned for [month]. Could you tell us your minimum order, prototype process and approximate lead time? We can communicate in English. Thank you.

6. Questions to ask before you sign

Minimum order per item, and whether it changes with container or packaging
Prototype (sample) fees and how many revisions are included
Lead time from order to shipment
Who owns the formula if you later change manufacturers
Which documents they can provide for export (ingredient lists in INCI names, certificates of analysis, etc.)
