OEM Manufacturing and Japanese Trademarks: Who Should Own Your Brand in Japan?

"The factory has made our products for years — we trust them."
"We are only an OEM supplier. The Japanese buyer will handle the trademark."
"Our brand is registered at home, so we are covered in Japan."

OEM and ODM manufacturing is how most products reach Japanese shelves and Amazon Japan listings. Yet in many of these deals nobody has clearly decided who should own the Japanese trademark — the brand owner, the factory or the Japanese distributor. When that question is left open, it usually comes back as a dispute.

This guide by Toru Kano, Japanese Patent Attorney at BrandAgent (Kyoto), covers both sides: brand owners who use contract manufacturers, and factories (including Chinese manufacturers) that sell their own brands into Japan.

Trademarks are territorial

A trademark protects you only in the country where it is registered. A Chinese, Korean or US registration gives no rights in Japan, and Japan follows a first-to-file system: in principle the person who files first gets the right, even if someone else used the name earlier.

Three typical OEM trademark conflicts in Japan

1. The factory or a trading company files the brand in Japan

The manufacturer knows the brand name, logo and product line better than anyone. If the brand owner has not filed in Japan, a factory, sourcing agent or trading company can file first — and then use the registration as leverage over pricing or exclusivity.

2. The Japanese distributor registers the mark in its own name

A distributor that launched your product in Japan may register the brand "to protect the market". When the relationship ends, you may find you cannot sell in Japan under your own brand without its consent.

3. Amazon Japan and import problems

Amazon Japan Brand Registry relies on a Japanese trademark. If the registration is in someone else's name, that person controls your brand page and can file infringement reports against your listings. Japanese trademark owners can also ask Japan Customs to stop imports of goods bearing their mark — which can hit genuine goods if the "owner" is not you.

If your agent or distributor registered your mark

Japanese law gives some remedies to the true owner. Under Article 53-2 of the Trademark Act, if an agent or representative registers the owner's mark without consent, the owner of the mark in a Paris Convention country can request cancellation — but only within 5 years of registration. Opposition (within 2 months of the registration gazette) and invalidation trials may also be options, for example for applications made in bad faith.

These procedures take time and evidence. Filing first is far cheaper than recovering a mark later.

Checklist for brand owners using OEM/ODM factories

• File your Japanese trademark before you share designs or start sampling with a factory or Japanese partner.
• State in the OEM/ODM contract that all trademarks belong to you and that the factory will not file them anywhere.
• Check J-PlatPat for your brand now; if someone has filed, act quickly while opposition is still possible.
• If you manufacture in China, also consider a Chinese trademark — we coordinate with trusted Chinese agents.
• Register in the classes you actually sell (and those Amazon categories require).

Checklist for factories selling their own brand into Japan

• If the brand is yours, file in Japan in your company's name — not in the name of a Japanese buyer or individual.
• If you produce for a Japanese brand owner, do not file their brand; it damages trust and can be cancelled.
• Keep evidence of creation and use (design files, invoices, catalogues) in case of a dispute.
• Before exporting under a new brand, run a Japanese clearance search so you do not infringe an existing mark.

How to file in Japan from overseas

• Applicants without an address in Japan must file through a Japanese patent attorney.
• Direct filing or a Madrid designation of Japan; Paris priority within 6 months of your home filing.
• Your company name and address in the original language and in English; we handle the Japanese.
• Examination about 9–12 months; accelerated examination about 2–3 months.
