Domain Names, Social Media Handles and Trademarks in Japan: Why You Need the Japanese Trademark First

"We already own the .com domain and our Instagram and TikTok handles. Do we still need a trademark in Japan?" "Someone registered our brand name as a .jp domain — what can we do?" "A Japanese-language account is pretending to be our official store."

Overseas brand owners and cross-border sellers often secure their online names long before they think about trademarks. That makes sense for marketing, but in Japan a domain name or a social media handle gives you very little legal protection on its own. When a problem appears, the first question platforms, dispute panels and courts usually ask is: do you have rights in that name in Japan?

In this article, Japanese Patent Attorney Toru Kano of BrandAgent explains how domain names, social media handles and Japanese trademarks fit together, how .jp domain disputes are resolved, and why the Japanese trademark should come first.

Foreign applicants file through a Japanese patent attorney

A company or individual without a domicile or business office in Japan must file a Japanese trademark application, and handle later procedures, through a representative in Japan — in practice a Japanese patent attorney (Benrishi). You do not need a Japanese subsidiary or a Japanese address. We communicate in English and Chinese and accept payment by PayPal (in JPY) or bank transfer.

A domain name or SNS handle is not a trademark right

Domain names and social media usernames are allocated on a first-come, first-served basis by registrars and platforms. Nobody checks whether you own the brand, and registering one does not create any exclusive right to use the name for goods or services.

A Japanese trademark right, by contrast, arises only when the mark is registered at the Japan Patent Office (JPO). It gives the owner the exclusive right to use the mark for the designated goods and services in Japan, and the right to stop others from using identical or similar marks for identical or similar goods and services. Japan is a first-to-file country: in principle, the first person to file gets the registration, even if someone else used the name online earlier.

Owning yourbrand.com therefore does not stop a third party from registering your brand as a trademark in Japan. If that happens, the third party could even object to your own use of the name in Japan, including on your Japanese website or marketplace listings.

Four problems overseas brands commonly face in Japan

1. Someone registers your brand as a .jp domain

A third party registers yourbrand.jp or yourbrand.co.jp, sometimes to sell it back to you, sometimes to redirect Japanese customers elsewhere. This can be addressed through the JP-DRP (explained below), but your position is much stronger if you hold rights in the name.

2. Impersonation accounts on social media

Japanese-language accounts that use your logo and brand name, post your product photos and direct users to a fake store. Japanese consumers may believe it is your official Japan account.

3. Copycat online stores and marketplace listings

Websites that copy your design, or sellers who list look-alike products under your brand name on Japanese marketplaces.

4. Your brand is filed as a trademark in Japan by someone else

This is the most serious one, because it can turn the other three around: the third party becomes the trademark owner in Japan and you become the one who has to defend yourself. Japanese law does have tools against bad-faith filings — for example, Article 4(1)(xix) of the Trademark Act refuses registration of a mark identical or similar to another person's mark that is well known in Japan or abroad, where it is used for an unfair purpose — but proving that your mark is well known and that the filing was made for an unfair purpose takes evidence, time and cost, and success is not guaranteed.

.jp domain disputes: the JP-DRP

Disputes over JP domain names can be resolved under the JP Domain Name Dispute Resolution Policy (JP-DRP), established by JPNIC and modelled on the international UDRP. It is part of the registration rules, so every .jp registrant is bound by it.

According to the JP-DRP, the complainant must show all three of the following:

• The registrant's domain name is identical or confusingly similar to a trademark or other indication in which the complainant has rights or legitimate interests;
• The registrant has no rights or legitimate interests in respect of the domain name; and
• The domain name has been registered or is being used in bad faith.

Points foreign brand owners should know:

• Remedies are limited to cancellation of the domain name or its transfer to the complainant. Damages are not available in this procedure.
• Provider: the Japan Intellectual Property Arbitration Center handles JP-DRP complaints.
• Language: the default language of proceedings is Japanese, so your complaint and evidence generally need to be prepared in Japanese.
• Courts remain available: either party can go to court, and if the registrant files a lawsuit within the period set by the policy after a transfer or cancellation decision, implementation is withheld.

The first requirement is where a Japanese trademark registration helps most. A registration is clear, official evidence of your rights in the name in Japan. Without it, you have to prove rights in other ways, which is harder and more expensive. For generic top-level domains such as .com, a different procedure, the UDRP, applies, and WIPO is one of its providers (wipo.int).

Domain dispute rules and provider procedures are updated from time to time, so check the latest version with JPNIC and the provider before filing a complaint.

Impersonation accounts and copycat stores

Most major social media platforms and marketplaces have their own procedures for reporting impersonation and trademark infringement. The details — which forms to use, what evidence is accepted, whether a pending application is enough — differ by platform and change often, so always check the platform's latest guidelines.

What is common in practice is that a trademark registration number makes a report much easier to process. A report of "trademark infringement" is naturally stronger when you can show a registration in the country where the infringing account or store targets customers. A registration certificate in another country may not be accepted for activity aimed at Japan.

For Amazon.co.jp, Amazon's Japanese Brand Registry page currently states that a pending or registered trademark (word mark, or image mark containing words, letters or numbers) issued by the relevant government trademark office is required. If you plan to sell on Amazon.co.jp, a Japanese application is therefore the starting point. Other marketplaces have their own rules; check each one before you rely on it.

For a website that copies your brand, a Japanese trademark also gives you a basis for warning letters and, if necessary, legal action in Japan. Japan's Unfair Competition Prevention Act also contains provisions on acquiring or using domain names similar to another's indication for wrongful gain, but relying on it generally requires showing that your indication is protected in Japan — again, evidence that is much easier to present with a registration.

What to file in Japan, and in what order

• The name as it appears in your domain and handles (usually the Latin-letter brand name), as a standard-character word mark.
• Your logo, if you show it prominently on your website, profile icons and packaging.
• A katakana version, if Japanese customers will search for or call your brand in katakana.

Choose classes based on the products you sell in Japan, plus closely related goods you plan to add. Online retail itself is usually covered through the goods you sell; retail services in Class 35 can be considered where relevant. If you have a home-country application filed within the last 6 months, you can claim Paris Convention priority.

If you also want to secure yourbrand.jp, do so early. Registration conditions for .jp domains are set by the registry, so check them with JPRS or your registrar.

FAQ

• Q. We have used our brand online for years. Does that give us rights in Japan?
  A. Generally not by itself. Japan is a first-to-file country, and protection for unregistered marks is limited and depends on proving that the mark is well known. Registration is the reliable route.
• Q. Can we file a JP-DRP complaint without a Japanese trademark?
  A. The policy refers to a trademark or other indication in which you have rights or legitimate interests, so it is not strictly limited to Japanese registrations. In practice, a Japanese registration makes the first requirement much easier to prove.
• Q. Is a pending Japanese application useful?
  A. Yes, for some purposes. For example, Amazon's Japanese Brand Registry page states that a pending application can be used. Other platforms may require a registration — check their latest rules.
• Q. Should we register our SNS handle itself as a trademark?
  A. Register the brand name that the handle uses. If the handle contains extra words such as "official" or "japan", the core brand name is what matters.
• Q. Can we communicate in English or Chinese?
  A. Yes. We have handled more than 4,000 trademark applications, and every case is handled personally by the licensed patent attorney, in English or Chinese.
