Japan Trademark Katakana: Why Foreign Brands Must Register in Japanese Script (2026)

Quick Answer

Japanese consumers automatically transliterate foreign brand names into katakana
An English trademark does NOT protect the katakana version — you must file separately
A competitor or squatter can register your katakana brand name before you
Register both the English mark AND the katakana version from the start
Each version requires a separate JPO application — same fees apply

Japan trademark katakana registration is one of the most commonly overlooked steps by foreign businesses entering Japan. Your English trademark does not automatically cover how Japanese consumers write and search for your brand.

What is Katakana and Why Does It Matter for Trademarks

Katakana (カタカナ) is one of Japan's three writing scripts. It is used almost exclusively to write foreign-origin words, brand names, and loanwords in Japanese.

When Japanese consumers encounter a foreign brand name, they instinctively convert it to katakana:

Apple → アップル (Appuru)
Nike → ナイキ (Naiki)
Starbucks → スターバックス (Sutābakkusu)

This is how Japanese consumers search for your brand online, write it in reviews, and ask for it in stores — regardless of how your brand is officially written in English.

The trademark risk:

Your English trademark registration does NOT cover the katakana version
A competitor or squatter can register the katakana version independently
Once registered by a third party, they can demand payment for the transfer — or simply block your use of your own brand name in Japan
Japan is first-to-file — whoever files the katakana version first owns the rights

Japan Trademark Cost: English + Katakana

Application	Filing fee (1 class)	Registration fee (10-year)	Total JPO fees
English mark	¥12,000	¥32,900	¥44,900
Katakana mark	¥12,000	¥32,900	¥44,900
Both versions (1 class each)	¥24,000	¥65,800	¥89,800

Each mark version is a separate application with its own filing and registration fees. Attorney fees apply per application.

Trademark Filing Process: English + Katakana Strategy

Determine your katakana transliteration — Work with your attorney to establish the most natural and commonly used katakana rendering of your brand name
Search both versions — Run a clearance search on J-PlatPat for both the English mark and the katakana version in your target classes
Consider a Japanese translation (kanji) if relevant — Some brands also register a Japanese meaning-based translation. Discuss with your attorney whether this adds value for your market
File both applications simultaneously — Submit the English mark application and the katakana application at the same time to establish the same priority date for both
JPO examination — Both applications proceed through examination independently. Each may receive separate office actions
Register both versions — Aim for registration of both marks before launching publicly in Japan

Common Mistakes

Registering English only — The most common and costly mistake. An English trademark gives zero protection over the katakana version that Japanese consumers actually use
Filing katakana after the English mark — File both simultaneously to ensure the same priority date. A gap between filings creates a window for squatters to register the katakana version first
Wrong katakana transliteration — There can be multiple ways to render a foreign name in katakana. File the version your target customers will naturally use. Your attorney can advise on the most common rendering
Assuming similarity protects you — A very similar katakana mark may not automatically block a competing registration. The JPO applies specific similarity criteria — consult your attorney on the risk level
Forgetting to search the katakana version — Always search both English and katakana versions before filing. An existing katakana registration can block your application even if no English version exists

FAQ

Does my English trademark protect the katakana version in Japan?

No. In Japan, an English trademark registration and a katakana trademark registration are treated as completely separate marks. Your English registration provides no protection over the katakana version. You must file a separate application for the katakana mark.

Can someone else register the katakana version of my brand in Japan?

Yes. Japan's first-to-file system means anyone can register the katakana transliteration of your brand name if you have not done so first. This is one of the most common forms of trademark squatting targeting foreign brands in Japan.

How do I know which katakana version to register?

Your Japanese trademark attorney will advise on the most natural and commonly used katakana rendering of your brand name. In some cases, multiple katakana versions exist — filing the most common one provides the strongest protection.

Should I also register a kanji version of my brand in Japan?

For most foreign brands, katakana is sufficient and more important than kanji. However, if your brand has an established Japanese-language meaning or translation used in your marketing, registering the kanji version as well may provide additional protection. Discuss this with your attorney.

Conclusion

Japan trademark katakana registration is not optional — it is essential. Your English mark and katakana mark are treated as completely separate trademarks in Japan. File both from day one.
