Reclaiming a squatted mark is expensive, slow, and not guaranteed

Japan trademark squatting is a real and growing risk for foreign businesses. Squatters file registrations for well-known foreign brands ahead of the legitimate owners — then demand payment to transfer or simply block market entry.

File before a squatter does.

What is Japan Trademark Squatting

Trademark squatting occurs when a third party — with no legitimate connection to a brand — files a trademark application in Japan using another company's brand name, logo, or mark.

Japan's first-to-file system makes this possible. The squatter files before the legitimate owner and gains legal rights.

Common squatting scenarios:

A squatter registers a foreign brand name in Japan — then demands a large payment for the transfer
A former distributor or business partner registers the brand independently after the relationship ends
A competitor files a similar mark to block market entry
A squatter registers the katakana transliteration of a foreign brand while the foreign company only holds the English version

Japan Trademark Cost: Prevention vs Recovery

Action	Estimated cost
File now (1 class, 10-year) — prevention	¥44,900 JPO fees + ¥50,000 attorney fees (¥25,000 at filing + ¥25,000 at registration, excl. tax)
Invalidation trial to cancel squatted mark	Quote on request
Civil litigation against squatter	Quote on request
Negotiated buyback from squatter	Unpredictable

Filing now costs a fraction of recovering a squatted mark. Prevention is the only reliable strategy.

Trademark Filing Process: How to Protect Against Squatting

Search immediately — Check J-PlatPat now for existing filings of your brand name in Japanese and English. BrandAgent provides this free
File before going public — File your Japan trademark application before any press releases, product launches, or public announcements about the Japanese market
Register both English and katakana — Squatters often target the katakana version of foreign brands. Register both from the start
Cover all relevant classes — A squatter can register your mark in a class you did not cover. File in all classes you actively use or plan to use
Monitor the JPO register — Set up ongoing watch services to be alerted when similar marks are filed by others after your registration
Act quickly on discovered squatting — If a squatter has already filed, consult a Japanese trademark attorney immediately. Time-sensitive options include opposition (2-month window) or invalidation proceedings

Common Mistakes

Filing after launching in Japan — Any public announcement gives squatters advance notice. File before you announce anything
English only registration — The katakana version is just as important. Squatters specifically target unregistered katakana versions of foreign brands
Assuming overseas registration protects you in Japan — A US, EU, or UK trademark gives you no rights in Japan. Japan requires a separate local registration
Delaying action after discovery — If a squatter has filed but not yet been published, act immediately. Once published, you have only 2 months to oppose
Trying to negotiate without legal support — Squatters understand the leverage they hold. Always work through a Japanese trademark attorney in any buyback or transfer negotiation

FAQ

Can I cancel a squatted trademark in Japan?

Possibly — but it is difficult and expensive. If the squatted mark was filed in bad faith and conflicts with your well-known brand, an invalidation trial may succeed. However, outcomes are not guaranteed and proceedings take 1–2 years. Prevention through early filing is far more reliable.

Does Japan recognise bad faith trademark filing?

Yes. Japan's Trademark Act includes provisions against marks filed in bad faith. If a squatter clearly targeted a well-known foreign brand with no legitimate purpose, an invalidation trial on bad faith grounds may succeed — but requires substantial evidence and legal argument.

My brand has been squatted in Japan — what should I do?

Contact a Japanese trademark attorney immediately. Time-sensitive options depend on where the squatter's application is in the process. If still pending or recently published, opposition or invalidation may be possible. Your attorney will assess the fastest and most cost-effective path forward.

How quickly can BrandAgent file a protective trademark application?

BrandAgent can typically prepare and file a trademark application within 1–2 weeks of receiving instructions. For urgent cases, faster filing may be possible. Contact us to discuss your timeline.

Conclusion

Japan trademark squatting is preventable — but only if you act before the squatter does. File your Japan trademark application before you announce your brand publicly in Japan.
