Protecting Intellectual Property in Japan

Japan has a robust legal framework to protect various forms of intellectual property. To safeguard your IP in Japan, it’s essential to understand the different categories:


Protect inventions and technological innovations. Japan operates under a “first-to-file” system, where the first person or entity to file a patent application is granted the rights.


Protect brands, logos, and symbols that distinguish goods or services. Registering a trademark in Japan grants exclusive rights and protection.


Protect original creative works, including literature, art, music, and software. Copyright protection is automatic upon creation, but registration can provide additional benefits.

Trade Secrets:

Protect confidential business information, formulas, processes, or practices that offer a competitive advantage.

Steps to Protect Your IP in Japan

Conduct Thorough Research

Before applying for protection, conduct extensive research to ensure your IP doesn’t infringe on existing rights. Check Japan’s IP databases and consult with legal experts to verify the uniqueness of your creation.

File for Protection

Patents: File a patent application with the Japan Patent Office (JPO). Consider working with a patent attorney for a smoother process.

Trademarks: Submit a trademark application to the Japan Patent Office or utilise the Madrid System for international protection.

Copyrights: While copyright protection is automatic, consider registering your work with the Agency for Cultural Affairs for additional benefits.

Keep Detailed Records

Maintain thorough documentation of the creation process, development, and any relevant dates. These records can serve as evidence of ownership in case of disputes.

Monitor and Enforce Rights

Regularly monitor your IP for any potential infringements. Act swiftly against unauthorized use by sending cease-and-desist letters or taking legal action if necessary.

Consider International Protection

If expanding globally, consider international treaties and agreements like the WIPO (World Intellectual Property Organization) to protect your IP in multiple countries, including Japan.

Challenges and Tips

Language and Cultural Barriers

Navigating Japan’s IP laws might be challenging due to language barriers and cultural differences. Engage local experts or attorneys who understand both the legal landscape and the nuances of conducting business in Japan.


Enforcing IP rights in Japan can be complex. Collaborate with legal professionals well-versed in Japanese IP law to effectively enforce your rights and protect against infringement.

Education and Training

Educate your team about the importance of IP protection. Implement robust internal policies and training sessions to ensure everyone understands the significance of safeguarding intellectual property.


Protecting your intellectual property in Japan demands diligence, strategic planning, and a comprehensive understanding of local laws. By proactively registering, monitoring, and enforcing your rights, you can safeguard your innovations and creative works, ensuring they remain valuable assets in the competitive market.

Remember, seeking guidance from legal experts with expertise in Japanese IP law is key to navigating the intricacies of protecting your intellectual property effectively.

Japan is Well Known as a Market that Respects Intellectual Property

One of the considerations companies must face is whether they have sufficient protection of their brand name and logo before attempting to enter overseas markets and launch their product or service there.

If you have built up significant value in your brand name or logo within your domestic market, it may be worth evaluating the benefits of registering them as a trademark.

Securing Intellectual Property Rights Can Help Build Awareness of Your Brand in Japan

Having the correct trademark and patent protection in place opens up possibilities of different revenue streams that come with brand licensing and potential limited edition collaborations with well-loved and established Japanese brands and companies.

For example, Peter Rabbit characters are often used for limited edition collectors’ items by the Japanese convenience store franchise chain Lawson, and popular theme park Fuji-Q Highland boasts a Thomas Land section, where visitors can enjoy Thomas the Tank Engine themed rides and attractions.

In order to register a trademark in Japan, you first need to have the trademark registered in the UK.

However, an international trademark application can be submitted while a UK trademark application is in progress.

It is important to note that the international trade mark application will be linked to the domestic registration. This means that if your UK trademark registration is allowed to lapse due to lack of use for example, then the international registration will also end. Similarly, the international trademark must be identical to your UK trademark.

Next Steps for Registering Your IP in Japan

There is an international system of trademark classification which allocates trademarks to a specific class of goods and services. There are 45 different classes of goods and services. A list of these classes can be found at

The Japan Patent Office website may also be a good point of call for information about intellectual property rights in Japan. Their section on Obtaining IP Rights contains extensive material on applying for patent and trademark protection.
