Customs Intellectual Property Infringement Seizure Status in the First Half of Reiwa 8 (2026)

In the first half of 2026, Japan’s customs authorities reported a significant increase in the seizure of goods infringing intellectual property rights. This development is crucial for foreign entrepreneurs operating in Japan, as it highlights the importance of understanding and complying with local intellectual property regulations to avoid costly legal issues and ensure smooth business operations.

Background & Context

Japan has a robust legal framework for protecting intellectual property rights, governed by laws such as the Copyright Act (著作権法, Chosakuken-hō) and the Trademark Act (商標法, Shōhyō-hō). The Customs and Tariff Bureau of the Ministry of Finance (財務省関税局, Zaimu-shō Kanzei-kyoku) is responsible for enforcing these laws at the border. In recent years, Japan has strengthened its customs procedures to combat the influx of counterfeit goods, which not only harms legitimate businesses but also poses risks to consumers. The government has implemented various measures, including enhanced training for customs officers and improved cooperation with international organizations. The latest report indicates a marked increase in the number of seizures, reflecting the government’s commitment to protecting intellectual property. This trend is part of a broader strategy to enhance Japan’s trade environment and ensure fair competition. The timeline of regulatory changes includes the introduction of stricter penalties for infringement in 2021 and ongoing amendments to customs procedures aimed at improving efficiency and effectiveness in detecting counterfeit goods.

1. Foreign Residents Already Operating a Business in Japan
If you are currently running a business, it is essential to review your product lines for potential intellectual property issues. Ensure that all products comply with Japanese laws to avoid seizures. You may need to provide documentation proving the authenticity of your goods. Failure to comply could result in significant financial losses and damage to your reputation. It is advisable to consult with a legal expert specializing in intellectual property to ensure compliance.

2. Foreign Nationals Planning to Establish a New Company
For those looking to enter the Japanese market, understanding the intellectual property landscape is crucial. Before launching your business, conduct thorough research on existing trademarks and patents in your industry. Register your intellectual property rights early to protect your brand and products from potential infringement. This proactive approach can save you from legal disputes and enhance your market position.

3. Foreign Investors Who Are NOT Residents of Japan
If you are considering investing in Japanese companies, be aware of the intellectual property risks associated with your investments. Conduct due diligence on the companies you plan to invest in, focusing on their intellectual property compliance and history of infringements. Engaging with local legal counsel can help mitigate risks and ensure that your investment is secure. Ignoring these aspects could lead to financial losses and impact your overall investment strategy.
