Category: Regulatory Update
Background & Context
The Japanese government has been increasingly vigilant about controlling substances that may pose a risk to public health, particularly those with psychoactive effects. The latest regulations, issued by Japan Customs (Nihon Zeikan), focus on items that are suspected to have similar or greater psychoactive potential than designated drugs. This move aligns with Japan’s commitment to international drug control treaties and reflects a broader trend towards stricter import regulations. The legal framework governing these substances includes the Narcotics and Psychotropics Control Act (Shin’yō Shōhō) and the Stimulants Control Act (Chōsokudō Shōhō), which have seen amendments over the years to adapt to emerging threats. The new regulations were officially published on May 18, 2023, marking a significant shift in how Japan approaches the importation of potentially dangerous goods. Businesses must now navigate these changes carefully to remain compliant and avoid penalties.How This Affects Your Business in Japan

1. Foreign Residents Already Operating a Business in Japan
If you are currently importing goods, it is crucial to review your inventory for any items that may fall under the new psychoactive regulations. You should conduct a thorough analysis of your products to ensure compliance with the Narcotics and Psychotropics Control Act. Failure to do so could result in confiscation of goods and legal penalties. It is advisable to consult with a legal expert specializing in Japanese import regulations to assess your risk and make necessary adjustments. Documentation required may include product specifications and supplier information.
2. Foreign Nationals Planning to Establish a New Company
For those looking to start a business that involves importing goods, understanding these regulations is vital. Before launching, conduct market research to identify any psychoactive substances that may be prevalent in your target market. Ensure that your business plan includes compliance strategies for the Narcotics and Psychotropics Control Act. You may need to prepare documentation such as import licenses and safety assessments. Engaging with a local legal advisor can help streamline this process and avoid costly mistakes.
3. Foreign Investors Who Are NOT Residents of Japan
If you are considering investing in Japanese companies that deal with imports, it is essential to evaluate their compliance with the new psychoactive substance regulations. Conduct due diligence to ensure that the companies you invest in are not at risk of violating these laws. This may involve reviewing their import practices and compliance history. Failure to consider these factors could lead to financial losses and reputational damage. It is advisable to seek guidance from legal experts familiar with Japanese import laws to mitigate risks effectively.
