Background & Context

The Japanese Financial Services Agency (FSA) has released two significant documents aimed at enhancing cyber resilience within the financial sector. These documents, titled ‘Cyber Resilience Practical Toolset: Practical Considerations for FMIs’ and ‘Discussion Paper on Challenges and Risks of Third-Party Dependencies for Financial Market Infrastructures (FMIs),’ provide a comprehensive framework for addressing cyber risks. The FSA has been proactive in addressing cybersecurity issues, particularly following the increasing frequency and sophistication of cyberattacks globally. The legal framework surrounding this initiative includes the Financial Instruments and Exchange Act (Shōken Torihiki-hō) and the Payment Services Act (Shiharai Sābisu-hō), which emphasize the importance of risk management and operational resilience. The timeline of regulatory changes indicates a growing recognition of the need for robust cybersecurity measures, with the FSA continuously updating its guidelines to reflect international best practices. These efforts align with global standards set by organizations such as the Bank for International Settlements (BIS) and the International Organization of Securities Commissions (IOSCO).

1. Foreign Residents Already Operating a Business in Japan
For those already established, it is critical to review and enhance your cybersecurity measures in line with the FSA’s new guidelines. You should conduct a thorough risk assessment of your current systems, particularly focusing on third-party vendors. Documentation of your cybersecurity policies and incident response plans will be necessary for compliance. Failure to act could expose your business to increased risks of cyberattacks and potential regulatory penalties.

2. Foreign Nationals Planning to Establish a New Company
If you are considering starting a business in Japan, it is essential to integrate cybersecurity measures from the outset. This includes selecting reliable third-party service providers and ensuring they comply with the FSA’s guidelines. You will need to prepare a comprehensive business plan that includes your approach to cybersecurity, which may require legal consultation. Not addressing these issues early could hinder your business operations and lead to costly setbacks.

3. Foreign Investors Who Are NOT Residents of Japan
For investors looking to fund businesses in Japan, understanding the cybersecurity landscape is vital. You should assess the cybersecurity practices of potential investment targets to mitigate risks. Engaging with local legal and financial advisors can help you navigate these requirements. Ignoring cybersecurity due diligence could result in significant financial losses and damage to your investment portfolio.
