Japan Tightens Data-Privacy Rules And Expands Cross-border Enforcement, Raising Compliance Risks

Although domestic enforcement volumes in Japan remain modest in some areas compared with overseas authorities, actions by foreign regulators against Japanese companies, together with ongoing domestic legislative and regulatory trends, continued to elevate enforcement risk for in-house counsel and sharpen compliance awareness across Japanese companies. 

Amendments to the Whistleblower Protection Act strengthened protections and raised expectations for effective internal reporting and response. Japan's Ministry of Economy, Trade and Industry (METI) reinforced export and import controls- related regulations and signaled stricter enforcement, further tightening export-control compliance requirements. Cybersecurity rose to the top of the agenda as cyberattacks caused market-moving disruptions, and the Active Cyber Defense law was enacted, highlighting the need for enhanced risk management and collaboration between business and government.
