Tokyo Faces Security Risks Amid US Export Controls
Japan’s National Cyber Director, Yoichi Iida, has warned that the US AI export ban has affected the country’s security vulnerability scanning operations, highlighting the risks of relying on US AI for critical security functions. The ban, which suspended access to Anthropic’s Fable 5 and Mythos 5 models, has disrupted Japan’s preparations for its Active Cyber Defense Act, which is set to take effect on October 1, 2026. The law authorizes preemptive action against hostile cyber infrastructure, but requires metadata analysis, not content, to protect communications secrecy.
