Japan eyes using cutting-edge AI under preemptive cyber defense policy

Japan is considering the integration of advanced AI systems into its cyber defense strategy to counter sophisticated threats. Officials emphasize the need for automation in vulnerability detection while maintaining human oversight.
Why it matters
The use of AI in national security raises critical questions about the speed of cyber warfare and the necessity of human-in-the-loop decision-making.
TOKYO - Japan is considering utilizing cutting-edge artificial intelligence systems under its preemptive cyber defense policy in the face of the risk of attacks by advanced models such as U.S. startup Anthropic's Claude Mythos, a senior government official said.
Amid growing concerns over cyberattacks by AI models with high capabilities to detect security vulnerabilities, it is "inevitable" that Japan will use sophisticated AI technology, said National Cyber Director Yoichi Iida.
"It would be no surprise if the time between vulnerability discovery and exploitation were shortened to a fraction of a hundredth or a thousandth of what it used to be," Iida said in a recent interview with Kyodo News.
