Japan's government plans to adopt a 'Cybersecurity Emergency Measures Package' at a cybersecurity ministerial meeting on 6 November, with the outline becoming known on the 5th. Its centrepiece is a new '(provisional) public-private cyber rescue team' dispatched flexibly to victim organisations, structured around four pillars: thorough basic measures, stronger intelligence and investigation, strategic use of active cyber defence, and victim support. It foregrounds the view that advancing AI now lets defensive gaps be exploited quickly and at scale.
The rescue team and a joint response team
The draft sets up a team of public and private specialists, dispatched to back up the initial response when a victim organisation requests support and urgency is high. Its secretariat is to be placed in the National Cyber Office within the fiscal year, and for serious incidents a '(provisional) joint response team' of the office, the responsible ministries, police and the Defense Ministry and Self-Defense Forces is sent. Chief Cabinet Secretary Minoru Kihara said on the 5th he wanted it to be a starting point for a society with world-class cyber resilience.
The government also plans to spend about 10 billion yen from this fiscal year's reserve fund, reportedly for costs including police system development. The package gives concrete form to the emergency measures Prime Minister Takaichi ordered on 26 October, against a run of data leaks from unauthorised access, so the 6 November decision turns that political instruction into funding and an implementing structure.
AI-centred inspection and ties to frontier-AI firms
The first pillar stands up a 'top-gun talent team' of advanced specialists within the month to probe public and private defences with AI-driven simulated attacks. The second deepens cooperation with frontier-AI firms, aiming to obtain unpublished vulnerability information early. The package thus treats AI as a threat and, at the same time, as a tool for inspection and intelligence gathering.
The outline shows the direction of the framework; the team's size, the budget breakdown and the criteria for dispatch are not yet public. How active cyber defence, which entered full operation on 1 October, will be applied in serious incidents is still being worked out.
