Japan — Cyber Threat Profile
Japan has transitioned to a policy of "Active Cyber Defense," allowing for proactive neutralization of threats to national security. The National Center of Incident Readiness and Strategy (NISC) coordinates with the Digital Agency to secure the national supply chain, specifically targeting semiconductor manufacturing and energy grids. Japan is a key leader in "Quad" cybersecurity initiatives, focusing on shared standards for critical and emerging technologies. Domestic priorities include the integration of AI into defense systems to counter sophisticated state-sponsored attacks and protecting an aging population from complex digital financial scams. Japan's strategy reflects a heightened focus on economic security and regional stability.- National CERT/CSIRT: JPCERT/CC
