TOKYO, Japan, November 11, 2026, Japan has announced an emergency cybersecurity package worth approximately ¥10 billion, or US$63 million, following a series of cyberattacks that affected businesses and government agencies across the country. The initiative is intended to strengthen national cyber resilience, improve coordination between public and private organisations and accelerate assistance to companies dealing with security incidents.
Prime Minister Sanae Takaichi called for stronger preparedness and faster responses to cyber threats, including attacks that use artificial intelligence. The announcement follows a series of incidents that exposed customer information and disrupted business and public services.
The package reflects growing concern among governments about the potential impact of increasingly sophisticated cyberattacks on essential services, corporate operations and national security.
Four pillars of the emergency response
The Japanese government has outlined four main priorities for its emergency cybersecurity measures. These include improving basic security practices through greater use of technology, strengthening information gathering and investigative capabilities, improving responses to cyberattacks and expanding support for organisations affected by incidents.
The government also plans to strengthen its ability to identify and investigate infrastructure used by attackers. The measures build on Japan’s active cyber defence framework, which was legalised in October and expands the government’s capacity to respond to certain cyber threats.
For national security related incidents, officials from the Defense Ministry, National Police Agency and National Cybersecurity Office are expected to work together through a dedicated support structure.
Specialist teams to use AI in cyber defence
Japan’s Ministry of Economy, Trade and Industry is expected to establish a specialist team by the end of November. The team will use AI tools to identify network vulnerabilities and support efforts to counter cyber threats.
The initiative will involve cooperation with technology companies and AI developers in countries considered friendly to Japan. The use of AI is intended to improve the speed at which organisations identify weaknesses and assess potential threats.
The government also plans to establish a cyber rescue team involving public and private sector experts. This group will provide initial assistance to organisations affected by attacks, while another team will help vulnerable businesses strengthen their security arrangements.
Growing pressure on businesses and public institutions
The emergency package follows cyber incidents that have affected dozens of Japanese companies and government organisations. Such attacks can expose customer information, interrupt operations and create financial and reputational consequences for affected organisations.
Smaller businesses can be particularly vulnerable because they may lack dedicated security teams and the resources required to respond to complex incidents. Government support and coordinated technical assistance can therefore play an important role in improving preparedness across the wider economy.
Japan’s latest measures show that cybersecurity is increasingly being treated as a national resilience issue rather than solely an information technology responsibility. Their effectiveness will depend on implementation, cooperation with industry and the ability to provide practical support before and after security incidents.
