TOKYO, JAPAN — Japan is launching an emergency cybersecurity offensive after a wave of hacking incidents exposed customer information, disrupted businesses and raised serious questions about whether the country’s digital defences can keep pace with increasingly sophisticated cybercriminals.
Prime Minister Sanae Takaichi announced a sweeping package of countermeasures on Friday, November 6, allocating an initial ¥10 billion, approximately US$63 million, to strengthen security across government agencies and private companies.
The initiative includes artificial intelligence-powered vulnerability testing, specialist investigation teams and a proposed rapid-response network that could dispatch cybersecurity experts to organizations under attack.
But the announcement comes amid a troubling series of incidents involving some of Japan’s most recognizable businesses.
A major breach involving car-sharing operator Times Car reportedly exposed information associated with approximately 6.6 million member accounts, while companies including Lawson, Daiwa Securities and BookOff have also disclosed cybersecurity incidents.
And the situation could become more complicated as increasingly capable AI tools make certain aspects of cyberattacks faster and easier to automate.
The Japanese government now faces a critical challenge: strengthening digital security before another major incident exposes sensitive information or disrupts essential services.
Japan’s Prime Minister Orders an Emergency Cybersecurity Response
Takaichi unveiled the measures following a ministerial meeting on November 6.
The government had been working on the package since October 26, when the prime minister called for an urgent response to worsening cybersecurity threats.
The announcement followed reports of unauthorized access to corporate and government systems, along with incidents involving customer-data exposure.
Takaichi instructed ministries to coordinate their efforts and accelerate the implementation of countermeasures.
The government identified four broad priorities:
- Strengthening fundamental cybersecurity measures, including AI-assisted vulnerability testing.
- Improving threat intelligence, investigation and analysis.
- Expanding capabilities to respond strategically to cyberattacks.
- Supporting affected organizations while limiting further damage.
The initiative will initially use approximately ¥10 billion from fiscal 2026 reserve funds.
However, Takaichi acknowledged that the total cost of the broader programme could be higher.
She instructed relevant ministers to examine additional financing arrangements.
That distinction matters.
Japan has approved initial emergency funding, not a final ceiling on all cybersecurity spending.
Why Japan Is Building an Elite AI Cybersecurity Team
One of the package’s most important proposals is the creation of a specialist team of cybersecurity experts.
According to the Associated Press and The Japan Times, the Ministry of Economy, Trade and Industry intends to establish the team by the end of November.
The specialists, described in reporting as a “top gun” unit, will use advanced technologies to identify weaknesses in computer networks and strengthen defences.
Their work is expected to include controlled security assessments and the use of artificial intelligence to assist vulnerability detection.
The team will also cooperate with technology companies and AI developers in friendly countries.
The purpose is to obtain access to expertise and tools that can help Japanese organizations respond to rapidly changing digital threats.
But the initiative does not mean AI can automatically prevent every cybersecurity incident.
Security still depends on reliable monitoring, appropriate access controls, timely software updates and trained personnel.
AI can improve parts of the process, but it can also produce inaccurate results or overlook important vulnerabilities.
Human verification and effective security procedures will therefore remain essential.
Japan Plans Cyber Rescue Teams for Companies Under Attack
The emergency package also includes plans for a public-private cyber rescue team.
Rather than leaving every company to handle a serious breach alone, the government intends to establish arrangements for deploying experienced cybersecurity personnel to affected organizations.
The proposed team would help with early-stage incident response.
That could involve assessing the situation, supporting containment, preserving relevant evidence and advising on recovery.
A separate team is expected to assist organizations with weak security arrangements before attacks occur.
The government also plans to establish a secretariat during the current fiscal year to coordinate support when incidents require urgent intervention.
These measures recognize that many businesses lack large internal cybersecurity departments.
Small and medium-sized companies may have particularly limited resources.
An organization can be vulnerable even when it is not the primary target of a cybercriminal operation.
Attackers may exploit a smaller supplier or technology partner to reach information associated with larger businesses.
Japan’s strategy therefore emphasizes improving resilience across entire supply chains.
More Than 500 Cyberattacks Reported in Japan This Year
The scale of Japan’s cybersecurity problem has become increasingly apparent.
According to a study cited by the Associated Press and conducted by Yomiuri Shimbun and Trend Micro, more than 500 cyberattack cases had been recorded in 2026 by early October.
That compared with 473 cases in 2025 and 503 in 2024.
The numbers suggested that 2026 could exceed previous annual totals.
However, the figures require context.
They represent incidents counted under the study’s methodology, not every attempted intrusion against Japanese networks.
They also do not establish that every reported case caused a successful data breach.
Nevertheless, the trend has alarmed policymakers.
As more businesses rely on digital infrastructure, even a limited security failure can create consequences for customers, suppliers and other organizations.
The government is attempting to address both the frequency of incidents and their potential severity.
Times Car Breach Exposes Information From 6.6 Million Accounts
One of the most prominent cases involved Times Car, a major Japanese car-sharing service.
A cybersecurity incident reportedly exposed information associated with approximately 6.6 million member accounts.
The case drew attention because car-sharing companies hold information used to identify customers and administer vehicle rentals.
Such information can include personal identification and contact details.
A large-scale exposure creates risks even when the reporting does not establish that criminals have accessed customers’ financial accounts.
For example, stolen identification details could potentially make impersonation attempts more convincing.
But a potential risk is not proof that identity fraud has already occurred.
The Times Car incident demonstrates why companies must assess both the scale and sensitivity of information stored in their systems.
It also raises questions about whether organizations can detect unauthorized access quickly enough to minimize damage.
Lawson, Daiwa Securities and BookOff Also Report Breaches
The problems extend across multiple industries.
The Associated Press reported that Japanese convenience-store chain Lawson, financial services company Daiwa Securities and secondhand retailer BookOff were among the businesses that had disclosed customer-data breaches.
These companies operate in very different sectors.
But all depend on computer systems that manage valuable information.
A convenience-store chain may operate customer loyalty and payment-related services.
A securities company handles sensitive financial and account information.
A retailer may maintain extensive membership and transaction databases.
Cybersecurity failures in any of these environments can damage customer confidence.
They may also create financial and operational costs.
However, the incidents should not be described as one coordinated campaign without evidence linking the attackers.
The companies’ disclosures represent separate cybersecurity events unless investigators establish a connection.
Artificial Intelligence Is Changing the Hacking Threat
One of the biggest concerns behind Japan’s response is the growing use of artificial intelligence in cybersecurity.
AI can help security professionals analyze software, identify suspicious activity and examine system weaknesses.
But similar capabilities may be exploited by malicious actors.
Cybercriminals could use AI to accelerate certain stages of reconnaissance, vulnerability discovery or phishing.
That creates a difficult situation for defenders.
The same technology used to strengthen protection can also lower the time and expertise required for some attacks.
International law-enforcement organizations have warned about this development.
As WWC ONE MEDIA reported in its coverage of INTERPOL’s warning about agentic AI, increasingly autonomous AI systems could allow cybercriminals to scale aspects of their operations.
However, these capabilities do not make every AI-assisted attempt successful.
Attack outcomes still depend on the security of the target, the tools available and the actions taken by those responsible.
For Japan, the challenge is to use AI defensively without assuming that technology alone can eliminate cybercrime.
Japanese Security Researchers Identify AI Tool Used in Hacking Incidents
The original CNA report also cited findings involving an AI-assisted cybersecurity tool called Artex.
According to a security arm of Japan’s GMO Internet Group, the tool had been used in several recent hacking incidents targeting Japanese companies.
GMO Internet Group itself was among the organizations reporting cyber-related attacks.
The findings are important because legitimate security tools can sometimes be misused.
Software designed to identify vulnerabilities may assist defenders conducting authorized testing.
But similar functionality may be exploited by individuals attempting unauthorized access.
That does not establish that every user of such a tool is a criminal.
Nor does it prove that the developers intended it to support malicious activity.
The relevant issue is how the technology was used and whether the activity was authorized.
A separate cybersecurity investigation involving South Korean financial institutions illustrates the broader concern.
As WWC ONE MEDIA reported in its coverage of suspected AI-assisted bank hacking, researchers identified possible use of AI tools in an intrusion campaign.
The researchers had not definitively established the suspect’s identity.
The South Korean case is separate from Japan’s emergency package.
But it highlights why authorities across Asia are examining how advanced software tools may influence cybercrime.
Japan Wants Earlier Access to Software Vulnerability Information
Another major issue is the speed at which newly discovered vulnerabilities can be exploited.
Reuters reported on November 4 that Japan was considering asking US artificial intelligence developers and other foreign technology companies for advance information about serious software weaknesses.
The report followed concerns involving vulnerabilities in PHP, a widely used web programming language.
If important security weaknesses become publicly known before organizations install fixes, attackers may attempt to exploit vulnerable systems.
Earlier warning could give government agencies and critical infrastructure operators more time to prepare.
However, vulnerability-information sharing also requires careful controls.
Companies must consider how sensitive technical details are distributed and who receives them.
Japan’s proposed cooperation with foreign AI developers could become an important part of its wider cyber defence strategy.
But the Reuters report described plans under consideration, not a completed agreement with every relevant technology company.
Japan Expands Its Active Cyber Defence Capabilities
The emergency response also follows changes to Japan’s legal approach to cybersecurity.
Under its active cyber defence framework, authorities have gained additional powers intended to help identify and disrupt certain malicious activities before they cause serious damage.
The Associated Press reported that relevant provisions were legalized in October 2026.
The government is now considering additional measures to strengthen those capabilities.
Officials from the Defence Ministry, National Police Agency and National Cybersecurity Office may cooperate when an incident presents a significant national-security threat.
The approach reflects a change from relying solely on protecting individual networks.
Japan also wants to improve its ability to identify serious threats and respond before they spread.
However, these powers operate within legal and institutional constraints.
The announcement should not be interpreted as unrestricted permission for government agencies to access any system or conduct arbitrary cyber operations.
The precise scope of future measures will depend on applicable law, oversight and implementation rules.
Why Japan’s Cyber Crisis Matters to the Global Economy
Japan is one of the world’s largest economies and an important participant in international manufacturing.
Its businesses supply vehicles, electronics, industrial equipment and specialized components.
Many operate complex international networks of suppliers and customers.
A serious cybersecurity incident can affect more than the company initially targeted.
Manufacturing operations may experience disruptions.
Suppliers may face delays.
Customers may be unable to access digital services.
Financial and personal information could also become exposed.
The importance of supply-chain security means cybersecurity weaknesses can create economic risks that extend beyond national borders.
For businesses in Southeast Asia, including the Philippines, Japan’s response is worth watching.
Regional manufacturers and service providers that work with Japanese companies may face growing expectations for stronger security controls and faster incident reporting.
However, the November 6 package has not established new cybersecurity obligations for every overseas supplier.
Any such requirements would depend on future laws, contracts or industry standards.
Singapore’s Recent Cybersecurity Warnings Offer a Regional Comparison
Other Asian governments are also responding to the cybersecurity risks associated with AI.
Singapore recently reported no evidence that certain PHP software vulnerabilities had been exploited in its government or critical information infrastructure systems.
However, authorities urged companies to strengthen their defences.
As WWC ONE MEDIA reported in its November 4 coverage of Singapore’s PHP cybersecurity warning, officials emphasized the importance of vulnerability management and preventing attacks rather than waiting for serious damage.
Singapore’s warning was a separate national development.
It does not establish that the same attackers were responsible for incidents in Japan.
But the two countries face similar challenges.
Both operate highly digital economies.
Both rely on interconnected technology systems.
And both must prepare for threats that can spread quickly through vulnerable software and supplier networks.
AI-Powered Cyber Threats Are Becoming a Global Security Concern
The risks associated with artificial intelligence extend beyond Asia.
Britain’s National Cyber Security Centre has warned that AI could help make future ransomware attacks against critical infrastructure more effective.
As WWC ONE MEDIA reported in its coverage of the UK’s 2028 cyberattack warning, security officials are preparing for scenarios involving essential services such as electricity, transportation and manufacturing.
The warning is a forecast, not confirmation that a specific attack will occur in 2028.
Nevertheless, it reflects a wider concern among cybersecurity agencies.
Attackers may use advanced technology to identify weaknesses more quickly.
Defenders must therefore improve their own systems, skills and coordination.
Japan’s new emergency programme fits into that international effort.
It seeks to combine technology, personnel and government coordination rather than depend on any single solution.
Could Japan’s Cyber Rescue Teams Help Smaller Businesses?
Small and medium-sized companies could be among the most important beneficiaries of Japan’s new measures.
Large corporations may have dedicated cybersecurity departments and access to specialist consultants.
Smaller businesses often operate with limited technical staff and budgets.
That can make it harder to investigate a breach or respond to an attack.
A coordinated cyber rescue team could help businesses obtain assistance more quickly.
It might also reduce confusion about which authorities or specialists to contact.
However, the scheme’s effectiveness will depend on implementation.
The government must determine how teams are deployed, how cases are prioritized and what support can realistically be provided.
A rescue team may help contain an incident, but it cannot guarantee that stolen information will be recovered or that every affected business will resume operations immediately.
The objective is to improve response and recovery.
What Happens Next for Japan’s Cybersecurity Strategy?
Several developments will determine whether the November 6 announcement delivers meaningful results.
The first is the establishment of the government’s specialist AI cybersecurity team by the end of November.
The second is the creation of effective arrangements for deploying public-private cyber rescue specialists.
The third involves stronger cooperation with domestic and international technology companies.
The fourth is the development of better information-sharing systems across government agencies and critical industries.
Finally, the government must assess whether existing legal powers and cybersecurity practices are adequate.
Takaichi has instructed ministers to examine longer-term reforms alongside the immediate measures.
The emergency package therefore represents the beginning of a broader effort, not proof that Japan’s cybersecurity problems have already been resolved.
The Bottom Line: Japan Is Fighting Back Against a Rapidly Evolving Cyber Threat
Japan has approved an initial ¥10-billion emergency cybersecurity package after a series of serious hacking incidents affected major businesses and government organizations.
Prime Minister Sanae Takaichi announced the measures on November 6, emphasizing the need for stronger protection, faster investigations and better support for organizations suffering attacks.
The package includes AI-assisted security testing, an elite cybersecurity team and plans for public-private cyber rescue operations.
It also supports stronger coordination involving government agencies and industry experts.
The announcement comes after breaches affecting companies including Times Car, Lawson, Daiwa Securities and BookOff.
But the new programme faces difficult challenges.
Cyber threats are evolving rapidly.
Artificial intelligence may help both defenders and attackers.
And organizations must still address basic weaknesses involving software security, access controls and incident response.
As Japan commits billions of yen to building stronger digital defences, one question now hangs over its technology-driven economy: Can Takaichi’s new AI-powered cybersecurity strategy stop the next major attack before millions more records are exposed—or will cybercriminals find new weaknesses faster than the government can close them?
