Japan’s ruling Liberal Democratic Party proposed a new Cyber Response Headquarters led by the Prime Minister’s Office to coordinate ministry responses, citing recurring personal-data leaks and divided responsibilities among ministries.
The Prime Minister’s Office said Prime Minister Sanae Takaichi received the proposal on Oct. 23. The LDP wants the headquarters to be led by the Prime Minister’s Office and to coordinate responses across ministries. Its recommendations also call for greater cybersecurity awareness among corporate executives and for developing and securing cybersecurity personnel. The headquarters remains a proposal; the handover did not establish it.
The LDP said recurring leaks of personal information from private companies have raised public concern. It described divided responsibilities among ministries as a coordination problem and warned that artificial intelligence could enable saturation attacks — efforts to overwhelm systems. The party’s recommendations combine a central government structure with measures aimed at corporate preparedness and the cybersecurity workforce.
Japan’s National Cybersecurity Office (NCO) said unauthorized access had exposed personal information at organizations in multiple sectors, in an Oct. 14 notice. People whose information was exposed and the companies that held it are directly affected by the leaks cited by the LDP.
Trend Micro counted 607 publicly disclosed cybersecurity incidents in Japan from January through September, compared with 594 for all of 2025. The 2026 count covered nine months and was 13 higher than the prior year’s full-year figure. The company said its tally, based on reports as of Oct. 9, could be revised. EconoTimes previously reported Trend Micro’s tally of Japanese cybersecurity incidents.
The proposal places coordination within government alongside recommendations for businesses to prepare executives and develop cybersecurity staffing. The LDP linked the plan to public concern over data leaks, while the NCO’s notice described exposure across multiple sectors. Together, the recommendations address response across ministries and readiness within organizations.
