| Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | HMC and its consolidated subsidiaries, including AHFC and HCFI (Honda), have established a management system and standards for information system security in order to minimize the negative impact on its business and business results from the occurrence of cybersecurity incidents. Based on these standards, Honda has implemented security measures in both hardware and software aspects to strengthen the security of its information systems. To address security, including product security, Honda has established a cross-functional system across business and manufacturing systems, software, quality, and other areas. Honda develops rules and procedures based on laws and regulations, formulates response flows, verifies and implements measures for improvement through cybersecurity exercises, and develops human resources, among other things. Honda also utilizes solutions for managing cybersecurity information and monitoring malicious activities to monitor and analyze cybersecurity threats and vulnerabilities, and in the event of a security incident related to a cyberattack with a significant impact on Honda, a Global Emergency Headquarters will be established under the supervision and monitoring of Honda's Risk Management Officer, and the supervisory division in charge of risks from cybersecurity threats plays a central role in quickly ascertaining the actual situation and taking measures to minimize the impacts of cybersecurity incidents from a company-wide perspective. When implementing third-party packaged software and cloud services, Honda makes decisions based on risk assessments following established security standards and conducts annual checks after implementation. In response to cyberattacks on production facilities and suppliers, Honda verifies the status of security measures at both domestic and overseas production facilities and suppliers. Based on the results of these verifications, Honda takes measures to strengthen security, such as supporting the introduction of solutions for managing cybersecurity incident information, and monitoring malicious activities. For such activities to strengthen security, Honda has concluded outsourcing agreements with security consulting companies and external specialists to receive support. With regard to personal information protection regulations and cybersecurity-related laws and regulations in various countries, in addition to current regulations, Honda collects and monitors information on regulatory trends that are expected to be enforced in the future. Data security incident response plans have been established at AHFC and HCFI that guide the analytical processes, response phases, and procedures to follow during a data security incident of personally identifiable information.
