Consult body to Executive Committee

The purpose of this framework is to respond comprehensively and quickly to potential risks that could affect management, risks (manifest risks) such as compliance violations, and crises (serious crises), in order to prevent them and reduce their impact. Under this framework, we have established Compliance Subcommittee and Risk Management Subcommittee, which work to raise employee awareness of compliance, deal with violations, anticipate and prevent risks, and respond to crises. - Sustainability Committee

This committee will work to develop systems and workplace environments that enable employees to grow more than ever before, while formulating human resource strategies aligned with management and business strategies to strengthen implementation. - Investment and Financing Committee
The purpose of the committee is to consider from various angles the implementation and follow-up of investments, loans, and corporate alliances, as well as the identification and revitalization of unprofitable businesses, in order to contribute to the deliberations of Executive Committee.
