Internal Auditing

Group Internal Auditing

We believe that the role of internal auditing is extremely important if we are to “live up to customers’ expectations” and “implement transparent management” as set forth in the Resona Group’s Corporate Mission. Accordingly, we have established internal audit divisions at Resona Holdings and at main Group companies.

In order to ensure sound and appropriate operations and to gain social trust in the business management systems established by the Company and Group companies, the internal audit divisions serve the essential function of facilitating improvements in corporate value by verifying and evaluating the systems from an independent standpoint and promoting improvements as needed in all management activities.

The Company’s Internal Audit Division has introduced auditing methods in conformity with the Institute of Internal Auditors (IIA),* a leading international association in the field of internal audits, thereby practicing risk-based audits and ensuring that its peers at Group companies follow suit. In addition, the division monitors the activities of internal audit divisions at such companies while striving to improve the quality of internal audits by, for example, providing various information and training and supporting employees seeking qualification as certified internal auditors and/or to acquire other audit-related certification.

  • *An organization that formulates professional standards for internal auditors, engages in the research of theories and practices associated with internal auditing and promotes other activities aimed at providing leadership for the global profession of internal auditing.


The Company and Group companies have established independent internal audit divisions and other bodies under each board of directors.

Moreover, we have formed the Internal Audit Council, separate from the Executive Committee, to serve the Company and Group companies by discussing important matters related to internal auditing.

The Internal Audit Division of the Company reports to the Board of Directors and the Audit Committee for its functions and to the representative executive officers for its administration. In addition, by ensuring a direct reporting line from the Audit Committee to the Internal Audit Division, we strengthen the monitoring and check and balance functions the Company exerts over the representative executive officers and representative directors of the Group companies.
