Internal Control


The Sumitomo Corporation Group has strengthened its internal controls to retain the trust of all its stakeholders.

Basic Policy and System

To realize sustainable growth and development, the Sumitomo Corporation Group is working on enhancing group governance and improving the overall quality of groupwide operations through the development, operation, evaluation, and improvement of appropriate internal controls. We have established basic regulations on internal controls to reasonably ensure compliance with laws and regulations related to business activities, safeguarding of assets against loss, effectiveness and efficiency of operations, and reliability of financial reporting in the Group’s overall businesses.

To ensure efficient operation of existing internal control frameworks, create synergy, and coordinate with internal audit functions, the Internal Control Promotion Department, which takes on overall control of the Group’s internal control-related operations, has been established alongside the Internal Auditing Department under the supervision of the Head of Internal Control and Internal Audit. By actively identifying issues and utilizing internal control activities within the Group, the department will promote greater effectiveness and consistency of the above efforts throughout the Group.

As of December 2, 2022

Financial Reporting

The Sumitomo Corporation Group creates financial reports in accordance with the Accounting Policy Manual that lays out the Group’s internal policies for accounting, and discloses information in a timely and appropriate manner and in compliance with relevant laws, regulations, and accounting standards.

For its financial reporting internal control system, the Company acts in accordance with the Internal Control Reporting System stipulated in the Financial Instruments and Exchange Act, by promoting internal control activities as required by the Act, and evaluating and improving its business processes.

Information Security

Led by the IT Strategy Committee, which is a companywide organization chaired by the Chief Information Officer (CIO), Sumitomo Corporation has established an Information Security Policy and other relevant regulations, and works to ensure information security and the appropriate management of information assets. For personal information,
we operates Privacy Policy and have put in place relevant regulations and organizational structures to ensure appropriate protection.

We also take steps to minimize the risk from unexpected situations involving information security, such as external attacks aimed for instance at theft or destruction of corporate information. In addition to system-based safeguards, these include continuous training and drills for officers and employees and system monitoring and upgrades covering our major subsidiaries and other group entities.

Internal Audits

The Internal Auditing Department is an independent organization under the supervision of the Head of Internal Control and Internal Audit, which reports directly to the President and Chief Executive Officer, that monitors the operations of the Group, and audits organizations and operating companies of the Group. As well as reporting the internal audit results directly to the President and Chief Executive Officer, in principle on a monthly basis, periodic reports are also made to the Board of Directors and the Audit & Supervisory Board. The department regularly conducts audits on all aspects of internal control, comprising asset and risk management, compliance, and business operations. It evaluates the effectiveness and adequacy of the internal controls of auditees, taking into account the significance of the inherent risks. At the same time, it provides appropriate advice for improvements and expedites improvement and maintenance on the auditee’s own initiative, thereby contributing to the improvement of governance and internal controls within the Group.

Group Governance

The Sumitomo Corporation Group consists of 886 companies in 78 countries and regions. These companies are the source of the Group’s strength. Their business domains fall under a wide range of industrial fields, and many of them are industry leaders.

The group companies respect the Sumitomo Corporation Group’s Corporate Mission Statement and management strategies, and engage in Jiritsu* management. Our approach to group management is to contribute to important decision-making at Board and other meetings through active dialogue based on relationships of trust as a shareholder, and to create new value through collaboration among group companies including Sumitomo Corporation. For the purpose of sharing and better implementing this basic approach and policies within the Group, we established the Group Management Policy (GMP) in 2021.

The GMP clarifies the roles and responsibilities in group management, setting forth the three principles of Jiritsu, dialogue, and collaboration to be respected by Sumitomo Corporation and its group companies.

The values set forth in the Sumitomo Corporation Group’s Corporate Mission Statement and the GMP are shared and implemented within the Group. This allows us to swiftly and appropriately respond to industry structural transformation and trends surrounding sustainability and to grow our group companies into future earning pillars, thereby further solidifying the Group’s business portfolio and maximizing corporate value.

  • Jiritsu is a Japanese term. In the GMP, we define it to mean “following the rules necessary for the management of a Sumitomo Corporation Group company, such as the Sumitomo Corporation Group’s management principles, strategies, and policies, to discipline oneself, to think, make decisions, act for oneself in order to achieve goals, and to be accountable to stakeholders.”
