Internal Control System

The internal control system of the Kubota Group is a mechanism for clearly providing the rules that should be followed during the performance of business, and for checking whether or not business has been managed according to those rules. This system consists of the segments of business management, which entails the performance of business operations based on rules, and risk management, which entails the management of major risks in management.
In business management, basic matters necessary for operating businesses are determined in business rules, and each business division checks its daily business operations in accordance with the business rules. Business rules comprise common business rules (basic rules) and functional business rules.
In risk management, operations that each department in charge of risk management should implement are determined in the risk management rules. Based on these rules, necessary actions to be promoted for risk management are identified and the departments are audited, thereby verifying the effectiveness of the risk management.
In the internal control system, major risks in Kubota’s management are classified into the following three categories:

  1. Internal control over reliability of financial reporting
  2. Internal control over the basic functions of the company, such as fair trade, environmental conservation, and health and safety
  3. Internal control over compliance, such as compliance with rules and regulations related to equipment, and import and export control

To avoid these risks, each department in charge implements necessary actions to be promoted and conducts audits of the relevant operational division, and reports the results and the measures for the next fiscal year to the President and the Board of Directors. Thus the PDCA cycle for risk management is implemented properly.

Kubota Group Risk Management Committee

In view of the changing public expectations regarding corporate risk management, we established the Kubota Group Risk Management Committee in January 2023 to adapt to these changes and to put in place a system able to respond flexibly to future changes.
With the aim of increasing the Kubota Group’s corporate value, the committee’s role is to maintain existing risk management activities relating to internal control risk and to put in place a new management system for risk with potential major impact on business operations.
To do this, the committee will undertake regular risk assessments of the Kubota Group in order to identify risks to be addressed as a priority. It is envisaged that subcommittees under the supervision of the Risk Management Committee will implement the risk response measures adopted and report back to the committee on their progress, which the committee will review before issuing instructions where necessary.
The director in charge of risk management will make regular reports to the Board of Directors on these risk assessments as well as on the associated response measures and policies and progress with their implementation.

Internal Control System Operation Activities (Risk Management Activities)

Kubota positions risk management activities as part of its business activities. Based on the awareness that risk management is the foundation of business activities, Kubota identifies risks common to the entire Kubota Group, such as those relating to the reliability of financial reporting, and exerts efforts to manage risks appropriately through continuous steady improvement to “immediately correct any inadequacies.” At the same time, while accelerating the global development of its businesses, Kubota strongly recognizes that risk management activities are the foundation for the continuity of its businesses, and strives to improve such activities both in Japan and overseas.

Kubota Hotline (whistleblowing system)

As a framework to support risk management, Kubota operates a whistleblowing system. This system aims to prevent, or quickly detect and correct, any illegal or unethical acts as well as to develop an open corporate culture.

[Types of contact points and matters handled]

  • Corporate Compliance Department: Compliance issues other than human rights (anonymous reporting acceptable)
  • Human Rights Advancement Department: Issues of human rights (anonymous reporting acceptable)
  • Outside lawyers: Compliance in general including human rights issues
  • Human Rights Advancement Consultation Office has been established at each company and business site so that people can more easily seek consultation.
  • Starting from 2017, consultation by e-mail, in addition to telephone, is acceptable for outside lawyers.

[Available to]

  • Full-time, part-time and temporary employees of Kubota and its Group companies in Japan
  • Each overseas location handles reporting individually and notifies the Kubota head office of any significant issues.
  • Starting from 2017, all whistleblowing cases in China are reported to the Kubota head office.

[Protection of informants]

The Whistleblowing System Operation Rules clearly state:

  • “the informer shall not be disadvantaged as a result of reporting an issue.”
  • “excluding cases necessarily requiring investigations and official reporting, the content of the reported issue, personal information obtained during investigations, and all other information shall not be used or disclosed.”

[Activities to raise awareness of the system]

Various creative ways have been employed to alleviate unease about the system, which is often the result of a lack of understanding.
The Company newsletter and website provide information on:

  • The number of reports received for each content category, and past cases (outline)
  • The flow of processes for using the Hotline
  • The objective of the system, protection of informants, handling of anonymity, etc.

[Number of cases reported (in Japan)]

  • Jan.–Dec., 2016 30 cases
  • Jan.–Dec., 2017 52 cases
  • Jan.–Dec., 2018 71 cases
  • Jan.–Dec., 2019 59 cases
  • Jan.–Dec., 2020 74 cases
  • Including enquiries and matters that were found not to be problematic as a result of investigation


Moreover, we have set up a space to write free comments in the Kubota Group Employee CSR Awareness Survey, which is answered in anonymity. It is an opportunity for employees to give their frank reports and opinions, enabling the Company to develop an open corporate culture.

Securing Reliability of Financial Reporting

Kubota has established and operates an internal control system in order to confirm the reliability of financial reporting for the entire Kubota Group, including its overseas subsidiaries.
Also to confirm the effectiveness of the system, the Corporate Auditing Department and the auditing divisions of the subsidiaries conduct regular internal audits.
Kubota has also created a system for evaluating the effectiveness of internal controls on a Group consolidated basis. This assessment is based on the results of the abovementioned auditing results, and conforms to the internal control reporting system related to financial reporting stipulated by the Finance Instruments and Exchange Act (J-SOX) and other ordinances.

Compliance with the Anti-Monopoly Act/Competition Law

We realize that full implementation of compliance is key to establishing Kubota as a Global Major Brand. The Kubota Group therefore engages in the risk management activities set out below to ensure advance preventive action against any infringement of antimonopoly or competition law.

Education and Enlightenment Activities

Kubota continuously offers training programs on the Anti-Monopoly Act/Competition Law at its business divisions as well as its Group companies both in Japan and overseas, for enlightenment and awareness-raising to ensure compliance. Legal training programs, which cover a broad range of legal matters including competition laws, are also provided for employees who are to be dispatched to overseas Group companies as managers.

Auditing and Risk Management Surveys

Kubota continuously conducts audits under the Anti-Monopoly Act, including on-site inspection, targeting Kubota and its Group companies in Japan. For overseas Group companies, Kubota conducts written audits, on-site interviews, and opinion exchange meetings, through which it determines the status of risk management.

Maintaining and Expanding the Consultation System

Kubota shares information with the relevant business departments and Group companies on matters related to business activities of Kubota and its Group companies that require examination under the Anti-Monopoly Act, and implements necessary measures including facilitating advance consultation with lawyers and other external experts.

Compliance with the Act against Delay in Payment to Subcontractors

Kubota conducts written surveys targeting each of its business divisions and Group companies in Japan on a periodic basis. Kubota also offers training programs to promote understanding of the Act against Delay in Payment to Subcontractors at each business site and Group company and holds consultancy sessions concerning practical operations, such as ordering, related to the Subcontractors Act, thereby developing voluntary risk management systems.

Prevention of Illegal Payments

Kubota Group has placed particular focus on preventing bribery among risk management activities on the preventing illegal payment, and will work to achieve SDGs Target 16.5: Substantially reduce corruption and bribery in all their forms.
Amid increasing international moves to anti-bribery, we marked December 9 – designated by the United Nations as International Anti-Corruption Day – by broadcasting a President’s Message to all Kubota Group officers and employees every year. In the message, our top management made a clear commitment by declaring that ‘Kubota Group rejects bribery and all other inappropriate business practices.’ As a focused initiative to educate officers and employees on prevention of bribery, Kubota Group runs a program of training sessions in Japan and overseas. In FY2020, under coronavirus pandemic, new approach were taken such as web-based training sessions and an e-learning program to prevent further spread of infection. In the web-based training, information on bribery-related legislation and enforcement conditions in each country is presented as well as the case studies of bribery. And the e-learning was prepared to have an impact to the viewers by introducing a message movie from the President of Kubota Corporation at the beginning, as well as adopting movies and comprehension test in the program. Through continuous program of training sessions, Kubota Group seek to disseminate the latest information and to promote awareness of bribery prevention.
Additionally, we have put together a Kubota Group Handbook for Anti-Bribery which outlines our Anti-Bribery Policy and the main points of our Anti-Bribery Guidelines. The Handbook is issued in a global version with universal content available in Japanese, English and French, and in individual country versions that supplement the universal content with more detailed information on the points to be noted and actions to be taken in the particular country or region. These are available for China, Thailand, Korea, Indonesia, Myanmar, the Philippines, Vietnam and Mexico.
Meanwhile, as an initiative directed toward outside the company, ‘Request to Suppliers’ was posted on the Kubota website in the name of the General Manager of the Corporate Compliance and Risk Management Headquarters. The text outlined to suppliers the Kubota Group’s approach to bribery prevention and asked for their understanding and cooperation in bribery prevention activities.
To verify these risk management activities, Kubota Group has established the Committee on Prevention of Illegal Payments. In FY2020, document surveys were conducted at 11 departments/companies in Japan and 39 overseas bases to investigate whether preventive framework were in place and sufficiently functioning, as well as whether there were any illegal payments.
The policies for these risk management activities and the results of the activities are periodically reported to the President, the Board of Directors, and the Audits & Supervisory Board through the Company-wide Risk Management Committee, composed mainly Directors, and based on their feedback, the contents of activities are occasionally revised thereby improving the level of the activities.
