Compliance
Policies and Basic Approach
The Taisei Group has established the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole as the basic principles of organizational behavior and standards of behavior and judgment that should be actively practiced or strictly observed by executives and employees. These Action Guidelines are the Group’s code of compliance. In the Fundamental Policy to Enhance Operational Compliance Systems, they state that “Members of the Board shall recognize that compliance is at the core of good management and shall faithfully comply with all compliance-related regulations, including the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole.” This is applied to all Group companies, including those in Japan and overseas.

Structures and Systems
Compliance Promotion System
As shown in the diagram below, the Company has appointed managers, promoters and implementers in each division, and has established an internal compliance promotion system. In addition, the Compliance Committee, chaired by an external expert (lawyer), has been established as the Special Committee that responds to consultations with the President. We are working to heighten the awareness among all executives and employees and further ensure compliance by establishing a system to set stricter disciplinary actions, etc., against any legal and other violations committed by executives and employees and to call for compliance with the Antimonopoly Act, implementing a range of measures based on the recommendations by the Compliance Committee and compliance training in each division, and taking other steps.

Whistleblowing and Consultation System
Based on the Whistleblower Protection Act, at the Taise Group, we have established an internal whistleblowing system (the Corporate Ethics Helpline / Group Helpline / Whistleblowing System) in which executives and employees as well as external parties (staff of partner companies [primary suppliers] that have a direct contractual relationship with the Company) can report and consult on illegal acts including bribery and other corruption committed by executives and employees and acts that violate (or an act intended to violate) the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, and we have established consultation desks in-house and at an external organization (a law firm). The system also allows anonymous reporting to obtain information clues on a wide range of violations. In addition, to enhance the effectiveness of the system, we actively conduct educational activities such as distributing the Help Line Cards summarizing the outline of the system to all executives and employees and introducing the contents and operational results of the system through e-learning and Compliance Newsletter.
In response to reports received, we will investigate the facts of the report received and take corrective action as required. In doing so, we ensure that the whistleblower’s information is kept confidential and strictly follows internal regulations to ensure that the whistleblowers are not treated disadvantageously for reporting.
For external stakeholders who do not have a direct contractual relationship with the Company, our website provides inquiries on human rights, environmental issues and other issues.

Activities / Efforts
Compliance Education and Training
At Taisei Corporation, we issue Compliance Newsletter for all executives and employees once a month to raise compliance awareness. We also conduct compliance training via e-learning including anti-corruption twice a year. Attendance rate at compliance training in FY2023 was 100%.
In addition, to strengthen compliance throughout the Group, we conduct Group compliance hearings to share information and exchange views on legal issues with domestic Group companies. Through these initiatives, we strive to ensure thorough compliance through communication.
Furthermore, compliance training is conducted for our partner companies (specialized contractors) to ensure thorough compliance throughout the supply chain.
To improve awareness, we will continuously educate stakeholders on important topics.
Education / training | Topics covered in recent years |

Conduct Compliance Questionnaire (Annually)
The Taisei Group conducts the Compliance Questionnaire for all executives and employees with the aim of understanding the current status and issues related to compliance and further promoting compliance.
The results of the questionnaire are analyzed, measures are considered, reported to top management, and disclosed to all executives and employees through the Compliance Newsletter, and necessary measures are taken in cooperation with related departments to promote compliance.
Education and Awareness Initiatives for the Supply Chain
Collaboration with our subcontractors and suppliers is essential to ensuring thorough compliance throughout the Group’s business activities. To enhance compliance awareness among them, the Compliance Promotion Section conducts training sessions for their business owners during safety conferences held at each of our branches. We will continue to implement education and awareness programs for our subcontractors and suppliers.
Political Contributions
As part of its social contribution activities, Taisei Corporation makes political contributions when necessary. When making political contributions, we thoroughly comply with the Political Funds Control Act and conduct a rigorous review based on procedures pursuant to our internal rules, namely, the “Code of Conduct on Relationship with Politicians and Disbursement of Expenses.” The total amount of political contributions made during FY2023 was 18 million yen.
Anti-Corruption Policy

Taisei supports the anticorruption provisions of the United Nations Global Compact which it signed in 2018. In accordance with Principle 10 ("Anti-Corruption") of the Global Compact, Taisei includes “Ensuring fair trade” “Maintenance of proper relationships with individuals or entities engaged in politics and government” and “Dealing with people, associations or organizations engaged in anti-social behavior” in its Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, in order to prevent coercion, bribery, money laundering, obstruction of justice and the various other forms of corruption. This makes it clear that the Taisei Group and Taisei personnel shall not offer or promise any illicit money or goods to clients and individual executives and employees of the client, and shall not, in their dealings with politicians and government officials (including foreign government officials), engage in activities that would violate criminal laws (such as those relating to bribery) or activities that may be understood as such, or agree to unreasonable demands made by antisocial forces or organizations. We have also established a code of conduct with regard to the Act on Prohibition of Private Monopolization and Maintenance of Fair Trade (Anti-Monopoly Act), and we also require employees to conduct themselves responsibly to ensure that there are no violations of the criminal laws relating to bid-rigging, the Anti-Monopoly Act and so on, in order to prevent corruption.
To educate the prevention of bribery for politicians and government officials (including foreign government officials), a small booklet entitled “Quick Guide to Compliance” has been prepared. Online education courses are also conducted for all employees to ensure that they understand that bid-rigging and other acts that obstruct fair competition (a comprehensive category that includes bribery and other corrupt practices) are strictly prohibited, in order to enhance employees' knowledge and awareness of the importance of preventing corruption.
With regard to relationships with foreign government officials, for which particular caution is needed, in FY 2020 we introduced a pre-check system as an anticorruption measure for foreign government officials, etc., and we are committed to preventing corrupt practices.
Moreover, when agents (distributors, representatives, consultants, agents etc.) are hired in connection with transactions with foreign government organizations or the like, a check is conducted in advance based on a standardized checklist and approval from the administration division is obtained, and the contract signed with the agent, etc. is required to establish matters relating to legal compliance.
Review of Compliance with the Group Action Guidelines and Handling of Violations
The Taisei Group has established a Sustainability Committee as a committee within the Board. The committee revises and abolishes the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole (hereinafter referred to as the “Group Action Guidelines”), discusses ways to ensure a thorough understanding of these Guidelines within the company, and determines the status of compliance with the Guidelines. The Board regularly monitors and directs the status of operation of the Corporate Ethics Helpline, the entity that has been established to receive reports and provide consultations on violations of the comprehensive Group Action Guidelines, including prevention of corruption in all its forms.
In the event of a violation of the Group Action Guidelines, such as a serious compliance violation, we initiate a thorough study and implement measures to prevent the recurrence of the violation. For this process, we strive to accurately ascertain the facts by investigating relevant factors, including related persons, the course of events, the nature and specifics of the violation, the amount of damage, and the impact on interested parties, and then report to relevant authorities as necessary.
The perpetrators are subjected to necessary disciplinary action, including dismissal, following a careful and rigorous review of the facts by the Board or the Management Committee, based on the Rules on Enforcement of the Compliance System for the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole.
In FY2023, there were no cases of legal action or payment of fines or penalties based on corrupt or anti-competitive behavior in our company. In addition, there were no dismissals due to corruption and bribery.
Impartial and Fair Transactions
Taisei Corporation has included “Promoting partnerships with subcontractors and suppliers” in its Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, emphasizing the importance of establishing fair and reliable relationships with its partners in the supply chain and conducting transactions on an equal footing. In August 2020, we prepared and announced the Declaration of Partnership Building which incorporates prosperous coexistence for the entire supply chain, new collaboration regardless of the company's scale and existing business relationships, and observance of “Promotion Standards” as defined in the Act on the Promotion of Subcontracting Small and Medium-sized Enterprises. Furthermore, in order to eliminate anti-social forces, we have included a condition in our basic contract with specialized subcontractors emphasizing that we do not conduct business with anti-social forces and affirming that the subcontractors and suppliers are not an anti-social force, and that if it is revealed to be otherwise, the contract may be canceled without notice.
We disseminate our stance on impartial and fair transactions in connection with preventing corruption to employees of the Company and Group companies as well as to our suppliers, including subcontractors and intermediaries.
We also cover impartial and fair transactions in our Taisei Group of Companies Sustainable Procurement Guidelines and work to reduce risks so as not to get involved in transactions with anti-social forces, corruption, bribery, and organizations engaging in inhumane labor.
Verification of Compliance with Laws and Regulations (Guidance)
To ensure the legitimacy of bids, Taisei Corporation operates an in-house system whereby the heads of branch offices confirm that there are no inappropriate acts in the process of bidding operations, produce the documents, and keep all bids on file.
Every year, the legal department verifies the legitimacy of bids and checks compliance with the Construction Business Act, the Antimonopoly Act and the Subcontractors Protection Act.
Specific Measures for Compliance with the Antimonopoly Act
The Company has established the Code of Conduct for Compliance with the Antimonopoly Act to eliminate and prevent any acts that could raise suspicions of violations of the Antimonopoly Act. This Code outlines the behavior guidelines for executives and employees, as well as the internal compliance framework. We are committed to implementing the following strict measures and educating our executives and employees.
Specific Initiatives
- Rules concerning contact with competitors (mandatory reporting when attending meetings and monitoring of email communications)
- Procedures for ensuring the propriety of bidding operations
- Establishment of an in-house voluntary reporting (leniency) system
- Formulation of an Antimonopoly Act Compliance Manual
- Implementation of e-learning for all executives and employees
- Training sessions by external experts for the sales and technical divisions involved in order-related operations
Tax Compliance
Taisei Corporation is aiming at complying with the laws and regulations and to fulfill our social responsibilities with common decency on the basis of our Group Action Guidelines. Under these Group Action Guidelines, we established its Tax Policy in August 2020 as a tax guideline, and is striving to fulfill its tax obligations appropriately. In addition, since FY2013, we have conducted an annual e-learning program to raise awareness of tax compliance, and we are working to disseminate our tax policy in relation to the contents of tax audits.
We are also working to reduce tax risks by encouraging all excecutives and employees to consult with the appropriate department if there are unusual transactions, etc.
Regular Rotation of Accounting Auditors (Executive Members)
Executive members of accounting auditors are rotated regularly in accordance with the regulations of auditing firms that ensure compliance with the Certified Public Accountants Act. In addition, the upper limits for periods that are continually involved and the intervals during which involvement is prohibited following rotation are as follows.
- Engagement Partner:
No more than 7 accounting periods, interval of 2 accounting periods - Lead Engagement Partner:
No more than 5 accounting periods, interval of 5 accounting periods
Thorough Awareness of Structure of Values and Policies
We are promoting awareness and adoption of our Structure of Values and Policies through group training, distribution of portable cards, and intranet postings. Since FY2011, we have been conducting an e-learning program each year to further disseminate and establish the structure while relating it to social needs and internal efforts.
In FY2023, we conducted an e-learning program for employees on the Taisei Group Philosophy, the Taisei Spirit and the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, and the participation rate was 95%.
Information and Intellectual Property Management
The sharing of information with many clients, subcontractors (specialized contractors, etc.) and other stakeholders in construction projects is essential in the construction industry. The Taisei Group includes "Management of Information and Intellectual Property Rights" in its Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, and Taisei implements various policies relating to information security. In addition to establishing the Policy to Protect Personal Information and Codes of Practice for the Use of Social Media, the Taisei Group has also established a Policy on Intellectual Property and faithfully implements intellectual property strategies for the creation, protection and use of intellectual property, for the mitigation of risks relating to intellectual property, and for the strategic use of brands.
