Policies and Basic Approach

In accordance with the Taisei Group Philosophy "To Create a Vibrant Environment for All Members of Society," the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole states that all Group employees shall conduct business activities with respect for fundamental human rights and diversity.

Our Human Rights Policy defines contributing to achieving an inclusive society as our basic stance on respect for human rights. The contributions include committing to both internal and external responsibilities for respecting human rights, and fulfilling the corporate responsibilities voluntarily, positively and proactively as a corporate citizen so as not to make adverse impacts on human rights in relation to the business activities.

The Human Rights Policy emphasizes respect for the fundamental human rights and diversity of individuals, and prohibits any act that infringes on human rights, such as discrimination, harassment, and invasion of privacy on the grounds of race, nationality, religion, sex, sexual orientation and gender identity, age, social status, presence of disability, injury or illness and/or physical characteristics, etc. Based on the U.N.'s Guiding Principles on Business and Human Rights, Taisei observes laws and regulations, etc. related to human rights in countries and regions in which it conducts business activities. In addition, we support and respect international human rights standards such as the International Bill of Human Rights, which includes the Universal Declaration of Human Rights. In the event of a discrepancy between international human rights standards and national and regional laws and regulations, etc., Taisei seeks a method that achieves maximum respect for internationally recognized human rights. Our Group policy and basic perspective towards respecting human rights are communicated clearly through training and e-learning for employees; training and emails requesting self-assessments at the start of transactions for subcontractors and suppliers; and media such as integrated reports for all stakeholders including clients, shareholders, investors, subcontractors, suppliers, and business partners. We thus request support for these policies and respect for human rights.

Various Committees on Human Rights

Activities / Efforts

Continued Implementation of Human Rights Due Diligence

To fulfill its responsibility to respect human rights, the Group revised its Human Rights Policy in April 2022. In line with the United Nations Guiding Principles on Business and Human Rights and the Japanese government’s Guidelines on Respecting Human Rights in Responsible Supply Chains, the Group has established a human rights due diligence system and is continuously implementing related initiatives.
We collaborate with our subcontractors and suppliers to promote respect for human rights throughout the supply chain. The status of these initiatives is regularly reviewed and discussed at the Management Committee and reported to the Sustainability Committee and the Board for monitoring.
Drawing on insights gained from the implementation of various measures and dialogue with stakeholders, we will continuously review and improve our systems and initiatives, deepening our commitment to respecting human rights in partnership with our subcontractors and suppliers.

1. Maintain a commitment to meet the responsibility to respect human rights (Guiding Principle 16)

The Taisei Group's Human Rights Policy was formulated in 2015 and revised in April 2022. The Group's commitment to meeting its responsibility to ensure respect for human rights is communicated clearly both within and outside the Taisei Group companies. The basic position of the Taisei Group as regards respect for human rights is to voluntarily, positively and proactively exercise its responsibilities as a corporate citizen to ensure that its business activities do not negatively impact human rights, and to contribute to the achievement of an inclusive society. Taisei has also established a Human Rights Due Diligence framework to fulfill its responsibility to ensure respect for human rights.

The Human Rights Policy is posted on the official Taisei Group website, and clients and subcontractors, suppliers and other business partners are asked to support the Policy and maintain respect for human rights.

2. Identify and assess adverse impacts on human rights (Guiding Principle 18)

To identify and assess adverse impacts on human rights caused by existing or new projects of the Taisei Group, based on guidance and recommendations from an outside expert (Sompo Risk Management Inc.), a check was conducted by the Sustainable Procurement Council (currently called as Human Rights Due Diligence Subcommittee) and members of the Human Resources Division and International Operation Headquarters to identify adverse impacts on human rights (human rights risks) that are common to all industries and human rights risks that are specific to the construction industry and the Taisei Group, based on international guidance on human rights (the Human Rights Guidance Tool of the United Nations Environment Programme Finance Initiative (UNEP FI)).
The human rights risks that were identified — discrimination and harassment, long working hours, health and safety, bribery and corruption, migrant labor (foreign workers), child labor, forced labor etc. — were subjected to a quantitative analysis and assessment from the two aspects of "impact on human rights (degree of seriousness, number of people affected, possibility of remediation, likelihood of occurrence)" and "connection to Taisei." Following discussion at the Sustainability Committee and the Board, these were identified as "human rights issues that must be dealt with on a priority basis.” For these prioritized human rights issues, we have established specific measures to prevent and mitigate adverse impacts, evaluate their effectiveness, and are actively working on these efforts.

3. Prevent and mitigate adverse impacts (Guiding Principle 19)

For issues that are a priority for Taisei and Group company employees, the headquarters in charge of each issue plays the principal role in taking various corrective measures to achieve prevention or mitigation. Moreover, Taisei also works to deepen employees' understanding of the importance of ensuring respect for human rights through the educational activities of the Human Rights Awareness Promotion Committee that is chaired by the CSuO.

Furthermore, Taisei provides regular e-learning on human rights for all executives and employees to raise their awareness of human rights.

Issues that are a priority for the supply chain are studied by the Supply Chain WG of the Human Rights Due Diligence Subcommittee made up of responsible personnel from the Sustainability Management Promotion Division and relevant divisions (Civil Engineering, Building Construction, Procurement, and Safety Administration), and prevention and mitigation measures are reflected in the Sustainable Procurement Guidelines. Taisei works with subcontractors and suppliers to prevent or mitigate these issues. To ensure a thorough understanding on the part of subcontractors and suppliers, issuing and distributing the Taisei Group Supply Chain Sustainability Handbook (only in Japanese), training is conducted at the Safety Convention, and e-learning for subcontractors and suppliers is made available to conduct educational activities on an ongoing basis.

For issues that are a priority for clients, client employees and residents in the local community, the headquarters in charge of each issue plays the principal role in taking corrective measures to achieve prevention or mitigation.

4. Assess the effectiveness of activities (Guiding Principle 20)

The effectiveness of activities to resolve issues that are a priority for the employees of Taisei and Group companies is assessed through monitoring by various committees, checks an improvements based on company-wide risk management, and opinion surveys and engagement surveys.

To assess the effectiveness of activities to resolve issues that are a priority for the supply chain, annual self-assessment of subcontractors and suppliers is conducted, and based on the results subcontractors and suppliers are visited and audited and an exchange of views is conducted.

In addition, to prevent or mitigate human rights violations of foreign workers, vulnerable to human rights risks in the construction industry, in addition to the aforementioned self-assessment, a survey of the acceptance status of foreign technical interns was conducted for the owners of companies that employ such interns.

We conduct direct interviews with foreign technical interns periodically every year to confirm whether there is no adverse impact on human rights.

For activities with regard to issues that are a priority for clients, client employees and residents in the local community, the effectiveness is assessed by means of company-wide risk management and so on.

5. Provide explanations and disclose information (Guiding Principle 21)

The status of implementation of Human Rights Due Diligence activities is regularly reported to the Management Committee and the report is disclosed in a timely and appropriate manner on the official website, in Integrated Reports, etc.
In September 2025, the initiatives and the results of the effectiveness evaluation on each priority human rights issue implemented in FY2024 were reported to the Management Committee after confirmed and discussed in the Sustainability Promotion Committee in June and July 2025 and related future issues and measures were deliberated.
Details of the initiatives are in the following "Refer to" pages.

6. Remediation (Guiding Principle 22)

Contacts for various consultations regarding human rights violations have been established for consultations from all stakeholders within and outside companies, including foreign workers. In the event that the Taisei Group has been determined to be the cause of, or a contributing factor to, an adverse impact on human rights, Taisei takes prompt action using appropriate means to provide remediation and implement corrective action in accordance with its Human Rights Policy. We inform various consultation services to all stakeholders within and outside companies, establish and operate the system to enhance effectiveness of remedy and correction.

7. Dialogue with Stakeholders

With regard to the impact of its business activities on human rights, the Taisei Group employs the knowledge of outside specialized institutions and the like and conducts dialogue and discussions with stakeholders as needed to promote activities to ensure respect for human rights, based on its Human Rights Policy.

Moreover, with regard to significant human rights issues in the construction industry, the Taisei Group Human Rights Policy stresses the need to thoroughly eliminate human rights violations involving foreign workers in particular, and Taisei emphasizes respect for the human rights of foreign workers who are in a vulnerable position. From FY2022, Taisei has consecutively conducted interviews with foreign technical interns as well as exchanges of information with the owners of the companies that had accepted interns.

Furthermore, Taisei visits and audits primary and secondary subcontractors and suppliers as part of its Human Rights Due Diligence activities, in accordance with the United Nations Guiding Principles on Business and Human Rights, and on these occasions exchanges of views are held with company owners and best practices are shared.

An executive of Sustainability Division (Integrated) had a dialogue with an outside expert and has utilized the gained insights to deepen human rights initiatives.

Through these efforts, Taisei strives to determine the adverse impacts of the business activities of the Taisei Group on human rights, and continuously strives to prevent or reduce these impacts. Taisei also complies with laws and regulations for the prevention of human trafficking, child labor and forced labor, and those relating to equal work, equal compensation, immigrant labor and so on, and works to ensure respect for human rights.

8. Others

Participation in the Construction and Real Estate Human Rights Due Diligence Promotion Council

Taisei participates in the Construction and Real Estate Human Rights Due Diligence Promotion Council, which was established by developers and general contractors without regard to industry boundaries. We share the content of our initiatives related to human rights due diligence, and we conduct surveys and research on advanced cases to fulfill our responsibility to respect human rights.

Assessment of Adverse Human Rights Impacts in Business Processes

Starting in 2024, as part of our business processes, relevant personnel, including sales representatives, are required to assess potential adverse impacts on people and the environment when making policy decisions on bidding projects. This involves reviewing the business and construction plans for each project, and, when necessary, consulting with the Sustainability Division to consider measures to avoid, prevent, or mitigate such impacts. For example, if a project schedule is likely to result in excessive working hours for employees or workers, we may request that a more appropriate timeline be secured.

Human Rights Awareness Initiatives for Executives and Employees

At Taisei Corporation, we have created the TAISEI Sustainability Handbook, a training resource that explains our Human Rights Policy, human rights due diligence, and related sustainability initiatives. This handbook is distributed to all executives and employees to raise awareness. We also hold departmental briefings to ensure a thorough understanding of these principles throughout the organization.
To ensure each individual within the company fully understands the Human Rights Policy and can put respect for human rights into practice, we conduct annual e-learning training for all executives and employees. In addition, our human rights education is integrated into the company’s hierarchical and department-based training structure. We offer group training on a wide range of topics, including global human rights issues, Buraku issues, people with disabilities, LGBTQ+ issues, and workplace harassment.
We also provide specialized online training for personnel designated as human rights consultation contacts in each department. For management-level staff, we offer training videos focused on preventing and responding to harassment by a supervisor and bullying. Newly appointed members of our Human Rights Awareness Promotion Committee attend the Human Rights Awareness Supervisor Training sponsored by the Industrial Federation for Human Rights, Tokyo.
We also conduct various ongoing activities to promote human rights awareness, such as distributing a “Human Rights Handbook,” holding annual contests for human rights-themed slogans and essays, and recognizing outstanding submissions through awards.
