Occupational Health and Safety
Policies and Basic Approach
The Taisei Group, in its “Action Guidelines for Taisei Personnel and the Taisei Group as a Whole,” emphasizes maintaining a safe and health working environment, and strive to prevent occupational accidents. Especially in construction activities, the Group commits to adhering to laws, regulations, internal standards, and safety plans. We prioritize ensuring the safety of construction personnel and give utmost importance to ensuring community safety, which includes preventing accidents that may affect third parties. This commitment is deeply ingrained, ensuring strict adherence by all the Group’s executives and employees.
Additionally, within the Group’s [TAISEI VISION 2030] Achievement Plan / Policy on Business Foundation Development, we aim to “maintain zero fatal accidents, zero serious accidents, and zero environmental accidents.” Our Safety and Health Policy designates the Occupational Health and Safety Management System (“TAISEI OHSMS”), executed in a systematic and organized manner, as the cornerstone of our safety and health management approach. Group executives, employees, and professional contractors collaboratively work towards these aims.
We are also pioneering the adoption and enhancement of safety management and monitoring systems leveraging ICT and AI technologies. In collaboration with professional contractors, we are establishing a safety and health management system that clearly defines “responsibility and authority.”
Our ultimate goal is to create a work environment where individuals feel secure and to be recognized as a company that earns the trust and empathy of the wider community.

TAISEI OHSMS (Occupational Health and Safety Management System)
Based on the principle of “Safety First” as stated in its Safety and Health Policy, Taisei works with subcontractors and suppliers to operate its “TAISEI OHSMS*” occupational health and safety management system in a continuous and ongoing manner, with the objective of eliminating accidents and disasters, preventing accidents to third parties, and improving the health and safety level.
Taisei has established a Central Safety Committee (chaired by the Executive Vice President) made up of members appointed by the Management Committee. The Committee discusses safety management, the prevention of environmental accidents, and issues related to the health, safety and environmental management of subcontractors and suppliers, and reports and advices issues to the Management Committee. In addition, Branch Safety Committees, composed of branch supervisory health and safety managers, employees, and employee’s union, also meet regularly to hold discussions with employee’s union.
As one part of the Plan-Do-Check-Act (PDCA) cycle based on the “TAISEI OHSMS”, we conduct risk assessments (for example, when creating construction and health and safety plans after holding review meetings when a construction project has been acquired, and when advance reviews are conducted by the branch for plans concerning priority dangerous work operations). In addition, we also have the head office and branches conduct health and safety patrols at all sites where work is being done once construction starts, in order to check the implementation and operational status of health and safety plans and to conduct a risk assessment, and improvements and corrective action are conducted as needed in order to continually improve the level of health and safety.

* Our proprietary occupational health and safety management system developed in reference to the guidelines issued by the ILO and the Ministry of Health, Labour and Welfare. As November of fy2021, none of our business sites has obtained OHSAS 18001 certification.
Our Civil Engineering Division acquires certification of ISO45001, an international standard on occupational health and safety (OH&S) management system, and operates the system in all civil engineering construction worksites in Japan. (As of December 2024, the number of worksites operating the OH&S management system (Civil Engineering: 267) / all worksites (Civil Engineering and Building Construction: 744) =coverage 35.9%)
Activities / Efforts
Risk Assessment
Taisei Corporation implements risk management based on the “TAISEI OHSMS” occupational health and safety management system. Risk assessment is categorized as follows:
- Company-wide shared risk assessment, which is implemented comprehensively by the head office
- Branch office risk assessment, which is implemented at each branch office and
- Worksite risk assessment, which is implemented before work starts at each construction site.
These risk management initiatives are carried out at all existing and new worksites.
Moreover, for new worksites, branch offices make sure to thoroughly identify and mitigate risks as well as implement countermeasures during the construction plan review stage. By ensuring the implementation of risk assessment, dangerous and hazardous factors that may lead to accidents and disasters are eliminated or reduced, or necessary measures are taken to manage them as part of our efforts towards continuous enhancement of health and safety standards in conjunction with daily safety management PCDA cycles.
In 2023, there were 62 accidents at Taisei Corporation on a non-consolidated basis that required time off from work (as compared to 36 in 2022), resulting in the frequency rate of 0.51 (0.32 in 2022). There were zero fatal accidents. In 2023, the number of annual fatalities from accidents were zero for the second consecutive year.
When analyzing accidents that required time off from work in 2023, the most common type of accident was "fall accidents" (27.4%), followed by "machine-related accidents," "falls from less than 2 meters," and "heat stroke." Whenever an accident occurs, we thoroughly investigate the cause and take measures to prevent any recurrence. We are also working to eliminate similar accidents by sharing case studies on accidents within the company and with subcontractors and suppliers.
The main causes of "fall accidents" were tripping over uneven floors or over materials, equipment, and other items left in passages, so we work to prevent recurrences by making sure that working passages are kept clear and that sites remain tidy. As for "machine-related accidents," there have been many accidents caused by heavy machinery catching workers or materials being lifted by crane, so we check the skills of workers and provide guidance, and also instruct those with knowledge to ensure that they check the safety functions of machines. To prevent heat stroke, we promote the use of air-conditioned clothing, water-cooled clothing, etc., manage air conditioning in break rooms, and distribute free salt tablets and beverages. We also encourage employees to take more frequent breaks on days when extreme heat is expected, and we are working to prevent heat stroke through a comprehensive improvement in wellness.
In 2024, we continuously implement key measures such as the major priority for specialized contractors to eliminate fatal accidents and ensure a safe working environment under abnormal weather.
＜Five areas of focus for specialized contractors＞
Approach: Establish a more autonomous safety management system centered around business partners and site supervisors
- 1Ensuring dispatch training programs are conducted twice a year for all subcontractors and enhancing program content
- 2Securing the placement of safety and health managers and site supervisors as well as promoting advanced-level training
- 3Creating work procedure manuals containing accumulated know-how and ensuring they are circulated among the relevant personnel
- 4Preventing unsafe behavior through the board of site supervisor activities (such as calling out and responding)
- 5Accurate reporting of worker health conditions by all subcontractors, and proper placement by business partners and site supervisors based on medical advice (strengthening response to the onset of chronic illness on-site) and appropriate management of working hours by business partners

Initiatives at Construction Sites
Making Technical Improvements in Accident Analysis (DX and Secondary Use of Work-at-Site Data, Etc.)
At our worksites, we introduced the “Construction Site Face Recognition for Green Site” system in October 2022 and have been expanding its use. We analyze accident trends to proactively prevent future incidents using employment data obtained through the facial recognition system. In addition, safety performance and frequency rates for each specialized contractor are monitored based on employment and accident data. We evaluate and select contractors based on their safety records and frequency rates, which are derived from employment and accident data. By doing so, we are enhancing overall safety levels.
Implementation Status of Safety and Health Patrol
As one part of health and safety management based on the “TAISEI OHSMS” occupational health and safety management system, Taisei Corporation conducts patrols to confirm the safety and hygiene status at construction sites. In addition to patrols by Taisei employees at the head office and branch offices and patrols by the owners and safety personnel of subcontractors and suppliers and so on, the President himself visits and patrols construction sites during National Safety Week to make sure that each and every employee and worker shares the company's strong commitment to its “Safety First” policy.
To ensure that each and every employee and worker shares the company's strong commitment to our “Safety First” policy, the President Aikawa himself visited and patrolled construction sites at the Tokyo, Kansai, Chubu, and Tohoku branches at National Safety Week FY2023. Following these patrols, the President provided instructions to business owners, contract workers, and company employees. He instructed them to conduct thorough safety management based on the situation at each construction site and to put together reliable safety processes. He then requested that employees, the Board of Managers, and the leaders of the workers, make a scrum to ensure thorough safety management. The construction site patrols by the President are conducted to impress upon all employees and subcontractors and suppliers the firm commitment to safety on the part of the company's top management.

To Enhance Environmental Training and Patrols
To prevent and eliminate environmental accidents, we conduct environmental education and patrols through the Safety, Health and Environment Cooperation Association, which includes all specialized contractors involved in our projects. These initiatives focus on identifying and preventing environmental risks.
Educational Support for Cooperating Companies
By working closely with the Taisei Health, Safety and Environment Cooperation Association, comprising cooperative companies in Japan, we make efforts to prevent accidents and disasters. The members of the association participate in the Safety Conference held in January and Safety Promotion Conference in June every year. To prevent accidents and disasters, we utilize a bulletin, “Kyoryoku (Corporation)” and a list of disastrous cases for the education and guidance of safety and sanitation management.
Awards system
Taisei has established several awards in an effort to improve the quality of health and safety, including the President's Commendation, the President's Award (safety and hygiene category), the President's Merit Award (Safety Order of Merit), and the Safety and Hygiene Environment Cooperative Federation Chairman's Award (Special Award). In addition, each year during National Safety Week (July 1 - 7), the Ministry of Health, Labor and Welfare presents the Minister of Health, Labor and Welfare Award to workplaces for excellence in workplace health and safety and persons of merit who have made a major contribution to the long-term improvement and development of safety and hygiene standards of a region, organization or relevant workplace. At Taisei Corporation, the Taisei/Rinkai Nissan/Honma Special Joint Venture Nagoya Central Stormwater Main Line Sewerage Construction Worksite received an award for excellence.
Communication with Cooperating Companies
National Safety Conference
The 2024 National Safety Conference was held on February 21, 2024. At the opening of the conference, the president expressed respect and gratitude to employees and members of the cooperative association for achieving zero fatal accidents over the past year. He also set forth this year's safety goals of a fatality frequency rate of less than 0.40 and zero serious accidents, urging a sincere effort toward achieving these safety objectives, with the company and its partners working together as one.
Supporting Soyukai* Member Companies to Secure Appropriate Workforce
We provide online training that incorporates the metaverse to support the development of skilled workers for Soyukai members. Additionally, we assist in their recruitment activities by organizing joint company briefings for Soyukai members. We also offer resources and information on balancing work and caregiving responsibilities to help prevent employee turnover.
At our worksites, we introduced the “Construction Site Face Recognition for Green Site” system in October 2022 and have been expanding its use. We analyze accident trends to proactively prevent future incidents using employment data obtained through the facial recognition system.
In addition, safety performance and frequency rates for each contractor are monitored based on employment and accident data. We evaluate and select contractors based on their safety records and frequency rates, which are derived from employment and accident data. By doing so, we are enhancing overall safety levels.

Soyukai Central Council Meeting
The Soyukai Central Council Meeting, attended by Taisei Corporation executives and leaders from Soyukai, an organization that aims for mutual prosperity, was held on September 29, 2023. The meeting facilitated active discussions on securing skilled labor, improving productivity, and other topics.
Construction Career Up System (CCUS)
The Construction Career Up System (CCUS) is a system that aims to promote the spread and establishment of a common system infrastructure for the construction industry, with the aim of creating a construction industry in which skilled construction workers are treated appropriately in accordance with their skills and experience. The system is being promoted by the Ministry of Land, Infrastructure, Transport and Tourism in collaboration with construction industry organizations such as the Japan Federation of Construction Contractors (Nikkenren), the Japan Construction Engineers' Association (Zenken), the Federation of Construction Industry Associations (Kensenren), and the National Federation of Construction Worker's Unions (Zenkensoren), with the aim of promoting the spread of the system across both the public and private sectors.
In May 2021, in line with the new targets set by Nikkenren, we established the “CCUS Dissemination and Promotion Roadmap.” We have been progressing well towards our annual targets and worksite registration rate of CCUS reached 100% in FY2023.
Upgrading Safety Training for Our Employees
Taisei Corporation provides employee training to deepen employee's understanding of accident and disaster prevention, improvement of health and safety awareness, and laws and regulations related to safety. Education is provided based on the job level of the employee according to year of enrollment and job functions in order to provide the employee with basic knowledge needed for the job. In addition, a monthly Accident and Disaster Report is distributed on the Intranet to share information including disaster analysis, case studies of disasters and ways to prevent disasters.
Starting in January 2024, we launched the Safety Academy for employees who are inexperienced in site management. This academy allows participants to simulate potential accidents and industrial disasters scenarios on construction sites.
Taisei Corporation prioritizes the creation of safe working environments for every worker. With the introduction of this academy, we are committed to enhancing employee awareness of danger and preventing accidents and industrial disasters before they occur. We plan to use this academy for training to enhance the technical skills of our group company employees and for Soyukai's safety and health managers.
In 2023, 1,457 employees participated in a variety of safety training for employees who carry out on-site work.
