Sustainability

In Japan, where a labor shortage has become a social issue, the role of a company that protects the safety and health of its stakeholders is considerable.
Our Group believes that on-site safety, the health of our employees, contractors and other stakeholders is essential to the growth of our business, and we are working to strengthen and operate our management system in accordance with social conditions, based on compliance with various laws and regulations.
In the Construction Division, the Safety and Health Committee of the Construction Business manages safety and health at construction sites.
Severe disasters and accidents that could lead to fatal accidents are reported to the Board of Directors. At the same time, the Health Committee and various vendors' associations discuss the pursuit of causes and measures to prevent recurrence, which are communicated and thoroughly implemented to employees and contractors.
In 2021, we established a new specialized department for employee health and assigned members to Business divisions in an effort to appropriately check working conditions and maintain employee health.

The Group convenes a Safety and Health Committee once a month, consisting of worker representatives (chief safety managers, safety managers, health supervisors, occupational physicians, and external experts such as certified social insurance labor consultants) from each work site. The meeting is held to share information and exchange opinions on matters related to occupational safety and health, such as the number of work-related accidents, the status of health checks, and the situation of overtime work. Important agenda items are reported to the Board of Directors, and all content is disseminated to all employees via the company's internal portal.
Furthermore, we carry out the following initiatives throughout the year for construction site employees and subcontractors, creating opportunities for them to safely continue their business activities with subcontractors in order to achieve zero accidents at construction sites.

Implementation of Training on Safety and Health Standards Related to Construction

We regularly conducts collective training sessions that include not only our employees but also our partner companies. Through these sessions, we aim to impart skills and knowledge, ensure adherence to work manuals, and promote health and safety at construction sites. In 2024, 772 people participated in the general meeting, and a total of 1,910 people attended regional sectional meetings and received training.

Initiatives involving the supply chain (partner companies)

In-house initiatives

* Single-family homes related business of Open House Development
Certain initiatives have been canceled in view of the situation regarding COVID-19.

In our group's single-family home business, we recognize that accidents at construction sites are a high-priority risk and conduct risk assessments to ensure occupational safety. When formulating annual health and safety management plans and conducting hazard prediction activities at construction sites, we strive to prevent accidents proactively. This is achieved by implementing safety patrols and introducing guidance item checklists to identify potential risks in advance and assess their likelihood and impact.
Furthermore, for both existing and new operations, we provide necessary guidance and take measures to ensure safety for employees and the surrounding environment at construction sites. This includes ensuring compliance with various laws and regulations, such as the Construction Business Act, and maintaining site health and safety standards.

We believe that maintaining and improving the health of our employees contributes to improved organizational energy and productivity.
Through our health management promotional system led by the President & CEO, we strive to create an environment in which our employees can continuously work in good health as part of our corporate social responsibility.
