Risk Management
Water Risk Assessment
The Group conducts water risk assessments on its properties using Aqueduct, a tool designed for that purpose. As a result, all properties built by the Group in fiscal 2023 (91 buildings in total: 71 in the residential sector and 20 in the urban development sector) were found to be located in “Low-medium” water risk areas and outside of “Medium-high” and higher water risk areas. Therefore, no water was taken from areas designated as “High” or “Extremely high” by the properties built in fiscal 2023. We will continue to periodically monitor the water risk.

Response to Soil Contamination/Water Pollution
When acquiring land, the Group investigates the history of land use of the site and, if soil contamination is suspected, hires specialists to conduct soil surveys. If soil contamination is detected, we take appropriate measures including removal and containment of the contaminated soil in accordance with the Soil Contamination Countermeasures Act and other relevant laws and regulations.
Similarly, we take appropriate measures if a problem with water pollution is detected.
The Group takes appropriate action to prevent environmental impact and detrimental health effects caused by soil contamination and chemical substances.

Initiatives
Effective Utilization of Water Resources
The Group intends to reduce water consumption throughout the life cycles of products and services.
Introduction of Water-saving Devices Upon New Construction and When Performing Renovations
Water and hot water saving devices have been made standard equipment when developing housing, office buildings, retail facilities, logistics facilities, and other structures in accordance with design and construction standards and quality manuals. In addition, fixtures are systematically replaced with water-saving devices when performing renovations.
Details of design and construction standards and quality manuals can be found here.
Collaborating with External Partners to Reduce Water Use
The Group is a formal member of the Environmental Committee in the Real Estate Companies Association of Japan. In 2013, this committee formulated the Real Estate Industry Environmental Action Plan, which includes specific initiatives such as introducing highly effective water-saving fixtures and automatic faucets and flushing systems. It is aiming for the entire industry to work together in an effort to reduce water usage.
