Water Risk Assessment

The Group owns many office buildings and other properties, and the majority of water used in the value chain is used within these properties. We conduct water risk assessments on these properties using Aqueduct, a tool designed for that purpose. Water risks for properties under development for fiscal year ended March 2025 are currently being compiled and confirmed.

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 majority of water used by the Group is in tenant buildings and our own facilities (such as sports gyms). Most of the water is used for daily life, and is properly disposed of in accordance with the laws and regulations of each local government. In addition, to further reduce our environmental impact, we are also working to reduce water consumption throughout the life cycle of our 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.
