Basic Approach
Inefficient use of water leads to waste of resources and adverse effects on the ecosystem. This not only has a negative impact on the global environment, but also increases building operation costs and regulatory compliance costs, and can become a deteriorating factor for the economic value of real estate.
With regard to water usage issues, Japan has set regulations on wastewater discharge, including the Water Pollution Prevention Act. Depending on its class and region, real estate may also be subject to separate regional environmental regulations.
In light of our understanding of these issues, the Group maintains an appropriate understanding and manages the status of water usage within real estate management operations. We also make various efforts to improve water usage efficiency beyond legal compliance levels

Specific Initiatives
Business Activities in Water-stressed Regions
The Heiwa Real Estate Group does not earn revenue from business activities in regions where water stress is a concern, namely, regions with risk scores of three or above (High, Extremely High) based on the World Resource Institute (WRI) Aqueduct Survey.
Further, with regard to domestic business activities, Japan has been identified as having Low–Medium risks related to water and is certified as a region with relatively low water stress.
Use of Rainwater and Well Water
Group efforts to effectively utilize water resources include the installation of storage facilities facilitating the daily use of rainwater and the effective use of well water.
Introduction of Water-Saving Equipment
We are working to reduce the amount of water used at existing properties by gradually promoting renovation work facilitating the conversion to water-saving equipment.
Cooperation with Business Partner
We established the Tenant Guidelines for Environmental Concerns and call on everyone in the Group and all our business partners to help conserve water.
Additionally, lease agreements with tenants stipulate cooperation with environmental performance initiatives, specifying efforts that include remembering to shut of water faucets and prevent leaks.
