Effective Utilization of Water Resources

Approach and Policies

Group Policy (Environment)

Increased costs for imported materials due to water shortages and water pollution as well as difficulties in procuring water as a result of climate change and abnormal weather patterns may significantly affect our future businesses. This is a key management concern for the Group, which uses large amounts of water resources in its business activities in Japan and overseas including the real estate business, urban development, and sports club operation.
Based on this understanding, the Group is working with design and construction companies and other suppliers to make capital investments and provide products and services that lead to the effective utilization of water resources.
