CSR | EnvironmentEfficient Use of Water Resources

Approach and Policies

The Nomura Real Estate Group 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.
As shortages of water resources become increasingly severe around the world, there may be substantial impacts on business in the future including risks in overseas business, higher costs for imported materials in conjunction with water shortages and water pollution, and difficulty procuring water as a result of climate change and abnormal weather. The Group is aware that this is a key management issue.
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 efficient use of water resources.


Management Structure

Nomura Real Estate Holdings’ executive vice president and Group COO has been made responsible for this issue for the Group, and the entire Group is working together to promote the efficient use of water resources.
In addition, the CSR Committee, which comprises Nomura Real Estate Holdings and Group company directors and others and is chaired by the Nomura Real Estate Holdings executive vice president, deliberates on and decides related policies and action plans.
Starting in fiscal 2018, targets regarding efficient water resource use were set, and the Committee is monitoring progress.


The Group is working to reduce its water use.
