Water Resources

Policy, Concept, and System

As the lack of water worldwide becomes even more severe, developed nations and the rest of the world require ongoing improvements for the efficient use of water. The Tokyo Tatemono Group has raised resource-saving activities that are kind to the earth as one part of the Group Environmental Policy to recognize the importance of water resources, work at water-saving activities and the reduction of our environmental impact through every opportunity while striving to conserve water resources.

Water Resource Initiatives in the Office Buildings Business

In the office buildings owned and operated by Tokyo Tatemono, we have formulated a medium- to long-term repair and investment plan in 20-year increments. We promote systematic renovation construction as well as strive to introduce equipment that contributes to a reduction in the environmental impact during that renovation construction.
