Environmental Initiatives

Concept of Environmental Initiatives

Our goal is to utilize and revitalize the huge existing building stock that exists in the Japanese real estate market.

Tosei Reit considers that one way to address environmental issues is to maintain the value of existing aged properties it holds and to use them as offices and housing for a long period of time by systematically implementing capital expenditures for these buildings and facilities. We also believe that the renewal of air-conditioning equipment and electrical equipment through replacement has been effective in improving energy efficiency.
In addition, based on the Environmental Policy established by Tosei, The asset management company promotes environmental initiatives in Tosei Reit.
