This study summarizes the forty-year history of the Shirahige East Area Disaster Prevention Base provided with emergency equipment and catastrophe relief measures, which was developed from 1970s to1980s to reduce future disaster risk of Sumida Ward, and examines its management and disaster risk reduction activities directed by residents. As a result, the following became clear: (1) Maintenance costs and availability of emergency equipment has been changed according to changes in the surrounding circumstance, but it is still recognized as an important disaster prevention base; (2) Due to the aging of the housing complex residents, the capacity to accept evacuees from outside is declining, (3) Although the number of vulnerable buildings in the surrounding area has decreased and open space has increased as a whole, some high disaster risk districts still remain with population decline and aging.
