Abstract
30years have passed after the first residents came into Tama New Town. In these days the problems on Tama New Town have been changed from the development issue to the maintenance or its sustainability. In order to make Tama New Town more sustainable, we have to know the demands or complaints of the second generation who were born there. But it has been difficult to make their behavior clear because of their privacy. This study aims to show when, how and why the second generation people in Tama New Town leave their home. We sent the questionnaires to both the first generation and the second generation living in Tama New Town and indicate some characteristics of their behavior.
