Abstract
There are many areas in Iwate prefecture that are at risk of landslides and other sediment]related disasters. Moreover, the percentage of landslide prone areas with preventative works in place is quite low;10% lower than the national average. As a result of the 2002 Kamaishi landslide, Iwate Prefecture set forth some new projects in 2004, one of which was a project to promote the removal of housing from landslide risk areas. In this project, Iwate Prefecture independently adds funds to an existing national system to promote the active relocation of housing from landslide risk areas. There are few reports about the housing relocation from areas subject to disaster. Residents who used the system, and administrators in charge of this system, were interviewed to inquire into the present condition and issues facing the system.
