 Due to the strong wind of the typhoon, a lot of the houses located on the right side to the running direction of the typhoon (dangerous semicircle) were damaged.
 This paper investigates the characteristics of the house damage and the recovery process in Nagasaki prefecture, by both field survey and questionnaire, and also topographic features and the direction of the house damage, its type of roof tile, environ's topographic features and the direction of the wind. Finally, some suggestions are made for the reduction of house damage due to typhoon.
