Historical records of large slope failures in Japan and foreign countries were collected andanalyzed to investigate occurrence frequency of the large slope failures and some dynamical andgeometrical features of debris deposits of the slope failures.It is shown that large slope failures have occurred in Japan much more frequently than inWestern countries. The relationship between the volume of slided debris and the equivalentcoefficient of friction for the debris motion is common to Japan and Western countries. Thefeatures of deposits spreading of slided debris showed a similar relationship between deposit areaand volume, but different shape over a wide range of debris volume with various types of slopefailures.
