Since several years ago, slope failures caused by heavy rainfall occur at many places in Japan.They damage heavily the inhavitants and the houses.
The present paper deals with the results of investigation concerning the geotechnical conditions such as topographical, geological and soil mechanical conditions and the rainfall conditions which give rise to slope failures.These results will be available for the prediction of slope failures in the future.
