Based on detailed observation of slope form and regolith characteristics, this paper discusses the spatial changes of slope processes and their differences in intensity and frequency on both segments seperated by the lower convex break of slope in a small watershed in the Omatsuzawa Hills. The detailed observation of slope morphology and grain-size analysis of regolith reveal that slope processes are prevalent both on the upper and that lower slope segments in the recent past and more frequent and intensive slope processes were prevailed on the lower slope segment. The lower convex break of slope designated as the Postglacial Dissection Front is a result of more active erosion on the segment lower than the break, but it does not mean non-occurrences of slope processes on the segment upper than the break.
