The relationships between the differential erosion topography and the slope failures on the Mt. Kano-zan and its environs in the Boso peninsula, Japan have been discussed. The results are as follows.<BR>The geology consists of sedimentary rock formations can divided into two types. First one is sandstone rich formation type and the other type is mudstone rich formation. The former area is formed high relief, low slope angle and low valley density. The later is formed low relief, high slope angle and high valley density. It is considered that the main facter is based on the low potential of erosion derived from decreasing surface stream which caused on permeability of unconsolidated sandstone.<BR>The phenomena of slope failures are main agency of the processes beneath the surface layer on the mountain slope of the Kano-zan and its environs. The distribution of the slope failures are consolidated on the mountains which composed of low relief, high slope angle and valley density. This is very important phenomena of the main agency of the aifferetial erosion topography in the humid temperature area.
