In consequence of statistical study on landslides which took place on the upper reach of Tenryu river caused by heavy rain of June 1961, the total area of landslides in a drainage basin increases as a sigmoid curve but the mean area of landslides doesn't expand accompanied with increase of precipitation, was found. Therefore it could be concluded that increase of total area of landslides in a drainage basin is performed by increase of number of landslides but not by expands of area of each landslides.
