This paper deals with the result of the observations regarding the groundwater levels and water quality in Higashi-nomyo landslide area.So far it has been considered that the groundwater overflowed from the groundwater basin would permeate into the landslide slope located downward.This investigation revealed that the overflowed groundwater only exists at the top of the landslide slope while the water in the lower slope is derived from the deep layer and surface layer.
