In this paper, we present the temporal changes of Cs-137 depth distributions in forest floor of the evergreen coniferous forests in Fukushima by applying of a cluster analysis to the Cs-137 depth distribution in the forest floor obtained annually about 70-80 points from 2014 to 2020. The results show the temporal changes in the Cs-137 amount decreasing in the litter layer and increasing in the soil layer as a general trend. However, the progress of the Cs migration from the litter to soil layer is distinctly different in each investigation site.
