Contributions from the Department of Vegetation Science, Institute of Environmental Science & Technology, Yokohama Natlonal University, No.120.The purpose of the present paper is to describe the horizontal and vertical distribution of evergreen and summergreen broad-leaved forests in Japan. The evergreen broad-leaved forest, the characteristic vegetation of the Japanese Archipelago, is mostly coppice forest, i. e. secondary forest ; the natural forest is hardly left intact. In addition the evergreen species increase in number, and the Eg-Quotient MIYAWAIKI 1979 becomes higher in the vegetation of the evergreen broad-leaved forest in the lower latitudes. On the other hand, the natural deciduous forest still remains in northern Honshu and Hokkaido. The secondary deciduous forest, dominated by Quercus serrata or Carpinus spp., tends to extend itself not only in its original vegetation region, but also to some parts of the evergreen broad-leaved forest region.
