• Landform Divisions of Japan

抄録

This article presents a basis for the subdivision of Japan into landform divisions, and to proceed to give the names and locations of the divisions. The fundamental premise in determining landform divisions is a fact that Japan is a single structural and geomorphologic unit from the world or the continental viewpoint, and the whole country is included in the Circum-Pacific Orogenic Zone. Therefore, the orogenc processes that have had much to do in forming the major landforrn features are considered to be the fundamental basis for determining the primary landform units.<BR>The following four primary landform divisions or Regions are differentiated by essential difference in recent orogenic movements, landform features, structures and means of coalescence of those arcs. They are ; A) Hokkaido Proper Region B) Northeast Region C) Central Region D) Southwest Region. The latter three regions are each composed of two or more subregions which coincide with the major tectonic units. Each traditional tectonic unit is taken as an independent subregion. These regions and subregions in turn are divided into districts on the basis of the differing effects of endogenic processes such as natures and amount of earth movements or volcanic activities. The districts are again divided into Sections en the basis of minor landform features resulting from either endogenic or exogenic processes. According to the above items, four regions, eight subregions, 51 districts and 240 sections have been established.
