In this paper, a topographical background of vegetation change in the Boso hills located in south Chiba is studied. Although the region includes altitudes up to about 350m above the sea level, the hills are comprised of richly steep and complicated terrains. In addition, in the narrow upper area of the hills, the vegetation spans various climactic regions in a compressed mosaic-like distribution called the 'SUNDUMARI' effect. In order to describe this phenomenon, this study used an open-source GRASS GIS (Geographic Information System) and 10m precision DEM (Digital Elevation Model) data to focus on localized climatic phenomena. This research mainly uses r.sun command in GRASS GIS packages which are able to calculate global solar radiation in this area. A comparison of the calculated results and actual measured climatic parameters is still difficult since the number of observation points are limited. Results from the preliminary study however have confirmed that solar radiation has a great impact on the vegetation.
