Natural regions of Japan were devised through multivariate analysis using several databases related to the natural environmental elements, the preparation of which has rapidly progressed in recent years. The analysis was performed by making each sample area approximately 1 km2 and using ten environmental elements. Firstly the sample areas were classified separately on the basis of climatic elements, land characteristics, and vegetation types. Then these three classifications were integrated to identify natural regions. For qualitative data, Hayashi's quantification theory III was applied while factor analysis was applied for quantitative data to understand the structure of the natural environment. Sample scores and factor scores were classified into groups by cluster analysis. The result of classification obtained from this was used to make a map of integrated natural regions. The relationship between integrated natural regions and three basic regions was analyzed to clarify the characteristics of each region. As a result, the Whole of Japan was classified into ten natural regions, in which the functional relationships of natural environmental elements were clarified.
