Many climatic regional divisions have been produced by workers using macroscale, larger than mesoscale, analyses. In their divisions, lines showing the boundary between two nieghbouring areas were set on natural boundaries such as mountains, But from the stand point of microscale analysis, it can be said that mountains are broad land areas and have relatively great altitudinal differences. Accordingly, we can divide areas occupied by mountains into many sub-areas using micro climatic factors. In other words, boundary lines necessarily have width as a shifting belt between the two neighbouring areas. The clarify the characteristics of climate in the range of the Oku-chichibu mountains and surrounding area, regional division was carried out using the following procedure. First, the hyther graphs for about 70 observatory stations located in the range were drawn by the ordinary method. Next, the graphs were classified by differences of their pattern. The patterns were divided as follows, When the maximum monthly precipitation appeared in June this was classified as "A", in July as"B", August "C", and September "D", To these classes, some subclasses showing the variation of the number of crossing points made by two seasonal zigzag lines from winter to summer and from summer to winter on the graph were added. The regional divisions by this method, showed similar results to some of the existing divisions by other workers, and clarified some details, The characteristiecs of each dicided sub-area were analysed by the P/E index of Thornthwaite, the coefficient of humidity of Angstrom, Koppen's precipitation effectiveness, and Kira's moisture index.
