The asymmetric cluster analysis was applied to the enrollement flow from high school to university among the Japanese prefectures to disclose and to compare university enrollment regions before and after the introduction of the Joint First Stage Achievement Test (JFSAT). The asymmetric cluster analysis used in the present study is characterized by two aspects. One is that it is based on the mean clustering so that small university enrollment regions can be disclosed as well. The other is that it allows the clustering based on self similarity. Eight university enrollment regions were disclosed before and after the JFSAT respectively, and seven of the eight were centered at same prefectures before and after the JFSAT, suggesting that university enrollment regions were almost unchanged. But there were differences in some respects. (a) After the JFSAT, university enrollment regions which were geographically not between the two largest university enrollment regions centered at Tokyo and Kyoto (north to the one centered at Tokyo or west to the one centered at Kyoto) became larger and more independent from the one centered at Tokyo. (b) After the JFSAT, university enrollment regions between the two largest enrollment regions did not become larger nor independent.
