In this paper, we analyze the regional structure by using migration data of matriculates between prefectures. We analyze the data using the method of Huff’s model through three stages which differs in the way of setting unknown coefficients. Unknowns at the first stage are "Distance attenuation coefficient" and "Regional coefficients". "Regional coefficients" are proportional to their attractions. The distance attenuation coefficient is fixed at the second stage, and only regional coefficients are set to unknowns. At the third stage, regional coefficients are also set to given, virtual maps of matriculate’s migration is shown by the method of applying the multi-dimensional scaling method.

School basic survey (1993-2007) is used for the data of the migration of matriculates. The number of matriculate’s migrations decreases in proportion to the distance. Because a lot of matriculates come from the self-prefecture, we focus it on this number. Finally, we analyze time series of virtual maps of matriculate’s migration.
