The cultural spherical consideration is a methodology of the cultural sphere applied to geography. In other words, its substantial speciality lies in grasping a cultural sphere as a regional whole.
By the region in cultural spherical consideration is meant a chronological system which has been completed historically and leaves its mark on the surface of the earth.
The cultural contents of a region studied may be determined be those of the cultural center. Accordingly, the principle of geographic division is to consider as a unit areas having a similar culture with differences of regional structure between the cultural center and the cultural outer zone. In short, it is the study of the particular from and structure of a cultural sphere zone and of a monistic geographical division having a cultural center.
Because the cultural spherical consideration is based on this limited method, geographic division in the prehistoric geography utilizing this method should also be limited. Nevertheless, this method has its peculiar methodological content.
On the other hand, prehistoric division ba ed upon regional study may grasp the same regions as plural geographical bodies. But this method, having no definite methodological grounds, should perhaps be reserved for future discussions. In that case, the method of geographic division by the cultural spherical consideration should be regarded as more than merely a suggestion.
