From a framework of this study, modern society may be explained by a paradigm transformation from ascription to achievement and also from particularism to universalism. According to this hypothesis, Japanese university society has not developed successfully for more than the closed society to the opened society. This paper intends to deal with the Japanese differentiated university stratification, which has been formed among these value orientations by connection of particularism and ascription, with a focus on its effects on the academic productivity including both research and teaching productivity. For example, a closed academic structure with an inbreeding mechanism in tate-shakai (vertical society) has brought about a great deal of effect either positively or negatively on academic system throughout the country. We intend to discuss the reasons behind the declining symptom of academic productivity of the university on the basis of the given framework.
