The globalization of economic activities progresses worldwide. The internationalization of higher education institutions is required to adapt itself to the situation. Particularly, the top universities of each country are expected to produce very significant research achievements and to recruit and educate excellent students from all over the world. Furthermore, in the general university, it is necessary to create a learning environment conducive to training which increases the rate of employment of globally-talented graduates. It is necessary to internationalize the educational and research activities of university academic staff to accept foreign students, send Japanese students to foreign universities and conduct an educational program in the English language. The purpose of this study is to determine the determinants of internationalizing the educational and research activities of the university academic staff by clarifying the attributes, consciousness, and environment of university academic staff which are related to the internationalization of educational and research activities of academic staff in Japanese universities.
