This book discusses what internationalization practices are and the different ways that they are being implemented by higher education institutions in Japan, from a bottom-up perspective. It reflects the current situation faced by many Japanese universities in the context of the changing landscape in higher education and considerations in implementing changes to course curricula, programs, and university admissions with regard to internationalization. The four case studies presented provide readers with clear examples of how the internationalization of higher education institutions is developing within the Japanese higher education system, and the issues that different higher education institutions face in this process.
