In this paper, we report on the process by which Saitama Medical School, the medical department of Saitama Prefectural University, which also has departments of nursing, physiotherapy, occupational therapy, child and social welfare, and health science, realized interprofessional （IP） practice by interuniversity cooperation and report on the results of that process. For the realization of IP education （IPE） through interuniversity cooperation, university presidents’ must share their recognition of the mutual benefits and importance of IPE, and the teaching staff must work together towards a common goal. The benefits of locally based IPE （IP practice） of Saitama Prefectural University were that medical students became more aware of their role as caregivers for the entirety of their patients’ lives and that students of other departments were able to participate in IP work with medical students as part of their undergraduate education, to form partnerships with physicians, and to clarify the special nature of their occupations.
