In this paper, the authors describe how a multicultural university in Japan has developed a comprehensive scheme to cultivate future global leaders using its on-campus resources. Under its 2030 vision, the university has developed a campus-wide, comprehensive scheme to develop students who can work collaboratively with others despite cultural and language differences to create new values for the future. The paper elaborates on four of such programs and assesses how each contributes to the development of global leaders: Peer Leader Training, Teaching Assistant Training, Global Communication Program, and Honors Program. Each is not operated independently of one another but is part of a multilateral campus-wide scheme. Taken as a whole, the scheme has proven successful in creating a sustainable on-campus cycle of leadership development, in both curricular and noncurricular areas, in which the leaders developed in one program go on to assume leadership roles in another.
