Abstract

In Japan, doctoral enrollment has been declining due to financial pressures and uncertain career paths. Limited demand from primary employers, including universities and industry, contributes significantly to the mismatch between PhD graduates and available opportunities. Beyond expertise, doctoral graduates require the ability to identify and address societal challenges, integrate knowledge across disciplines, and act proactively to succeed across diverse career paths. This paper elaborates on a university-wide interdisciplinary graduate program implemented at a Japanese national university, targeting graduate students through diverse offerings and events aimed at fostering competitive PhD talent by bridging academia and society. Our case study showcases the background and design of this well-rounded education, reviews implementation outcomes over the past decade, and evaluates its impact on cultivating interdisciplinary talent within Japan’s higher education context. This program offers a variety of components designed to address social challenges and explore diverse career pathways across academia, industry, and government. Key initiatives include original interdisciplinary courses, project-based learning opportunities, group and individual practical activities, career development seminars, sustained career workshops, and interdisciplinary innovation retreats. These efforts not only enhance the employability of doctoral graduates and foster competitive PhD talent capable of adapting to the rapidly evolving demands of society and industry, but also strengthen connections among academia, industry, community, and government, thereby fostering a dynamic ecosystem in which knowledge creation, social innovation, and practical solutions can flourish. By combining diverse perspectives and resources, we aim to foster competitive talent and generate broader societal impact, while offering actionable insights for other HEIs.
