The JSPS–UNU Postdoctoral Fellowship Programme 2026 offers early-career researchers a prestigious opportunity to conduct advanced, sustainability-focused research in Japan. Organized by the United Nations University Institute for the Advanced Study of Sustainability (UNU-IAS) in partnership with the Japan Society for the Promotion of Science (JSPS), this fellowship is designed for scholars aiming to make a global impact through interdisciplinary research in areas such as climate change governance, biodiversity, water and resource management, and innovation in education.

Fellows will spend up to 24 months at a Japanese university or research institution, working under the supervision of a host researcher and in cooperation with UNU-IAS in Tokyo. The programme emphasizes policy relevance, interdisciplinary approaches, and research with global impact, particularly supporting scholars from the developing world.
