The PhD in Materials Science at Yokohama National University is a doctoral research program offered through the Graduate School of Engineering Science within the *Department of Mechanical Engineering, Materials Science, and Ocean Engineering. This program emphasizes cutting‑edge research in materials science, including advanced functional and structural materials, materials mechanics and processing, and energy‑related materials, often in collaboration with research institutions such as the National Institute for Materials Science (NIMS) through the YNU‑NIMS Joint Graduate School Program. Doctoral candidates work under joint supervision of university faculty and leading researchers, conduct independent research, take necessary advanced courses, and must complete and defend a doctoral thesis to demonstrate original scientific contribution. The program prepares students for careers in research and development, academia, and industry in areas where advanced materials innovation is critical. 

NOTE: The university may have additional program-specific eligibility requirements.
It is recommended to verify these on the official university website.
