Tuition is 535,800 JPY per year.

The Astronomical Science Program, offered as a five-year doctoral program at The Graduate University for Advanced Studies, SOKENDAI, is conducted in English, with admission each October, based at the university's Tokyo location. SOKENDAI was established in 1988 to train first-class researchers through doctoral course programs built around the research environment of Japan's Inter-University Research Institutes. The program covers astronomy and astrophysics, including topics such as observational astronomy, stellar and galactic physics, and the analysis of data from ground-based and space telescopes. Tokyo hosts major Japanese astronomical research institutions, giving doctoral candidates access to observational data, telescope facilities, and computational resources used in current astronomical research. The five-year format takes students from foundational coursework in physics and astronomy through to independent dissertation research on a specific astronomical question, and applicants are required to submit a GRE Subject Test score report in Physics as part of admission, reflecting the strong physics foundation the program expects. Students in astronomical science programs typically work on topics such as the structure and evolution of stars and galaxies, the analysis of telescope and satellite data, and theoretical models of astrophysical phenomena. Graduates commonly pursue research scientist roles at observatories and space agencies, academic positions at universities, and postdoctoral research positions extending their dissertation specialization. Being based in Tokyo places doctoral students within a major research hub connected to Japan's national astronomical institutions. With a single annual intake each October, applicants plan around one entry point per year for the five-year doctoral track. Instruction delivered in English, combined with a required English proficiency test and a GRE Physics subject score, makes the program accessible to internationally trained applicants in physics and astronomy without first needing Japanese language proficiency.
