Since prerequisites and program details differ, you must visit Gunma University's official website and specifically the Graduate School or International Student Admissions pages to determine the precise post-graduate application requirements for international students. To find comprehensive information on eligibility, necessary documents, application processes, and deadlines, look for a "Admissions" section and a "Japanese Government (MEXT) Scholarship" or comparable international programs. These documents may include academic records, language proficiency scores, and recommendation letters.
