EJU Mathematics Course 1 case studies
EJU Mathematics Course 1 · Put your knowledge to work in context.
The Examination for Japanese University Admission for International Students (EJU) is administered by JASSO as a written examination used by Japanese universities and other schools for international applicants. The Mathematics component is offered as Course 1, aimed at candidates who need a mathematics score for admission but whose intended field does not demand the more advanced Course 2 syllabus. The exam is delivered in Japanese or English, and the Mathematics paper is a written test sat alongside other EJU subjects selected by the candidate. JASSO publishes an official Mathematics syllabus, and a revised syllabus applies to the questions of the 2026 EJU 1st Session, so candidates should study against the version that matches their test date. The EJU Mathematics Course 1 case studies are 5 cases and about 2,122 words.
