Juken: Japanese School Entrance Exams Explained

Juken (受験) is the Japanese term for entrance examinations that determine admission to schools at every level — from private elementary through university. The most intense periods are chugaku juken (middle school entrance, typically age 12), koko juken (high school entrance, age 15), and daigaku juken (university entrance, age 18). Each exam tests Japanese language, mathematics, English, science, and social studies, with content and difficulty varying by school selectivity.

Preparation often begins years in advance. Many children attend juku (cram schools) after regular school hours, starting as early as elementary grades for competitive middle-school exams. Juku provide structured curricula, mock exams, and interview coaching. Families also use correspondence courses, private tutors, and commercial workbooks. The timeline is rigid: application windows, exam dates, and results announcements follow a national calendar, so missing a deadline means waiting a full year.

Worked example — typical middle-school maths question: A rectangle's length is 3 cm longer than its width. Its perimeter is 30 cm. Find the area. Solution: Let width = w cm, then length = w + 3 cm. Perimeter = 2(w + w + 3) = 30 → 4w + 6 = 30 → 4w = 24 → w = 6. Length = 9 cm. Area = 6 × 9 = 54 cm². The method: set up an equation from the perimeter formula, solve for the unknown, then compute the requested quantity.
