Chuugakkou is the Japanese term for "junior high school," which typically serves students aged 12 to 15. It is the educational stage that follows shougakkou (elementary school) and precedes koukou (high school). In Japan, junior high school usually lasts for three years and focuses on a broad curriculum, including subjects like mathematics, science, social studies, and languages. Students in chuugakkou often participate in various extracurricular activities, such as sports, music, and clubs, which help develop teamwork and social skills. Attendance is generally mandatory, and many students prepare for entrance exams to koukou during their final year.
