The Japanese educational system underwent reform after World War II. It now consists of 6 years of elementary school, 3 years of junior high school, 3 years of senior high school, and 4 years of university. Elementary and junior high education is compulsory for 9 years. Enrollment rates are near 100% for compulsory education and over 96% for high school nationwide. About 46% of high school graduates go on to university. The Ministry of Education closely supervises education nationwide to maintain high standards. The national curriculum includes subjects like Japanese, math, science, and English. High schools can be academic or vocational. The school year runs from April to March.
