Public elementary and middle schools are closed on
national holidays, Saturdays, and Sundays.
Japanese schools have three semesters, separated by vacations.
At most schools, summer
vacation covers the 40-odd days from July 20 to August 31; winter
and spring
vacation both last around 10 days, from December 26 to around January
6 and March 25 to around April 5, respectively. The new
school year starts in April, at the end of spring vacation.
