When do students in japan have spring break?

Answer 1

Primary and secondary students have spring break (which is the break between academic years) from some time in late March to some time in early April.

University students generally begin classes in the second week of April; the spring break can begin as early as late January.

Answer 2

Yes, Japanese schools have summer break.

But it is not as long as American schools. It usually only lasts for about a month or less than a month.
