Mikagi-sama
From what I know:
Semester 1 starts in April
Semester 2 starts in September
They go to school for July, and get August off.
They go to school every second saturday during school.
Their schooling is longer than that off the U.S. and Canada.
They have to take entrance exams into middle school (I think?), high school, and university.
It's really tough.
They have school uniforms.
And that is the basics.
