Well the schedules were fine for me.When I was in highschool,I go to school at 7:00 am(flag ceremony and homeroom but classes start at 8) and our classes ended at 5:00pm though sometimes I arrive at home at past six since I'm a member of the student gov and because of other activities.I think there's really not much difference between our schedules here and in jap though we can go home at lunch(not like them).
