Have you cleaned your classroom after school on your own?
You can ask this question to Japanese people. They will answer "Yes. Haven't you?"
In Japan, most schools have cleaning period after school.
It is for about half an hour. Each group cleans various areas on a daily or weekly shift.
They clean their own classrooms, toilet rooms, halls, gym, even faculty room!
Students sweep and wipe the floors, dust, vaccum and so on.
If you feel Japan is a clean and organised county, it may be because Japanese people spend
lots of times cleaning from their young age.
