The Japanese do not have janitors in their schools. I hear the children are responsible for cleaning their own schools.

I once worked at a Y camp cleaning cabins where we had a whole group of Japanese visit for a week. I didn't have to clean their rooms at all for the time they were there.

They had made their own beds and washed their sinks and apparently their own toilets, too. They hung all their towels neatly. I even suspected they swept the floors. I just switched out their towels and washcloths for them and had a good break that week .
