Yeh everyone is saying this is amazing, which it is, but I really wish they would employ professional cleaners to come in once a week or something. The commenters here would NOT believe the state some japanese schools are after 20-25 years. They are falling to pieces, with dirt/spider webs and dust the norm, because you're relying on children to do all of the cleaning. The windows (apart from the ground floor) are caked in dirt because it would be too dangerous for the kids to clean them.
