I think it's bit too much, once a while neighborhood or school cleaning makes sense but it shouldn't be part of a typical school day.

Along the same lines, lack of trash cans in Japanese streets and classrooms is also a source of frustration, most people have to carry their trash in their pockets which is weird.

I disagree. Being taught to clean up after yourself and to share in the clean up is more essential than learning about igneous rocks and Magna Carta. So many women (esp.) are miserable in their marriages because their husbands have never learnt to keep their home clean.
