Great post. The place of rest in our lives is really important. I think there are some un-noticed reasons why some people over work themselves, some could be problems at home, and others could be threat of a sack,etc.I believe that there should be a body set up, to handle the issues around over working. Those who need psychological help will be attended to, and those who are intimidated into overworking can also be helped legally. This is an issue that requires serious attention, especially by the government, not just in Japan alone but in all countries of the world
