I'd love to see them do an experiment that compressed hours per day instead of days per week. I used to do consulting around the world for an American software company and Japan is the only place where I saw people straight up fall asleep in meetings. When I asked my hosts about this phenomenon they thought for awhile and then attributed it to a culture of "presence", which was basically a layered phenomenon of trying to be in the office before (and/or stay later than) other workers in your hierarchy. Seems this was a more obvious thing to measure than productivity since your boss notices precisely when you come in or leave. Tack on long commute times and pretty soon the workday has expanded to the point where getting enough sleep is physically impossible.
