You don't get the feeling insomnia is a problem in Japan. As a matter of fact, in Japan, a nation plagued by sleep, I'd say most people have the opposite -- "ainmosni," or the overability to sleep. In fact, one of the most common expressions in Japan is "Tsukareta!" (I'm tired!).
The two reasons for this are surely overwork and undersleep. Many Japanese work more than 50 hours per week. Thus, the Japanese are forced to get in their sleep time on the trains, at their desks and during office meetings.
I say: Bring sleep to the people! To do this, I propose the following changes to the Japanese system.
