From later '70s, a view about the Japanese urban life has generated and young people believe that the city, especially Tokyo, never sleeps.
But, it was only an illusion. Even now, over 90% of the urbanites sleep in midnight. So, what made the misunderstanding? By checking various statistics, we can attribute this illusion to the tremendous increase of the "Famirii Resutoran(family restaurants) " and the "Konbiniensu Sutoa (convenience stores) ".
There is no big change of urban life time-tables in these ten years. Rather, the modern consciouness of time serving the industrial development has been amplified. Some deviant behaviors committed by boys are well interpreted as the consequence of the strain between the different values about the time.
On the other hand, young people tend to use some media (eg. telephons, personal computers, video recorders, and so on) and stay up late. The important transformation of the consciousness of liniar time is generated in these areas.
