Policing For Prevention Of Juvenile Delinquency In Japan

I will analyze the development of policing for prevention of juvenile delinquency after the World War II.  Immediately after the war the Japanese police system was democratized.  However, the police did not have resources enough to carry out the activities for prevention of juvenile delinquency.  With the recovery of economic conditions the police established the system to prevent juvenile delinquency.  Since then the police have carried out the net-widening of their activities for the prevention of juvenile delinquency.  I will explain how the net-widening has been carried out.
