Probation for juveniles is divided into that under protective measures and that under criminal disposition.
  Probation under protective measures is for: (i) those who are placed under probation by a decision of the family court ( juvenile probationers), and (ii) those who were allowed to be provisionally discharged by a decision of the Regional Parole Boards after they were committed to juvenile training schools by a decision of the family court ( juvenile parolees). The Regional Parole Boards permit release on parole from a juvenile training school when juveniles have reached the highest grade in treatment and it is deemed appropriate to place them under probationary supervision for their improvement and rehabilitation, or when their performance has improved such that it is deemed particularly necessary for their improvement and rehabilitation to place them under probationary supervision, though they have not reached the highest grade in treatment. Viewing the status of permission by Regional Parole Boards in response to requests for release on parole, such requests were hardly ever rejected by Regional Parole Boards. In 2002, the number of requests accepted was 5,852 (an increase of 43 persons from the previous year), and the number of requests rejected was only 1 (same as the previous year) (see Appendix 2-12 ).
  Probation under criminal dispositions is for: (iii) those for whom parole was allowed by a decision of the Regional Parole Board after they have served an imprisonment without suspension of execution of sentence (there exists an a indeterminate sentence as an institution related to the term of sentence which is particular to juveniles; see Chapter 2, Section 1 ) ( juvenile parolees from prisons), and (iv) those who were given a suspended sentence and placed under probationary supervision ( juveniles granted suspension of execution of sentence with probationary supervision). The number of juvenile parolees under 20 who were newly accepted from prisons in 2002 was 2. The number of juvenile prisoners granted parole from prisons who were sentenced to an indeterminate sentence (including those who reached 20 years of age after sentencing) was 26, and the number rejected was 3. Also, the number of juveniles under 20 newly accepted for suspension of execution of sentence with probationary supervision was 27 (Source: Annual Report of Statistics on Rehabilitation).
  Regarding probationary supervision for juveniles, the number of cases for (iii) and (iv) has been small as mentioned above. Therefore, this section covers probationary supervision of (i) juvenile probationers and (ii) juvenile parolees.
