The types of probationary supervision for juveniles target juveniles who have been placed under protective measures, and juveniles who have received criminal dispositions. Probation that targets juveniles who have been placed under protective measures is for: [1] those who are put on probation, which is one of the protective measures arising from the decision of the family courts (juveniles probationers), and [2] those who were allowed to be tentatively discharged due to the Regional Parole Boards after they were committed to juvenile training schools, which is one of the protective measures arising from the decision of the family courts (parolees from juvenile training schools). Of these, 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 in society for their improvement and rehabilitation. It may also be permitted when their performance has improved such that it is deemed particularly necessary to place them under probationary supervision, even if they have not reached the highest grade in treatment. The requests for release on parole were hardly ever rejected by the Regional Parole Boards, the number of requests accepted was 5,809 (7.3% up from the previous year), and the number of requests rejected was 1 (4 in the previous year) in 2001 (see Appendix 2-12 ).
  Probationary supervision, which is enforced for juveniles who have received criminal dispositions, is for: [3] those for whom parole was allowed (juvenile parolees from prisons) as a result of the decision of the Regional Parole Boards after they have served a prison sentence (as for the type of prison sentences, there exists an a indeterminate sentence as an institution particular to juveniles), and [4] those who are put on probationary supervision by being given a suspended sentence (juveniles granted suspension of execution of sentence with probationary supervision).
  The number of juvenile parolees under 20 newly accepted from prisons in 2001 was 0 (2 in the previous year). The number of convicted juveniles granted parole from prisons who were sentenced to an indeterminate sentence (including those who reached 20 years of age after sentencing) was 18, and the number rejected was 0. Also, the number of juveniles under 20 newly accepted for suspension of execution of sentence with probationary supervision was 21 (21 in the previous year) (Source: Annual Report of Statistics on Rehabilitation).
  In this section, regarding probationary supervision for juveniles, the number of cases for [3] and has been small for a long period of time. Therefore, this section covers probationary supervision of juvenile probationers [1] and parolees from juvenile training schools [2].
