Good-conduct measures are implemented when the behavior of a probationer or parolee has become stable during the period of supervision and he/she has come to be considered unlikely to commit repeat offenses. There are two types of measures as follows: an indeterminate sentence parolee who has served his/her minimum term is granted termination of indeterminate sentence as if he/she has completed his/her sentence; an offender given suspension of execution of sentence with probationary supervision is granted provisional discharge from probationary supervision.
  In 2005, 491 offenders given suspension of execution of sentence with probationary supervision were granted provisional discharge from supervision, and one parolee was granted termination of indeterminate sentence (Source: Annual Report of Statistics on Rehabilitation).

  Bad-conduct measures as follows are taken when a probationer or parolee under supervision has violated the conditions of supervision or committed offenses. A subject parolee is imprisoned again in a penal institution by way of revocation of parole, and an offender given suspension of execution of sentence with probationary supervision may receive revocation of suspension of execution of sentence. A parolee whose whereabouts has become unknown is subject to suspension of parole and the progress of the sentence is interrupted. In 2005, 466 were subject to suspension of parole (Source: Annual Report of Statistics on Rehabilitation).
  Where a person in question fails to reside in a fixed abode or there are sufficient reasons to suspect that he/she has violated the conditions of supervision, and he/she fails or would fail to respond when summoned by a probation office director, he/she is apprehended under a warrant of arrest issued by a judge. Following the decision to commence the examination on a bad-conduct measure, he/she is detained in an appropriate institution for a fixed term. In 2005, including juveniles, 253 probationers and parolees were apprehended and 213 were detained in this manner (Source: Annual Report of Statistics on Rehabilitation).
