This study aims at first reviewing the international principles and domestic law and rules for juvenile inmates' contact with their family members. The convention on the rights of the child and the U.N. rules for the protection of juveniles deprived of their liberty stress the role of family contact and family strengthening strategies in achieving successful reentry and reintegration of inmates. And the Correction law and the Regulation for treatment of juvenile inmates define family strengthening program such as letter sending, visitation in person, family reunion events, telephone service but do not give more detailed directions for juvenile inmates. Based on the notion that the role of family contact and family solidarity is more significant meaning in psychological, mental development of youthful offenders, more active family involvement is inevitable for juvenile inmate's reentry. This article also shows current status of family contact of juvenile inmates with a small survey results. Most of them appear to maintain family contact via letter, telephone, and in-person visitation but, as expected, the frequency decreases as prior criminal records and the sentencing length increase. However, regardless of frequency of family contact, juvenile inmates expect that their family helps them in reintegrating into society. In that point, we need to think offender's family as necessary resources for successful reentry of inmates.
