3 Characteristics of Newly Admitted Juveniles

(1)Age at time of admission
  Fig. III-41 shows trends in the ratios of juveniles newly admitted since 1990,by age group. Although senior juveniles traditionally had the largest share, the ratio of intermediate juveniles has been rising in recent years and slightly exceeded that of senior juveniles in1999.
  As regards age at the time of admission by gender,17-year-olds had the largest share in the number of males newly admitted in1999(24.8%), followed by18-year-olds(22.9%),19years olds(20.5%)and16-year-olds(18.3%). On the other hand,16-year-olds were most prevalent among females(23.0%), followed by17-year-olds(20.6%),18-year-olds(17.6%)and19-year-olds(16.8%)(see Appendix III-14 ).

(2) Foreign juveniles
  Of those newly admitted to juvenile training schools in1999,23juveniles(all males)were placed in the living guidance course(G2)as foreign nationals who need treatment programs different from Japanese nationals(hereinafter referred to as"foreign juveniles"). By nationality, Brazilians(19)had the largest share. By age,19-year-olds accounted for the largest share(6), followed by17-and18-year-olds(5each)and15-year-olds(4). By offense, larceny was most prevalent(15), followed by robbery(6), and bodily injury and Stimulant Drug Control Law violations(1each)(source:Annual Report of Statistics on Correction).
  Traditionally, foreign juveniles used to be admitted to Kurihama Juvenile Training School(males)or Haruna Female Juvenile Training School. Since December1999,however, they have been admitted to juvenile training schools of the regional correction headquarters within the jurisdiction of the family courts that adjudicated the relevant cases, with the exception of those who require special consideration due to difficulty in understanding guidance in Japanese, for example. (Females are admitted to one of the three juvenile training schools designated as broad region schools. )In these schools, guidance for learning Japanese is provided according to the needs of individual foreign juveniles, along with guidance on problematic behavior and future prospects including repatriation, among others.
(3) Categories of offense
  The ratios of juveniles newly admitted in1989,1994and1999by offense are shown in Fig. III-42. The ratio of larceny was largest in each of the three years, but has been on a downward trend. The ratios of bodily injury/assault, robbery and extortion are on the rise.

The number admitted for homicide has remained within the20range, except in1993,1994and1998. The number admitted for robbery increased substantially in1996and1997,but declined in1998and1999. By age group, intermediate juveniles accounted for almost half of those admitted for robbery, except in1994. The number admitted for bodily injury was in an upward trend from1995but dropped slightly in1999. By age group, the ratios of junior and senior juveniles have been on the rise, at the expense of intermediate juveniles.
