Since its introduction three years ago, Japan's correctional program for sex offenders, modeled after Canada's system, has made great strides, a leading expert on rehabilitation from Ontario says.
Still, the country must develop a stronger parole system if it wants to reduce the risk of recidivism, said William Marshall, professor emeritus of psychology and psychiatry at Queen's University in Kingston, Ontario.
In fact, providing good supervision is also cost-effective compared with measures like the electronic monitoring of sex offenders, according to Marshall.
