What a disgusting man!  He embarrasses all of us. I have seen a program on Soko ga Shiritai (thank you KIKU) on the Japanese penal system. It is hard time, but also very effective. Their "counseling" is designed to inspire shame and empathy for the victims. They also work to really rehabilitate to truly reintegrate back into society. But, foreigners are segregated, and probably not given the same treatment. A wife and child in Japan will not keep him from being deported if he serves time in Japan as well.
