In Japan Incest isnt a Crime..

Incest is against the rules in all societies, but you know what they say; if it didn't happen, there would be no need for rules against it. In Japan, the Civil Code restricts incest marriages, but incest is not a crime. Incest law was abolished in 1881. There is currently such a taboo on talking about sexual molestation of children that current official figures report only a few hundred cases.
In the late 1980s and early 1990s there was a media panic in Japan about the prevalence of mother-son incest. Mama Love (or Kinshinsokan Monogatari) Clubs began to be opened for men eager to pay large amounts of money to see older women having sex with young men that were promoted as being their son. Women started to come in bringing their own sons or other young boys to watch. Now most of these 'Mama' clubs have some type of amateur night for mother/son couples.
The situation is blamed on the excessive motherly love Japanese women shower on their sons; idolizing them and viewing their sons as the greatest object of their hopes, dreams, and love, and Japan's obsessive exam culture.
A boy's whole future can depend on the senior high school he gets into. The mothers get into a psychological condition where they're aware that sexual urges can stop their children from studying and feel that they are the best option for countering the craving. Some mothers will do anything to make sure their junior high school sons pass the all determining entrance exams. Studies show that almost 80% of Japanese men report they have had some form of sexual contact with their mothers with most of the sexual contact between mother and son beginning at a very early age. A boys childhood in contemporary Japan, although somewhat more Western than that of other Eastern nations, still includes masturbation by mothers "to put them to sleep." Parents often have intercourse with their children in the same bed with them, and "co-sleeping," with mothers physically embracing the child, routinely continues until the boy is ten or fifteen. One recent Japanese study found sons sleeping with their mothers over 20 percent of the time after age 16. A recent sex survey reported "hot lines" of sexual abuse saying that mother-son incest in almost a third of the calls, the mother saying to her teenage son, "It's not good to do it alone. Your IQ becomes lower. I will help you, " or "You cannot study if you cannot have sex. You may use my body," or "I don't want you to get into trouble with a girl. Have sex with me instead."
