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.
