Japan is seen to have a serious problem with the sexualisation of children.

Stacey Dooley, one of BBC Three’s most popular documentary-makers fronts another powerful, hard-hitting investigation when she travels to Tokyo, Japan to look into what effect the law banning child porn has had and to see if the attitude towards the sexualisation of children has changed.
