Just stating that there is a cultural thing that allows age gap.
Hi, I think you are confused between age gap and pedophilia.
Simple example
- 50 yo man sexually attracted to 30 yo woman (or vice versa, or same gender whatever). This is perfectly normal across the world. But in this case the age gap is quite large (20 years), which some youngsters might find it disgusting (judging from their reactions).
- 18yo teen boy sexually attracted to 12yo girl (more specifically not yet physically developed young girl). This is PEDOPHILE and for obvious reason NOT NORMAL. Note that the age gap in this case is merely 6 years!
In case you missed my point, in many culture (not only in Japan) the age gap is very well accepted and pretty normal thing in everyday life. However PEDOPHILIA is a totally different story.

It's not "having prejudice" that thinking that selling pedophilia manga in every convenient store is not a good thing.
Talk is cheap. Can you bring source of info of your allegation? I know normal hentai manga magazines that come with idol gravure photos can be easily obtained, but the one with "pedophile fetish" might not included in those. Unless you consider JK (high school girl) and shota as pedophile fetish. There are however other channels like web and doujinshi (self publishing) that could produce the more weirder fetishes like pedophilia.
The LAW in Japan is different and that might consists of loopholes for such drawing. I think as non-Japanese not living in Japan, I don't have the right to comment about their LAW. But if you have watched stuff like Mosaic Japan or Naked Director, you will understand the tricky-ness of this matter.
The Live Action Porn however is different. While some of the weird fetishes persists, they are no more than a Role Play. So the Live Action realm is totally CLEAN if you ask me. Therefore it's very IMPOSSIBLE for the mainstream drama/movie to include those elements, and furthermore, the more stricter rule has been implemented for shooting child actors some time ago. (I know because some of their dramas cynically touched on the new rule).

Your title thread is a question and I was giving what I think is part of the answer.
LoL.

It was obvious we are talking about adults
I think she just read the title. Well to be fair it was a bit confusing without the context.
