Here’s what happens when there are too many articles like the one posted below. The Manganews Forum translates an article from the Japanese press about Osaka prefecture requiring “adult” manga to be shrink-wrapped:
In order to raise the effectiveness of the Fostering Healthy Young People Regulation, the prefecture has imposed a duty of individual shrink-wrapping to adult magazines and alike. The prefecture has also made plans to tighten its measure, such as specifying harmful books, which includes shoujo manga with excessive obscene depiction.

Shoujo manga with obscene depictions will be submitted to the Prefecture’s Youth Healthy Training Council, where it will be determined whether the title is consider a “harmful book” and to be shrink-wrapped.
