After completely reading all of this article and the ones linked to this subject this sounds more like it only applies to adult animes and mangas or ones that go WAY over the border more than other animes and mangas that can hurt minors the ways listed in the article.
It does not sound even close to the end of late night anime to me, it is more like a ban on any type of anime or manga that has to do with pedophilia or any explicit material that is considered taboo or immoral.
But, since the bill was too vague to begin with, no one knew if they were talking about all manga and anime or just anything that is believed to affect minors negatively. I am going to do some more re-reading later still, because in two of the articles it sounded like that the ones involved with the bill's creation are saying that they are trying to make sure minors do not get ahold of any type of explicit content after they recieved the critical response from manga and anime artists.
