Are there other Hentai, Mangas or Doujin turned into Live Action JAV versions like this?

This Jav label makes a lot of those adaptations.

In JAVlibrary you can search by tag "Original Collaboration":

I'd only just watch this two great movies. The only downside is that in both cases they change some scenes from the original material.
