Many Japanese otakus worried about the influence of Trans-Pacific Partnership,
because it may dismisses Dojins if the TPP make Japan join to the new copyright law.
Now, the copy right law is not a crime requiring a formal complaint from the non victim for prosecution.
If the law change, anyone can take legal action against the Doujin maker and they will distinct.
In the lastest conference about the TPP,
it was announce that the copyright law doesn't change,
so Dojins are saved.
