Anti-piracy holier-than-thou brigade, please exit stage left and find another thread to preach in.
This law is fucking stuuuuuuuuuuupid.
Not only does it immediately turn a generation of Japanese kids into criminals, it's just an awful and poor written law all around. Mostly because it was bought and paid for by JASRAC.
For those who are not familiar:
Japan does not have any real good digital distribution solution for anything. We have itunes but its mostly western music, and pretty much no options for movies/TV. We have Hulu, but its a total shell of what the American service is. It's pathetic.
All this law is is another reactionary, protectionary move by the old farts still making shit tons off of everyone else's creativity to stop digital expansion so they can still sell Japanese CD's and DVD's (that's right, not blu-rays!) at 50-100 dollars a pop. Essentially this law is a law to protect JASRAC's monopoly on copyrighted media.
Not to mention the law makes no fucking sense.
Example: It is totally legal now to download a TV show after it airs, as long as it isn't on sale somewhere in Japan. But once it goes on sale, you can get arrested for downloading.
Meanwhile, downloading child porn is totally legal here (outside of Kyoto).
For those wondering about what will happen to Japanese media outside of Japan: China.
