Hard to say what the new law means from here. If someone can post the actual provisions of the new law that are worrisome, it might help.
It's late and I don't want to look it up, but it wasn't the copyright infringement for me, though the notion of jail time for downloading American/Canadian/British TV that you have no legal access to in Japan is pretty uncomfortable. It's that the main point of the law is planning a crime is a crime. That's nutty thought-police stuff. Japan is a fan of vague laws. What does planning entail? If you want a real law, it would define things, like procuring resources, making deals, establishing things and so on. But it's vague, it's planning crimes.
There's a law in Japan that foreigners can't affect the political system or they will be deported (I have the article about it, by a foreign law professor in
Kyoto, can find it if need be). It's basically never used, but if the country needs to get you out, it's a flimsy, vaguely worded way to do so (this post may be used as evidence if the country desires to prove I'm an unwanted immigrant). Likewise, this 'planning a crime' thing is way too similar. There's a reason why Japan had its largest protests in decades over it, why world rights groups contested it, and why the government steamrolled it through. It's garbage, and just a way for the government to keep citizens in line. I'm not in favor of crime, but there's crime and there's CRIME.
This bill is to help police spy on domestic, minor crimes, and was passed under the blanket term "anti-terrorism". That's scary. Japan's a great, peaceful, safe country. I don't want it a police state. They included mountain mushroom picking in the law. Do you think mountain mushroom picking is in any way a source of terrorism funding?
