Yeah, so I can't find anything backing this up. I'm going to have to search in Japanese on the Agency website, so it might take a while. If anyone who speaks Japanese wants to try, I encourage them. Point is, Japan's been saying this for a longass time. I'll admit, I feel guilty, but I barely have the cash to buy even one manga series
Only PR announcement in December is about a fiscal grant, so unless they announced it on TV or months ago and the website you linked is only JUST talking about it (and even then, I've seen nothing on other websites talking about any sort of 2 year jail sentence or fine; obviously you can be arrested for this, but I've seen no proposal of two years anywhere), I wouldn't worry just yet.
Anyone know what's going to happen to this site due to this?
