Japan's copyright law's make what Disney pushes for seem fair and reasonable. Copyrights last for 70 years and there's no fair use (but somehow there's shelves full of hentai parodies of current manga). Donkey Kong 1981 will be legally protected until 2051 and I'm willing to bet they'll alter the law to protect it even longer.

All of these laws can be completely ignored however, if you live in China and DGAF.
