...and even bestiality!
What a sacrilege, someone need Jesus in his heart
Now getting serious, the japanese censorship law is enforced on distribution and production, consuming uncensored porn is "fine" but selling it will get them in trouble. And as you pointed out, a deal with another external company would make viable the distribution of those uncensored videos, which are mostly stored and enjoyed by a few ones, but it's up to the companies what to do with their productions.
Also, censored porn is from Japan, Korea only allows softcore, while China has more strict laws wherein possession of any kind of obscene content would allow for 3 years in prison... Asia has many countries, each with their own rules on pornography. And the chinese guy story has nothing to do with censorship.
