Yes, some Japanese production companies have their uncensored films shared here, others not. The censoring is a major annoyance for me. There must be a way for companies to distribute or share their UNcensored videos they make there in Japan. I presume they're uncensored for viewing in Japan?
The censorship in Japan has been going on since porn was introduced, it's a law there. Obviously there are ways to get around it and I'm also seeing more minimal blurring so there's not much left to the imagination.
I have no idea why some Japanese porn is censored, some not. Obviously, it's done in the editing process. I'm guessing it's not censored for viewing in Japan, just when it's exported. Bah humbug!
