Just to let you know, there is a lot of confusion about why some Japanese porn is censored and some isn't. It's quite simple. Japanese porn produced for distribution in JAPAN is censored -- it always has been.

Japanese porn produced for distribution OVERSEAS in areas where there is no censorship is not censored.

Nowadays, with the Internet, a lot of Japanese distribution porn is viewed overseas, while a lot of overseas distribution porn is easily accessible in Japan.

The Japanese censorship laws are dying slowly, because it is obvious to anyone with a brain that the Internet makes them obsolete -- but they are still on the books for now. Don't worry however, the amount of porn being produced for overseas distribution is growing at a rapid pace, and there will be plenty of high quality, uncensored, Japanese porn for you to enjoy in the future.
