It really isn’t even all that long ago when finding uncensored Japanese porn was an absolute impossibility. Japanese laws was so strict, honestly I think they are still so strict but people have now explored workarounds.
I don’t know that anything has changed in their laws and if it is indeed still the same it means that all porn produced and released in Japan has to have the genitals pixelated.
I know some cool cats then decided to ‘import’ Japanese pornstars and produce and release Japanese porn outside of Japan and thereby bypassing this law.
I have to wonder if something has changed though because it’s one this to get female pornstars to other countries but I wouldn’t expect anyone to get Japanese guys too purely so that it is a Japanese guy fucking a Japanese girl. It’s just not how people in porn roll in my experience.
I have a feeling something may have changed in the law even if I just look at how much more uncensored Japanese porn there is these days and this is one of the great sites. You can get a 51% off discount to AV Idolz with this link.
