JAV stands for Japanese Adult videos. Or in other words Japanese porn. Another common acronym is AV.
In short, Japan has anti-obscenity laws that do get enforced. Namely article 175 of Japanese law which takes care of obscenity. The law and interpretation has changed over the years but nowadays is still in full-force and studios pay attention to it.
This might sound as a contradiction for Japa, which has some of the most pretty liberal laws regarding porn in all of Asia. Compared to many other countries in Asia and around the world in which porn is outright banned.
But, let this serve as an example:
And so the situation in 2018 is that we have a considerable thick censorship, much thick than pre-2014.
In short, yeah. But if you are nitpicky like me you could say no and be right about it.
Because if the studio is not Japanese and the movies are not distributed in Japan is not JAV. Regardless of the main actress or the staff were Japanese nationals.
The way I see it:
Physical copies can be purchased at Amazon.co.jp. (However, Amazon Japan don’t ship adult goods outside Japan).
And other websites such as Square plus or cdjapan.
I successfully purchased in all these websites listed above in the past. So yes, they are legit and reliable.
About the male actors and directors, there is little information out there.
Information in 4 letters and 3 numbers.
JAV films get assigned a code by the studio to uniquely identify it. It’s very rare (although it happened) that 2 movies will share the same code. Hence we could say that every JAV movie has its unique code.
JAV codes consist of a few letters and help to identify the maker and the fetish if such maker focuses in a fetish. The product code gets to be printed on the side of a DVD cover and in the back of the box. Mathematics leave no room for mistake, so it’s a brilliant system and the fastest and accurate way of telling other what movie you talking about.
