A comment on list accuracy
As I'm not the original author I can't guarantee accuracy. I can say I'm highly suspicious of why most large Japanese AV production companies persist with such wide and obscure mosaic "screens", when Japanese magazines are permitted far more detail in their nude photography and video review photos (blanket restrictions on the showing of pubic hair in the general media were eased in 1994, and magazines have been slowly but surely showing more with each passing year since - see Apple Tsushin magazine and you'll see just how much they can get away with). Even some uncensored videos available in the U.S. of actresses like Shiori Fujitani, Rina Kitahara and Yu Kawaii show blatant faking of sex and ejaculation. I'm sure that many of the more popular AV actresses would not become involved in the industry if the sex was genuine, so to protect their profits the mainstream AV companies continue with the practice of ensuring there is no certain way of knowing if the sex is genuine or not.
Generally speaking, the smaller independent companies ("Indies") are less determined to obscure detail and consequently are more likely to feature genuine action. The actresses though are usually not as popular as those featured in the mainstream companies' videos, or are actresses whose 15 minutes of fame are almost up.
