I think you might never seen Jap porn movie or know anything about Jap porn industry. if you said 70% from US and 29% from Jap that's more acceptable. mostly I only watch Jap porn though. I dont like those blonde porn star.
90% of porn comes from the U.S.!? I don't think that's true. The U.S. is less than 5% of the worlds population. US World 300,000,000/90 = 6,300,000,000/10 3,333,333 = 630,000,000 630,000,000/3,333,333 = 189 That would mean people in the U.S. are 189 times more likely to make porn than the rest of the world.
so what, lots of people in Africa, South America, China doing it instead no wait, forgot about Greenland, a hotbed for the Eskimo porn.
