A Chinese man learned Japanese thanks to adult films (3 photos + 1 video)
Here's some good advice on how to learn a foreign language "from scratch" to a pretty decent level. Even the owl from Duolingo is nervously smoking on the sidelines. 
The guy lived in China his whole life, but the local girls didn't attract him, and he became addicted to watching pornographic films with Japanese people. And he got so carried away with it that at some point he realized that he understood perfectly well what they were talking about there. 
I decided to check if this was true, and unexpectedly passed the exam, and not just any old way, but at level N2, which allows foreigners to study at technical schools and even at some universities in Japan.
However, to reach this level, he had to watch 4,545 pornographic films, which in total took 6,700 hours.
According to the Ministry of Education, Culture, Sports, Science and Technology of Japan, they claim that to reach level N2, you need to regularly study Japanese and devote more than 600-900 hours to it.
Sora Aoi, Kana Momonogi
So it is not surprising that the lover of Japanese "teachers" passed the exams with flying colors, because he approached the matter responsibly, although not on purpose. He calls himself "the last gentleman of Asia" and sincerely thanks the hard-working actresses of this difficult genre - Sora Aoi, Aoi Tsukasa, Kana Momonogi, Rei Honjo.
