A Korean singer and a comedian examine the adult entertainment industry in Japan. I don't think humor translates either across cultures or across time, so some of the jokes in this didn't really land. The good thing about the documentary was that it did explore a lot of these areas of Japanese culture that might be a little bit fascinating to people from the outside, and they do it in a very Korean way. They go to a sex shop, and it was just like a typical sex shop, I'd say it was much bigger and more like a sex grocery store, so that was a little bit crazy. Then they interviewed three adult actresses about their jobs, and they made a very interesting point which is in the west we have a tendency to make a connection between violence and pornography where people make the erroneous claim that pornography increases violence against women or pornography itself is an act of violence against women, but they made the claim, and probably it's also equally untrue, but they made the claim that pornography is good because it allows men to release their urges, so there's less sexual crime. Then they interview a really famous adult entertainment actor, then they go to this a company which produces toys for men called Tanga. The next episode was about a host club. It's basically where women can go and have some theoretically attractive companion. Then they do a lacklustre interview with "typical" Japanese people. I thought it was an interesting documentary if you're interested in Korea or Japan-this is a two for one.
