Ok, mom, firstly, you need to understand that this isn't porn, all right? It's called "hentai". Yes, that's a Japanese phrase, I'm learning Japanese from these videos. Before I get to the part about learning Japanese, though, let me first comment on the cultural implications of hentai. After the second world war, which Japan lost after the nuclear bombs were dropped on Hiroshima and Nagasaki, the entire country underwent a period of self-reflection and soul-searching. They wanted to understand how events led to the rest of the world responding with such devastating atomic attacks. This led to a strong antipathy towards war-mongering and international aggression. You may have heard about how the Japanese constitution doesn't allow the country to have an active military. Same idea. A lot of post-war Japanese culture is a reflection of such attitudes.
