I don't really care about this that much but I find it funny that people are acting like Japan is some paradise for sexual freedom when harassment is a HUGE issue there. Second hand account, but my best friend, who is a woman, lives in Japan and they have train carts for women only to prevent that kind of harassment. More recently she had to report the same man twice in one week for boarding women-only cart and being a creeper.
If people want to pretend there's no relationship between the media we consume and the reality we live in, they can. However, they are wrong. Our realities are often engendered in various media. Look at the issue of diversity in casting or white washing of characters and think of all the racial tension in the USA. Think of how women's body can be sexualized to sell cars, yet people will foam at the mouth if a mother breastfeeds in public! THe connections are not always obvious or direct but that does not mean there is no relationship between the two.
Edit: Should note that my friend teaches HS and was concerned for the safety of her students as well. The very fact that she had to worry indicates that there are women-only carts and that she had to worry about a creeper points to large societal issues.
