Of course this video was shot in the afternoon when the carriage was no longer women only.
And somehow segregation and racism in America bears no resemblance whatsoever to Japanese men being asked not to use particular train carriages at certain times of the day. Because women are being assaulted I think it's perfectly reasonable.
But I know the video was done for comedic effect.
The chikans on trains is weird and shocking and just a bit sad really. So is having women-only floors in hotels.
It's at least partially due to a somewhat warped view of women and sex.
And an un-willingness to break the pervs fingers on the part of the woman. (what would probably happen in UK) and an unwillingness to cause a scene.
But it's not unique to Japan. It Italy women are likely to have their bottoms pinched and it happens in Paris as well. And the statistics for assaults reported in the UK is pretty appalling, women might be safe from being grouped on a train but not necessarily safe walking down a street alone at night.
There's also the flip side to the situation where a couple ran a scam to accuse men of groping the girl to shake him down for several tens of thousand yen.
And there's the situation of false accusations, or mistaken accusations. I don't think you ever want to get caught up in the Japanese justice system. So much so apparently there's a call for men only carriages that so far has been ignored by the train companies.
