Another one is public transport. I have been groped a few times during peak transit time in the BART. It was incredibly unpleasant and ruined the whole week for me. It’s creepy and the violation of personal space feels like rape.
Well, that seems to be the policy solution that Japan picked. In addition to the cultural development of well-intentioned men holding their hands in the air on crowded mass-transit to prove their good intentions, and thus throwing suspicion on men who don't do the same.
Though it's worth noting that mass-transit in Japan is frequently packed so tight that if you don't have your hands up, you're literally touching someone else anyway. Not hard to see how that amplifies the molestation problem significantly in Japan even if other countries (presumably) have the same % of men with a propensity towards such actions.
