Let us pause for a moment to reflect on the fact that Tokyo is both the largest city (by population) and also has one of the lowest crime rates of any urban setting. Women can walk almost anywhere at any time without fear of assault, and violent crime is exceedingly rare. Same goes for Osaka, eighth largest, which is close to where I live. I recall for the first year I lived in Japan walking around with eyes on the back of my head, always partially aware of my surroundings and the people walking behind me, because that’s the natural way a lot of Americans learn to navigate public life, especially at night. I then had an epiphany: I didn’t need to do that in Japan. It was amazingly liberating.
