There are a LOT of police in Tokyo. I mean a LOT. Seems like every few blocks you run into a group of them. You don’t see many police cars and the one time that I was flagged down, it was the police officer stepping onto the road.
Perhaps one of the reasons why Tokyo is so safe (although I think it is more cultural, than due to police presence).
I am always driving past these fellows and I have yet to figure out what they do. They just stare at the passing cars, sometimes a whistle in their mouth just waiting to be blown. At other times holding their walkie-talkie and watching the traffic drive by.
Always staring. Never moving. I don’t understand. (smile)
