I have been stopped by police man once. I was on my way to appointment at hotel Okura from Roppongi-1chome station. When I got close to the hotel, police man stoppend me and told me to detour. I guess that was the night eitehr the president Obama or some other VIP from the states was visiting Japan; FYI hotel Okura is located just behind the US embassy.
Glad he didn't ask me to open my bag....
My very first contact with police men was when I was in my early 20's, when I was a bit more wild than I am now.
They didn't talk to me but I went to talk to them at Kabuki-cho Koban.
I spent a night before with this American black guy I met through my friend's party a couple of years ago. He stole my credit card while I was sleeping... I got a call from credit card company asking if I used my credit card many times today when I was in a dressing room at a Ryotei, changing to Kimono. I never realized that my card was gone until I got a call. Luckily, one of the group of the night I was going to serve was bankers. I told one of them the story, asked him what I should do. He advised me what to do, what I should report to credit card company, what I should not tell to avoid paying his shopping bill.
I went to kabukicho Koban after work as advised, explained what happened.
Police man admitted that although the guy is very suspicious, I didn't see him actually opening my purse and stealing my credit card directly, they could not arrest him. They could accept a report of the loss so I didn't have to pay the bill at the end.
When I left the police station, he said "now you learnt your lesson. Don't stay overnight with a guy you don't know well."
Nope, I don't do overnight but do other things
