Good to see you're writing too.
It's the same here in Japan. People keep to themselves when there's some kind of disturbance. Nobody wants to get involved. Fortunately, the police here are completely different. I know a guy here who has had several encounters with the police after getting shitfaced and causing trouble. Every time, the police have been very tolerant of his behavior, simply getting in touch with his wife and escorting him home. Except for the most recent incident I'm aware of, when he was drunk on the train and freaked out because the train was stopped and he thought there was a fire, so he smashed out the train window and tried to get out. 24 hours in jail and a big fine.
In the US he'd have been in jail multiple times, if not beaten silly or killed by the police if he happened to run into one of those types.
I saw a girl fall down the steps in a Japanese movie theater. Everyone ignored it and I went to help but my friend stopped me. She said if she needs an ambulance we should help but otherwise we will just embaress her. I can understand the logic but it's pretty extreme.
Where are you in japan?
There you go. Japanese culture is so different.
I live in Shiga. You?
