It was something I have heard about Japan before coming, but I did not expected to be as pronounced as it is. There was the “rumor” that Japanese men after work would go straight to the bar before getting home. And in fact, it is not completely wrong.
Drinking in Japan is popular. The parks at night are full of young and older people that hang in group or couple drinking alcohol. Bars are full any night of the week and weekends. It is socially accepted to take drinks any time a day as well.
I do not believe it is a bad thing, knowing that Japanese are pretty quiet and alcohol helps them get close to others, but it is crazy to see on a Monday night a person passed out on the street. Or at 11p.m on every nigths, see people trough up or taking the train home completely drunk.
Japan’s drinking habits are very much far from the French one, where being drunk in the street is a crime and not accepted.
