Don't smoke on the street
In most areas of Tokyo, you are not allowed to smoke on the street.
If you ignore this kind of signs on the street and still smoke, you might get fined 1,000 to 20,000 yen, depending on the administering ward.
On the other hand, there is no punishment for drinking alcohol on the street.
You don't have to hide your bottles in a bag here. Different countries have different rules.
