A vending machine on the street

Perhaps you may think that it is strange, but many vending machines also sell beer and other alcohols on the streets of Japan, though they are becoming less. People under twenty are prohibited from drinking alcohols but they can easily get them because there are such vending machines in Japan. Actually when I was high school student, I confess, I had bought beer by vending machines with some friends some times. Anyway, Japan seems to be peaceful.
