TGIF!! I wanna get some beer after work too!
In Japan, you can find lots of bars and drinking places like the "izakaya" where you can get alcoholic drinks and food. Not just for people who work, actually you can see young people and even women drinking in restaurants too!
By the way, do you know that the legal drinking age in Japan is 20 years old? What is the minimum legal drinking age in your country?
