In Japan, there is a wonderful type of drinking establishment called a standing bar.
When thinking of Japan, etiquette being important and there being lots of rules comes to mind, but at standing bars, born from the need of hard-working salarymen pressed for time to drink quickly without worrying about the finer details of etiquette, in a sense you can see another side of Japanese culture.
I believe standing bars have a mysterious kind of power. Its easy to let loose and open up to the customers around you, because you are already so physically close. And best of all, the cost is great. No matter how you look at it, standing bars are the best.
Besides the fact that standing bars are the best, I should mention that for many people it is easy to enter, but hard to leave. It isn’t unusual to see an office worker who has been standing for three hours drinking. Surely that man intended to just have a quick drink and go home. If you are planning to be somewhere for three hours, usually you’d want to sit down.
But someone like that is a real professional in matters like that. They don’t take any notice of fatigue in their legs when they are deep in their cups. This is something that shouldn’t be imitated, and in any case imitating it is more easily said than done.
I would recommend carefully considering the sightseeing you’d like to do the next day and leaving the bar without a fuss after 45 minute or so, no matter how much fun you are having.
