Days: Kumamoto Bars
In my various drunken sprawls around the downtown kumamoto area, I'd have to say bar days is the coolest bar found yet. Kind of a rock grungy feel to it, but if you're into music this is the place to be cos it has around 1000 cd's lining the walls.
Reading the other comments, sanctuary is no doubt a cheap place to get a drink, but it's also a little on the grimy side so don't expect too much if you go there. However, it's open late and isn't that hard to find, so it may be worth a shot if there's nothing else going on.
