A Japanese!pub would probably be a
Nomiya - they are almost the equivalent of a British pub; somewhere you would go for a beer after work, or watch baseball on weekends. Mostly people sit down at counters or tables, though, as opposed to standing around. Nomiyas serve snacks such as Yakitori together with beer (maybe they used to serve Japanese Sake? I'm not sure, I'm too young to know, hee!), and the customers are mostly men coming home from work...
I've Googled Nomiya (in Japanese), as pics might give you a better idea!
