Like most bars and pubs, gay bars range in size from the small, five-seat bars of Tokyo to large, multi-story clubs with several distinct areas and more than one dance floor. A large venue may be referred to as a nightclub, club, or bar, while smaller venues are typically called bars and sometimes pubs. The only defining characteristic of a gay bar is the nature of its clientele. While many gay bars target the gay and/or lesbian communities, some (usually older and firmly established) gay bars have become gay, as it were, through custom, over a long period of time.
