Just from reading here, it seems like publicity is the greatest problem for a lot of places. Make business cards and flyers; make sure everyone everywhere knows you exist. Let people drop in and see, try to get a core group together so that there's something for them to watch. Even if you tell someone who has no interest in kendo, THEY might mention it to someone else who's interested in swords, anime, or martial arts in general.
