This search turned up very few hits. It seems people all over Japan utter the standard phrase “Hajimemashite” (初めまして) when meeting someone for the first time. That’s to be expected, I suppose. Why, even loquacious Americans can become rather stiff and uncomfortable around strangers. Dōzo yoroshiku onegaishimasu.
