Japanese city naming 

Hi - I've revised my post at Wikipedia talk:Manual of Style (Japan-related articles) since, based on your response, I see I was not being clear at all.  The question I meant to be asking is whether common name alone (e.g. Nagano) should ever be used as an article name, not "city" as a suffix.   I'm trying to help get to a consensus by dividing the issue into two steps.  Step 1 - do we always need a disambiguated name for the city articles (disambiguated by any technique)?  If we can gain a consensus that the answer is yes, then step 2 is "OK, what should be the disambiguation technique"?   Rick Block (talk)
