Amagisaki
There is an Amagisaki just NW of Osaka, on the way to Kobe. It is has a large JR rail junction, and recently, a new COSTCO has opened there, which is nice for me in Osaka. So it is a real city! Unfortunately, I'd have no idea how to go about searching for someone. Amagisaki city might have a home page, but I'm not sure how much might be in English. If you could some how send and email to some kind of Amagisaki tourism/visitor info site, I'm sure they'd find an english speaker who might be able to give you some answers. Hope that helps! Gambatte and good luck!
