[NagasakiRenn]

so I'm doing the ever popular teach abroad in japan thing, and I just got my placement: a town called Ishiya in Nagasaki prefecture. Problem is, I am not entirely convinced that this town actually exists. after pretty exhaustive internet searches and pouring over maps of nagasaki prefecture, I haven't been able to even locate the town, let alone any information about it. My liason is unable to provide any other information besides the name, but she spelled it out, and I know that Ishiya is the exact name she was given. In fact, the only substantial information I can find on an Ishiya, Japan is a chocolate factory in Sapporo. There is a town in Nagasaki prefecture called Isahaya, and I suppose it's possible that somewhere along the line the name of the town got mixed up, but my liason was pretty confident that it was called Ishiya. Has anyone heard of this town, or have any advice for someone (presumably) moving to Nagasaki prefecture in the near future?
