Locating a Station

Hello,

So I was wondering if there's a way to locate the closest station you'd be able to utilize this pass at? I really don't want to have to be worrying about getting to a station and then finding out they don't accept the pass. I'm going to be starting in Osaka and then making my way through both cities like Kyoto and Tokyo, but I also will be going to smaller cities and want to make sure I have all the information I need before purchasing this pass.
