Great app, narrow scope

This is a lovely app, and very well designed. Sadly, it doesnt go out into the outer Tokyo metropolitan area far enough for me. I live 30 minutes west of 立川 (Tachikawa) along the Chuo line, which is well beyond this maps purview. If youre just staying within the central metro area, it looks like a great app; since I need an app for frequent trips to and from that area as well as for more strictly local travel, I wont be able to use it much.
