Well, not really...

This is NOT a map of the Tokyo Metro system, but a map of the JR train lines in the greater Tokyo area. As far as that goes, its a very complete map showing all the JR train lines and stations in English, but it does NOT show any of the Tokyo Metro subway lines.

Its a bit oversensitive to movement, the image tilts wildly when I try to zoom or reduce size, resulting in some (temporary) image distortion and making my brain hurt.
