I'm expecting to spend some significant time over in Japan in the next two years, and would like to add a routable map to my watch. Garmin doesn't offer one, and the ones that I downloaded from http://garmin.openstreetmap.nl are all in Japanese (working on learning, but progress is slow). Does anyone know where I might find a map in English (German or Dutch would work as well)? I don't mind paying for it if I have to.
