Here’s a map that my girlfriend and I created inspired by the work of Camyron (OG post : Mausugado: Mouse Guard in Feudal Japan)
We tried to be as faithful as possible to the source material using the geography of Japan as the base. I hope you can use it and have fun with it as much as we intend to do - https://imgur.com/a/fNphWuC
Don’t forget to zoom in to check the details, since the zoom from imgur is quite poor.
Cheers!
