Yamagakure was founded by a man known simply as Inshi who believed in Iwagakure's reclusive ways and so he built Yamagakure within a massive canyon that branches out into smaller canyons so for one who is not from Yamagakure they would have a bit of a hard time getting there. The main canyon that the village lies within is surrounded by a wall of mountains that work as a natural defense for the village.
