Amegakure's location between three of the Five Great Shinobi Countries has caused it to serve as a battleground during the various ninja wars, making most of its population war refugees. Amegakure has adopted a heavy isolationist policy because of this, leading the village's defenses to be abnormally impenetrable. To be admitted to the village, visitors, even those coming for Chūnin Exams held in Amegakure, must go through a number of security checks and are under constant surveillance during their stay.
