Yugakure

This is the village that the Akatsuki member Hidan originated from. As seen on Hidan's forehead protector, its symbol is three curved diagonal lines, similar to the Amegakure symbol and resembling rising steam. Once a ninja village, Yugakure decided that it didn't feel like staying a hidden village and transitioned out into a peaceful and prosperous village instead. However, Hidan, growing up, already showed a tendency toward violent Jashinist ways, decided that he didn't like this and slaughtered his neighbors before leaving the village.
