Yugakure

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.

Yugakure makes an appearance in the series in Shippūden episode 92. When Kabuto Yakushi and Yūkimaru are on a journey they stop here to rest. Yūkimaru meets Naruto Uzumaki in a hot spring and talks with him about how hearts can communicate. There wasn't much seen from the village in the episode, but it seemed small and had no protection walls, like other ninja villages had. This was probably because the village no longer existed as hidden ninja village.

Trivia

 * This is the only known village that has been converted from a shinobi village to a tourist place instead.
 * Yugakure has one Akatsuki representative: Hidan.
