Yagura Karatachi

was the jinchūriki of the Three-Tailed Giant Turtle and the of Kirigakure. When the Three-Tails was captured by Akatsuki, it had no host and roamed out in the wild. The reason why the Three-Tails was removed from Yagura is unknown.

History
During his time as Mizukage, until the massacre of Academy Students by a young Zabuza Momochi, the village was known as the, due mostly because of the barbaric ritual where Academy students kill one another for graduation. It is likely that Yagura was the Mizukage who Zabuza tried to assassinate.

Despite the terror of his reign, he appears to be kind. Apparently the people of Kirigakure fear that Yagura was being manipulated, a fear which was confirmed by Ao, who saw through an unnamed genjutsu with his Byakugan. This could possibly be the reason for Yagura's harsh policies, as the one who was misleading himm might have forced him to take Kiri down such a dark and bloodstained path.

Trivia

 * The stitched scar down on Yagura's left cheek might be connected to the Three-Tails' single open eye.
 * Because Yūkimaru has some control over the Three-Tails, and because he has some resemblance to Yagura, it is speculated that they have some connection to each other; however, Yūkimaru is an anime-only character that does not appear in the manga.
 * Yagura is one of only four people( and one of only two Jinchūriki) said to be able to truly control a tailed beast, the others being Hashirama Senju, Madara Uchiha, and Killer Bee.
