Yagura (やぐら) was a shinobi from Kirigakure and the host of the Three-Tailed Giant Turtle. When the Three-Tails was captured by Akatsuki, it had no host and roamed out in the wild. Why the beast was removed from this jinchūriki is unknown.

Because Yūkimaru has some control over the Three-Tails, and because he has some resemblance to this jinchūriki, it is speculated that they have some connection to each other, however Yūkimaru is a anime-only character that does not appear in the manga.
