Yamato (ヤマト?) is introduced during Part II of the series as a temporary replacement for Kakashi Hatake as the leader of Team 7.[12] After Kakashi's return, he stays on the team in an additional leadership position. Though "Yamato" is a codename assigned to him for the purposes of joining Team 7, he prefers it over his real name, Tenzo (テンゾウ, Tenzō?). During his infancy, Yamato was abducted by Orochimaru and experimented upon in an attempt to replicate the First Hokage's unique abilities. Orochimaru was forced to flee Konohagakure before he could complete his testing, and thus never knew that Yamato had successfully obtained the First's Mokuton techniques.When using Mokuton techniques, Yamato can form anything out of wood at will, and is not above using this ability for making creature comforts like two-story houses to "camp out" in. Mokuton also allows Yamato to suppress a tailed beast's influence over its host. This is the primary reason he is assigned to Team 7, as he can stop Naruto Uzumaki if the nine-tailed demon fox within him gets out of control. In the Naruto: Shippūden anime, Yamato's seiyū is Rikiya Koyama.
