Yamato is a member of Konoha's ANBU, and a younger peer of Kakashi Hatake. He is also the temporary leader of Team Kakashi, and one of the main protagonists of the series. "Yamato" is actually a codename given to him by Tsunade for the purposes of joining Team Kakashi. While Kakashi was still in the ANBU, his codename was Tenzou. Kakashi sometimes still calls him Tenzou, although Yamato prefers his new codename.

Like other ANBU members, Yamato projects a calm, stoic demeanor in stressful situations. Despite this, he can also be quite laid back when not on duty, and is not above using his Wood Release techniques for creating comforts, such as making a house to "camp out" in.

Yamato is somewhat reluctant to pay for things unless he has to, as he initially protested at having to pay for lunch at Ichiraku Ramen Bar, stating that Kakashi should pay, being the senior ninja, but was flattered into paying when Kakashi said he considered Yamato an equal.
