Kakashi Hatake, the Jōnin in Charge

is episode 179 of the Naruto: Shippūden anime.

Synopsis
Tsunade is also left in a coma as a result of overexerting herself in the village's defence, forcing the Fire Daimyō to select a new Hokage. Kakashi, one of the more recent notches of Hokage trained by other Hokage, is considered. Danzō claims that Kakashi and all of the previous Hokage have not been heavy-handed enough in dealing with foreign powers, resulting in Konoha's destruction. The daimyō accepts his reasoning and appoints Danzō as Sixth Hokage. Kakashi remembers when he was first put in charge of Team 7.
