Five Kage Summit arc
He was first seen preparing for travelling to the meeting of the five Kage, and received a bid from his village to return safely and, at the same time, display to the other Kage how powerful the one from Iwagakure stands out, accompanied by an incredibly large young fellow named Akatsuchi as well as an insulting young ninja named Kurotsuchi, who even suggested that he should retire soon.

Albeit complaining about his hip, he still wanted to carry his own bag, and ranted about being the Tsuchikage, only to hurt his back when he put on his backpack. Akatsuchi had to carry him all the way to the summit.

Later, while resting, Ōnoki tells Kurotsuchi and Akatsuchi about the Land of Iron, where the meeting is to be held. Upon arrival Ōnoki presents his Kage hat that denotes his position as Tsuchikage.
