Sarutobi Hiruzen was known as the Professor, a ninja with extraordinary skill and knowledge of jutsu. He was chosen as Hokage over another talented ninja named Danzou. Sandaime Hokage became Hokage at a very young age.

Like Shodai Hokage, Tobirama helped establish the principle that the Hokage will die for those people precious to them. Senju Tobirama also helped in the founding of Leaf, he was the younger brother of Hashirama. The Hokage would love his village and do all in his power to protect it, even giving his life in the line of duty to ensure its survival. The Hokage serves as the foundation which Leaf village sits. One of the founders of Leaf, Senju Hashirama helped establish the ideal of all the Hokage who followed. So you may see Kage who have yet to appear in your viewing of the anime. Warning! The listing of these Kage go through the most recent chapters of the manga. The Kage are the leaders of their respective hidden villages and the ninja which inhabit their country. These five individuals are called the 'Five Kage,' they are Watershadow (Mizukage), Fireshadow (Hokage), Windshadow (Kazekage), Earthshadow (Tsuchikage) and Lightningshadow (Raikage). Out of all the shinobi countries of the world of Naruto, the five most powerful are allowed to call their leaders by the Kage (Shadow) title.
