As such, it is one of five villages with a Kage as its leader, known as the Hokage. On a mountain overlooking the villages from the north exists the Hokage Monument. The village resides in the Land of Fire. Although Konoha, much like the country in which it resides, has been peaceful for the past sixteen years, and has grown accustomed to that peace, it remains one of the most powerful villages in existence, and has great military power and influence.
~Kirigakure (霧隠れの里, Kirigakure no sato; Literally meaning "Village Hidden in the Mist"), called Kiri for short, is located in the Land of Water. The official head ninja of Kirigakure is the Mizukage. It is also the place from which the Seven Ninja Swordsmen of the Mist hail. Kakashi and Orochimaru have both stated that Kiri has a strong and ruthless military that cannot be easily defeated.
~Sunagakure (砂隠れの里, Sunagakure no Sato; Literally meaning "Village Hidden in the Sand") is the hidden village of the Land of Wind. As one of the five great ninja villages, Sunagakure has a Kage as its leader known as the Kazekage. The ninja from this village seem to specialize in Wind Release techniques and the Puppet Technique. Shinobi from Sunagakure believe that the accomplishment of a mission predominates the lives of the ninja trying to accomplish it.
~Otogakure-Hidden Sound is a motley collection of ninja from various clans and nationalities, all brought under Orochimaru's direction. Orochimaru traveled the world gathering jutsu and ninja in his goal to gain power. Rice Field clans like the Fuuma, volunteered for Orochimaru's army. Some clan members became soldiers in Orochimaru's army, while others were made prisoners to be used for his experiments. The village itself is a lower shinobi country. Before Orochimaru's full plans to destroy Konoha were revealed, the village was allied with Grass, Leaf, Rain, Sand and Waterfall.
