Kirigakure no Sato

Kirigakure (Kirigakure no Sato, literally Village Hidden in Mist) or Kiri for short is one of the five great hidden villages and is located in the Land of Water. Its leader is the Mizukage. Little is known about Kirigakure, except that its ninja specialize in water-based jutsu. However, it would also seem that many of its ninja wield swords, based on flashbacks in the anime. In the past, the graduation exam for becoming Genin was rather inhumane: students who had been friends, trained together, and ate from the same table, were pitted against one another in fights to the death. Kakashi mentioned that for this exam, the village earned the nickname the Village Hidden in the Bloody Mist. This gruesome method was cut short, however, when Zabuza Momochi, a boy who had failed to pass the preliminary exam to even attend the ninja academy, went mad and killed all of the students in that year's graduating class.
