Kirigakure

Kirigakure no sato (霧隠れの里), "The Village Hidden in the Mist" or Hidden Mist Village, plays a small role as the home village of Zabuza Momochi in the Mission to the Land of Waves arc. Its village layout is relatively unknown, only seen briefly in flashbacks by Kimimaro. The only major events that are known to have occurred at this village is the annihilation of a graduation class of genin by Zabuza himself, and a village attack by Kimimaro's clan about 15 years later.

The village, according to Kakashi, was known for a barbaric graduation ritual. Students wishing to move on into the ranks of the ninja there would be pitted against each other in one-on-one duels to the death, thus earning the village the nickname, "Village of the Bloody Mist". This atmosphere led to the emergence of Zabuza Momochi, and after the incident mentioned above, in which the entire graduating class was killed (and, at the time, Zabuza had not even reached the age of graduation), the graduation event was changed. Zabuza was consequently given the name, "The Demon of Kirigakure".The mist village develops strong and ruthless ninja as kakashi has stated befoe and Orichimaro once said that the mist village is a powerful military that would not be defeated easily.

Mizukage is a kage of Kirigakure. Seven Mist Swordsmen hail from Kirigakure as well - only three names were revealed so far: Raiga Kurosuki, Zabuza Momochi and Kisame Hoshigaki. Suigetsu is also originally from Kirigakure.
