Kirigakure

Kirigakure (霧隠れの里, Kirigakure; 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.

Kirigakure is composed
of several cylindrical buildings, with the Mizukage's palace being the
widest and the largest. Like its name, the village is surrounded by a
thick mist, with several mountains in the background, making it
difficult to find by foreigners.
