Kumogakure (雲隠れの里, Kumogakure no Sato; Literally meaning "Village Hidden in the Clouds") is the Hidden Village of the Land of Lightning. As one of the five Great Ninja Villages, Kumogakure has a Kage as its leader known as the Raikage. Use of lightning release techniques and swords seem to be common of ninja from this village. The village is located in a range of tall mountains, and is literally hidden in the clouds. The Raikage lives in a large blue structure built into the tallest mountain.
In the Land of Lightning, there is a gigantic and ancient turtle that Kumogakure has cared for since its founding. It serves as a training ground for the Kumo ninja, and is described as a moving fortress. Its size is so great that it can host other large animals as well as other natural and man-made structures. It is considered to be the equivalent of Konoha's Forest of Death.
The forest literally looks like a forest of dead, pure white trees - all year around, and remaining the same yet somehow managing to exist. The forest is covered in Clouds, making it hard to see sometimes.
