Kumogakure no Sato

Hidden Cloud is one of the more powerful ninja villages in the world, allowing its leader to be called a "Kage." As such it is one of the Five Great Shinobi Countries. Approximately 9 years before the start of the series, Hidden Cloud and Leaf were locked in war. The two countries decided to sign a peace treaty to end the conflict. Unfortunately Hidden Cloud used the treaty signing as a means to gain access to Leaf and then kidnap Hyuuga Hinata and get the Byakugan. Cloud is also one of the shinobi countries to utilize Jinchuuriki. Cloud ninja Nii Yugito was the host of the two-tailed cat demon. The Raikage's brother Killer Bee was the host of the eight-tailed ox-cephalopod demon.

With the new Raikage, Kumogakure has been preparing for the war with all sorts of surprises for the other side.
