Kumogakure

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. The ninja from this village seem to specialize in Lightning Release techniques. A notable minority also seem to favor the use of Japanese-style swords (or katanas) as standard weapons, instead of the typical kunai that most shinobi wield; and, as a result, many Kumogakure ninjas seem to excel at swordsmanship. The village is located in a range of tall mountains, and is literally hidden in the clouds. The Raikage lives in a large building built into the tallest mountain.

Kumogakure, like Iwagakure and Kirigakure, had two tailed beasts in its possession: the Two-Tailed Monster Cat in Yugito Nii, and the Eight-Tailed Giant Ox in Killer Bee. What makes this village unique is the fact that the villagers were outraged when both Yugito and Killer Bee were captured by Akatsuki, as most villages had shunned their Jinchūriki. Yugito and Killer Bee had a great deal of control over their tailed beasts, such that both were able to fully transform into their beasts. Due to the immense powers of releasing their beasts fully, despite retaining control of themselves, the Fourth Raikage forbade at least Killer Bee from doing so.

Kage Summit
Shortly after the Fifth Kazekage's abduction, Yugito was captured by Kakuzu and Hidan of Akatsuki, and she died after her tailed beast was extracted, a loss that the village was furious about. After Killer Bee (the Raikage's brother) was captured, the village started dedicating its time to deal with Akatsuki.

Due to Sasuke Uchiha being the one who had kidnapped Killer Bee, Kumogakure felt that Konohagakure was responsible for sparing Sasuke's life even after his defection. As such, animosity between the two villages rose, similar to when Hiashi Hyūga killed their Head Ninja.

As the Fourth Raikage has been put in charge of the Shinobi Alliance and they managed to retrieve Killer Bee, who had escaped earlier, Kumo's stance in the world has grown considerably.

Shinobi
The organization of Kumogakure's shinobi is slightly different from other villages. Besides the normal ranks of Kage > Jōnin > Chūnin > Genin, Kumogakure has an extra rank, that of. It seems that this rank is placed between Kage and Jōnin. It is unknown if this position is still applied.

During the time of the First Great Shinobi World War Kumogakure had a group of elite shinobi known as the Kinkaku Force who were known for their excellent tracking skills.
