HIDDEN VILLAGE OF THE LEAF

Located in the land of Fire, Hidden Leaf Village is the largest and most powerful of all Hidden Shinobi Villages. Because it has a large population it has the biggest army just like China. 13 years ago, the Hidden Leaf Village was attacked by the Nine Tails Fox Demon (Kyubi).
eventually after killing and destroying many people It was defeated and sealed into the newborn child Uzumaki Naruto by the village's most powerful leader, the 4th Hokage. The 4th Hokage died soon after the battle ended, because of the Ninjutsu he used. Sacrificing his life and fulfilling his duty as the village's hokage. Since that time, power has returned to the 3rd Hokage who is later on killed by Orochimaru.

Village of the Hidden Mist

Not much is known about this village. Although it was commonly referred to by other villages as "Bloody Mist Village" for its rumored brutality. This is the village where Zabuza and Haku originated from before they abandoned the land. . The training customs of the village were revealed from Zabuza's childhood.
The final exam to becoming a ninja is much different from the exam for the students in Leaf Village. In order for a Ninja Academy student to graduate and become a Genin (lower level ninja) in the Hidden Mist Village, he or she had to fight, with one of the same friends they trained with, to the death. But all of this had to be changed 10 years ago when one of that year's students killed over 100 peers without hesitation. This child was Zabuza. Because of this the Village was forced to change the final exam for the graduating class. All of their Jutsu is based on water techniques.

Hidden Waterfall Village

The Hidden Waterfall Village, a very small village that we've only seen in Naruto's Jump Festa 2004 so far.
Because this village has no Kage, they have something called the Hero Water to help them protect their village. It's some sort of holy water which is extracted from the great tree (located in the Hidden Waterfall Village) every one hundred years. It is suposed to tenfold the user's chakra, and aid the 'heroes' in protecting their village in times of battle.
But this water is a double-edged sword, altough it increases one's chakra, it also eats away your liveforce at the same time. Only the young ones (most of the time younger means weaker, strength grows with experience) will be able to survive the effects of the water. For that reason, many of the village's shinobi have died not from battle, but from the water. And this holy water was sealed away. It's the village's leader's duty to protect the Hero Water at all cost. Because this village is small and has very few (strong) shinobi, it's build behind a Waterfall - hence "-The Hidden Waterfall Village-". Only its inhabitants know the village's entrance.

Hidden Sand Village

Located in the Wind Country, the Hidden Sand Village is one of the top 5 greatest Shinobi countries.Kazekage is the leader of this village, and is also the one who trains Gaara of the Desert.
The lord of the wind country is making an attempt to scale down the country's military presence and has cut back on the Sand Village's budget. Furthermore, he has commissioned tasks normally reserved for the county's own hidden village to the Hidden Leaf Village, raising speculation of an attempt to dissolve the Sand Village. To re-establish the Sand Village, Kazekage teams up with the Sound Village and plans to attack the Leaf Village, Konoha. (This attack is later foiled by the Shinobi of Konoha.) Kazekage is later on killed by Orochimaru.

Hidden Sound Village

The recently formed Hidden Sound Village, located in the Sound Country. Ruled and created by Orochimaru, a very powerful and talented Missing-Nin from the Hidden Leaf Village. Altough his true ambitions are unclear, Orochimaru's goal is to one day cause a civil war. He later on leads an attack with both the Hidden Sound and Hidden Sand Village on Konoha.
