Earth Country - Hidden Rock Village

Hidden Rock 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 13 years before the start of the series, the village was at war with Leaf. Their invasion path took them through the Grass Country. The efforts of the man who became Fourth Hokage and his team consisting of Hatake Kakashi, Uchiha Obito and Rin helped turned back their assault.

Lightning Country - Hidden Cloud Village

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.

Rain Country - Hidden Rain Village

The Land of Rain is home to Amegakure or Hidden Rain Village, and is filled with a great number of small buildings in a heavily wooded area, suggesting that it might perhaps be located in a rainforest. Its borders are highly defended, and those wishing to pass through the country must first give their name, purpose, and amount of time they intend on staying in the country before being allowed admission. Even if one is permitted to enter the country, they will be under constant surveillance by the government for the duration of their stay.

Grass Country - Hidden Grass Village

A small country surrounded by the Lands of Fire, Rain, Bird, Earth and Waterfall. This land has an abundance of bamboo forests, grasslands, rivers and mountains. Little more is known about the country except that it’s speculated that Grass ninja specialize in nature or plant jutsus. The most notable shinobi from Grass country is Zetsu. The country was invaded by Rock ninjas during the Great Ninja War. Sasori's meeting point with his spy, Kabuto, was set at the Tenchi Bridge in the Land of Grass. The hidden village is called Kusagakure, Village Hidden Among Grass, and is located in the Land of Grass.

Waterfall Country - Hidden Waterfall Village

The majority of information on Hidden Waterfall was stated in OVA #2. Unfortunately the movie sits outside of manga continuity so village information may be proved one day inaccurate. The village itself is a lower shinobi country, being allied with Grass, Leaf, Rain and Sand. As such it participates in the Chuunin Exam with these countries. In the Chuunin Exam Naruto participated in, no Waterfall team made it beyond the second exam test. The village itself appeared to not have many active ninja when former Jounin Suien attacked the village, instead relying upon Naruto and Shibuki to defeat the ninja. For the sake of their reputation, we will assume most of the ninja were away on missions.

Iron Country - Tetsu no Kuni

The Iron Country is a small neutral land formed by three mountains called the "Three Wolves." It maintains a unique culture and strong military which uses samurai for protection. Ninja villages respect their neutrality and do not challenge their force. Their neutrality made them a good location for the Kage Summit called by the Raikage.
