Land of Sound

The Land of Sound, along with Otogakure, is a relatively new country in the political scene, though the country itself existed long before Orochimaru took it over and renamed it. It conspired with the Land of Wind to launch a surprise attack and hopefully destroy the Land of Fire. Instead of using elemental jutsu, Sound ninja use sonic-based jutsu, often augmented by various devices.

In the anime, the country in which Orochimaru established his village is named the. Orochimaru seems to have renamed it after his takeover.

Otogakure
was founded by Orochimaru as a part of the Land of Sound, and is run by him. Not much is known about it: what is certain is that it actually consists of a series of lairs, located both within the Sound country and away from it, which Orochimaru switches between every week. Other than that, and the fact that its ninja specialize in techniques involving manipulation of sound waves, as well as using a cursed seal to increase their power, little else is known about it. Although he is the leading ninja of Otogakure, Orochimaru isn't a Kage, despite his equivalent power level. The reason for this is because the five Kages of the five great Hidden Villages don't acknowledge Otogakure, and certainly would not acknowledge a criminal like Orochimaru.

With Orochimaru's defeat at the hands of Sasuke Uchiha, the various bases formerly under Orochimaru's control have begun to rebel and their inhabitants are trying to escape to freedom.
