Koorigakure

Koorigakure (氷の中に隠れる村, Koorigakure no Sato; literally meaning "Village Hidden Among the Ice") is the farthest northern point of the Shinobi world. Because it is so far far away from most Civilization, most Shinobi's Village's didn't know it existed for quite some time. It prefer's to handle it's affairs separately from the other Hidden Village's and hosts it's on Chunin Exam on it's own.
