Amegakure

, also known as Hidden Rain Village, is a small yet highly industrialized hidden village located in an unnamed country. It seems to be a rather loosely knit village, befitting the destabilized country, as a fair number of its ninja seem to either be missing-nin or end up as missing-nin, as the infamous Akatsuki leader Pain and his partner Konan originate from this village. Its symbol is composed of four parallel vertical lines, resembling rain.

History
Lacking a Kage leader, Amegakure was once led by Hanzo the Great Salamander, though he was killed during the Land of Rain's civil war by the Akatsuki leader, Pain. Pain now uses the village as his base of operations for Akatsuki and reigns as an enigmatic godlike figure over the townspeople. Those loyal to the former Amegakure attack the village on occasion in an attempt to assassinate Pain, though their efforts are never successful.

Due to being involved in a great deal of strife, the village prefers to keep a low profile. Its country was used as a battlefield during much of the Third Great Shinobi War, and so war refugees make up a large portion of the population. When the Civil War began, the country only had to endure more chaos and destruction. Embarrassed by this conflict, the village adopted a sort of isolationist policy. Anyone who entered the village that was not originally from the village would be required to tell the village staff their names, why they're there, and how long they planned to stay. This policy would stand firm even when Amegakure would host the Chunin Exams.

Chunin Exams
At least three of their Genin teams advanced to the second stage of the Chunin Exams held in Konoha during the Chunin Exam arc. The first team is killed by Gaara (Team Shigure), while the second team (Team Oboro) is defeated by Team 7 near the stage's end. This second team appears once more during the Tea Country filler arc, along with a former Konoha Chunin, Aoi Rokusho. In the anime, a third Amegakure team is quickly defeated by Team 8 the moment the second stage of the exams began.

Trivia

 * The country Amegakure resides in is currently unknown, but because of the very rainy climate and its hidden village called the Hidden Rain, the country has been called the by fans.
