Amegakure

Amegakure no Sato (雨隠れの里, literally "Village Hidden in Rain"), also known as Hidden Rain Village and commonly known as Amegakure, is a small hidden village in the Land of Rain that appears highly industrialized. 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.

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, Pein. Pein 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 Pein, though their efforts are never successful.

Chunin Exams
At least three of their Genin teams advanced to the second stage of the Chunin Exam 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 Jonin, Aoi Rokusho. In the anime, a third Amegakure team is quickly defeated by Team 8 the moment the stage begins.
