The Forest of Death (死の森), also known as the 44th battle training zone, was the stage for the second part of the Konoha Chunin exams. Its primary function served as a testing grounds for the survival and fighting skills of Genin trying to become a Chunin. It is a very dangerous place, filled with hordes of flora and fauna; often gigantic, poisonous – or even more likely, both – hence its name.
There are four entrances into the forest. A metallic fence surrounds its perimeter with 44 gates equally spaced around it; this perimeter is where the ninja enter to initiate the test. Inside is a river, the forest, and a tower located in the center; the forest's radius is about ten kilometers.
