The 44th Battle Training Zone also known as the Forest of Death was the stage for the second part of the Chunin Exams, proctored by Anko. Its primary function served as a testing ground for the survival and fighting skills of Genin trying to become a Chunin. It was a very dangerous place, filled with hordes of flora and fauna; often gigantic, poisonous — or even more likely, both — hence its name. A metallic fence surrounds its perimeter with 44 gates equally spaced around it; this perimeter is where the Shinobi entered. Inside is a river, the forest, and a tower located in the exact center; the forest's radius is about ten kilometers.
