Forty-Fourth Training Ground

The 44th Battle Training Zone, also known as, was the stage for the second part of the Konoha Chunin exams, proctored by Anko Mitarashi. 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.

Chunin Exam Arc
The tower was the destination of the ninja after they had collected two scrolls. Each team started with only one scroll, either the Scrolls of Heaven or Earth; therefore, to pass the exam, a team had to find a team with the opposite scroll and steal it by any means necessary. They then finished the journey to the tower.

Inside the tower is the large arena in which the third test preliminaries were held, if too many teams managed to survive to that point. Relatively few teams complete this part of the test.
