I know that all of the villages now hold their Chunin exams together and have since the Third Ninja World War. The only two in-canon Chunin exam that have been seen, however, were held in Konoha. Are all Chunin exams held in Konoha? If not, how is it decided where they are held?
EDITED: According to www.naruto2.com, no. It can be held in different ninja villages as well. And because of convenience purposes, the village with the most participating ninjas will host the Chuunin Exams.
