Kinjutsu

Kinjutsu are techniques that are banned by a certain community (i.e. Konoha), such as the Multiple Shadow Clone Technique. Naruto Uzumaki had to learn the technique by stealing the First Hokage's Scroll of Sealing. Kinjutsu are jutsu that have been banned because of their high chakra usage, damage to the user (from total exhaustion to the possibility of killing them), or because their usefulness has ended when war has ended. Kinjutsu are also so named due to violating certain laws of nature such as reviving the dead.
