In Naruto's case, they weren't formally labeled as arcs (unlike One Piece), but you would have titles given to certain segments. I'm not sure if you're familiar with Naruto, but one arc was originally called the "Hidan and Kakuzu arc" by Narutopedia, only for it to be changed to "Akatsuki Suppression Mission", which is what the databook called it. I've seen similar things for World Trigger here.
