What other animes use ninjutsu as naruto??????????

AKA %26quot;HAND SIGNS%26quot;|||None that I know of. I%26#039;m pretty sure only Kishimoto thought of that, BUT you should look into all ninja anime/manga you can find and see if they use hand signs. There%26#039;s only one hand sign I see ninjas use, but it doesn%26#039;t do anything. It%26#039;s probably just for concentration.
