In the anime an manga series Naruto by Masashi Kishimoto a jutsu (術, jutsu? "technique" or "skill") is a general term referring to any technique a ninja might use that an ordinary human would likely be unable to naturally imitate. Jutsu often rely on the manipulation of chakra by various methods, the most common of which is hand seals, also known as ingei or mundra.
