The Gentle Fist (柔拳, Jūken) or Gentle Fist Art (柔拳法, Jūkenpō) is a form of hand-to-hand combat used by members of the Hyūga clan. It inflicts internal damage through attacking the body's Chakra Pathway System, subsequently injuring organs which are closely intertwined with the area of the network which has been struck. To do this, the user surgically injects a certain amount of their own chakra into the opponent's chakra pathway system, causing damage to surrounding organs due to their proximity to the chakra circulatory system. Even the slightest tap can cause severe internal damage, hence the name "gentle" fist.
Targeting the Tenketsu can enhance the havoc and control a Gentle Fist practitioner can impose upon an opponent's chakra network. These special nodes, 361 in total, are key gatekeeping interceptions in the chakra circulatory network, thus forcibly opening or sealing them in whatever manner the Gentle Fist user sees fit is a powerful tactical option to have. The user's chakra can either increase chakra flow in the opponent's body, or disrupt it completely, preventing them from using techniques as seen in Neji's fight with Hinata during the Chūnin Exams.
Neji Hyūga remarked that any chakra-based substance can be destroyed by this technique. As seen in his fight with Kidōmaru, it is done by leaking chakra from the chakra openings in one's hands and moulding it into a needle-like shape to slice through the chakra. However it is unknown if this technique can be done by any Gentle Fist user or just those who can see the tenketsu.
Because the chakra pathway system is invisible to the naked eye, the Byakugan is required for this style to be used effectively. Since the Byakugan is unique to the Hyūga clan, it has become their signature style of combat.
The ability to inflict severe internal trauma with minimal external force, combined with chakra network manipulation, makes the Gentle Fist the most reputable and fearsome taijutsu style known in all of Konohagakure.
