Nihon Nukite is a technique in Kyokushin karate. It translates to 'Two-Finger Spear Hand.' This technique involves thrusting with two fingers extended in a spear-like motion. The term 'Nihon' refers to two, and 'Nukite' indicates a spear hand strike. It is commonly used to target vulnerable points on the opponent's body such as the throat, eyes, or solar plexus with precision and speed.
