Jodan Koken Uke is a technique in Kyokushin karate. It translates to 'Upper-Level Wrist Block.' This technique involves using the wrist to block incoming strikes aimed at the upper body or head. The term 'Jodan' refers to the upper level, 'Koken' indicates the wrist, and 'Uke' refers to the blocking motion. It is commonly used to intercept punches, kicks, or strikes directed towards the face or neck area, deflecting them away from the body and creating openings for counterattacks.
