Teisho Uchi, in the context of Shotokan Karate, refers to a strike executed with the palm heel (Teisho) of the hand. The Teisho is the area of the hand located at the base of the palm, typically used in karate techniques where a blunt force is required rather than a cutting or piercing action. Teisho Uchi involves striking with the palm heel in a forceful, pushing motion, often targeting soft and vulnerable areas of the opponent's body such as the nose, chin, or solar plexus. This technique is valued for its effectiveness in close-quarters combat and self-defense scenarios, leveraging the strength and stability of the palm heel to deliver impactful strikes. Teisho Uchi is an essential part of karate training, focusing on developing both power and precision in hand strikes.
