Karate, meaning ‘empty hand’ in Japanese, is a martial art and combat sport that’s become one of the most popular styles practiced worldwide. Karate consists of typical striking techniques such as kicking and punching, but is unique in its inclusion of ‘open hand’ fighting techniques such as knife-hands and spear-hands. As a martial art that focuses on deflecting attacks, it’s a good choice for people interested in learning a self-defense style.
