Passai (披塞) is the Japanese name of a group of kata practice in different styles of martial arts, including karate and various Korean martial arts (Taekwondo, Tang Soo Do, Soo Bahk Do). There are several variations of these kata, including Passai sho (minor) and Passai dai (major) . In karate, the kata are known as Passai in Okinawan styles and Bassai in Japanese styles. In Korean, the kata has several names: Bassahee, Bal Se, Pal Che, Palsek, Bal Sae, Ba Sa Hee, and Bal Sak. The kata focus on the idea of changing disadvantage into advantage by strong and courageous response, switching blocks and differing degrees of power. The feeling of kata should be precise, with fast execution of technique and attention given to appropriate balance between speed and power. The Passai kata are usually classed as intermediate kata.
