Kappo (活法, kappō, "resuscitation techniques") are healing techniques that often involve stimulation of specific acupuncture points. Kappo is commonly used in martial arts such as Danzan Ryu and Judo. Kappo contains two kanji: katsu (活 “resuscitation, life”) and ho (法 “method”). A tradition in some Judo schools involves teaching kappo to all new shodan (black belts). This instruction is followed by a session where each of the shodan choke someone, are choked themselves, and resuscitate someone using kappo.
