Daitō-ryū Aiki-jūjutsu
Hakko Ryu is a style of self-defence that targets the pressure points and nerves sensitive to pain. The sensitive pressure points or "tsubo" lie along the meridians "keiraku" through which the "qi" flows, and striking these points can create momentary intense pain. This allows the defender to control, subdue or warn off an attacker. The technique relies on efficiency rather than power and strength, and its training emphasizes stretching, flexibility, and the suppleness of the body. It employs joint techniques, but has few strikes and kicks, and "tai sabaki" are seen in many of its techniques. Its throws often use joint-locks and are similar to those of Daitō-ryū Aiki-jūjutsu and Aikido rather than Jujutsu or Judo.
