Characteristics of the Art:

Aiki-Jujutsu Gyakute-Do is a unique system of self-protection that maintains one foot in the past, through its teaching of classical Jujutsu techniques, and the other foot in the modern era, through advanced study of subtle aiki methods, or Aiki-jutsu. "Aiki" in the art of Gyakute-Do is the use of subtle physical and psychological methods to control an aggressor with a focus on “mental intent”.

The Techniques of Gyakute-Do:
The techniques of Gyakute-Do are arranged in the following categories.

  • Nuki Waza (Release Techniques):  Nuki Waza are techniques of escaping from various grabs and restraints that may be used by an attacker. These are the most fundamental self-defense techniques.

  • Renko Waza (Arresting Techniques):  These techniques involve applying various joint locks and controls against an aggressor that end in a restraint, where the opponent may still be escorted or forced to come-along with the defender. As the name suggests, these are techniques often employed by law enforcement and security professionals.

  • Nage Waza (Throws):  Throwing techniques in Gyakute-Do take the form of projections, trips, and hip or shoulder type throws where the practitioner of Gyakute-Do off-balances an opponent and throws then to the ground.

  • Fudo Waza (Immobilizations):  Fudo Waza are techniques whereby the defender pins or restrains the attacker in an immobile position (unlike the previous Renko Waza), typically on their stomach or back.  These techniques incorporate various joint locks and controls that induce pain compliance from an attacker.

  • Aikijutsu Waza (Harmonizing Techniques):  Aikijutsu techniques consist of employing subtle physical and psychological methods to control an aggressor.  These are the most advanced techniques in Gyakute-Do and are deeply founded in the use of “mental intent” and special body “structure”. The attacker is often unaware that they are being controlled until it is too late and these techniques make minimal use of power and energy from the defender.

  • Daken-Ho (Striking Methods):  Daken-Ho is a system of blocking, striking, and kicking taught within Gyakute-Do. These techniques were adopted from Kensei-ryu Karate, but make use of techniques that would not cause significant injury to the attacker. Daken-Ho techniques are taught as pre-arranged forms (Kata) in Gyakute-Do, where the attacker and defender exchange a number of strikes, blocks, defections, and kicks.


The techniques of Aiki-Jujutsu Gyakute-Do are neither overly sophisticated, nor artificially beautiful, as is often seen in similar styles. Its techniques retain the classical flavor of its root arts, and carry-on the essence of feudal-era samurai bujutsu (martial arts). In this way, the art of Aiki-Jujutsu Gyakute-Do is a complete system of self-defense, appropriate for all people, young or old, large or small.

What is Gyakute-Do?

Gyakute-Do is a style of traditional Japanese self-protection, descended from the classical (Koryu) Asayama Ichiden-ryu school of feudal-era Jujutsu, and the modern Hakko-ryu school, a branch of the famous Daito-ryu school of Aiki-Jujutsu.

“Gyakute-Do” translates as the “Way of the Reversed Hand”. It is a play on words that describes the art’s focus on joint locking techniques applied to the wrist and arm (gyakute), which are weak points in the human body, and a very effective means of controlling others without causing serious damage, or requiring significant strength to execute.

Aikijujutsu Gyakute-Do:  Japanese Self-Protection Arts

The term “gyakute” comes from techniques found in one of Gyakute-Do’s parent arts, Asayama Ichiden-ryu. This is the origin behind the name "Gyakute-Do".  The art was originally named Goshin Bugei Gyakute-Do (Self-Defense Martial Way of the Reversed Hand) by the founder, Tadashi Chushudo Tanaka, Soushi (Headmaster), in the 1970s. Tanaka Soushi studied Kenso-ryu Jujutsu (a branch of Asayama Ichiden-ryu Okura-den), Goshindo (a branch of Hakko-ryu), Hakko-ryu, Jujutsu and Kensei-ryu Karate. The art is currently overseen by the 2nd Headmaster, Makoto Shiseido Kurabe, Nidai Soushi, in Chiba, Japan. Kurabe Soushi expanded the Aikijutsu portion of the curriculum and formally renamed the school Aiki-Jujutsu Gyakute-Do.
