Nintai

Definition of the Nintai Ryu Aiki Ju-Jitsu

Aiki Ju-Jitsu of the Nintai Ryu (or ‘school’) is a complete martial art, a discipline of body and spirit. Efficient and realistic combat and self-defense form the foundation of the style. Dedicated practitioners of this martial art are able to physically control or neutralize one or more adversaries.

Nintai Ryu Aiki Ju-Jitsu has its origins mainly - but not only - from traditional Japanese martial arts. It is influenced partly by the style of Grand Master Minoru Mochizuki but is neither a replica nor a continuity of that style. It is an innovative version and methodology that applies to the modern world. Nintai Ryu is ideal for self-defense, defense of a third party, and for physical intervention.


Training is serious and intense, but is practiced diligently and safely, and is tremendously beneficial to your health. Practice permits learning martial techniques and strategies, but also instills respect, knowledge-sharing, and mental and physical improvement. Effective movement, use of the opponent’s force, disbalancing and fluidity of motion in combination with proven techniques yields maximum efficiency.

We teach throws, takedowns and ‘sutemis’ (sacrifice throws), joint locks and submissions on all mobile parts of the body and strangulation techniques. We teach standing-to-ground transitions, ground fighting, pressure points, and striking using all natural body weapons. The combination of all of these is an integral concept.

Training is defensive and employs counter-attacks against short or long distance aggressions. Defense against one or more potentially armed opponents is also considered. We rely on repetitive practice of each technique (‘uchi komi’), free sparring and attacks of various styles and intensities, with or without a ‘gi’ (training uniform). It is a harmonious and efficient discipline, fluid, rapid, powerful and functional: this defines Nintai Ryu Aiki Ju-Jitsu. 

Emblem of Nintai Ryu Aiki Ju-Jitsu

Our emblem does not represent our way in its complete form but points to its origins.
The cherry flower symbolises judo where everything began for us.
The mountain represents Mount Fuji, the emblem of Master Minoru Mochizuki and Yoseikan Budo. This is the school that brought us to the way of Aiki Ju-Jitsu.
In the background there is the emblem of Daito Ryu, the ancient school of the Takeda Family.

The blue water evokes the phrase of 'Mizu no Kokoro', which may be translated as the spirit of water or spirit like calm water. This may be interpreted as: fluidity of movement, facility of adaptation like that of water, the power of water, tranquillity of the spirit at the impact of an action, relaxation of the body to achieve greater efficiency since troubled water distorts the visions it reflects.

The word Nintai means perseverance or endurance. This may be understood as perseverance in effort, in the quest for knowledge, in training and, finally, in the improvement of body and spirit.
