Training notes: Ai hanmi katatedori nikyo

nilyo 2Nikyo techniques involve the application of a painful pronating or adductive wristlock to subdue or pin an attacker.  They are a common feature in the syllabus of most Aikido schools.

Nikyo techniques can be used to address a wide variety of attacks.  They are particularly effective in circumstances where the uke attempts to grab the clothing or wrist of a nage (as a prelude to follow up strike).

Our dojo is a Fudoshin dojo operating under the guidance and mentorship of Chicko Xerri Sensei 6th Dan AKI (Aikikai).

In the below video Chicko Sensei  explains the sword movements and Aiki principles  which underpin the application of Ai hanmi katatedori nikyo. This form of nikyo is applied in response to an attack in the form of a cross hand grab.

Depending on the school, Ai hanmi katatedori nikyo is also referred to as Kosadori nikyo.

  • Brief Biography – Morihiro Saito Sensei (1928-2002)

saito_seiza_260Morihiro Saito Sensei’s  practice of Aikido spanned 56 years and he is one of the most important teachers in Aikido history.  Saito Sensei was a live-in student of O’sensei for more than 20 years at his home dojo in Iwama, Japan.

Saito Sensei spent his teaching life dedicated to preserving the technical style of Aikido as practised and shown to him by O’sensei in the post-war period.  Without his commitment to preserving the Aikido of the Founder and extensive efforts to record and document his teachings, much of the Aikido of O’sensei may have been lost.

Have a great week
