Training notes: Ryotedori seoi otoshi

While by no means the most commonly practised “drop” technique, seoi otoshi (or “shoulder drop”) has been part of Aikido since its early days.

In the below video, students from our dojo are practising the technique from a traditional where both of the nage’s wrists are grabbed (ryotedori). This form of practice is excellent for ukemi training and developing aerobic fitness for the nage.



  • Technical notes

In the following video Peter Kelly Sensei of Aikido Yuishinkai (Tasmania) provides technical instruction for the technique.



  • Ryotedori kokyu nage

The set up for ryotedori seoi otoshi (as demonstrated in the video) is the same as for ryotedori kokyu nage.  For notes on ryotedori kokyu nage (including its set up) – see Training notes: Ryotedoru kokyu nage (and koshi nage).

  • Difference between seio otoshi and seio nage

Seio otoshi - Ian Grant SenseiThe difference between a seio otoshi (shoulder drop) and seio nage (shoulder throw)  is often a source of confusion. For discussion on the technical differences between the two technique types see – Seio otoshi and seio nage – Whats the difference?

Have a great week.

Training notes: Ryotedori yonkyo

Yonklyo - Peter Kelly SenseiIn the below video, Peter Kelly Sensei, Chief Instructor Aikido Yuishinkai Australia, provides instruction on how to perform ryotedori yonkyo.

A key aspect of Peter Sensei’s instruction is the notion that yonkyo (No 4 wrist technique) is not at its essence intended to be a technique to control a uke by inflicting wrist pain.  Rather it is a method of hyper-extending the uke’s shoulder to control their centre.

Training notes: Ushiro ryotedori kokyu nage

In the below video Morihiro Saito Sensei  demonstrates and provides instruction for the pre and post war versions of the aikido technique ushiro ryotedori kokyu nage.

The technique is  categorised as a “breath throw” and is practised as a response to a traditional attack where both hands of the nage are grabbed from behind with the intent to either place a knee in the nage’s back or drag the nage backwards.

Depending on the school of Aikido the technique is sometimes referred to as ushiro tekubidori zenpo nage/kokyu nage.



  • Alternate attack form

Ushiro ryotedori kokyu nage, like all Aikido applications, can be practised from a static form (typically under resistance) or in a dynamic free flowing form (often referred to as ki no nagare). 

In the following video, the Founder of Aikido, Master Morihei Ueshiba (O’sensei) demonstrates a dynamic version of  ushiro ryotedori kokyu nage  whereby the uke directly attacks from behind and out of the nage’s line of sight (see video below).  We also train this version at our dojo.


  • Alternate application

In the below video Sensei Andy Hathaway of the London Aikido Club demonstrates an alternate kokyu nage application.


  • Ki aikido approach

In the below video the Koretoshi Maruyama Sensei demonstrates and teaches the subject technique as practised in Aikido Yuishinkai. This approach (including the bounce) is typical of many ki aikido schools inspired by the teachings of Koichi Tohei Sensei.

Have a great weekend.

Ryotedori taninzugake demonstration: Master Koretoshi Maruyama

Maruyama Sensei - advanced techniqueIn the below video, Master Koretoshi Maruyama, Founder of Aikido Yuishinkai, gives a demonstration of ryotedori taninzugake.

In our School, taninzugake (or free form practice) is commonly practiced at the end of each class.  This type of practice allows the nage to respond to the selected attack type by using any technique they so choose.  The attack type in the video is ryotedori, which is a 2 hand wrist held from the front.

Ryotedori taninzugake forms part of the Aikido Yuishinkai grading syllabus for 1st kyu (brown belt) gradings.

Training Notes – Ryotedori kokyunage and koshinage

Peter KellyThis video training note examines ryotedori kokyu nage and koshi nage applications.  The video extract is from from a class given by Peter Kelly Sensei (7th Dan, Aikido Yuishinkai) at the Aikido Warrior Dojo on 17 May 2014.

Peter Sensei’s interpretation of koshi nage (hip throw) is heavily influenced by the approach taken by Yoshio Kuroiwa Sensei. Peter Sensei makes the following comment in this regard:

Yoshio Kuroiwa Sensei always taught with a stick to teach lines and internal power vectors and triangulation. He was very martial, an ex boxer. Great understanding of movement. I have tried very hard to follow his style of Koshi. If it’s easy and smooth, no can defence.”

In the video extract Peter Sensei notes that O’Sensei often joked that he could do koshinage all day and not get tired.  The ukemi challenges associated with koshinage are also explored.
