Training notes: Katatedori sumi otoshi

Otoshi (or drop) techniques feature prominently in a variety of martial arts, including Aikido, Judo and Jujitsu. Otoshi techniques are typically thought of as “hand throws” and when applied correctly generate a surprising amount of power that literally has the effect of dropping (some might say “driving”) the uke straight into the mat.

Ueshiba 5Sumi otoshi (corner drop) is probably the most common drop technique practised in Aikido. The particularly appealing features of this technique include its directness in execution and the fact that it is able to be used to in response to a wide variety of traditional attack situations.

However, while sumi otoshi looks deceptively simple on its face, in reality it requires considerable skill to apply  with any degree of martial integrity.  For example skills in kuzushi (i.e. off-balancing), timing, moving off-line and centred movement are essential.

In the below video, Mike Jones Sensei from  New York Aikikai provides instruction for sumi otoshi from an attack in the form of a same side hand grab (Katate dori).

 

ADDITIONAL NOTES

  • Alternate application

Donovan Waite Sensei (7th Dan Aikikai) in the following video demonstrates and provides training tips for an alternate application of  katatedori sumi otoshi, as well as the variation in the featured video.

 

  • Learning ukemi

In every technique ii is important to learn not only how to execute it, but also how to safely receive it (ukemi).  In the below video, Waite Sensei demonstrates how the nage can assist the uke in safely learning ukemi for the sumi otoshi.
