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.



  • Hand position – Initial shoulder extension
