Sumo techniques often involve subtle movements that aren’t easily understood at a glance. One such movement is “ude wo kaesu”, a fundamental action frequently used during bouts. This article offers a clear and accessible explanation of this technique—its purpose, meaning, and practical usage—so that even sumo beginners or international fans can appreciate its significance.

What Does “Ude wo Kaesu” Mean?

Basic Definition and Movement

Ude wo kaesu” refers to the action of twisting one’s arm inward after grabbing the opponent’s “mawashi” (belt). By doing so, the rikishi (wrestler) pulls the opponent closer to their body, gaining control and preparing for a decisive move.

This subtle twist allows for efficient transfer of power from the arm to the opponent, enabling the wrestler to align their whole body for an effective technique. Although it may look simple, this motion is a critical aspect of sumo that wrestlers refine through daily practice.

The Purpose of “Ude wo Kaesu” in Sumo

The movement serves multiple tactical functions and is far more than just an arm motion.
