Uchimusō

Uchimusō is an official sumo kimarite in which a hand sweeps upward against the opponent’s inner thigh while the upper body is twisted down. The clearest cue is that the low hand works from beneath the inner thigh as the torso turns. Uchimusō attacks inside the thigh; Sotomusō works against the outer knee. The practical English gloss “Inner thigh sweep-down” is a viewing aid rather than an official translation. Focus on the contact that causes the final movement and on whether the opponent is forced out, falls, or is thrown. Earlier exchanges may create the opening, but the kimarite names the action that actually decides the bout.

Name
Uchimusō is written 内無双 and read うちむそう. It belongs to Twist-down techniques (捻り手); “Inner thigh sweep-down” is a practical English guide, not an official translation.
Context

Statistics
The Japan Sumo Association table consulted on 12 September 2026 counted 59 Uchimusō results, 0.03% of 190,450 bouts from January 2013 through the final day of the July 2026 tournament, and listed the technique 47th in that bounded dataset. This is a dated sample, not a timeless probability; check the association’s live page for later totals.
