Overview
Standard Yama Arashi executes the classical mountain storm throw where the thrower grips deeply at the opponent's lapel or collar, turns explosively, and drives the opponent forward and over while dropping the body to generate maximum rotational force. [1] The deep grip allows the thrower to control the opponent's posture and direction throughout the throw, while the body drop adds falling-body-weight force to the arm action. [1],[2] The technique produces a powerful, high-amplitude throw when executed with full commitment. [2],[3]

Effectiveness
Yama arashi (mountain storm) is a powerful sacrifice-style arm throw that generates tremendous rotational force through the combination of a cross-grip pull and a sweeping leg action. [1] When executed with commitment, it produces devastating ippon-scoring throws, though the cross-grip entry makes it difficult to set up in modern competition. [2]
Lineage
Yama arashi holds a special place in judo history as the technique used by Shiro Saigo to defeat opponents in the famous 1886 Tokyo Police Tournament that established judo's reputation. [1] It was included in the Kodokan nage-waza system as a te-waza technique. [2] Some historians debate whether Saigo's technique was true yama arashi or a form of uki goshi, but the technique's association with this foundational moment in judo history is firmly established. [3]
Competition Record
Yama arashi is rarely scored in modern competition but remains in the Kodokan syllabus. [1]

βFrom a deep lapel grip and sleeve grip, drive into the opponent with a step forward
βTurn into the opponent as if entering a seoi nage but continue the rotation into a forward sacrifice fall
βAs you fall, pull the opponent over your body using the deep grip and arm lock action
βThe opponent is pulled over and around your falling body, landing on their back
βThe fall and the throw must be one continuous motion β enter, turn, fall, pull
βMaintain the grips throughout to control where the opponent lands
βThe throw is complete when the opponent is rotated over your body to the mat
Common Mistakes
!Entering without the deep lapel grip β yama arashi depends on the deep grip for control
!Separating the entry and the fall into two actions β they must be seamless
!Falling forward onto your face instead of rotating to your side or back during the sacrifice
!Not pulling the opponent over with the arm action β the fall alone does not throw
!Releasing the grips during the fall out of instinct
!Over-rotating and ending up in a worse position than the opponent
!Not breaking the fall safely β practice ukemi specifically for yama arashi's falling pattern
