Overview
Yoko Wakare, the side separation throw, is a sacrifice technique in which tori drops to one side while maintaining a strong grip on uke, using the sudden separation of tori's body from the standing position to pull uke laterally off balance and over tori's body. [1],[2] The 'wakare' (separation) refers to the splitting action as tori's body drops away from uke while the arms maintain the connection. [1],[3] Yoko wakare is effective against opponents who resist lateral movement and can be applied as a counter to hip throws when tori is being attacked. [3]

Biomechanical Mechanism
Primary Action — Loading the opponent onto the hip and rotating them over it — the hip acts as the fulcrum
Joints Involved — Attacker's hip (fulcrum point), knees (deep bend for loading), core (rotation), opponent's centre of gravity (elevated)
Force Vector — Rotational — pulling and turning motion loads the opponent, then hip extension and rotation drives them over
Kuzushi (Off-balancing) — Forward and upward — breaking opponent's posture forward lifts their centre of gravity onto the attacker's hip
Position & Entry
From judo grip — Break the opponent's balance forward (kuzushi), turn in with hip below their centre of gravity, and rotate to throw
From clinch (overhook or underhook) — Secure inside position, turn the hips across the opponent's body, load and throw

FIAS Combat Sambo RulesPDFTraining Notes
✓Yoko wakare (side separation) combines a turning entry with a side sacrifice — you turn in as for a hip throw then fall to the side to complete it (Mifune, Canon of Judo, 1956)
✓Enter as for a forward throw, but instead of completing it standing, fall to the side while pulling uke over you
✓Your body falls across uke's path — they trip over your extended body
✓Yoko wakare is useful when your hip throw entry is blocked but you've already committed to turning in
✓Maintain strong gripping throughout — the turn-in plus side fall must be connected through the arms
✓This throw transitions well to yoko shiho gatame (side four-corners hold)
✓In competition, yoko wakare often appears as a transition from a blocked seoi nage or hip throw attempt
Common Mistakes
!Turning in and falling without pulling uke — you end up on the ground with uke standing
!Not turning in far enough — the entry must be deep enough that uke is loaded before you sacrifice
!Falling straight sideways instead of across uke's path — your body must block their movement
!Releasing the grips during the transition from turn-in to sacrifice — maintain continuous tension
!Not extending your body to maximize the tripping surface — stretch long across uke's feet
!Attempting without a genuine initial throw entry — the sacrifice only works because uke is defending the standing throw
!Landing on uke's legs or feet — fall beside them and pull them over
