外受けSoto-uke — Outside forearm block

Soto-uke (外受け, “outside block”) swings the forearm from outside inward to deflect a mid-level attack across the body, blocking with the little-finger edge of the forearm. In JKA Shotokan it is named for where it comes from — the hand starts up by the ear — the reverse of some other styles’ labels.

Toggle between the phases. These are simplified schematics of the shape of the technique — pair them with the step-by-step below and your instructor.

A diagram shows the shape, not the speed or feel. For full-motion form, watch the reference video below and train it live.

How to perform it

  1. Chamber the blocking fist up beside the ear, elbow high and pointing out to the side.
  2. Swing the forearm down and inward in an arc across toward your centre line, dropping the elbow as you go.
  3. Rotate the forearm so the little-finger edge meets the attack, completing the rotation only at impact.
  4. Retract the opposite hand sharply to the hip (hikite) with about a 45° hip rotation for power.
  5. Finish with the forearm roughly vertical at the centre line, fist at shoulder height, elbow dropped to cover the side.

Key points

  • Travels outside → inward; contact is the little-finger side of the forearm.
  • Drop the elbow as you block to cover the ribs.
  • Keep it compact — a hip-driven deflection, not a wide windmill.

Common mistakes

Keeping the elbow high through the swing, exposing the armpit and ribs.
Swinging too far across past the centre line.
Rotating the forearm too early and landing on the wrist.
Turning it into a wide windmill instead of a tight deflection.

Where you’ll see it

Application (bunkai)分解

It sweeps a mid punch across and past your body, turning the attacker slightly and opening their flank for a counter with the retracting (hikite) hand.

Note: applications are interpretive and one shape carries several valid uses — explore them with a qualified instructor.

Soto-uke — frequently asked questions

What is the difference between uchi-uke and soto-uke?
In JKA Shotokan, soto-uke travels from outside inward and blocks with the little-finger side of the forearm; uchi-uke travels from inside outward and blocks with the thumb side. Same target height, opposite motion and opposite blocking surface.
Why is soto-uke called an outside block if the arm moves inward?
It is named for where it comes from — the hand starts outside, up by the ear. Styles that name by direction of travel (Wadō-ryū, the JKF) use the opposite label, which is the source of the confusion.
Which part of the forearm blocks in soto-uke?
The outer, little-finger-side (ulnar) edge of the forearm.
Is Shotokan’s naming backwards from other styles?
Relative to Wadō-ryū, Uechi-ryū and the JKF, yes — those name these blocks by direction of travel, so their labels are swapped versus JKA Shotokan. Same techniques, opposite names.
