Sumi Gaeshi Playbook

Mat Manual companion guide to "Sumi Gaeshi: The Corner Throw." Print it. The article teaches why the corner, the grip order, and the gate decide this throw. This book trains them: grip-entry cards with the over-the-back version first, lift-leg placement drills, direction-reading progressions fed at three postures, landing grades, and follow-through standards that build on the throw-to-ground work rather than repeating it.

BEFORE ANYTHING: THE UKEMI GATE IS PASS/FAIL ☐ Uke's falling for this throw is reliable before uke receives a full sumi gaeshi: the diagonal travel fall or roll your club teaches, chin tucked, no straight arm posted into the mat, shown at speed. Pass or fail. No percentage version. ☐ Tori's own drop, roll, and recovery falling are reliable before tori throws at full travel. ☐ The flight path to the corner is clear of other pairs, walls, and mat edges before every drop. The check is spoken in early drilling. ☐ Grip before drop, every rep. A hand reaching for the back after the sit has started ends the rep. ☐ Tired drops are collapses and uke pays for them. The dose caps in Part 17 are safety rules. ☐ A partner who has not passed the gate trains entries, grips, and fit-ins only. Nobody leaves the ground in their reps. ☐ Room, school, and event rules on sacrifice throws govern. Where they restrict the throw, the throw waits.

Part 1: The Technique Card

Safety printed on this card because it belongs on every card in this book: no full throw exists in these pages without the Part 2 gate, clear space, and a receiver whose falling has passed.
