Tani Otoshi Reference

Mat Manual companion guide to "Tani Otoshi: The Throw Behind You." Print it. The article teaches the valley drop and names its safety spine: the knee line. This book is the working reference. It carries the technique card with the knee-safety standard printed on it, the ukemi gate as a pass/fail checklist, uchikomi variants that drill the line behind the heels, counter-entry progressions timed to a partner's failed forward throw, and a twelve-week landing plan.

Player: ______________________________ Club: ______________________________ Coach: ______________________________ Stance: ☐ Right (migi) ☐ Left (hidari) Partner stance tonight: ☐ Ai-yotsu (matching) ☐ Kenka-yotsu (opposite)

BEFORE ANYTHING: SCOPE AND SAFETY ☐ THE KNEE LINE RULE, PASS/FAIL: tori's body and leg drop behind uke's heels, into empty space, only after uke's weight is already moving backward. Nothing lands across, on, or through uke's planted, loaded leg. A rep that breaks this rule is a failed rep and stops the set, whoever threw it, however clean it looked. ☐ Ukemi gate before throws: uke receiving tani otoshi must pass Part 3 (back fall and backward side fall checked, chin tucked, no straight posted arm) before the first full rep in this book. Pass or fail is recorded, not assumed. ☐ Tori keeps uke's sleeve through every landing, drilling speed included. An unguided backward fall is a failed rep in this book. ☐ Many rooms gate this throw for beginners, and some competition contexts restrict sacrifice throws or their leg positions. Your coach's room rule governs in your room; your event's current ruleset governs at your event. Both are checked in Part 25, not guessed. ☐ Mat awareness: uke falls backward from their position. Check the space behind uke before every set. ☐ The stop word ends any set instantly, from any player, for any reason. Cause is logged in Part 24.
