This video showcases Japan’s Masashi Ebinuma and his mastery of ippon-seoi-nage, one of the most spectacular and effective techniques in judo. From his classical lapel grip entries to his devastating deep step variation inspired by Toshihiko Koga, Ebinuma demonstrates how to break balance, generate maximum projection, and adapt to different gripping situations. Featuring slow-motion breakdowns, technical analysis, and competitive examples from World Championships and World Judo Tour events, this is a complete study of ippon-seoi-nage at the highest level.
