Sumi Otoshi
隅落とし
Literally: corner drop
Corner drop, classified in aikido among otoshi techniques and sometimes among breath throws; a technique of the same name also exists in judo.
Quick Facts
⚠️ Common Mistakes
Common mistakes: dropping the partner straight backward instead of along the diagonal, trying to replace direction with force, and forgetting one's own step, without which the technique has nowhere to lead.
💡 Key Tip
Nehledej hod, hledej roh. Jakmile najdeš směr, ve kterém už partner nemá oporu, technika se udělá skoro sama.
About
Sumi otoshi (隅落とし), literally corner drop, is classified in aikido among the otoshi-type techniques and sometimes treated as a kokyu nage breath throw. In sport Shodokan aikido, the uki waza group is among the 17 core techniques, with front, corner and pulling drop variants; the English name corner drop matches the translation of sumi otoshi exactly. The same name and translation belongs to a separate judo technique, part of the fifth group, gokyo no waza, in the Kodokan's list of 67 throws. The two techniques belong to different arts and have their own classification. We have not been able to document exactly how sumi otoshi is performed in aikido.
