Aikido 'Sumi Otoshi'- Really???

What you're describing is the physiological weakness of standing on two legs, regardless of what stance someone may be in, there's a weak spot.

In Japanese its called sankaku, most commonly "triangular", the human body forms two points of that triangle which can be drawn from any stance, the weak spot is the third point. Naturally that point moves whenever the stance moves. The skill, is application of movement creating kuzushi exploiting that weakness.

If done correctly, your "technique" becomes the biggest atemi when the unfortunate party makes contact with the ground.

Think about that. Think as if ukemi doesn't exist.

So my judo is a great striking art if I throw properly? Damn Hugo, that's some Musashi stuff right there...:laughing7:laughing7:laughing7

..Because it's not the fall which hurts but the sudden stop when you hit the ground.

Ukemi on tatami isn't the same as being dumped on the pavement.

Superbly put. I shall make a point of remembering this explanation. Thanks.

Eddie, if you take a close look at Japanese weaponry exponents, you'll see that they tend (if they've been well trained) to avoid raising their hips as they move, it's that lifting of the hips which makes entry into their posture very easy, the hard part is recognising it.

Sankaku is both a form of stance with the feet (creating that "T" shape between the rear and front foot) and also where the weakness is when you look to exploit it.

Thanks to you and Dave.

I have heard it demo'd and explained before by a Judo 3rd Dan (and JJ high Dan) when he was going through Kuzushi No Kata (apologies if I've mis-stated that) and it was also later alluded to by his instructor.

It's just that Dave's explanation was the best I've read/heard.

Grateful for the addition re Weapons. I'll keep that in Mind as well(!)

Cheers both
