What is the Jujutsu technique in which your opponent is forced to do a front flip?

Question

At least, I'm pretty sure it's a Jujutsu technique. It looks like a throw from sankyo (both standing position). If you could, try to explain how it's done.

EDIT: not tomoe nage or those type of throws... it's an arm technique. Your opponent will end up with his head at your feet on his back, you should be standing up facing him (if you've ever played Tekken 3+, this is one of Nina's basic throws).

EDIT: the first two techniques from http://www.youtube.com/watch?v=JIowy89IXco are it I think. Now I know how to do sankyo, but I'm unsure of how to manipulate uke's arm to force him to flip/roll. I hope it's not a strict Aikido "demo" technique, because I want to try this on people who don't move very well.

Answer 1

If you meant Japanese Jujitsu, Are you talking about a variation of the Kaiten nage in Aikido? There is also a throw from a sankyo hold while the uke is raised on his toes by the wristlock that falls under the category of Kokyu nage as well, the technique is performed with the same motion applied when cutting with a sword in a forward downward strike or a shomen uchi, it forces the uke to roll forward with the momentum or risk landing face first on the mat if he tries to resist.

Edit: Actually, I do believe the rolling happens only during demos to prevent injury to the uke. But it's a pretty useful technique to apply in a crowded area though, you get the guy on his toes in a sankyo and slam him face first into a table corner, a car hood or roof or any solid structure that's waist to chest high, you need to do it with a sudden snapping motion though so as not to give him time to react and use his free arm to brace himself against the impact.
