Well, only if you have better kokyu than the other guy. Although looking at it from the outside, that wouldn't matter. You could just observe the result and mutter "kokyu nage works". If it's not a kokyu nage, then perhaps it's a specialty technique (though hopefully imbued with kokyu to get the movement to work, or else forced through with normal strength), or else it's perhaps a strength throw (using some normal strength rather than kokyu power, and no particular technical finesse that would qualify the technique with a technique-specific name). All these would work, if the end result is all that is desired. They have different value for training of course. I would add that it might be better to not think so much of kokyu throw as a throw, but more on the fact that only kokyu is being used as opposed to kokyu and some technical arm and leg movements to mechanically increase the inital advantage severalfold. So, a kokyu throw would not necessarily be a throw, it might only result in a lurch or unbalancing, depending on the degree of kokyu development difference between the partners.
