Re: Kokyu explanation
kokyu literally means breath. To me most of the techniques are achieved by controlling breath, breath in as you come in contact, and breath out with ki-ai and you throw. In addition to that your body position has to bring uke to a point that they are off balance, same as most techniques, but there is no kansetsu waza (like nikyo, sankyo, kotegaeshi). It doesn't hurt, uke is just off balance and must fall. Many people say that when a technique doesn't have a name, it's just kokyu waza.
