Tonight Sensei taught at the church, and because it was packed he showed some creative waza. This was one of them.

Using ki-no-nagare, as Uke comes in to grab your extended wrist (gyaku hanmi katatedori), you slide outside off the line of momentum and do sotomawari. How long you do this up to you, but a very quick one is sufficient. A more generous one is graceful and good partner practice.

When you feel comfortable, stop the mawari, readjust your trajectory and plant your back leg to do a surgical nikyo with aim at Uke‘s hara.

However, do not take Uke all the way to prone as you would normally; take him to the point where he is just starting to go down, brush his nikyo‘d arm down and back as if to do kaitennage osae, but slice your closest arm under his bicep, past his armpit and almost gliding over his shoulder blade with an extension. Your armpits should almost be in contact.

Because you were in good nikyo stance and your groin is protected, at the same time as you are doing the above extension, slide in (not step) so that your bodies are in close contact and your mijiku become one. With a kokyu, slide forward and take his balance and send him tumbling.

This could be a kokyu finish, however you are using your hips for the throw. If you rotate your hips as you throw then it really emphasizes the koshinage nature of this waza.
