Those of you that know me know that I have a fondness for my own personal, very colloquial translations for Japanese names of techniques. Well, here's one you might enjoy. The jodo kihon named kuritsuke, I call "Rooftop and Letter-C." The rooftop part of it corresponds to something like a rising block or deflection. The Letter-C corresponds to a sweeping arc downward from the rooftop position to waist level that can be used to trap or throw.
The other day I had a student comment that the motions in jodo and aikijo seemed to be esoteric and crazily precise - so specialized as to be virtually useless for anything but jodo kata. So I bet him that I could do all of Tomiki's Junanahon Kata using only rooftop and letter-C motions (with or without a jo). This is pretty cool and fun and I bet if you take just a moment or two, you can figure out how to make this work...
- shomenate - enter to the inside and rooftop, striking under uke's chin (with end of jo or with your hands)
- aigamaeate and gyakugamaeate - rooftop under uke's elbow, pushing elbow into head with a letter-c
- gedanate - rooftop, step outside, letter-c striking uke's flank
- ushiroate - rooftop - step outside, letter-c striking uke from the rear
Turns out that it doesn't take too much extrapolation to make all of Junana work using only rooftops and letter-c's. I think my student was impressed and this demo piqued his interest in both jodo and aikido. Try it... Enjoy.
