Continuously, rotate the left wrist outwards, take hold
of Ukemi’s wrist and do a hikite on the left hand,
pulling to the hips. At the same time, move the body
forward and ‘stab’ next to Ukemi’s face. This could
be atemi as well. Make sure to break Ukemi’s posture
and weaken or release the grip. Ukemi should keep
trying to maintain the grip. Letting go should result
in receiving a blow.

Contact the side of Ukemi’s face with your right hand,
twist the body to the left and push Ukemi down. Don’t
just pull behind the neck, because then Ukemi can slip
out easily. It is actually a combination, so you should
push Ukemi’s face to the right while pulling behind
the neck. The left fist should maintain the grip, keep it
close to the body, where you are naturally stronger. Of
course, you could do atemi. That is hidden however.
Still maintaining the grip of the left hand, finish with
shuto to hana. Variations of Idori include a joint lock
to the elbow. In our regular practice this is hidden.
Ishikawa sensei used to say that every movement in
kata contains hidden movement. He was referring to
techniques that where either not performed in regular
practice or ohyo of the techniques performed. Hence,
he also used to say “anything is possible”. The usual
explanation for using shuto is that it symbolises a
short sword or dagger that samurai carried and used
in the old days. According to Sakagami sensei, it is also
“hin”. Hin means grace. “Hin ga nai” is not graceful
or not polite as you insult or embarrass the one on
the floor when using a fist to finish, or even worse, to
pretend to stamp on him. Of course, practically that
would be quite effective. However, we have to keep in
mind that our eventual aim is to create peace and that
we should learn how to behave properly in society.
