This is the #3 Bo kata in the Okinawan Kenpo Karate Kobudo system
Tsuisu no Kun Bo Ichi.   There is a second Tsuisu no Kun kata which is Bo #5.

Check out this video of Morihiro Saito Sensei from 1974. This may still be one of his most complete weapons videos. He had a myriad of boken (sword) techniques. Undoubtedly many from Morihei Ueshiba, O'Sensei, but probably still others that developed as he understood and saw more deeply into the techniques.

The second half of the video changes to empty hand.  I just saw something very interesting that has changed over the years but here it's shown differently.   Saito Sensei is doing a Sankyo technnique.   By the time I came along the footwork on the take back to get the main sankyo hold, people were teaching only 45 degrees turn back.  At about 33 minutes into the video Saito Sensei turns back 90 degrees just like Nishio Sensei taught.   So somebody changed things and nobody told Saito Sensei he was vulnerable to a flip when he changed to the 45 degree turn back.

This is a video of Nishio Sensei, almost certainly from one of the Aiki News Friendship Demonstrations from the 1980's. Stan Prannin is narrating so it's definitely Aiki News video.
There is a lot of the typical good stuff, but the koshi nages were pretty rare by the time I got there in the 1990's. The average age was in the 40's - 50's with some people up into their 70's in classes regularly. They can't afford to take such falls, so these became pretty rare during regular classes.   This video also displays some of Nishio Sensei's blindingly fast weapons movements.  It has taken me a long time to realize how this is accomplished other than just copy, but now I think it can be rationally explained.   The movements are not achieved in the same manner as other weapons practices. 
Most of the time when Nishio Sensei would demonstrate koshi nage he would take his moving foot in front of the supporting foot and he would step out and away before turning back to uke. I thought this was the norm, but I had terrible trouble with my foot going behind my supporting foot. As I started to understand more about the throw, once or twice I did notice his foot went behind his supporting foot and he came out facing down on uke.  (This is actually what takes place in this video.) When I realized either way was OK, I was able to relax and start to send the moving foot the direction I desired it to go.
This koshi nage is quite different from the normal Iwama and (I think) the normal Hombu style hip throw.  I think the hip throw is becoming rare in the Hombu style.  Perhaps to many hard falls for the ukes.  When uke is loaded in Nishio Sensei's form, uke's body is supported at first, then you have the feeling that the floor dropped out from under you and you flip and end up on the mat.
What is happening is, the hip away from uke drops away as the moving foot, the foot away from uke, moves across past the foot that is in between uke's feet.
It takes practice, but this can become a very fast throw.  Unfortunately I rarely get to practice this throw in this style.   In the manner that Sensei is demonstrating in this video, uke is powerless. with both hands held and he is just along for the ride. It's a fun ride as long as you land OK.
The koshi nages show up at about 2 minutes.
The uke at that time is Yasuhiko Takemori Sensei.  He is so young here.  Maybe still in college.  I trained with him on Thursday nights at Fukaya dojo and later at Okamoto dojo after the Fukaya dojo closed.  Takemori Sensei taught when Nishio Sensei was not there and on Sunday evenings regularly and I also learned Iaido from him on Saturday mornings in Anjin Zuka when the USS Independence was in port. He is at least 7th dan maybe 8th dan now in Iaido. Here's the youtube video site:

Hey Folks, 
We have a new TV commercial running on the Gainesville Television Network.  It's running on the older shows channels.   It's made up of pictures, but the production people have been able to make it appear to be moving.
This is the link.

I uploaded a video showing a technique using a walking staff. The Iwama Style of Aikido does this technique, but the hands and feet do not move the same as empty hand execution. This video that I made shows nearly identical hand and foot movement compared to the empty hand execution.

Published on Oct 30, 2015This video shows how I have utilized Nishio weapons integration concepts in an Iwama Style Sankyo. The hands and feet move the same as the empty hand application. Keith McInnis served as Uke.

Today has been a GREAT! GREAT! Day!!! After teaching 41 kids up in Alachua at the Bhaktivedanta Academy, I had 4 in the kids class at the dojo. What made today special was assigning the 6 year old Snr (purple with white stripe belt) to teach 7 year old Jkn (purple belt) a technique on Snr's blue belt test which is introductory on the purple with a white stripe test. I also had 7 year old Smn (purple belt) teaching 6 year old Ansl (white belt) techniques on the yellow belt and purple belt tests. The yellow belt test is basic rolling and wrist technique warmups. The purple belt test is the anti bully techniques test. Beginning students start out automatically as white belts.

That sounds like Greek, so I'll explain. Almost all techniques have something like a forward and backward form. I set the tests up so students have simple forward and back techniques with higher, more complicated techniques shown in the easier form on the back end of the test. Then the next test will have both the forward and backward of the techniques introduced in the previous test and even more complicated techniques on the back end of the next test. I tried to have this pattern continue through the curriculum, until they have most of the basic techniques plus various new attacks on previous techniques.

Teaching causes the student to explain techniques which forces them to think more about what happens in a technique. Another benefit, this requires real “SELF” discipline to think, explain, do and to receive the technique (take the fall) for the student being taught.

I have had kids teaching kids before, but always older teens class students. Today the 6 year old, who just turned 6 in July, was teaching the 7 year old. That's a WOW! Terrific! He is so sharp!

Another benefit today was Smn teaching Ansl. Smn missed promotion on her first try at purple belt cause she had trouble remembering techniques. Today caused her to focus more and think to teach Ansl. This also gave Ansl interaction with another girl, which was good for her and she learned a lot.

      Wow, I didn't realize it has been so long since I posted on this page. 
      Last Sunday, June 7th, we had a 3 hour demonstration/game playing session at Trinity United Methodist Church with Fun 4 Gator Kids.   It was mainly water stuff for the kids.  This was the Fun 4 Gator Kids School's Out For Summer Bash.   We didn't demonstrate as much as I was intending cause it was a more fun for the kids type day.   We showed them and let them play some of the main games we play at Aikido of Gainesville.  
   
    The kids loved playing the blind swordsman game that we have named Zatoichi.  There are lots of Japanese films and perhaps a seris of TV shows about a bind priest swordsman who goes around ridding places of bad guys by whacking them up.   Since it was outdoors and lots more sounds that made it hard to sense who was around the blindfolded person, we made it like the pool game Marco Polo.  When the blinded person said Zato, everybody else had to answer ichi.   It worked well and the kids had a ball with it. 
We had them using using a 2 1/2 foot pool noodle as the sword.

Luckily we had brought two of the pool noodles, so we let them have mock sword fights.   I refereed and stopped them at 10 strickes.   They had a ball with that game too!

Near the end we got some Aikido and weapons taking demonstrated.  I didn't notice when I was demonstrating that all kids were oohing and aahing when I took somebody in a high fall.  

It was a good day!
