Releasing the Power of 力を抜くChikara o Nuku

I was at a recent class at the Bujinkan Hombu dojo where Hatsumi sensei threw his opponents around all night. But mostly they were thrown. He emphasized, that he was not doing the techniques. How might this be possible?

He used a phrase "刀を抜くkatana o nuku, 力を抜くchikara o nuku." This has many layers but by dropping the power or the intention out of your technique it becomes effective. Even dropping the technique from technique. But there is a trick to this that many students of Sensei apparently neglect to understand.

Many people think they know what Soke means when he speaks. That night in class, one of Sensei's frequent translators came up to me and told me, "That's not what he said!" Meaning that the current translator had gotten it wrong. So then he explained to me what he thought Sensei meant.

I just listened to his explanation and didn't agree or disagree. I brushed this off as a personality conflict between translators. Or maybe it was due to the extreme difficulty of concise translation of Japanese in the dynamic environment of the Hombu. But when more people complained to me about the translation, I figured there might be more to this.

So in order to participate in the confusion, I will offer my own thoughts about what we were witnessing in that class. I haven't yet seen anyone offer the explanation I will make below. But maybe you all know this stuff already.

You cannot have 力を抜くchikara o nuku if you don't first have chikara. Otherwise there is no power to take out of the technique. One common way that I have witnessed Hatsumi Sensei and the other Japanese instructors do this is by going from  力を入れる chikara o ireru (using force, strength or exerting effort) to 力を抜くchikara o nuku.

I myself have had great results using this in my taijutsu. For a simple example, it is like the children's game of tug o' war. Two teams pull on a rope in the opposite direction. Whichever team is stronger pulls the other towards their side and wins. But when I was a kid, we thought it was great fun to 力を入れる chikara o ireru and pull with all our might, then quickly release the rope for 力を抜くchikara o nuku. Relaxing suddenly and letting go of the rope made the other team fall on their asses.

You will see this concept everyday in the Hombu as the uke seem to throw themselves.

So 刀を抜くkatana o nuku is something I have been practicing for quite a few years. I have a visualization that I use to explain the principle. To get the tip of the sword to the target in an effortless and quick motion, it is like releasing a bird from your hand and the bird flies directly to the target as if it is spearing a fish. But first you must be able to capture or hold the bird.

Hatsumi Sensei described this method of drawing to us that night. He said that with katana o nuku, you are not drawing the sword, you are letting it free from the saya (like my idea of releasing a bird). It is very dangerous, with this motion the sword will kill with no effort at all. The blade finds its target.

This is what I understood from Sensei's class that night. Other people who were there may have different ideas that are valid. I hope that sharing my thoughts helps you to discover your own understanding about our art.

Japan Report Four 令和5年

I start off my Japan Report Four video going to Hatsumi Sensei’s house and the Bujinkan Honbu office. I do this on every trip because this is how I submit my rank paperwork for my students. In the video I talk about my “secret” route to his house. I also recall past times when I could just visit and have tea with Soke. During my walk to his house, I review some of my notes from old classes with Soke. During one class he said 自分の第六感兼ねあいうち Jibun no dairokkan kane aiuchi. This is when you make your intuition match reality. Or, more directly, your intuition is combined with something concrete such as a strike. Later in that same class, Hatsumi Sensei said 意識をさせない Ishiki o Sasenai. He was telling us not to allow our opponents to sense our intentions. Don’t put out any intention for your opponent to read. I thought it was fascinating to think about dairokkan and the use of intuition while also hiding your intentions. Hatsumi Sensei’s classes were full of subtle lessons lik...

Japan Report Seven 令和5年

I began the morning in a hurry because I had to get to the dojo early. My days in Japan are very busy. I run and gun to fit in all of the classes, recording my video reports in between. And I still have to find time for food, laundry, sleep, as well as tourism and shopping.  Today I planned three classes, Furuta Sensei, Nagase Sensei, and Noguchi Sensei. But I didn’t have time to review my notes until the next morning in a cafe. The coffee sure helped. The FULL video review can be found here: https://www.rojodojo.com/japan-report-seven-reiwa-five/ The first class was at the Bujinkan Honbu dojo with Furuta Sensei. We began class wearing a lot of knives. He said you should wear at least 9 knives. He didn’t mean that literally but the number 9 implies an infinite amount. So you have the ability to respond or attack infinitely. He kept hiding behind the attack of his opponents. I learned this approach from him a few years ago during our study of 雲隠流 Kumogakure Ryū in ...

Japan Report Six 令和5年

I was invited to Furuta Sensei’s home dojo out in the countryside. He is very generous and picked us up from the train station. The only problem is that he plays a Lady Gaga CD on repeat during the drive. Furuta’s home dojo is very rustic with traditional tatami mats. He started training with ukemi and my cotton tabi really slid across the straw! His exploration of 基本八法 Kihon Happō is influenced by his study of 雲隠流 Kumogakure Ryū. As the next Soke of Kumogakure Ryū, he is hard at work learning and studying this school. And I feel lucky to be part of this journey every time I study with him. At one point he showed a detail of how to attack the 急所 kyūsho 血止 chidome and 血ダメ chidame. The name of this kyūsho means to stop the blood. Obviously this would incapacitate an opponent if you pull it off. But Furuta Sensei used a hooking strike into chidome to unbalance with one finger. The kyūsho becomes a 支点 shiten. The pressure creates a pivot or a fulcrum to affect the oppon...
