Bujinkan Dai Shihan


5th April 2023

Eight newsletter. It's been a while since the last newsletter, not much has been happening. I decided that the theme I like to focus on this year is Shindenfudō-ryū and the Kusari-fundō.

In March we completed the first level of Shindenfuō-ryū Dakentaijutsu Ten no Kata or Iken Hassō. The video is available at BUDOSHOP.SE.

Now we move on to the second level, Chi no Kata or Biken Isshun.

I just finished an article about the three different timings in traditional Japanese Budo and the Neuroscience of free will. I had some help from the machines and it turned out better than i expected (we are doomed). Check it out here.



Please help me make this a better resource for everyone practicing the Bujinkan Martial Arts. Contribute and help grow this newsletter by sending me news, seminar advertisements.

Martial Arts and the Neuroscience of Free Will

I will try to explain Japanese martial arts and the Neuroscience of Free Will in this article. The three approaches of Go no sen, sen no sen, and sen sen no sen have been used for centuries to develop effective strategies for both offensive and defensive manoeuvres.

However, the scientific study of human behaviour has challenged our traditional understanding of free will and decision-making, calling into question how much control we have over our actions. In recent years, advances in neuroscience have shed new light on the nature of free will and how these martial arts concepts may relate to it...

I've had the BUJINKAN.TV domain for a while now but didn't know what to do with it.

New video since the last news letter is...

I have only written one public book, and it is the YUDANSHA book. I got very good feedback from many prominent Bujinkan teachers including Hatsumi Soke. The book covers all the Taijutsu techniques I think every 5'th Dan should know by heart.

The book is only available from Lulu!

Below is two pages from the book as an example. It is available in a few different formats and bindings.

Master One To Master All

At the end of the class, Nagato sensei said, “if you master one thing, you can master anything”.
It reminded me of how Musashi became a fantastic painter after mastering the art of the sword. (1) In his famous book “Gorin no Sho”, he writes, “When I apply the principle of strategy to the ways of different arts and crafts, I no longer require a teacher in any domain.”

Encounter With A Polisher

The Japanese Dai Shihan show how to polish our movements; I call them “polishers” for that reason.
My younger son Amaury is 27 years old, and this is his first Japan trip. Entering Nagato sensei’s class, he had the time of his life as he was his uke for the course. Being the son of the polar bear, it was obvious that Nagato sensei would use him as uke. I should have told him in advance, but somehow I forgot (am I a bad father?). This trip was supposed to be in 2019, but I had to go to Lebanon for a few months, and then the confinement hit us all.

Kannin: Keep Going!

With my brother-in-arms Pedro, and a few others, we had the chance to share lunch with Sensei. During this time, he said, “this year, the important is Kannin, keep going.” (1)
There are several meanings to Kannin. Kannin refers to a period in Japanese history at the beginning of the 11th century (1017-1021).
We collected nearly 2000 articles and essays from the most well known Instructors of the Bujinkan Dojo since 2005.
