Learn to control stress and fear

Use our ground breaking Detant course and learn to be clear headed, focused and determined in extreme situations. Use our unique physical emotional modulation. Proved in battle and in the daily grind of the Israeli situation.


AKBAN is a Martial arts research institute that was founded in Israel and has dojos in Israel, Germany, Canada, Greece and soon, in Japan. Yossi Sheriff is the AKBAN Academy headmaster. Our veterans have decades of experience.

Extreme training regime is augmented by the conflict managment tools and unique power control techniques of DETANT.

We train the way we like by absorbing ourselves in Japanese Ninjutsu techniques while fearlessly researching. We don’t care about politics, political values, belt systems or Mc-dojos – what matters to us is dojo time, heart and earth, that’s it: One principle – There are No shortcuts, but there is Kwisatz Haderach.

This site is a part of our Slow web philosophy. In it you will find more than 7000 pages of techniques and videos and also our gradual fitness routines – take your time, return to reread or mail us (akban [at ] akban.org) for research oriented issues. Scroll down, and on this page you can read the last week’s sessions, because that’s what we focus on – plain old practice.We are The AKBAN academy, we preserve ancient knowledge of fighting, awareness and desert navigation by practicing it. on our list of publications is research in conflict methodology and analysis of traditional and modern fighting techniques. Our think tank resulted in unique research and was the cornerstone of the DETANT organisation for public sector conflict resolution.Sparring is in each and every lesson and so are yearly seminars with some of the world’s best teachers in Boxing, BJJ, Muai Thai, European martial arts and more. On our dojos are only 300 practitioners each year, and they take at least 12 years before a black belt. So, since 1986, we graduated only 100 black belts.  

This site is our dedication to what we love: the warrior culture, and all this is free, our respect to you.

The Academy’s headquarters is situated in Tel Aviv, and another office is in Jerusalem. We have graduate instructors all over Israel, working in small, sparring oriented, dojos. Our recent dojo addition is in Toronto, Canada.

It is not easy to say what makes the Akban community so robust; is it the Israeli situation, the top notch fitness? Who knows? We believe part of it is the special kind of students who choose training with us, students that get involved in incredible achievements and continue training for a lifetime. As we said, we are not sure, but we love the atmosphere, you can catch the scent of it in many of the images in our galleries or come train with us. Tel Aviv is a fun city.

There are never guarantees that we’ll make a warrior from every new student, the only guarantee is that whatever we do, we do it with our extensive knowledge, our heart, taking no shortcuts, the way we see it.

  1. Risk assessment is not intuitive. “There were fewer cars on the road last spring during the height of the pandemic, but traffic fatality rates increased 30% in the second quarter as evidence suggests drivers engaged in more risky behavior, federal officials say. A second NHTSA study of trauma centers found seriously injured or fatal crash victims took risks during the pandemic that included speeding, driving impaired, and not using their seat belts. For example, the study revealed a higher prevalence of alcohol, cannabinoids, and opioids in crash victims during the quarter compared to the months prior to the pandemic.” (link)

  • The machine consists of three parts. There’s a “head,” which houses automated surgical tools and brain-scanning cameras and sensors, against which a patient situates their skull. A device first removes a portion of skull to be put back into place post-op. Then, computer vision algorithms guide a needle containing 5-micron-thick bundles of wires and insulation 6 millimeters into the brain, avoiding blood vessels. (Neuralink says the machine is technically capable of drilling to arbitrary lengths.) The wires — which measure a quarter of the diameter of a human hair (4 to 6 μm) — link to a series of electrodes at different locations and depths. At maximum capacity, the machine can insert six threads containing 192 electrodes per minute. (link)

Very interesting and original paper on the military capabilities of Israel against Sunni and Shiite hegemonies.
As a practitioner of the mainly symbolic discipline I do, it is a good reality check.

Here’s an excerpt,

The study assesses that a Sunni military threat, either with or without Turkey, could rapidly and unexpectedly emerge. The current combined military capability of the Sunni states is relatively limited compared to that of Israel, but over the long term, Israel would likely prove unable to maintain the decisive technological superiority it now possesses versus the current Sunni militaries. In such a scenario, Israel’s current exaggerated emphasis on combat with non-state light infantry, located within urban areas, under counter-insurgency rules of engagement would combine to compromise its long-term ability to cope with a Sunni conventional combined arms threat that could arise in the future.
