Decoding “Japanese Attacks”
Why We Train at Half-Speed in Iwama Aikido? In the modern world of martial arts, heavily driven by social media algorithms, there is a dangerous illusion. People are often promised that a few years of high-intensity sparring will instantly turn them into unstoppable fighters.
At our dojo in Stevenage, we choose a different path: the path of rigorous body mechanics, geometry, and structured progression.Lately, we have been incorporating contemporary attacks, such as boxing combinations and takedown attempts, into our 1-on-1 randori practices. However, we intentionally do this at half-speed.To the untrained eye, slowing down might look counterintuitive. But in reality, it is one of the most powerful pedagogical tools in traditional budo. Here is why:
1. Understanding Geometry and Timing (Deai)
Training at half-speed gives the brain and the nervous system the luxury of time. It allows the practitioner to register the exact moment of entering the opponent’s timing (deai). Instead of reacting with panic or stiffening up out of fear of getting hit, the student learns to relax, step off the line of attack (tai sabaki), and maintain control of the center. It allows veterans to physically spot their long-standing errors and gives naturally gifted students the perfect playground to refine their coordination.
2. The Truth About “Japanese Attacks”
People outside of traditional arts often look at classic movements like Shomenuchi or Yokomenuchi and dismiss them as archaic, impractical “samurai strikes.” But this completely misses the genius of traditional Japanese methodology.In Iwama Aikido, these strikes are not technical flaws by the attacker—they are deliberately exaggerated, highly signaled structures of movement. In other words, traditional Japanese attacks are the original version of half-speed training.By offering a large, clear, and committed overhead or diagonal strike, the attacker provides a safe, predictable frame. This frame allows the defender to hardcode correct physical habits into their muscle memory: perfect posture (kamae), driving power from the hips (hara), and flawless distance management (ma-ai).
3. Transitioning to the Chaos of Today
Once the underlying physics and geometry are deeply understood through katai-keiko (rigid, heavy basic training) and classic strikes, they can be universally applied to anything. By taking modern, chaotic boku-style punches and slowing them down to half-speed 1-on-1, we bridge the gap between tradition and reality. We prove that the principles laid down by Morihiro Saito Shihan are not museum pieces. They are universal laws of human biomechanics.
Final Thought
Martial arts were never meant to be a “fast food” experience. Real defensive skills and deep body awareness take time to cultivate. By slowing down the tempo and dissecting the mechanics, we don’t look for flashy internet magic—we look for the truth in movement. Whether you are a seasoned martial artist looking to understand deeper structure, or a complete beginner wanting to learn real craftsmanship, our doors at the Shephall Community Centre are always open. Come down, step on the mat, and feel the physics for yourself.
Training times: Mondays & Wednesdays (19:00 – 20:30), Sundays (10:30 – 12:00) at Shephall Community Centre, SG2 9XR.
First three sessions are always free. No experience required.
Fantastic way to train and inject realism into the techniques so often practice by other styles and clubs in a rehearsed, robotic way.
You really get to see the opportunity to use techniques even if your skill level or confidence is lacking to perform them. This practice helps you develop the awareness and ability to start using class based curriculum in situations that call for you to remain calm, relaxed and ready. More importantly believe in your training and abilities to expand the how and why techniques are devised the way they are and the movement required.
Not forgetting to ensure that you begin and end in Hanmi to deliver the body strength via movement and the stability the stance offers.
All around a great exercise to develop and expand your Iwama Aikido skills and awareness to is full potential.
