The Peaceful Martial Art

Me and my teacher Ichimura sensei, way back in 1974. The video above is from 2007, at my present dojo Enighet in Malmö, Sweden. The photo to the right is from 1974, with an adolescent me as uke to Ichimura sensei, my aikido teacher at that time.

       Now, I have practiced aikido for more than 40 years. How many hobbies will last for that long, and remain fascinating? Normally I am impatient, to say the least. Anything that I have to repeat over and over will very quickly lose its attraction.

       Not so with aikido, the gentle martial art from Japan. I keep on doing those exercises, keep on struggling to refine the aikido techniques - and my fascination increases. This is an anomaly, a koan if you will, that can only be comprehended if aikido is seen neither as a sport nor a system of self defense, but as an art.

       Of course aikido is an art. Endlessly intriguing, infinitely variable, never perfected - what else could it be?

       Scroll down to check out all the aikido material I have on this website. I hope you find it interesting.

Aikido videos

Aikido Video Clips

kotegaeshi Several aikido video clips - both from seminars and from instructional recordings. In some of them I do rather improvised versions of basic and not so basic aikido techniques, in others I stick to basic forms for clarity.

Aikido Knife Defense

Tantodori Tantodori, aikido defense against knife attacks - some techniques. This is focused on how to take the knife from the attacker at the end of the technique, something that many aikidoka do without enough care.

Jo 31 kata.

Jo 31 Kata

The jo 31 kata in four directions. The traditional 31 kata practiced in aikido is in two directions - front and back - but that is odd for a kata with so many movements. At my dojo, we have allowed ourselves to modify it into a four directions kata. See how we do it, and see if you approve or not.

OMOTE - kesagiri.


Aikido sword exercises with partner and bokken, or solo like iaido. There are some very complex systems of sword exercises in aikido, often demanding a high strain on one's memory at the cost of properly exercising the sword technique fundamentals. This is a simple exercise system we use at my dojo. I call it aikibatto, since it combines aspects of aikido with those of iaido (batto).

Aikido as self-defense.
