4. I practice karate, kobudo and aikido. A year ago I started iaido. In all Martial Arts you turn your body in an angle towards your Partner so you give less space to get hit. In iaido-kata you stay full broadside. Is there a reason for it? Comments: My Teacher didn't know it, and has not even considered this up to now. He is more a sportive type while I'm more interested in traditional ways where almost everything has a special meaning. Jochen - Germany -

... Your question is very interesting and we have given it some thought which you no doubt will be able to expand on as your training progresses.
... We must remember that traditional martial arts have evolved from practical ways. To respond in a self-defence situation requires being able to move from a natural stance in any direction. In iaido, the formal training presumes an attacker who is also drawing a sword. Except for a few techniques which involve direct forward thrusts or downward strikes, the weapon is wielded in a circular trajectory. The effect of turning to the side would in this case offer more vulnerable surface area as a target than facing the opponent front on.
... Also, in order to successfully counter a sword attack by moving away and deflection of the blade (using two hands) you would not want to find yourself overly committed to one side and unable to twist behind you. One handed sword work, as you might find in fencing with a lighter blade, would occasion a different technical response.
... The physics of controlling the blade for accuracy and overcoming its inertia in preparation for the next move, also demands a certain position of the hips as the blade passes across the center of the body.
... It is also possible that psychologically the effect of facing your fate calmly and directly can be more intimidating to the attacker.
... These are some thoughts to ponder as you practice.
