Cutting Bamboo in Ibaraki
Not really iaido, but maybe of interest.
In my last trip to Japan - which was awesome - I had the opportunity to to some bamboo tameshigiri in yoroi on a day trip to Ibaraki. It was my first time cutting bamboo and my first experience to wear armour.
The most interesting part was wearing the kabuto. It interferes with my typical postures and movements. You can see me hit the maedate (the crest) several times, and I have to constantly readjust to account for the helmet.
On this same trip I earlier had the chance to experience Jikishinkage Ryu which is a "katchū" kenjutsu - armoured context. It was a struggle being so different from Itto Ryu. So this was an immediate illustration so some of those aspects.
I cut with fairly minimal power. It's not necessary - only focus and correct hasuji. Each fail you see is simply a lapse in concentration - there was a lot going on (the people around me, the condition of the sword, the helmet and armour, etc.) - and was immediately corrected.
Anyway, really great and fun experience!
