So some random guy walked by while I was underwater…and apparently stunned him a bit with my antics…You can hear his footsteps on the bridge in the beginning clip.
On to the more pertinent things.
Sui-jutsu or ‘water arts’ (swimming with armor, hiding in water ‘sui-ton’, etc.) were a component to ninjutsu. In this vid., I exhibit how to hide yourself in moving currents using a grappling hook (aka kaginawa) and branches buried in the sand after a warm-up (most not on cam..but will try harder next time) Be safe and remember…I am not responsible for your misdeeds.
