I can see the Japanese influence with the way the foot work is and I can see the additional
Chinese flavor in it to such as the leg lifting what is interesting is the use of it with one hand rather than using it with 2 hands. Most of the Japanese sword work I have seen is used with two hands as I was taught the top hand pushes down while the other hand is pulling up.
I would be interested in hearing how widely one hand was used(besides in typical Iaido type quickdraws)
Having been a butcher the knife makes a similar push and pull to allow easier gliding thru flesh.
I welcome corrections on this and admit openly Japanese sword work is not focus.
It was very nice to see the form and hard work involved.
