Re: Tamura's warm up
There are actually a couple of books out there, out of print but still available.
I (literally) picked up a copy at a garage sale a few years back and started paging through out of idle curiousity. A few pages in, I thought, "pieces of this look an awful lot like a standard aikido warmup, but there's much more detail here."
That book was:
The Ancient Tradition of Do-In 1 by Jacques de Langre
It deals primarily with hand and foot auto-massage technique.
The second volume is:
Do-in II by Jacques de Langre
There are others in the series, but these are the only two that I know to be available.
Definitely a period piece. I haven't seen a a one-piece short-shorts jumper like the one on the model for the photographs in more than a couple of decades.....
But what relationship Mr. De Langre's work has to traditional Chinese Dao Yin or to Tamura's workout I couldn't say.....
