... the present situation in Japan, ... You would have: (1) a separate and self-contained aikido organization for the entire US military, with its own shihans and distinctive ways of training; (2) a separate and self-contained aikido organization for the US Senate and House of Representatives, again, with shihans and distinctive ways of training; (3) a separate and self-contained organization for the huge industrial corporations, again with its own shihans and distinctive ways of training; (4) a separate and self-contained organization for students of all the major US universities, again with its own shihans and distinctive ways of training.
So cultural pattern repeats itself -- the shugo become daimyo. A thousand years is too short a time for a nation to change its basic forms of spontaneous social organization.
This would not happen in the U.S. because our patterns of organization are much different. Patterns such as these tend to very be durable aspects of culture, surviving tremendous physical and socio-economic dislocations, and are far deeper than mere politics. In Hofstede's trope, I would view these as cultural "firmware." I would not be terribly surprised to find that as a theme in his project trying to extend Jungian psychological typology into the sociological dimension of national cultures.
If such patterns are that durable, though, and the daimyo are staking their provinces, the question is -- are the sengoku far behind? And if so, is Hombu now tending to imitate the "imperial" aloofness as a matter of retaining its paramount position, at the expense of real influence. And if so, is this creating another vacuum in that role, which, in their pattern, must
be filled for all the parts to function, and thus begging for the functional repeat of the bakufu in miniature?
