Jokes on him. He is still on British colonial territory.

There was only one shogun (when there was any). The emperor > shogun relationship was not at all like emperor's relationship with kings or imperial subjects in the Holy Roman Empire for instance.

The shogun *nominally* ruled on behalf of the emperor but in fact the emperor was a ceremonial figure and had no actual power (except, perhaps, at the outset of the Ashikaga Shogunate, when there was what we might think of as a civil war between pro- and anti-Ashikaga factions, one of which was "imperial").

Sometimes the shogun was themselves a figurehead - eg during much of the Kamakura Bakufu when it was the Hojo regents that were actually in control or at least nominally so.

Daimyo are more complicated and a bit more like feudal subjects in the Reich sense. But only a bit.

It sounds like a version of sorites for minds.

Intriguing. You don't happen to remember the name of the film do you?

While religion was certainly a significant element in the war, it was not really a religious war. Consider that the war was ended by an alliance between Gustavus Adolphus (a leading Protestant monarch) and Cardinal Richelieu (whose religious affiliation you can guess from the name).

You are forgetting that Edward I and Patrick McGoohan are/were exactly the same height. They got that right :-).
