Okay, I just procrastinated reading up about this stuff on Wikipedia, so you know everything I'm about to say is definitely going to be 100% correct, yep.

>it's Hyakumangoku (place name), not hyaku man koku (one million koku)

Regarding the reading - Yes, hyakumangoku is the correct reading, as is shown in the romaji lyrics. It's written as koku in the English because in the English I split it off from the 'one million', thus the weird rule that occasionally makes kanji joined together slightly change in reading doesn't really apply.

>Hyakumangoku is the modern name of what was previously Kaga province

About the place(?) - As far as I can see, there is currently no place named hyakumangoku that isn't, like, a restaurant or something in modern times. There doesn't seem to have been any place in the past either, although the concept of hyakumangoku seems to have been basically synonymous with the Kaga Domain (加賀藩), which was within a few different districts (石川郡、能美郡、河北郡) which were within the former Kaga Prefecture (加賀国) that Kaga was named after. Since the typical measure of wealth, and by extension, physical possessions back then in Japan was measured in rice production power (rather than actual land) and one million koku was such a ridiculously large amount (more than other person/place/clan/han), it's entirely possible that the Kaga Domain may have been referred to by the amount of wealth they had. The actual name of the place, however, would probably still be Kaga Domain.

On interpretations of the lyrics - Interpretations are interpretations, so you shouldn't need to worry about making anybody feel wrong. You're certainly taking it from a POV I didn't really consider, which would be from the actual character's POV.
