One of the things that has been nagging at me is the way Beatrice is described in the epitaph. Something to be 'awakened' and then 'put back to sleep.'

It seems likely to me that the witch in the poem is not a witch in the traditional sense, but a place/process/thing/contact that enables the the finding/making of gold/money.

The following is my own speculation, strongly influenced by why someone in fiction usually hides such things in a poem/riddle in books/movies.

Spoiler for My dumb theory:

Now if Kinzo has access to this whatever it is, why does he hide it? Why would you have to put 'her' back to sleep?

Given that Kinzo made his fortune after the war, and in the wake of an earthquake, the easiest explanation would be a mine, or hidden treasure trove of gold, perhaps being spirited out of Japan once the people in charge realized they were going to lose. Or maybe it was sent by the Germans to the Japanese to help fund the war against the Americans. After all, the eagle was a sign of the Nazi party. Maybe that's where the family got its crest from? Do we know if that predates Kinzo or not? This kind of thing is fairly common in fiction, you see stuff like it in manga/movies all the time (the Nazi arc in Black Lagoon, or the Indiana Jones movies spring to mind).

Now, Kinzo would probably not want it widely known that he was financing his own little empire with ill-gotten gains from a previous war. The 'self-made man' is actually feasting like a vulture on money that probably belongs to the Japanese, German, or American government. And we also know that he is not super impressed with his current heir. What better way to find an heir/ensure the safety of the secret of his fortune, than to make sure that it could only be accessed by someone clever enough to figure out his little riddle.

I think this also reconciles with, and I'm trying to avoid spoilers here, some of the things we learn in Episode 3.

Spoiler for Weaknesses and my responses:

Some weaknesses to account for: (1.) Says nothing about all the twilight stuff/where the gold is hidden. I have no idea what's going on there, but I agree with the general consensus that it's a word game that is trying to give us a long/latitude or location name. Or even a person's name.

(2.) I have to struggle to explain the resurrection of 'all the dead' and 'even the lost love.' But maybe by resurrection they mean bringing to light what is dead/unknown. Maybe the war gold is surrounded by bodies and such like the Nazi Sub in Black Lagoon? Or in the movie Goonies, with the dead pirates? Maybe Kinzo is assuming whoever finds the gold will lay the bodies to rest, give them a chance at resurrection. And resurrection of the lost love? Maybe Kinzo's lost love (also named Beatrice perhaps) is laid to rest there. Maybe they fought over the gold, and he would finally like to see her at peace (especially now that he knows he is dying).

Another possibility is that his lover is still alive, in which case Beatrice does refer to a person but she's not a witch in the sense that she knows magic, just that she knows where the gold is (and interestingly witches in the Old Testament were originally defined as those who laid/had congress with the devil...Kinzo=the Devil perhaps? Maybe I'm reaching here). And the location/name pointed to in the epitaph stuff about twilights and such is meant to point you toward her as a contact/middleman to the gold. Resurrection in this sense would mean giving her/her family a share of the gold. This might be appealing considering how suspicious/intriguing the servants act and we know that they are more than they appear to be.
