Sounds like my mom’s side of the family.

Let me verify it with my son later. My wife said I’m crazy talking about bound feet and opium but I’m sure of it.

Ok, so from what I understand there’s 3 things one can get from the household registration office.
A current copy of HHR.
A HHR that goes back a few generations. My wife got one back to her great grandparents or grandparents time for that in order to apply for some kind of scholarship for our son. Some universities give scholarships if past generations didn’t have a uni education.
And then in some cases there’s copies of Japan occupation period HHR papers (日治時期戶籍謄本)
I recall it took a few days. Our son had to do it for a HS assignment. It’s done through the same office.
Google search that and a lot of information comes up including images.
Basically like some western census reports with certain details that were important at the time.
Here’s an example I found on a Google search.
Looks interesting. Thanks!
