The article is about century+ old businesses in general, of which family-run ones are a subset.
The article doesn't mention temples being burned down at all.
But you might still say "family run for a thousand years"
more as ad advertisement slogan though. I've never seen someone in the west adopt another adult just to authentically continue a legacy (outside of European monarchies maybe). There is a sense of tradition to these Japanese companies that one doesn't see so often outside of Japan.
Thoroughly agree.
Romans used to do adult adoptions. Off the top of my hat, I clearly remember that Cesar adopted Brutus, his killer, as an adult.
