You’re not understanding the difference: in most of the world, businesses are carried on because there’s some financial value derived from it, not for the thing itself. Family businesses do exist, and do get passed down, but if the owners of the business don’t have any natural heirs, they’ll wrap it up or sell it. That’s normal.

In Japan, the longevity of the thing has a value of its own, so much so that they’ve invented adult “adoptions”, simply to keep an old business going. The business could be mediocre and barely profitable, but if it’s 300 years old, they’ll find a way to keep that line going.

Maybe they exist, but I’m not aware of any other culture that has taken up the practice of adopting adult males to ensure that a family business remains “family”.
