I fail to see how spouses having the same name has any impact on the distribution in the future, the factor that controls that is the names of the children. To fix this you’d need to do something along the lines of girls get the dad’s surname, boys the mother’s, or the other way around. Also Spanish customs are worth looking at.
This assumes that they only ever have the names they have now. Call me crazy, but I suspect that immigration policies will probably shift a little at some point in the next 500 years.
Hell, I wouldn’t even be willing to bet that any given country would still be around in it’s current form by then, including Japan.
A lot of names came from locations and professions. For example, not every "miller" or "smith" is related to one another (well, any more so than every human is related to another)
using De Morgan’s negation rule this is equivalent to
⇔ ∄ P ∈{X | X lives in Japan} : P is not named Sato
Since {X | X lives in Japan} = ∅ is the empty set, such a person P can by definition not exist. Which means, the first statement is true. If no person lives in Japan, that means every person living in Japan is named Sato.
For one, there is no legal requirement that a Japanese partner take the name of their foreign spouse (in fact, it's basically the exception to the rule that all married couples must have the same surname).
The assumptions are almost certainly going to turn out to be incorrect, but even if everyone ends up with the name Sato, people will just start adding other names to differentiate, like they’ve done in cultures throughout history.
“If everyone becomes Sato, we may have to be addressed by our first names or by numbers,” he said, according to the Mainichi. “I don’t think that would be a good world to live in.”
Not anyone find it good to be called by first name. And japanese culture is very attach to last name naming or I should say family name cause their are placing it the other way around.
