> Japan is one of those countries that doesn’t allow dual citizenship and they require proof of renunciation.
Japan doesn't allow dual citizenship if you acquire the japanese one later in life.
Plenty of people in Japan, like my nephew, have dual citizenship by birth. I don't know if they can keep both when they're adult. But as kids 100% guaranteed Japan allows it.
And then a great many mixed couple do, on purpose, give literally two different identities to their kids. One by registering them, say, in Germany with the name written in roman characters (say "Akane") and the other in Japan with the name written using kanjis (or kanas for that is allowed to).
I'm not talking about dual citizenships / two passports: I'm talking about the same person having two entirely different identities because his parents registered him, on purpose, differently in two different countries.
So, yes, there are literally a few people counted twice on earth. And you probably don't want to do that with the US citizenship (for US taxes its citizens worldwide and it's a reporting clusterfuck). But if you've got, say, a japanese identity and whatever european one: you're totally fine.
