Do you have Japanese citizenship? Ending up stateless doesn't seem worth it.

I may be wrong, but I believe if not so the US legally can't allow him to renounce his citizenship.

(Allowing a person to become stateless is illegal if I remember correctly, but my memory's ever-so-slightly fuzzy around this topic.)

My wife is Japanese and obtaining citizenship would be fairly easy. I agree on not ending up stateless.
