If a US-Japan dual citizen, who has work history in the US with US citizenship, moves to Japan with a Japanese passport, and then works in a Japanese company as a Japanese citizen, does that person need to file taxes to the IRS as a US citizen who makes income in Japan as a Japanese citizen? Or would it be acceptable to separate the citizenship (as if there are two separate people), thus signifying that the individual, as a US citizen, has zero income in neither the US nor Japan and does not need to file taxes to the IRS.
