I believe her Mother is Japanese.
If her “mother” is “Japanese” (or some other South East Asian) is of no importance, in this case - see the issues I was raising in previous FR link June 2007.
I, personally, know Iranians born in Iran with “Iranian” parent(s), who have been mistaken, based on their looks, for being part or full South East Asian (Japenese are considered South East Asians too). The mentioned gene pool regarding Iran is too true to date.
However, the issue, for the IRI is her father, who was/is Iranian born or an Iranian Citizen; since she, herself, was not born in Iran, but obviously must carry an Iranian Passport, and, more importantly, an Iranian lastname in it.
Anyway, she would not have never been issued, nor permitted to hold a Mullah-regime’s passport without the Mullahs’ being satisfied to grant her one based on her father’s birth or citizenship at least.
Of course, the political factors, as mentioned, regardless of ethnicity, also remain.
