Toughy. They're in a
Japanese home or apartment and speaking
Japanese. There is a fairly sizable community of South Americans living in
Japan as factory workers etc. so it's possible she's part of that community. This being a
Japanese video, it's likely you'd find her through the
Japan A/V websites. There may be a useful search phrase or term you'd need to use...can't recall what that may be.
Edit: she might be a "Nikkeijin" - Foreigner of
Japanese origin such as Brazilian 2nd or 3rd generation (Nisei or Sansei) who has emigrated to
Japan, temporarily or permanently.
Or not. Maybe she's a student or other
Japan resident. But I agree with you she definitely looks latin.
So I'd try, in the
Japan AV databases, to look for "latin" or "brazil" or "nikkeijin" or other such terms.
Hopefully this steers you in the right direction good luck.
