When asking another person where they are from, one can use either of the two options below:

(A) ご出身は (go shusshin wa?), In English, it means, “Your hometown/origin?”

(B) ご出身はどこですか (goshusshinwa doko desuka?) which means “Where is your birthplace/hometown?” Or “As for your birthplace, where is it?”

Option B is an XはYです (X wa Y desu) sentence pattern. That is, X = Y.

X is ご出身 (goshusshin) and Y isどこ (doko).

Your hometown/origin = where?

When replying to the question, replace どこ (doko) with the answer.

Country + 人 is used to describe one’s nationality.  人 (jin) means “person” or “people”.

何 (nani) means what.

何人 (nani jin), literally means what person. It means “what nationality” (are you)?”

何人ですか (nani jin desuka), a full sentence, is use to ask “What nationality are you?” or “What is your nationality?”
