Obama's birthplace (4)

I believe the answer is:

oahu

'obama's birthplace' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for oahu that I've seen before include "Honolulu's island" , "Hawaiian island" , "Pacific island" , "popular Pacific location" , "Chief island of Hawaii" .)

I've seen this clue in The Wall Street Journal.
