Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

My last name is "Akuta" and I have only had inquisitive responses from other Polish people because it didn't "seem" polish. Just after WW2 my father came here to Canada after being in work camps and I was wondering if it was common to change the last name in that time. The only people I have found with this last name are from an Asian background. Just curious.
